     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
    
 
   
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
    
 
   
A:   No.
    
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
   
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
    
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
   
A:   In June, 1997, we acquired the managing general partner of your partnership
     (the "general partner"). In 1997, we also acquired a 95% non-voting
     interest in the company that manages the property owned by your
     partnership.
    
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
   
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
    
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
    
 
                                       S-1
<PAGE>   7
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
   
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
    
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
   
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
    
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   8
 
   
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
    
 
   
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
    
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
   
A:   There are two principal advantages of tendering units for cash:
    
 
   
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
    
 
   
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
    
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
   
A:   Your partnership did not pay any distributions on your partnership's units
     in 1998. We will pay fixed quarterly distributions of $               per
     unit on the Tax-Deferral   % Preferred OP Units before any distributions
     are paid to holders of Tax-Deferral Common OP Units. We pay quarterly
     distributions on the Tax-Deferral Common OP Units based on our funds from
     operations for that quarter. For the six months ended June 30, 1998, we
     paid distributions of $1.125 on each of the Tax-Deferral Common OP Units
     (equivalent to $2.25 on an annual basis).
    
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
   
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
    
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
   
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
    
 
   
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL

     TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX
     CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
     TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX
     MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS
     AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX
     CONSEQUENCES TO YOU OF THE OFFER.
    
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
   
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
    
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
   
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated. In August, 1997, we offered to acquire all
     units of your partnership at a price of $2,648 in cash per unit. In June,
     1998, we offered to acquire all units of your partnership at price of
     $21,668 in cash per unit.
    
 
   
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
    
 
   
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
    
 
   
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
    
 
   
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
    
 
   
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
    
 
   
A:   We divided the cash offer consideration by $     , which represents the
     closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
    
 
                                       S-4
<PAGE>   10
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
   
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
    
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
   
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
    
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
   
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
    
 
THE AIMCO OPERATING PARTNERSHIP
 
   
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
    
 
   
     - owned or controlled 58,495 units in 209 apartment properties;
    
 
   
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
    
 
   
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
    
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
   
     In exchange for each of your units, we are offering you a choice of:

RISK FACTORS
 
   
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
    
 
   
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
    
 
   
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
    
 
                                       S-7
<PAGE>   13
 
   
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
    
 
   
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
    
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
   
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
    
 
   
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
    
 
   
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
    
 
   
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
    
 
   
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
    
 
   
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
    
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   14
 
   
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
    
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
   
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
    
 
   
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
    
 
   
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
    
 
   
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
    
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
   
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
    
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   15
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
   
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
    
 
   
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
    
 
   
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
    
 
   
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
    
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
   
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
    
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   16
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
   
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
    
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
   
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
    
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
   
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
    
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
   
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
    
 
                                      S-11
<PAGE>   17
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     In June, 1997, we acquired the general partner of your partnership. In
1997, we also acquired a 95% non-voting interest in the company that manages the
property owned by your partnership. We conducted two prior tender offers for
units of your partnership. In August, 1997 we acquired a 0.7576% limited
partnership interest in your partnership through the first tender offer. In June
1998, we acquired an additional 0.3788% limited partnership interest in your
partnership through the second tender offer. We currently own a 1.1364% limited
partnership interest in your partnership.
 
   
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
    
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
   
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
    
 
   
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership has required funding from its partners. Continuation of its
     operations is dependent on additional funding from partners or from other
     sources. Your partnership faces maturity
    
 
                                      S-12
<PAGE>   18
 
     or balloon payment dates on its mortgage loans and must either obtain
     refinancing or sell its property. If your partnership were to continue
     operating as presently structured, it could be forced to borrow on terms
     that could result in net losses from operations. In addition, continuation
     of your partnership without the offer would deny you and your partners the
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
   
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
    
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
    
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
   
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax Deferral      % Preferred OP
       Units rank equal to six other outstanding classes of Partnership
       Preferred Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
    
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
    
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
   
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
    
 
   
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
   
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %
Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any combination
of such forms of consideration for your units. The offer is made upon the terms
and subject to the conditions set forth in this Prospectus Supplement, the
accompanying Prospectus and the accompanying Letter of Transmittal, including

to time (the "Letter of Transmittal"). To be eligible to receive Tax-Deferral
     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered

     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
   
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
    
 
   
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
    
 
   
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.

     Extension; Termination; Amendment. We expressly reserve the right, in our

                                      S-14
<PAGE>   20
 
   
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
    
 
   
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
    
 
   
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
    
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
   
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
    
 
   
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
    
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
   
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
    
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY

     BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR
TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN
THIS PROSPECTUS SUPPLEMENT AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO
STOCKHOLDERS," "FEDERAL INCOME TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND
OP UNITHOLDERS" AND "OTHER TAX CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND
CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO
YOU OF THE OFFER.
    
 
VALUATION OF UNITS
 
   
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
   
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
    
 
   
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
    
 
   
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
    
 
   
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
    
 
   
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
    
 
   
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
    
 
   
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
   
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our consideration from a financial point of view.
The full text of the opinion, which contains a description of the assumptions
and qualifications made, matters considered and limitations on the review and
analysis, is set forth in Appendix A-1 and should be read in its entirety. We
imposed no conditions or limitations on the scope of Stanger's investigation or
with respect to the methods and procedures to be followed in arriving at the
fairness opinion. We have agreed to indemnify Stanger against certain
liabilities arising out of its engagement to render the fairness opinion. Based
on its analysis, and subject to the assumptions, limitations and qualifications
cited in its opinion, Stanger concluded that our offer consideration is fair to
you from a financial point of view.
    
 
   
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
    
 
   
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
    
 
                                      S-17
<PAGE>   23
 
   
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner.
    
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
   
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
    
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
   
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and a 95% non-voting interest in
the manager of your partnership's property. The general partner of your
partnership receives a fee of $2,083 per month from your partnership and may
receive reimbursement for expenses generated in its capacity as general partner.
The property manager received management fees of $427,385 in 1996, $437,571 in
1997 and $215,708 for the first six months of 1998.
    
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
   
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
    
 
   
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
    
 
YOUR PARTNERSHIP
 
   
     Your Partnership and its Property. Casa Del Mar Associates Limited
Partnership is a Florida limited partnership which was formed on August 26, 1998
for the purpose of owning and operating an assisted living apartment property
located in Boca Raton, Florida, known as "Casa Del Mar." In October, 1988, it
completed a private placement of units that raised net proceeds of approximately
$7,400,000. Casa Del Mar consists of 214 apartment units. Your partnership has
no employees.
    
 
   
     Property Management. Since July 12, 1996, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of
    
                                      S-18
<PAGE>   24
 
   
equipment and supplies, and the selection and engagement of all vendors,
suppliers and independent contractors. The property manager is affiliated with
us.
    
 
   
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2038, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
    
 
     Borrowing Policies. Your partnership agreement allows your partnership to
incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $13,800,862, payable to Mellon Bank MD, which bears interest at
the rate of 8.12%. The mortgage debt is due in August 2005. In addition, your
partnership had borrowed $1,714,490 (including accrued interest) from an
unrelated party on an unsecured basis as of June 30, 1998. The majority of these
borrowings bear interest at 9% and are due July 2006. Your partnership agreement
also allows your general partner to lend funds to your partnership. As of June
30, 1998, your general partner had outstanding loans (including accrued and
unpaid interest) of $5,906,796 to your partnership, which generally bear
interest at a rate of 9% and mature in July 2006.
 
   
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
    
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
    
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
   
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
   
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
    
 
   
     - owned or controlled 58,495 units in 209 apartment properties;
    
 
   
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
    
 
   
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
    
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
   
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
    
 
   
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
    
 
   
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
    
 
   
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
    
 
   
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
    
 
                                      S-26
<PAGE>   32
 
   
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
    
 
   
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
    
 
   
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
    
 
   
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
    
 
   
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
    
 
   
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
    
 
                                      S-27
<PAGE>   33
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
   
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
    
 
   
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
    
 
   
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
    
 
   
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
    
 
   
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25 and the estimated 1998
distributions of $0 with respect to your units, distributions with respect to
the Preferred OP Units and Common OP Units to be received in the Offer are
expected to be greater, immediately following the offer, than the distributions
with respect to your units. See "Comparison of Ownership of Your Units and AIMCO
OP Units -- Distributions."
    
 
   
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
    
 
   
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
    
 
   
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
    
 
   
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
    
 
                                      S-28
<PAGE>   34
 
   
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
    
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
   
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
    
 
   
     On June 3, 1997, the Company acquired NHP Partners, Inc., a Delaware
corporation ("NHP Partners"), and NHP Partners Two Limited Partnership, a
Delaware limited partnership ("Partners Two"), each formerly affiliated with NHP
Incorporated, a Delaware corporation ("NHP"). As a result of this acquisition,
the general partner of your partnership became a subsidiary of AIMCO and an
affiliate of the AIMCO Operating Partnership. Previously, on May 5, 1997, AIMCO
acquired 51.3% of the outstanding common stock of NHP, which manages the
property owned by your partnership. On December 8, 1997, AIMCO acquired the
remaining 48.7% of the outstanding common stock of NHP and thus owns 100% of the
outstanding common stock of NHP.
    
 
   
     We conducted two prior tender offers for units of your partnership. In
August, 1997 we acquired a 0.7576% limited partnership interest in your
partnership through the first tender offer. In June 1998, we acquired an
additional 0.3788% limited partnership interest in your partnership through the
second tender offer. We currently own a 1.1364% limited partnership interest in
your partnership.
    
 
  Engagement of Fairness Opinion Provider
 
   
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
    
 
ALTERNATIVES CONSIDERED
 
   
     One of the reasons AIMCO acquired NHP Partners, Partners Two and NHP was
that AIMCO expected to make offers to acquire limited partnership interests of
some of the limited partnerships formerly controlled or managed by NHP (the "NHP
Partnerships"). Such offers would provide liquidity for the limited partners of
the NHP Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain NHP
Partnerships which would provide a larger asset and capital base and increased
diversification.
    
 
                                      S-29
<PAGE>   35
 
   
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
    
 
  Liquidation
 
   
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
    
 
   
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
    
 
   
  Continuation of the Partnership Without the Offer
    
 
   
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
    
 
   
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership has required funding from its partners. Continuation of
its operations is dependent on additional funding from partners or from other
sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
    
 
   
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
    
 
EXPECTED BENEFITS OF THE OFFER
 
   
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership

interest in the property owned by your partnership while providing you and other
investors with an opportunity to retain or liquidate your investment or to
invest in the AIMCO Operating Partnership.
    
 
   
     There are four principal advantages of tendering your units for Preferred
OP Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
    
 
   
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax Deferral   % Preferred OP Units rank equal to five other
       outstanding classes of Partnership Preferred Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
    
 
   
     There are five principal advantages of tendering your units for Common OP
Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
    
 
   
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your partnership has not paid any distributions on your units
       since the inception of your partnership. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
    
 
   
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
    
 
   
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
   
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
    
 
   
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
    
 
   
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
    
 
   
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
    
 
   
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
    
 
   
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
    
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
   
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
    
 
                                      S-32
<PAGE>   38
 
   
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
    
 
   
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
    
 
   
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998 IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
    
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
   
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
    
 
  Signature Requirements
 
   
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
    
 
   
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
    
 
                                      S-33
<PAGE>   39
 
   
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
    
 
  Appointment as Proxy
 
   
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
    
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
   
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
    
 
  Election of Consideration
 
   
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
    
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   40
 
   
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
    
 
  Backup Federal Income Tax Withholding
 
   
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
    
 
  FIRPTA Withholding
 
   
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
    
 
  Binding Agreement
 
   
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
    
 
WITHDRAWAL RIGHTS
 
   
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
    
 
   
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
    
 
   
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
    
 
   
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
    
 
                                      S-35
<PAGE>   41
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
   
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
    
 
   
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
    
 
   
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
    
 
PRORATION
 
   
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
    
 
                                      S-36
<PAGE>   42
 
   
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
    
 
   
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
    
 
   
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
    
 
   
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
    
 
   
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
    
 
FRACTIONAL OP UNITS
 
   
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
    
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
   
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
    
 
   
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
    
 
   
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
   
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
    
 
DISSENTERS' RIGHTS
 
   
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

units tendered, and may terminate or amend the offer if at any time from or
after           , 1998 and at or before the time of acceptance for payment of

     Partnership, might affect the extension of credit by banks or other lending
     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or
    
 
   
          (c) there shall have been threatened, instituted or pending any
     action, proceeding, application or counterclaim by any Federal, state,

          (f) a tender or exchange offer for any units shall have been commenced
     or publicly proposed to be made by another person or "group" (as defined in

                                      S-39
<PAGE>   45
 
   
     acquire beneficial ownership of more than four percent of the units, or

     otherwise, to acquire beneficial ownership of more than four percent of the
     units, or (ii) any person or group shall have entered into a definitive

     The foregoing conditions are for the sole benefit of the AIMCO Operating
Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
   
  Future Control by AIMCO
    
 
   
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also
indirectly owns a 95% non-voting interest in the company that manages your
partnership's property. In the event that the AIMCO Operating Partnership
acquires a substantial number of units pursuant to the offer, removal of the
property manager may become more difficult or impossible.
    
 
  Distributions to the AIMCO Operating Partnership
 
   
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
    
 
  Partnership Business
 
   
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
    
 
CERTAIN LEGAL MATTERS
 
   
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
    
 
                                      S-40
<PAGE>   46
 
   
of any such action, there can be no assurance that any such additional approval
or action, if needed, would be obtained without substantial conditions or that
adverse consequences might not result to your partnership's business, or that
certain parts of your partnership's business might not have to be disposed of or
other substantial conditions complied with in order to obtain such approval or
action, any of which could cause the AIMCO Operating Partnership to elect to
terminate the offer without purchasing units hereunder. The AIMCO Operating
Partnership's obligation to purchase and pay for units is subject to certain
conditions, including conditions related to the legal matters discussed in this
section.
    
 
   
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
    
 
   
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
    
 
   
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
    
 
FEES AND EXPENSES
 
   
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
    
 
ACCOUNTING TREATMENT
 
   
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
    
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   47
 
RANKING
 
   
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
    
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
   
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
    
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-42
<PAGE>   48
 
Parity Units shall be declared ratably in proportion to the respective amounts
of distributions accumulated, accrued and unpaid on the Preferred OP Units and
accumulated, accrued and unpaid on such Parity Units. Except as set forth in the
preceding sentence, unless distributions on the Preferred OP Units equal to the
full amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
   
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
    
 
LIQUIDATION PREFERENCE
 
   
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
    
 
                                      S-43
<PAGE>   49
 
shall have been made in full to the holders of Preferred OP Units and any Parity
Units to enable them to receive their Liquidation Preference, any Junior Units
shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
   
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
    
 
VOTING RIGHTS
 
   
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
    
 
RESTRICTIONS ON TRANSFER
 
   
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
   
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
    
 
   
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
    
 
   
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
    
 
   
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
    
 
   
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
    
 
                                      S-45

in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
   
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
    
 
   
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
    
 
   
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
    
 
   
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
    
 
   
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
    
 
   
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
    
 
   
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
    
 
   
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
    
 
                                      S-50
<PAGE>   56
 
   
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
    
 
   
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
    
 
   
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
    
 
   
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
    
 
   
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
    
 
ADJUSTED TAX BASIS
 
   
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
    
 
                                      S-51
<PAGE>   57
 
   
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
    
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
   
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
    
 
   
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
    
 
PASSIVE ACTIVITY LOSSES
 
   
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
    
 
   
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
   
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
    
 
   
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
    
 
                               VALUATION OF UNITS
 
   
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
    
 
   
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's forecasted annual net operating income of
       $          for the period from January 1, 1998 to December 31, 1998 to
       derive a gross property value of $          . We selected a
       capitalization rate of      %, based on our experience in valuing similar
       properties. The lower the capitalization rate applied to a property's
       income, the higher its value. We considered local market sales
       information for comparable properties, estimated actual capitalization
       rates (net operating income less capital reserves divided by sales price)
       and then evaluated your partnership's property in light of its relative
       competitive position, taking into account property location, occupancy
       rate, overall property condition and other relevant factors. The AIMCO
       Operating Partnership believes that arms-length purchasers would base
       their purchase offers on capitalization rates comparable to those used by
       us, however there is no single correct capitalization rate and others
       might use different rates. We subtracted from this gross valuation
       capital expenditures of $          to derive a gross property value of
       $          .
    
 
   
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, as of June 30, 1998, of the
       non-real estate assets of your partnership, and deducting the liabilities
       of your partnership, including mortgage debt and debt owed by your
       partnership to its general partner or its affiliates after consideration
       of any applicable subordination provisions affecting payment of such
       debt. We deducted from this value any taxes and certain other costs
       including required capital expenditures and deferred maintenance to
       derive a net equity value for your partnership of $          .

     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
   
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
    
 
                                      S-54
<PAGE>   60
 
   
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
    
 
   
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
    
 
   
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
    
 
   
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
    
 
   
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
    
 
   
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
    
 
   
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
    
 
   
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
    
 
   
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
    
 
   
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
    
 
   
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
    
 
   
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
    
 
   
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions with respect to
     the Common OP Units of $2.25 and the estimated 1998 distributions of $0
     with respect to your units, distributions with respect to the Preferred OP
     Units and Common OP Units to be received in the Offer are expected to be
     greater, immediately following the offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
    
 
   
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
    
 
   
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
    
 
   
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
    
 
                                      S-55
<PAGE>   61
 
   
properties although there are other ways to value real estate. A liquidation in
the future might generate a higher price for holders of units.
    
 
   
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
    
 
   
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
    
 
   
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
    
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
   
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
    
 
   
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
    
 
   
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   62
 
  Prices on Secondary Market
 
   
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. However,
we have made two prior tender offers for units. In the first offer, made in
August, 1997, we offered to acquire all units of your partnership at a price of
$2,648 per unit in cash. In June, 1998, we offered to acquire all units of your
partnership at a price of $21,668 per unit in cash.
    
 
   
  Estimated Liquidation Proceeds
    
 
   
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
    
 
   
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
    
 
ALLOCATION OF CONSIDERATION
 
   
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
    
 
                                STANGER ANALYSIS
 
   
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
    
 
   
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
    
 
   
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
    
 
   
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion --

     Assumptions, Limitations and Qualifications." We have agreed to indemnify
Stanger against certain liabilities arising out of Stanger's engagement to
prepare and deliver the Fairness Opinion.

     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and
through June 30, 1998; (v) reviewed operating budgets for your partnership's

also performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
    
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
   
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property manage-
    
 
                                      S-58
<PAGE>   64
 
   
     ment personnel were interviewed concerning your partnership's property and
local market conditions. Stanger also reviewed and relied upon information
provided by your partnership and AIMCO, including, but not limited to, financial
schedules of historical and current rental rates, occupancies, income, expenses,
reserve requirements, cash flow and related financial information; property
descriptive information including unit mix; and information relating to the
condition of the property, including any deferred maintenance, capital budgets,
status of ongoing or newly planned property additions, reconfigurations,
improvements and other factors affecting the physical condition of the property
improvements.
    
 
   
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
    
 
   
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
    
 
   
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
    
 
   
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
    
 
CONCLUSIONS
 
   
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
    
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
   
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical

     experience, are consistent with the terms of your partnership's agreement
of limited partnership, and reflect the best currently available estimates and
good faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
    
 
   
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
    
 
   
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
    
 
   
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
   
     The general partner of your partnership became a subsidiary of AIMCO in
June, 1997, when AIMCO acquired NHP. Accordingly, the general partner of your
partnership is an affiliate of the AIMCO Operating Partnership and, therefore,
has substantial conflicts of interest with respect to the offer. The general
partner of your partnership has a fiduciary obligation to obtain a fair offer
price for you, even as a subsidiary of AIMCO. It also has a duty to remove the
property manager for your partnership's property, under certain circumstances,
even though the property manager is also an affiliate of AIMCO. The conflicts of
interest include the fact that a decision to remove, for any reason, the general
partner of your partnership from its current position as a general partner of
your partnership would result in a decrease or elimination of the substantial
management fees paid to an affiliate of the general partner of your partnership
for managing your partnership's property. Additionally, we desire to purchase
units at a low price and you desire to sell units at a high price. The general
partner of your partnership makes no recommendation as to whether you should
tender or refrain from tendering your units. Such conflicts of interest in
connection with the offer and the operation of AIMCO differ from those conflicts
of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
    
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
   
     We own the general partner of your partnership and a 95% non-voting
interest in the manager of your partnership's property. The general partner of
your partnership receives a fee of $2,083 per month for its services as general
partner from your partnership and may receive reimbursement for expenses
generated in its capacity as general partner. The property manager received
management fees of $427,385 in 1996, $437,571 in 1997 and $215,708 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership's property.
    
 
COMPETITION AMONG PROPERTIES
 
   
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
    
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
   
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
    
 
FUTURE EXCHANGE OFFERS
 
   
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. We conducted two
prior tender offers for units of your partnership. In August, 1997 we acquired a
0.7576% interest in your partnership through the first tender offer. In June
1998, we acquired an additional 0.3788% interest in your partnership through the
second tender offer. Although we have no current plans to conduct future
exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for

GENERAL
 
   
     Casa Del Mar Associates Limited Partnership is a Florida limited
partnership which raised net proceeds of approximately $7,400,000 in 1988
through a private offering. The promoter for the private offering of your
partnership was Stephen A. Goldberg. NHP acquired your partnership in July 1996.
AIMCO acquired NHP in June, 1997. There are currently a total of 77 limited
partners of your partnership and a total of 99 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
    
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
   
     Your partnership was formed on August 26, 1988 for the purpose of owning
and operating an assisted living apartment property located in Boca Raton,
Florida, known as "Casa Del Mar." Your partnership's property consists of 214
apartment units. There are 141 one-bedroom apartments and 73 two-bedroom
apartments. Assisted living services are provided in 60 units and 154 units
provide independent living. The total rentable square footage of your
partnership's property is 168,832 square feet. Your partnership's property had
an average occupancy rate of approximately 96% in 1997 and 92% during the first
six months of 1998. The average annual rent per apartment unit is approximately
$35,520.
    
 
   
     Your partnership's property provides residents with a number of amenities
and services. Each apartment is equipped with a washer and dryer. There are
emergency pull cords in every apartment and there is a courtesy security patrol
from 5pm - 8am every day. Your partnership's property provides transportation to
doctor's appointments within a 5-mile radius of the property. Group bus trips to
banks, shopping, and entertainment activities take place on pre-announced
schedules. Meal service is available three times per day in addition to a
snack/sandwich shop. Five course dinners are offered nightly with fourteen
entree choices. Activities include billiards, fitness programs with a certified
trainer, movies, swimming pool, spa, movies, lectures and live entertainment in
the property's auditorium. Preferred Home Health, an affiliate of AIMCO, is a
home health care agency with an office on site.
    
 
PROPERTY MANAGEMENT
 
   
     Since 1997, your partnership's property has been managed by an entity which
is now an affiliate of AIMCO. Pursuant to the management agreement between the
property manager and your partnership, the property manager operates your
partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $427,385, $437,571 and $215,708, respectively.
    
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
   
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2038 unless earlier dissolved. Your
partnership has no present intention to liquidate, sell, finance or refinance
your partnership's property within any specified time period.
    
 
   
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.

     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
    
 
CAPITAL REPLACEMENT
 
   
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
    
 
BORROWING POLICIES
 
   
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $13,800,862, payable to Mellon Bank MD, which bears interest at
the rate of 8.12%. The mortgage debt is due in August 2005. In addition, your
partnership had borrowed $1,714,490 (including accrued interest) from an
unrelated party on an unsecured basis as of June 30, 1998. The majority of these
borrowings bear interest at 9% and are due July 2006. Your partnership's
agreement of limited partnership also allows the general partner of your
partnership to lend funds to your partnership. As of June 30, 1998, the general
partner of your partnership had outstanding loans (including accrued and unpaid
interest) of $5,906,796 to your partnership, which generally bear interest at a
rate of 9% and mature in July 2006.
    
 
COMPETITION
 
   
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
    
 
LEGAL PROCEEDINGS
 
   
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
    
 
  Overview
 
   
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited and unaudited financial statements included elsewhere herein.
    
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Loss
 
   
     Your partnership recognized net loss of $242,115 for the six months ended
June 30, 1998, compared to net loss of $89,887 for the six months ended June 30,
1997. The increased net loss of $152,228, or 169%, was primarily due to
decreased rental and other property revenues and increased operating expenses
and general administrative expenses discussed below.
    
 
     Revenues
 
   
     Rental and other property revenues of your partnership totaled $3,633,623
for the six months ended June 30, 1998, compared to $3,699,929 for the six
months ended June 30, 1997, a decrease of $66,306, or 2%. This decline was
related to higher vacancy rates during 1998 than 1997.
    
 
     Expenses
 
   
     Operating expenses of your partnership, consisting of utilities (net of
reimbursements received from tenants), contract services, payroll, turnover
costs, repairs and maintenance, advertising and marketing, property taxes,
insurance and health center expenses, totaled $2,156,586 for the six months
ended June 30, 1998, compared to $2,034,533 for the six months ended June 30,
1997, an increase of $122,053, or 6%. This increase was due to higher payroll
and related expenses, repairs and maintenance costs and advertising costs, which
were somewhat offset by reduced health center expenses, during 1998. 401(k)
eligibility requirements changed when AIMCO purchased the general partner and
the property manager from NHP in 1997. As a result, the number of eligible
employees increased resulting in higher payroll expenses. During 1998, a new
advertising agency was hired to develop a marketing strategy to improve
occupancy. 1998 repairs and maintenance increased over the prior period due to
repairs related to the kitchen located on the premises, as well as cost
associated with the turnover of vacant units. In March 1998, AIMCO contracted
with a new food service to provide a lower cost food service program. As a
result, health center expenses decreased in 1998 by $44,531. Your partnership's
management expenses totaled $215,708 for the six months ended June 30, 1998,
compared to $222,929 for the six months ended June 30, 1997, a decrease of
$7,221, or 3%. Management fees are based on 6% of collected revenues, which
decreased in 1998.
    
 
     General and Administrative Expenses
 
     General and administrative expenses decreased to $138,306 for the six
months ended June 30, 1998 from $177,149 for the six months ended June 30, 1997,
a decrease of $38,843, or 22%. This was primarily due to recruiting expense of
$27,117 incurred in 1997, but not in 1998.
 
     Interest Expense
 
     Interest expense totaled $905,975 for the six months ended June 30, 1998,
compared to $894,580 for the six months ended June 30, 1997, an increase of
$11,395 or 1%.

     Interest Income
 
     Interest income totaled $4,274 for the six months ended June 30, 1998,
compared to $2,643 for the six months ended June 30, 1997, an increase of $1,631
or 62%. This increase was related to interest income earned on operating funds.
 
     Comparison of the year ended December 31, 1997 to the year ended December
31, 1996
 
     Net Loss
 
     Your partnership recognized loss before extraordinary item of $352,461 for
the year ended December 31, 1997, compared to loss before extraordinary item of
$748,950 for the year ended December 31, 1996. The decrease in loss before
extraordinary item of $396,489, or 53%, was primarily due to increased rental
and other property revenues in 1997. Your partnership recognized net loss of
$352,461 for the year December 31, 1997, compared to net loss of $398,693 for
the year ended December 31, 1996, a decrease in net loss of $46,232, or 12%. The
reasons for these variances are discussed below.
 
     Revenues
 
     Rental and other property revenues of your partnership totaled $7,329,537
for the year ended December 31, 1997, compared to $6,961,529 for the year ended
December 31, 1996, an increase of $368,008, or 5%. This increase was primarily a
result of an increase in 1997 average rental rates.
 
     Expenses
 
     Operating expenses of your partnership, consisting of, utilities (net of
reimbursement received from tenants), contract services, payroll, turnover
costs, repairs and maintenance, advertising and marketing, property taxes,
insurance and health center expenses, totaled $4,264,030 for the year ended
December 31, 1997, compared to $4,112,001 for the year ended December 31, 1996,
an increase of $152,029, or 4%. 401(k) eligibility requirements changed when NHP
purchased the general partner of your partnership and assumed management of your
partnership in July 1996. As a result, the number of eligible employees
increased resulting in increased payroll expenses of $57,017. An accelerated
marketing strategy was implemented to reduce vacancies in late 1997, resulting
in an increase in advertising expenses of $103,366. Management expenses totaled
$437,571 for the year December 31, 1997, compared to $427,385 for the year ended
December 31, 1996, an increase of $10,186, or 2%. Depreciation and amortization
totaled $930,683 in 1997 compared to $1,078,157 in 1996, a decrease of $147,474
or 14%. This decrease in depreciation and amortization was due to numerous
assets becoming fully depreciated during 1997.
 
     General and Administrative Expenses
 
     General and administrative expenses increased to $293,600 for the year
ended December 31, 1997 from $270,143 for the year ended December 31, 1996, an
increase of $23,457, or 9%. This was due primarily to recruiting expense of
$27,117 incurred in 1997, but not in 1996.
 
     Interest Expense
 
     Interest expense totaled $1,762,404 for the year ended December 31, 1997,
compared to $1,824,452 for the year ended December 31, 1996, a decrease of
$62,048 or 3%. This decrease in interest expense was due to the forgiveness of
debt of $452,369 and the reduction of the interest rates charged on your
partnership's notes payable to related parties and notes payable to others from
13% to 9% per annum.
 
     Interest Income
 
     Interest income totaled $6,290 for the year ended December 31, 1997,
compared to $1,659 for the year ended December 31, 1996, an increase of $4,631,
or 279%. This increase is related to interest earned on operating funds.

Liquidity and Capital Resources
 
   
     Your partnership has periodically required loans from the partners to cover
cash flow deficiencies; however, the partners are not obligated to provide
additional funds to cover further cash flow deficiencies. Accordingly, your
partnership's ability to continue operating in its present form is dependent
upon its ability to generate sufficient cash flow from operations to fund
necessary capital improvements, debt service and other cash flow needs that may
arise or to arrange for further loans from partners or other sources.
    
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
   
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Your partnership's agreement of
limited partnership provides that neither the general partner of your
partnership nor any of its affiliates performing services on behalf of your
partnership will be liable to your partnership or any of the offerees for any
act or omission by any such person if such person, in good faith, determined
that such course of conduct was in the best interests of your partnership,
provided that such act or omission did not constitute misconduct or negligence
on the part of such person. As a result, offerees might have a more limited
right of action in certain circumstances than they would have in the absence of
such a provision in your partnership's agreement of limited partnership. The
general partner of your partnership is owned by AIMCO. See "Conflicts of
Interest".
    
 
   
     Your Partnership Agreement also provides that the general partner of your
partnership and certain related parties are indemnified from losses, judgments,
liabilities, expenses and amounts paid in settlement of any claims sustained by
them in connection with your partnership (except to the extent indemnification
is prohibited by law) provided that the course of conduct did not constitute
negligence or misconduct on the part of the general partner or its affiliates.
Notwithstanding the foregoing, none of the above-mentioned persons is to be
indemnified by your partnership from liability, loss, damage, cost or expense
incurred by him in connection with any claim involving allegations that such
person violated Federal or state securities laws unless (a) there has been a
successful adjudication on the merits of the claims of each count involving
alleged securities law violations as to the person seeking indemnification, (b)
such claims have been dismissed with prejudice on the merits by a court of
competent jurisdiction, or (c) a court of competent jurisdiction has approved a
settlement of the claims against the person seeking indemnification. In each of
the foregoing situations, the court of law considering the request for
indemnification must be advised as to the position of the SEC and any other
applicable regulatory authority regarding indemnification for violations of
securities laws. Indemnification may not be enforceable as to certain
liabilities arising from claims under the Securities Act of 1933, as amended and
the rules and regulations promulgated thereunder and state securities laws; and,
in the opinion of the SEC, such indemnification is contrary to the public policy
and is therefore unenforceable. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
    
 
   
     Your partnership does not pay for any insurance, other than public
liability insurance, covering liability of the general partner of your
partnership or any other indemnified person for acts or omissions for which
indemnification is not permitted by your partnership's Agreement.
    
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
   
     Your partnership has not made any distributions in the past five years. The
original cost per unit was $74,000.
    
 
  Transfers
 
   
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the
    
 
                                      S-77
<PAGE>   83
 
   
admission of the transferee as a substitute limited partner in your partnership
require the consent of the general partner of your partnership under your
partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner) was as follows:

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
    
 
   
     In August, 1997 we acquired 0.7576% interest in your partnership through a
prior tender offer. In June 1998, we acquired an additional 0.3788% interest in
your partnership through another tender offer. Other than the units owned as a
result of these prior tender offers, neither the AIMCO Operating Partnership,
nor, to the best of its knowledge, any of its affiliates, (i) beneficially own
or have a right to acquire any units, (ii) have effected any transaction in the
units, or (iii) have any contract, arrangement, understanding or relationship
with any other person with respect to any securities of your partnership,
including, but not limited to, contracts, arrangements, understandings or
relationships concerning transfer or voting thereof, joint ventures, loan or
option arrangements, puts or calls, guarantees of loans, guarantees against loss
or the giving or withholding of proxies.
    
 
   
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
    
 
   
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

partnership. Your partnership has historically paid the property management fees
as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
   
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners
Casa Del Mar Associates Limited Partnership
 
     We have audited the accompanying balance sheet of Casa Del Mar Associates
Limited Partnership, a limited partnership, as of December 31, 1997, and the
related statements of operations, partners' capital deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Casa Del Mar Associates
Limited Partnership at December 31, 1997, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.
 
     As discussed in Note 3 to the financial statements, the Partnership's
recurring deficiencies in cash flow raise substantial doubt about its ability to
continue as a going concern. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                  CASA DEL MAR ASSOCIATES LIMITED PARTNERSHIP
 
                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE 1 -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     Casa Del Mar Associates Limited Partnership (the "Partnership") was formed
as a limited partnership under the laws of the state of Florida on August 26,
1988, to own and operate a senior living community consisting of a 154 unit
retirement center of individual apartments and a 60 unit personal care facility
for individuals requiring some additional assistance with the activities of
daily living. The community is known as Casa Del Mar located in Palm Beach
County, Florida.
 
     Allocations of cash distributions and net income and losses are made in
accordance with the Partnership Agreement.
 
     Real estate is recorded on the basis of cost and represents collateral for
the mortgage note payable. Depreciation is computed generally by the
straight-line method over the estimated useful lives of the related assets.
 
     Cash equivalents are defined as short-term, highly liquid investments with
original maturities of three months or less. The affiliated management company
maintains cash concentration accounts on behalf of affiliated entities which are
included in cash and cash equivalents.
 
     Deferred costs consist primarily of financing fees which are amortized over
the related term of the note.
 
     No provision has been made for income taxes or related credits, as the
results of operations are includable in the tax returns of the partners.
 
     Preparation of financial statements requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
     The accompanying unaudited financial statements of the Partnership as of
June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that accounting measurements at interim dates inherently
involve greater reliance on estimates than at year-end. The results of
operations for the interim periods presented are not necessarily indicative of
the results for the entire year.

     Partners' capital deficit as of January 1, 1997 has been restated for the

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Partners of
Casa Del Mar Associates Limited Partnership:
 
     We have audited the accompanying balance sheet of Casa Del Mar Associates
Limited Partnership (a Florida limited partnership, the "Partnership"), as of
December 31, 1996, and the related statements of operations, changes in
partners' deficit, and cash flows for the year then ended. These financial
statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As indicated in Note 8, the Partnership has experienced deficiencies in
cash flow and has required funding from its partners in the year ended December
31, 1997 and the six months ended June 30, 1998. Continuation of the
Partnership's operations in the present form is dependent on its ability to
achieve cash flow, additional funding from partners, or funding from other
sources.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Casa Del Mar Associates
Limited Partnership as of December 31, 1996, and the results of its operations
and its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
    
                            AS OF DECEMBER 31, 1996
 
1. THE PARTNERSHIP:
 
     Casa Del Mar Associates Limited Partnership (the "Partnership") was
organized as of August 26, 1988 pursuant to the laws of the state of Florida,
and according to the Agreement of Limited Partnership (the "Partnership
Agreement"), shall continue until December 31, 2038, unless sooner dissolved in
accordance with the Partnership Agreement.
 
     The Partnership operates a senior living community consisting of 214
apartment units in Palm Beach County, Florida (the "Facility"). The Facility
consists of two self-contained buildings. The first building is a 154-unit
retirement center consisting of a central amenity building and two wings of
individual apartments. The second building is a 60-unit personal care facility,
for those individuals requiring some additional assistance with the activities
of daily living.
 
     On July 12, 1996, a controlling interest in the Partnership's general
partner was acquired by NHP Real Estate Corporation, an affiliate of NHP
Incorporated (see Note 7).
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
     The Partnership considers all highly liquid investments with initial
maturities of 90 days or less to be cash equivalents.
 
     NHP Management Company ("NHPMC"), a wholly owned subsidiary of NHP
Incorporated, assumed property management responsibility for the Facility as
part of the purchase effective July 12, 1996. NHPMC maintains at banks
concentrated cash and cash equivalent accounts of affiliated entities for which
it provides property management services. As of December 31, 1996, NHPMC did not
hold any cash on behalf of the Partnership.
 
RENTAL REVENUE
 
     Property owned by the Partnership is subject to numerous tenant leasing
arrangement having initial terms of one year or less. Rental revenue from these
arrangements is recognized on a straight line basis over the appropriate lease
term.
 
DEPRECIATION
 
     Depreciation of the land improvements and building and improvements are
computed using the straight line method, assuming a 15 year and 27.5 year life,
respectively. Furniture, fixtures and equipment are depreciated using an
accelerated method, assuming an estimated useful life of 5 to 7 years.

                  CASA DEL MAR ASSOCIATES LIMITED PARTNERSHIP
 
   
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
AMORTIZATION
 
     Deferred finance costs are amortized over the appropriate mortgage loan
period using the straight-line method, which approximates the effective interest
method. The related amortization is recorded within interest expense in the
accompanying statement of operations.
 
INCOME TAXES
 
     The Partnership is not a tax paying entity and, accordingly, no provision
has been recorded for Federal or state income tax purposes. The partners are
individually responsible for reporting their share of the Partnership's taxable
income on their income tax returns. In the event of an examination of the
Partnership's tax return by the Internal Revenue Service, the tax liability of
the partners could be changed if an adjustment in the Partnership's income is
ultimately sustained by the taxing authorities.
 
     Certain transactions of the Partnership may be subject to accounting
methods for income tax purposes that differ from the accounting methods used in
preparing these financial statements in accordance with generally accepted
accounting principles. Accordingly, the net income or loss of the Partnership
and the resulting balances in the partners' capital accounts reported for income
tax purposes may differ from the balances reported for those same items in these
financial statements.
 
IMPLEMENTATION OF NEW ACCOUNTING STANDARD
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of
Long-Lived Assets and Assets to be Disposed Of," which the Partnership
implemented on January 1, 1996. The adoption of this statement did not have an
effect on the Partnership's financial position or results of operations.
 
3. PARTNERSHIP PROFITS AND LOSSES AND DISTRIBUTIONS:
 
     Net income of the Partnership is allocated to the partners, pro rata, based
on any negative capital account balances, until such negative capital balances
are eliminated; any remaining income is allocated to the partners, pro rata,
based on their respective percentage interests. Net losses are allocated to the
partners, pro rata, based on any positive capital balances, until such positive
capital balances are eliminated. Any remaining losses are allocated to the
partners, pro rata, based on their respective percentage interests. Net cash
flow is to be distributed, pro rata to the Preferred Limited Partners, until
each Preferred Limited Partner has received distributions equal to a cumulative,
simple 12% annual return on his net cash investment, as defined in the
Partnership Agreement. Any remaining net cash flow will be distributed in
accordance with the percentage interests.
 
4. MORTGAGE NOTES PAYABLE:
 
     The Partnership is indebted to Washington Capital DUS, Inc. for a first
mortgage note payable (the "First Mortgage Note") in the original amount of
$14,365,000 issued in September 1995. As of December 31, 1996, the First
Mortgage Note had an outstanding balance of $14,120,604. The First Mortgage note
is payable in monthly principal and interest payments of $112,016, with an
interest rate of 8.12% per annum until

</TABLE>
 
     In connection with the issuance of the First Mortgage Note, the Partnership
capitalized deferred finance costs of $338,980, which is shown net of
accumulated amortization of $33,898 as of December 31, 1996.
 
     The First Mortgage Note is secured by the buildings and improvements, as
well as other amounts deposited with the lender.
 
5. ADVANCES FROM AFFILIATE:
 
     Prior to July 12, 1996, the Partnership had been advanced funds from the
general partner. These advances bore interest at 9 percent per annum and were to
become due on December 31, 2002. In connection with the sale of the general
partner interest described in Note 1, any previously accrued and unpaid interest
was added to the principal balance, and the note was assigned to NHP
Incorporated. In addition, $102,112 in principal and accrued interest was
forgiven, resulting in a newly stated outstanding balance of $5,108,000. The
gain on forgiveness of debt is reflected as a capital contribution in the
accompanying statement of changes in partners' deficit. The new advance bears
interest at 9.75 percent per annum, with amounts payable monthly from net cash
flow, as defined in the note agreement. All unpaid principal and interest are
due and payable on July 12, 2006.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
6. NOTES PAYABLE:
 
     Prior to July 12, 1996, the Partnership was liable to Casa Del Mar
Participation Corporation, an affiliate of the Partnership, for a note payable
in the original amount of $2,000,000. This note bore interest at a rate of 13
percent, with variable monthly principal and interest payments, until September
1, 2002, when all unpaid amounts were to become due and payable. In connection
with the sale of the general partner interest described in Note 1, this note
payable was restructured such that any previously accrued and unpaid interest
was added to the principal balance and was assigned to Stephen A. Goldberg. In
addition, $350,257 in principal and accrued interest was forgiven, resulting in
newly stated principal balance of $1,428,000. This gain on forgiveness of debt
is reflected as an extraordinary item on the statement of operations. The new
note payable bears interest at 9.00 percent per annum, with amounts payable
monthly from net cash flow, as defined in the loan agreement. All unpaid
principal and interest are due and payable in July 2006.
 
     In addition, as of December 31, 1996, the Partnership was liable for two
notes payable, in the aggregate amount of $56,503, issued for the purpose of
acquiring business equipment. The loans accrued interest at 13.87 percent and
11.54 percent annually, with combined monthly payments of $2,668 and maturities
of October and November 1999, respectively.
 
7. RELATED-PARTY TRANSACTIONS:
 
     NHPMC is the project management agent under an agreement which extends,
subject to certain conditions, to the year 2020. Certain stockholders owning
approximately 60 percent of the voting stock of NHP Incorporated also control
the entity which holds the general partnership interest in the Partnership.
 
     During 1996, personnel working at the Facility were employees of NHP
Incorporated, and therefore the Facility reimbursed NHP Incorporated for the
actual salaries and related benefits, as reflected in the accompanying financial
statements. At December 31, 1996, trade payables include $196 due to NHP
Incorporated.
 
     During 1996, NHPMC received a fee of $106,187 for its services as
management agent for the period from July 12, 1996 through December 31, 1996. As
part of the management agreement, management fees are calculated as 6 percent of
the Facility's rental collections, with 4 percent paid currently, and the
remaining 2 percent deferred until January of the following year. As of December
31, 1996, $142,462 of deferred management fees is included in accrued management
fee on the accompanying balance sheet.
 
8. SUBSEQUENT EVENT:
 
     The Partnership has experienced deficiencies in cash flow and has required
funding from its partners in the year ended December 31, 1997 and the six months
ended June 30, 1998. Continuation of the Partnership's operations in the present
form is dependent on its ability to achieve cash flow, additional funding from
partners, or funding from other sources.

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
                                       A-1
<PAGE>   104
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   105
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

     SEE "RISK FACTORS" BEGINNING ON PAGE 2 FOR A DISCUSSION OF MATERIAL RISKS
IN CONNECTION WITH AN INVESTMENT IN THE SECURITIES, INCLUDING WITHOUT
LIMITATION, THE FOLLOWING RISKS:
    
 
     - Our acquisition and development activities expose us to several negative
       factors, including difficulty in managing our rapid growth, the
       incurrence of unforeseen costs, possible failure to realize projected
       occupancy and rental rates.
 
     - Our organizational documents do not limit the amount of debt that we may
       incur, and our Board of Directors may change our leverage policy at any
       time. Our cash flow from operations might be insufficient to make
       required debt payments, and we might be unable to refinance our debt at
       all or on terms as favorable as the terms of our existing debt. In
       addition, we are subject to debt covenants that may restrict our ability
       to make distributions to investors.
 
     - Our real estate investment and management activities expose us to several
       potentially negative factors that are beyond our control such as local
       economic conditions, intense competition, potential environmental
       liabilities and change of laws, any of which could negatively affect our
       financial condition or results of operations.
 
     - We and certain of our officers and/or directors and unconsolidated
       subsidiaries have entered into, and may in the future into certain
       transactions that may result in conflicts of interest between the us and
       such officers and/or directors and unconsolidated subsidiaries.
 
     - If Apartment Investment and Management Company fails to qualify as a
       REIT, it (i) would not be allowed a deduction for dividends it pays, (ii)
       would be subject to federal income tax at corporate rates, (iii) might
       need to borrow funds or liquidate investments on unfavorable terms in
       order to pay the applicable tax and (iv) would no longer be required to
       make distributions to stockholders.
 
     - Our charter limits the number of shares of our stock that may be held by
       any one investor. Consequently, our stockholders are limited in their
       ability to effect a change of our control.
 
     - Investors in our partnership units must hold their units for one year,
       subject to certain exceptions. Thereafter investors may transfer such
       partnership units, subject to the satisfaction of certain conditions,
       including the general partner's right of first refusal. Holders of our
       partnership units do not have the ability to vote for or remove the
       general partner, and therefor they can not effect a change of control of
       AIMCO Properties, L.P.
 
     To the extent not otherwise described herein, the form in which the
securities are to be issued, and the terms of such securities, including without
limitation, their specific designation, or aggregate initial offering price,
rate and times of payment of dividends, if any, redemption, conversion and
exchange terms, if any, voting or other rights, if any, and other specific terms
will be set forth in a Prospectus Supplement, together with the terms of
offering of such securities.
 
     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ADEQUACY OR ACCURACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
 
     THE ATTORNEY GENERAL OF THE STATE OF NEW YORK HAS NOT PASSED ON OR ENDORSED
THE MERITS OF THIS OFFERING. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

                                  THE COMPANY
 
   
     Apartment Investment and Management Company ("AIMCO"), a Maryland
corporation formed on January 10, 1994, is a self-administered and self-managed
REIT engaged in the ownership, acquisition, development, expansion and
management of multi-family apartment properties. As of October 1, 1998, we owned
or managed 396,090 apartment units in 2,303 properties located in 49 states, the
District of Columbia and Puerto Rico. Based on apartment unit data compiled as
of January 1, 1998 by the National Multi Housing Council, we believe that, as of
October 1, 1998, we were the largest owner and manager of multifamily apartment
properties in the United States. As of October 1, 1998, we:
    
 
   
     - owned or controlled 58,495 units in 209 apartment properties;
    
 
   
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
    
 
   
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
    
 
   
     We conduct substantially all of our operations through AIMCO Properties,
L.P., a Delaware limited partnership (the "AIMCO Operating Partnership"). Our
wholly owned subsidiary, AIMCO-GP, Inc. (the "AIMCO GP") is the sole general
partner of the AIMCO Operating Partnership. Through the AIMCO GP and another of
our wholly owned subsidiaries, AIMCO-LP, Inc. (the "Special Limited Partner"),
as of October 1, 1998, we owned approximately an 89% interest in the AIMCO
Operating Partnership. We manage apartment properties for third parties and
affiliates through unconsolidated subsidiaries that we refer to as the
"management companies." Generally, when we refer to "we," "us" or the "Company"
in this prospectus, we are referring to AIMCO, the AIMCO Operating Partnership,
the management companies and their respective subsidiaries.
    
 
   
     Our principal executive offices are located at 1873 South Bellaire Street,
17th Floor, Denver, Colorado 80222, and our telephone number is (303) 757-8101.

                                  RISK FACTORS
 
     Before you invest in our securities, you should be aware that there are
various risks, including those described below. You should consider carefully
these risk factors together with all of the other information included in this
prospectus before you decide to purchase our securities.
 
     Some of the information in this prospectus may contain forward-looking
statements. Such statements can be identified by the use of forward-looking
terminology such as "may," "will," "expect," "anticipate," "estimate,"
"continue" or other similar words. These statements discuss future expectations,
contain projections of results of operations or of financial condition or state
other "forward-looking" information. When considering such forward-looking
statements, you should keep in mind the risk factors and other cautionary
statements in this prospectus. The risk factors noted in this section and other
factors noted throughout this prospectus, including certain risks and
uncertainties, could cause our actual results to differ materially from those
contained in any forward-looking statement.
 
RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES
 
   
     Generally. The selective acquisition, development and expansion of
apartment properties is one component of our growth strategy. However, we can
make no assurance as to our ability to identify or complete transactions in the
future. Although we seek to acquire, develop and expand properties only when
such activities are accretive on a per share basis, such transactions may fail
to perform in accordance with our expectations. When we develop or expand
properties, we are subject to the risks that:
    
 
     - costs may exceed original estimates;
 
     - projected occupancy and rental rates at the property may not be realized;
 
     - financing may not be available on favorable terms;
 
   
     - construction and lease-up may not be completed on schedule; and
    
 
     - we may experience difficulty or delays in obtaining necessary zoning,
       land-use, building, occupancy, and other governmental permits and
       authorizations.
 
   
     We May Have Difficulty Managing Our Rapid Growth. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned or managed properties
from 132 apartment properties with 29,343 units to 2,303 apartment properties
with 396,090 units as of October 1, 1998. These acquisitions have included
purchases of properties and interests in entities that own or manage properties,
as well as corporate mergers. Our recent merger with Insignia Financial Group,
Inc. ("Insignia") is our largest acquisition so far. Our ability to successfully
integrate acquired businesses and properties depends on our ability to:
    
 
     - attract and retain qualified personnel;
 
   
     - integrate the personnel and operations of the acquired businesses;
    
 
     - maintain uniform standards, controls, procedures and policies; and
 
     - maintain adequate accounting and information systems.
 
   
     We can provide no assurance that we will be able to accomplish these goals
and successfully integrate any acquired businesses or properties. If we fail to
successfully integrate such businesses, our results of operations could be
adversely affected.
    
 
     Litigation Associated with Partnership Acquisitions. We have engaged in,
and intend to continue to engage in, the selective acquisition of interests in
limited partnerships that own apartment properties. In some cases, we have
acquired the general partner of a partnership and then made an offer to acquire
the limited partners' interests in the partnership. In these transactions, we
are subject to litigation based on claims that the general partner has breached
its fiduciary duties to its limited partners or that the transaction violates
the
 
                                        2
<PAGE>   111
 
   
relevant partnership agreement. Although we intend to comply with our fiduciary
obligations and relevant partnership agreements, we may incur additional costs
in connection with the defense or settlement of such litigation. In some cases,
such litigation may adversely affect our desire to proceed with, or our ability
to complete, a particular transaction. Such litigation could also have a
material adverse effect on our results of operations.
    
 
RISKS ASSOCIATED WITH DEBT FINANCING
 
   
     Our strategy is generally to incur debt to increase the return on our
equity while maintaining acceptable interest coverage ratios. We seek to
maintain a ratio of free cash flow to combined interest expense and preferred
stock dividends of between 2:1 and 3:1. However, our Board of Directors could
change this strategy at any time and increase our leverage. Our organizational
documents do not limit the amount of debt that we may incur, and we have
significant amounts of debt outstanding. Payments of principal and interest may
leave us with insufficient cash resources to operate our properties or pay
distributions required to be paid in order to maintain our qualification as a
REIT. We are also subject to the risk that our cash flow from operations will be
insufficient to make required payments of principal and interest, and the risk
that existing indebtedness may not be refinanced or that the terms of any
refinancing will not be as favorable as the terms of existing indebtedness. If
we fail to make required payments of principal and interest on any debt, our
lenders could foreclose on the properties securing such debt with a consequent
loss of income and asset value to us. As of June 30, 1998, 94% of the properties
that we own or control and 43% of our assets were encumbered by debt. On a pro
forma basis, giving effect to the recent Insignia merger, as of June 30, 1998,
we had $1,626 million of indebtedness outstanding on a consolidated basis, of
which $1,604 million was secured.
    
 
INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE
 
   
     As of June 30, 1998, approximately $182 million of our debt was subject to
variable interest rates. An increase in interest rates could increase our
interest expense and adversely affect our cash flow and our ability to service
our indebtedness and make distributions.
    
 
RISKS OF INTEREST RATE HEDGING ARRANGEMENTS
 
     From time to time, in anticipation of refinancing debt, we enter into
agreements to reduce the risks associated with increases in short term interest
rates. Although these agreements provide us with some protection against rising
interest rates, these agreements also reduce the benefits to us when interest
rates decline. These agreements involve the following risks:
 
     - interest rate movements during the term of the agreement may result in a
       gain or loss to us;
 
     - we may be exposed to losses if the hedge is not indexed to the same rate
       as the debt anticipated to be incurred; and
 
     - if the counterparty to the agreement fails to pay, we may incur a loss.
 
COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR INVESTORS
 
   
     Some of our debt and other securities contain covenants that restrict our
ability to make distributions or other payments to our investors unless certain
financial tests or other criteria are satisfied. In some cases, our subsidiaries
are subject to similar provisions, which may restrict their ability to make
distributions to us. Our primary credit facility provides that we may make
distributions to our investors during any 12-month period in an aggregate amount
that does not exceed the greater of 80% of our funds from operations for such
period or such amount as may be necessary to maintain our REIT status. This
credit facility prohibits all distributions if certain financial ratios and
tests are not satisfied. The preferred stock that we issued in the Insignia
merger prohibits the payment of dividends on our common stock if we fail to make
the payments required by the preferred stock.
    
 
                                        3
<PAGE>   112
 
WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES
 
   
     All of our properties are owned, and all of our operations are conducted,
by the AIMCO Operating Partnership and our other subsidiaries. As a result, we
depend on distributions and other payments from subsidiaries in order to satisfy
our financial obligations and make payments to our investors. The ability of our
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations. As an
equity investor in our subsidiaries, our right to receive assets upon their
liquidation or reorganization will be effectively subordinated to the claims of
their creditors. To the extent that we are recognized as a creditor of such
subsidiaries, our claims would still be subordinated to any security interest in
or other lien on their assets and to any of their debt or other obligations that
are senior to us.
    
 
REAL ESTATE INVESTMENT RISKS
 
     Our ability to make payments to our investors depends on our ability to
generate funds from operations in excess of required debt payments and capital
expenditure requirements. Funds from operations and the value of our properties
may be adversely affected by events or conditions which are beyond our control.
Such events or conditions could include:
 
     - the general economic climate;
 
     - competition from other apartment communities and alternative housing;
 
     - local conditions, such as an increase in unemployment or an oversupply of
       apartments, that might adversely affect apartment occupancy or rental
       rates;
 
     - increases in operating costs (including real estate taxes) due to
       inflation and other factors, which may not necessarily be offset by
       increased rents;
 
     - changes in governmental regulations and the related costs of compliance;
 
     - changes in tax laws and housing laws, including the enactment of rent
       control laws or other laws regulating multifamily housing;
 
     - changes in interest rate levels and the availability of financing; and
 
     - the relative illiquidity of real estate investments.
 
POSSIBLE ENVIRONMENTAL LIABILITIES
 
     Various Federal, state and local laws subject property owners or operators
to liability for the costs of removal or remediation of certain hazardous
substances released on a property. Such laws often impose liability without
regard to whether the owner or operator knew of, or was responsible for, the
release of the hazardous substances. The presence of, or the failure to properly
remediate, hazardous substances may adversely affect occupancy at contaminated
apartment communities and our ability to sell or borrow against contaminated
properties. In addition to the costs associated with investigation and
remediation actions brought by governmental agencies, the presence of hazardous
wastes on a property could result in personal injury or similar claims by
private plaintiffs. Various laws also impose, on persons who arrange for the
disposal or treatment of hazardous or toxic substances, liability for the cost
of removal or remediation of hazardous substances at the disposal or treatment
facility. These laws often impose liability whether or not the person arranging
for the disposal ever owned or operated the disposal facility.
 
LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED EXPENSES
 
     Under the Americans with Disabilities Act of 1990 (the "ADA"), all places
of public accommodation are required to meet certain Federal requirements
related to access and use by disabled persons. These requirements became
effective in 1992. A number of additional Federal, state and local laws exist
which also may require modifications to our properties, or restrict certain
further renovations of the properties, with respect to access thereto by
disabled persons. For example, the Fair Housing Amendments Act of 1988 (the
 
                                        4
<PAGE>   113
 
"FHAA") requires apartment properties first occupied after March 13, 1990 to be
accessible to the handicapped. Noncompliance with the ADA or the FHAA could
result in the imposition of fines or an award of damages to private litigants
and also could result in an order to correct any non-complying feature, which
could result in substantial capital expenditures. Although we believe that our
properties are substantially in compliance with present requirements, we may
incur unanticipated expenses to comply with the ADA and FHAA.
 
RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING
 
   
     As of October 1, 1998, we owned or controlled 2 properties, held an equity
interest in 783 properties and managed for third parties and affiliates 322
properties that benefit from governmental programs intended to provide housing
to people with low or moderate incomes. These programs, which are usually
administered by the United States Department of Housing and Urban Development
("HUD") or state housing finance agencies, typically provide mortgage insurance,
favorable financing terms or rental assistance payments to the property owners.
As a condition to the receipt of assistance under these programs, the properties
must comply with various requirements, which typically limit rents to
pre-approved amounts. If permitted rents on a property are insufficient to cover
costs, a sale of the property may become necessary, which could result in a loss
of management fee revenue. We usually need to obtain the approval of HUD in
order to manage, or acquire a significant interest in, a HUD-assisted or
HUD-insured property. We can make no assurance that we will always receive such
approval.
    
 
THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES
 
   
     We manage some properties owned by third parties. For the year ended
December 31, 1997, we derived approximately 2% of our gross revenue from
management of properties owned by third parties. During the same period,
Insignia, which merged with us on October 1, 1998, derived approximately 15% of
its gross revenue from management of properties owned by third parties. We may
suffer a loss of revenue if we lose our right to manage these properties or if
the rental revenues upon which our management fees are based declines. In
general, management contracts may be terminated or otherwise lost as a result
of:
    
 
     - a disposition of the property by the owner in the ordinary course or as a
       result of financial distress of the property owner;
 
     - the property owner's determination that our management of the property is
       unsatisfactory;
 
     - willful misconduct, gross negligence or other conduct that constitutes
       grounds for termination; or
 
     - with respect to certain affordable properties, termination of such
       contracts by HUD or state housing finance agencies, generally at their
       discretion.
 
DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS
 
   
     Although we have entered into employment agreements with our Chairman and
Chief Executive Officer, Terry Considine, our President, Peter K. Kompaniez and
our Executive Vice President, Steven D. Ira, the loss of any of their services
could have an adverse effect on our operations.
    
 
POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES
 
   
     We have been, and continue to be, involved in various transactions with a
number of our affiliates, including executive officers, directors and entities
in which they own interests. For example, in order to satisfy certain REIT
requirements, Messrs. Considine and Kompaniez directly or indirectly control the
management companies which manage properties for third parties and affiliates.
Although we own a 95% non-voting interest in these management companies, we have
no control over them or their operations. As a result, the management companies
could implement business decisions or policies that are not in our best
interests. We have adopted certain policies designed to minimize or eliminate
the conflicts of interest inherent in these transactions, including a
requirement that a majority of our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the
    
 
                                        5
<PAGE>   114
 
influence of such conflicts. Furthermore, such policies are subject to change
without the approval of our stockholders.
 
TAX RISKS
 
   
     Adverse Consequences of Failure to Qualify as a REIT. Although we believe
that we operate in a manner that enables us to meet the requirements for
qualification as a REIT for Federal income tax purposes, we do not plan to
request a ruling from the IRS that we qualify as a REIT. We have, however,
received an opinion from the law firm of Skadden, Arps, Slate, Meagher & Flom
LLP to the effect that, beginning with our initial taxable year ended December
31, 1994, we were organized in conformity with the requirements for
qualification as a REIT under the Internal Revenue Code.
    
 
   
     You should be aware that opinions of counsel are not binding on the IRS or
any court. Our opinion of counsel is based upon certain representations and
covenants made by us regarding the past, present and future conduct of our
business operations. Furthermore, our opinion of counsel is conditioned on, and
our continued qualification as a REIT will depend on, our ability to meet,
through actual annual operating results, the various REIT qualification tests.
Such requirements are discussed in more detail under the heading "Federal Income
Taxation of AIMCO and AIMCO Stockholders -- General."
    
 
   
     If we fail to qualify as a REIT, we would not be allowed a deduction for
distributions to shareholders in computing our taxable income and we would be
subject to Federal income tax at regular corporate rates. We also could be
subject to the Federal alternative minimum tax. Unless we are entitled to relief
under the tax law, we could not elect to be taxed as a REIT for four years
following the year during which we were disqualified. Therefore, if we lose our
REIT status, the funds available for payment to our investors would be reduced
substantially for each of the years involved. See "Federal Income Taxation of
AIMCO and AIMCO Stockholders -- General -- Failure to Qualify." Also, if we fail
to qualify as a REIT, (i) we would be obligated to repurchase 750,000 shares of
our preferred stock at a price of $105 per share, plus accrued and unpaid
dividends to the date of repurchase, and (ii) we would be in default under our
primary credit facilities and certain other loan documents. See "Federal Income
Taxation of AIMCO and AIMCO Stockholders -- Failure to Qualify."
    
 
   
     For example, we will qualify as a REIT only if, as of the close of any year
in which we acquire a corporation that is a C Corporation (a corporation that
does not qualify for taxation as a REIT, such as Insignia), we have no "earnings
and profits" acquired from such C Corporation. In the Insignia merger, we
succeeded to the earnings and profits of Insignia and, therefore, must
distribute such earnings and profits effective on or before December 31, 1998.
Insignia has retained independent certified public accountants to determine
Insignia's earnings and profits through the effective time of the Insignia
merger for purposes of this requirement. The determination of the independent
certified public accountants will be based upon Insignia's tax returns as filed
with the IRS and other assumptions and qualifications set forth in the reports
issued by such accountants. Any adjustments to Insignia's income for taxable
years ending on or before the closing of the Insignia merger, including as a
result of an examination of its returns by the IRS and the receipt of certain
indemnity or other payments could affect the calculation of Insignia's earnings
and profits. Furthermore, the determination of earnings and profits requires the
resolution of certain technical tax issues with respect to which there is no
authority directly on point and, consequently, the proper treatment of these
issues for earnings and profits purposes is not free from doubt. There can be no
assurance that the IRS will not examine the tax returns of Insignia and propose
adjustments to increase its taxable income and therefore its earnings and
profits. In this regard, the IRS can consider all taxable years of Insignia as
open for review for purposes of determining the amount of such earnings and
profits. Additionally, if the $50 million dividend required to be paid on the
AIMCO preferred stock issued in the Insignia merger is not treated as a dividend
under the Internal Revenue Code, we may, depending upon the amount of other
distributions made by us subsequent to the Insignia merger, fail to distribute
an amount equal to Insignia's earnings and profits. Our failure to distribute an
amount equal to such earnings and profits effective on or before December 31,
1998, would result in our failure to qualify as a REIT.
    
 
                                        6
<PAGE>   115
 
     Effect of Distribution Requirements. As a REIT, we are subject to annual
distribution requirements, which limit the amount of cash we have available for
other business purposes, including amounts to fund our growth. See "Federal
Income Taxation of AIMCO and AIMCO Stockholders -- Annual Distribution
Requirements."
 
   
     Possible Legislative or Other Actions Affecting REITs. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the tax law could adversely affect our investors. It cannot be predicted
whether, when, in what forms, or with what effective dates, the tax laws
applicable to us or our investors will be changed.
    
 
     Other Tax Liabilities. Even if we qualify as a REIT, we and our
subsidiaries may be subject to certain Federal, state and local taxes on our
income and property that could reduce operating cash flow.
 
POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES
 
     Our Charter limits ownership of our common stock by any single shareholder
to 8.7% of the outstanding shares (or 15% in the case of certain pension trusts,
registered investment companies and Mr. Considine). The Charter also prohibits
anyone from buying shares if the purchase would result in us losing our REIT
status. This could happen if a share transaction results in fewer than 100
persons owning all of our shares or in five or fewer persons, applying certain
broad attribution rules of the Internal Revenue Code, owning 50% or more of our
shares. If you or anyone else acquires shares in excess of the ownership limit
or in violation of the ownership requirements of the Internal Revenue Code for
REITs:
 
     - the transfer will be considered null and void;
 
     - we will not reflect the transaction on our books;
 
     - we may institute legal action to enjoin the transaction;
 
     - we may demand repayment of any dividends received by the affected person
       on those shares;
 
     - we may redeem the shares at their then current market price;
 
     - the affected person will not have any voting rights for those shares; and
 
     - the shares (and all voting and dividend rights of the shares) will be
       held in trust for the benefit of one or more charitable organizations
       designated by us.
 
     We may purchase the shares held in trust at a price equal to the lesser of
the price paid by the transferee of the shares or the then current market price.
If the trust transfers any of the shares, the affected person will receive the
lesser of the price he paid for the shares or the then current market price. An
individual who acquires shares that violate the above rules bears the risk that:
 
     - he may lose control over the power to dispose of the shares;
 
     - he may not recognize profit from the sale of such shares if the market
       price of the shares increases; and
 
     - he may be required to recognize a loss from the sale of such shares if
       the market price decreases.
 
OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO ACQUIRE
CONTROL OF THE COMPANY
 
     Ownership Limit. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our Board of Directors.
 
   
     Preferred Stock. Our Charter authorizes our Board of Directors to issue up
to 510,750,000 shares of capital stock. As of October 1, 1998, 486,027,500
shares were classified as Class A Common Stock, 262,500 shares were classified
as Class B Common Stock and 24,460,000 were classified as preferred stock. Under
the Charter, our Board of Directors has the authority to classify and reclassify
any of our unissued shares of capital stock into shares of preferred stock with
such preferences, rights, powers and restrictions as the Board of
    
 
                                        7
<PAGE>   116
 
Directors may determine. The authorization and issuance of preferred stock could
have the effect of delaying or preventing someone from taking control of us,
even if a change in control were in our shareholders' best interests.
 
     Maryland Business Statutes. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our shareholders' best interests. The
Maryland General Corporation Law restricts mergers and other business
combination transactions between us and any person who acquires beneficial
ownership of shares of our stock representing 10% or more of the voting power
without our Board of Directors' prior approval. Any such business combination
transaction could not be completed until five years after the person acquired
such voting power, and only with the approval of shareholders representing 80%
of all votes entitled to be cast and 66% of the votes entitled to be cast,
excluding the interested shareholder. Maryland law also provides that a person
who acquires shares of our stock that represent 20% or more of the voting power
in electing directors will have no voting rights unless approved by a vote of
two-thirds of the shares eligible to vote.
 
RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS
 
   
     We refer to interests in the AIMCO Operating Partnership as "OP Units." The
Partnership Common Units are referred to as "Common OP Units" and the
Partnership Preferred Units are referred to as "Preferred OP Units." The
agreement of limited partnership of the AIMCO Operating Partnership is referred
to as the "AIMCO Operating Partnership Agreement."
    
 
   
     Restrictions on Transferability of OP Units. There is no public market for
our OP Units. In addition, our partnership agreement restricts the
transferability of OP Units. Until the expiration of a one year holding period,
subject to certain exceptions, investors may not transfer OP Units without the
consent of the general partner of the AIMCO Operating Partnership. Thereafter
investors may transfer such OP Units subject to the satisfaction of certain
conditions, including the general partner's right of first refusal. See
"Description of OP Units -- Transfers and Withdrawals." We have no plans to list
our OP Units on a securities exchange. It is unlikely that any person will make
a market in our OP Units, or that an active market for our OP Units will
develop. If a market for our OP Units develops and our OP Units are considered
"readily tradable" on a "secondary market (or the substantial equivalent
thereof)," the AIMCO Operating Partnership would be classified as a publicly
traded partnership for federal income tax purposes. See "-- Tax Treatment is
Dependent on Partnership Status; Publicly Traded Partnership Risks."
    
 
     Cash Distributions Are Not Guaranteed and May Fluctuate with Partnership
Performance. Although we make quarterly distributions on our OP Units, there can
be no assurance regarding the amounts of available cash that the AIMCO Operating
Partnership will generate or the portion that the general partner will choose to
distribute. The actual amounts of available cash will depend upon numerous
factors, including profitability of operations, required principal and interest
payments on our debt, the cost of acquisitions (including related debt service
payments), our issuance of debt and equity securities, fluctuations in working
capital, capital expenditures, adjustments in reserves, prevailing economic
conditions and financial, business and other factors, some of which may be
beyond the our control. Cash distributions are dependent primarily on cash flow,
including from reserves, and not on profitability, which is affected by non-cash
items. Therefore, cash distributions may be made during periods when the we
record losses and may not be made during periods when we record profits. We make
quarterly distributions to holders of Common OP Units (on a per unit basis) that
generally are equal to the dividends paid on the Class A Common Stock (on a per
share basis). However, such distributions will not necessarily continue to be
equal to such dividends.
 
     Our partnership agreement gives our general partner discretion in
establishing reserves for the proper conduct of the partnership's business that
will affect the amount of available cash. We are required to make reserves for
the future payment of principal and interest under our credit facilities and
other indebtedness. In addition, our credit facilities limit our ability to
distribute cash to holders of our OP Units. As a result of these and other
factors, there can be no assurance regarding our actual levels of cash
distributions on our OP Units,
 
                                        8
<PAGE>   117
 
and our ability to distribute cash may be limited during the existence of any
events of default under any of our debt instruments.
 
   
     The AIMCO GP Manages and Operates the AIMCO Operating Partnership; OP
Unitholders Have Limited Voting Rights. The AIMCO GP manages and operates the
AIMCO Operating Partnership. Unlike the holders of common stock in a
corporation, OP Unitholders have only limited voting rights on matters affecting
the AIMCO Operating Partnership's business. OP Unitholders have no right to
elect the AIMCO GP on an annual or other continuing basis, and the AIMCO GP may
not be removed by OP Unitholders. As a result, OP Unitholders have limited
influence on matters affecting the operation of the AIMCO Operating Partnership
and third parties may find it difficult to attempt to gain control or influence
the activities of the AIMCO Operating Partnership.
    
 
   
     We May Issue Additional Partnership Interests, Diluting OP Unitholders'
Interests. We may issue an unlimited number of additional OP Units or other
limited partner interests of the AIMCO Operating Partnership for such
consideration and on such terms as may be established by the AIMCO GP in its
sole discretion, in most cases, without the approval of OP Unitholders. The
effect of any such issuance may be to dilute the interests of OP Unitholders in
distributions by the AIMCO Operating Partnership.
    
 
     OP Unitholders May Not Have Limited Liability in Certain Circumstances. The
limitations on the liability of limited partners for the obligations of a
limited partnership have not been clearly established in some states. If it were
determined that the AIMCO Operating Partnership had been conducting business in
any state without compliance with the applicable limited partnership statute, or
that the right or the exercise of the right by the OP Unitholders as a group to
make certain amendments to the AIMCO Operating Partnership Agreement or to take
other action pursuant to the AIMCO Operating Partnership Agreement constituted
participation in the "control" of the AIMCO Operating Partnership's business,
then an OP Unitholder could be held liable under certain circumstances for the
AIMCO Operating Partnership's obligations to the same extent as the AIMCO GP.
 
     Conflicts of Interest and Fiduciary Responsibility. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the AIMCO GP and its affiliates, on the one hand, and the AIMCO
Operating Partnership or any partner thereof, on the other. The directors and
officers of the AIMCO GP have fiduciary duties to manage the AIMCO GP in a
manner beneficial to AIMCO, as the sole stockholder of the AIMCO GP. At the same
time, the AIMCO GP, as general partner, has fiduciary duties to manage the AIMCO
Operating Partnership in a manner beneficial to the AIMCO Operating Partnership
and its partners. The duties of the AIMCO GP, as general partner, to the AIMCO
Operating Partnership and its partners, therefore, may come into conflict with
the duties of the directors and officers of the AIMCO GP to its sole
stockholder, AIMCO. Such conflicts of interest might arise in the following
situations, among others:
 
     - Decisions of the AIMCO GP with respect to the amount and timing of cash
       expenditures, borrowings, issuances of additional interests and reserves
       in any quarter will affect whether or the extent to which there is
       available cash to make distributions in a given quarter.
 
     - Under the terms of its partnership agreement, the AIMCO Operating
       Partnership will reimburse the AIMCO GP and its affiliates for costs
       incurred in managing and operating the AIMCO Operating Partnership,
       including compensation of officers and employees.
 
     - Whenever possible, the AIMCO GP seeks to limit the AIMCO Operating
       Partnership's liability under contractual arrangements to all or
       particular assets of the AIMCO Operating Partnership, with the other
       party thereto to have no recourse against the AIMCO GP or its assets.
 
     - Any agreements between the AIMCO Operating Partnership and the AIMCO GP
       and its affiliates will not grant to the OP Unitholders, separate and
       apart from the AIMCO Operating Partnership, the right to enforce the
       obligations of the AIMCO GP and such affiliates in favor of the AIMCO
       Operating Partnership. Therefore, the AIMCO GP, in its capacity as the
       general partner of the AIMCO Operating Partnership, will be primarily
       responsible for enforcing such obligations.
 
                                        9
<PAGE>   118
 
     - Under the terms of the AIMCO Operating Partnership Agreement, the AIMCO
       GP is not restricted from causing the AIMCO Operating Partnership to pay
       the AIMCO GP or its affiliates for any services rendered on terms that
       are fair and reasonable to the AIMCO Operating Partnership or entering
       into additional contractual arrangements with any of such entities on
       behalf of the AIMCO Operating Partnership. Neither the AIMCO Operating
       Partnership Agreement nor any of the other agreements, contracts and
       arrangements between the AIMCO Operating Partnership, on the one hand,
       and the AIMCO GP and its affiliates, on the other, are or will be the
       result of arms-length negotiations.
 
     Unless otherwise provided for in the relevant partnership agreement,
Delaware law generally requires a general partner of a Delaware limited
partnership to adhere to fiduciary duty standards under which it owes its
limited partners the highest duties of good faith, fairness and loyalty and
which generally prohibit such general partner from taking any action or engaging
in any transaction as to which it has a conflict of interest. The AIMCO
Operating Partnership Agreement expressly authorizes the AIMCO GP to enter into,
on behalf of the AIMCO Operating Partnership, a right of first opportunity
arrangement and other conflict avoidance agreements with various affiliates of
the AIMCO Operating Partnership and the AIMCO GP, on such terms as the AIMCO GP,
in its sole and absolute discretion, believes are advisable. The latitude given
in the AIMCO Operating Partnership Agreement to the AIMCO GP in resolving
conflicts of interest may significantly limit the ability of an OP Unitholder to
challenge what might otherwise be a breach of fiduciary duty. The AIMCO GP
believes, however, that such latitude is necessary and appropriate to enable it
to serve as the general partner of the AIMCO Operating Partnership without undue
risk of liability.
 
     The AIMCO Operating Partnership Agreement expressly limits the liability of
the AIMCO GP by providing that the AIMCO GP, and its officers and directors will
not be liable or accountable in damages to the AIMCO Operating Partnership, the
limited partners or assignees for errors in judgment or mistakes of fact or law
or of any act or omission if the AIMCO GP or such director or officer acted in
good faith. In addition, the AIMCO Operating Partnership is required to
indemnify the AIMCO GP, its affiliates and their respective officers, directors,
employees and agents to the fullest extent permitted by applicable law, against
any and all losses, claims, damages, liabilities, joint or several, expenses,
judgments, fines and other actions incurred by the AIMCO GP or such other
persons, provided that the AIMCO Operating Partnership will not indemnify for
(i) willful misconduct or a knowing violation of the law or (ii) for any
transaction for which such person received an improper personal benefit in
violation or breach of any provision of the AIMCO Operating Partnership
Agreement.
 
     The provisions of Delaware law that allow the common law fiduciary duties
of a general partner to be modified by a partnership agreement have not been
resolved in a court of law, and the AIMCO GP has not obtained an opinion of
counsel covering the provisions set forth in the AIMCO Operating Partnership
Agreement that purport to waive or restrict the fiduciary duties of the AIMCO GP
that would be in effect under common law were it not for the AIMCO Operating
Partnership Agreement.
 
     Certain Tax Risks Associated with an Investment in the OP Units. For a
general discussion of certain federal income tax consequences resulting from the
acquisition, holding, exchanging, and otherwise disposing of OP Units, see
"Federal Income Taxation of the AIMCO Operating Partnership and OP Unitholders."
 
     Tax Treatment is Dependent on Partnership Status; Publicly Traded
Partnership Risks. The availability to an OP Unitholder of the federal income
tax benefits of an investment in the AIMCO Operating Partnership depends on the
classification of the AIMCO Operating Partnership as a partnership for federal
income tax purposes. In the opinion of our legal counsel, which opinion is based
upon certain assumptions and representations by the AIMCO Operating Partnership
and on opinions of local counsel, with respect to matters of local law, the
AIMCO Operating Partnership will be classified as a partnership for federal
income tax purposes. The opinion is expressed as of its date and our counsel has
no obligation to advise OP Unitholders of any subsequent change in the matters
stated, represented or assumed or any subsequent change in the applicable law.
No advance ruling has been or will be sought from the IRS as to the
classification of the AIMCO Operating Partnership as a partnership. An opinion
of counsel is not binding on the IRS, and no assurance can be given that the IRS
will not challenge the status of the AIMCO Operating Partnership as a
partnership.
 
                                       10
<PAGE>   119
 
   
     If a market for the OP Units develops and the OP Units are considered
"readily tradable" on a "secondary market (or the substantial equivalent
thereof)," the AIMCO Operating Partnership would be classified as a publicly
traded partnership. We believe and intend to take the position that the AIMCO
Operating Partnership should not be classified as a publicly traded partnership
because (i) our OP Units are not traded on an established securities market and
(ii) our OP Units should not be considered readily tradable on a secondary
market or the substantial equivalent thereof. The determination of whether
interests in a partnership are readily tradable on a secondary market or the
substantial equivalent thereof, however, depends on various facts and
circumstances (including facts that are not within the control of the AIMCO
Operating Partnership). Although the Treasury regulations promulgated by the
U.S. Treasury Department under the Internal Revenue Code (the "Treasury
Regulations") and an IRS pronouncement provide limited safe harbors, which, if
satisfied, will prevent a partnership's interests from being treated as readily
tradable on a secondary market or the substantial equivalent thereof, the AIMCO
Operating Partnership may not have satisfied any of these safe harbors in its
previous tax years. In addition, because the AIMCO Operating Partnership's
ability to satisfy a safe harbor may involve facts that are not within its
control, it is impossible to predict whether the AIMCO Operating Partnership
will satisfy a safe harbor in future tax years. Such safe harbors are not
intended to be substantive rules for the determination of whether partnership
interests are readily tradable on a secondary market or the substantial
equivalent thereof, and consequently, the failure to meet these safe harbors
will not necessarily cause the AIMCO Operating Partnership to be treated as a
publicly traded partnership. No assurance can be given, however, that the IRS
will not assert that partnerships such as the AIMCO Operating Partnership
constitute publicly traded partnerships, or that facts and circumstances will
not develop which could result in the AIMCO Operating Partnership being treated
as a publicly traded partnership.
    
 
   
     If the AIMCO Operating Partnership were characterized as a publicly traded
partnership, it would nevertheless not be taxable as a corporation as long as
90% or more of its gross income consists of "qualifying income." In general,
qualifying income includes interest, dividends, real property rents (as defined
by section 856 of the Internal Revenue Code) and gain from the sale or
disposition of real property. We believe that more than 90% of the gross income
of the AIMCO Operating Partnership consists of qualifying income and we expect
that more than 90% of its gross income in future tax years will consist of
qualifying income. In such event, even if the AIMCO Operating Partnership were
characterized as a publicly traded partnership, it would not be taxable as a
corporation. If the AIMCO Operating Partnership were characterized as a publicly
traded partnership, however, each OP Unitholder would be subject to special
rules under section 469 of the Internal Revenue Code. See "Federal Income
Taxation of the AIMCO Operating Partnership and OP Unitholders -- Limitations on
Deductibility of Losses; "Passive Activity Loss" Limitation." No assurance can
be given that the actual results of the AIMCO Operating Partnership's operations
for any one taxable year will enable it to satisfy the qualifying income
exception.
    
 
   
     If the AIMCO Operating Partnership were characterized as an association or
publicly traded partnership taxable as a corporation (because it did not meet
the qualifying income exception discussed above), it would be subject to tax at
the entity level as a regular corporation and OP Unitholders would be subject to
tax in the same manner as stockholders of a corporation. Thus, the AIMCO
Operating Partnership would be subject to federal tax (and possibly state and
local taxes) on its net income, determined without reduction for any
distributions made to the OP Unitholders, at regular federal corporate income
tax rates, thereby reducing the amount of any cash available for distribution to
the OP Unitholders, which reduction could also materially and adversely impact
the liquidity and value of the OP Units. In addition, the AIMCO Operating
Partnership's items of income, gain, loss, deduction and credit would not be
passed through to the OP Unitholders and the OP Unitholders would not be subject
to tax on the income earned by the AIMCO Operating Partnership. Distributions
received by an OP Unitholder from the AIMCO Operating Partnership, however,
would be treated as dividend income for federal income tax purposes, subject to
tax as ordinary income to the extent of current and accumulated earnings and
profits of the AIMCO Operating Partnership, and the excess, if any, as a
nontaxable return of capital to the extent of the OP Unitholder's adjusted tax
basis in his AIMCO Operating Partnership interest (without taking into account
partnership liabilities), and thereafter as gain from the sale of a capital
asset. Characterization of the AIMCO Operating Partnership as an association or
publicly traded partnership taxable as a corporation would also result in the
termination of AIMCO's status as a REIT for
    
 
                                       11
<PAGE>   120
 
federal income tax purposes which would have a material adverse impact on AIMCO.
See "Federal Income Taxation of the AIMCO Operating Partnership and OP
Unitholders -- Partnership Status." No assurances can be given that the IRS
would not challenge the status of the AIMCO Operating Partnership as a
"partnership" which is not "publicly traded" for federal income tax purposes or
that a court would not reach a result contrary to such positions. Accordingly,
each prospective investor is urged to consult his tax advisor regarding the
classification and treatment of the AIMCO Operating Partnership as a
"partnership" for federal income tax purposes.
 
   
     Consequences of Exchanging Property for OP Units. In general, no gain or
loss will be recognized for federal income tax purposes by a person contributing
property to the AIMCO Operating Partnership (the "Contributing Partner") in
exchange for OP Units, and the Contributing Partner will take a tax basis in the
OP Unit received equal to his adjusted tax basis in the contributed property.
Notwithstanding this general rule of nonrecognition, a Contributing Partner may
recognize a gain where the property transferred is subject to liabilities, or
the AIMCO Operating Partnership assumes liabilities in connection with the
transfer of property, and the amount of such liabilities exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to such person as
determined immediately after the transfer. Such excess is treated as a deemed
distribution of cash to the Contributing Partner from the AIMCO Operating
Partnership which, in turn, is treated as a nontaxable return of capital to the
extent of the Contributing Partner's adjusted tax basis in his OP Unit and
thereafter as gain from the sale of such partnership interest. If the
Contributing Partner transfers property to the AIMCO Operating Partnership and
the adjusted tax basis of the property differs from its fair market value, then
AIMCO Operating Partnership tax items must be allocated, for federal income tax
purposes, in a manner such that the Contributing Partner is charged with the
unrealized gain, or benefits from the unrealized loss, associated with the
property at the time of the contribution. See "Federal Income Taxation of the
AIMCO Operating Partnership and OP Unitholders -- Tax Consequences Upon
Contribution of Property to the AIMCO Operating Partnership."
    
 
   
     There are a variety of transactions that the AIMCO Operating Partnership
may in its sole discretion undertake following such contribution with respect to
the contributed property or the debt securing such property which could cause
the Contributing Partner to recognize taxable gain, even though little or no
cash is distributable to him as a result thereof. Such transactions include but
are not limited to (i) the sale of a particular property, which could result in
an allocation of gain only to those OP Unitholders who received OP Units for
such property (even if cash attributable to sale proceeds were distributed
proportionately to all OP Unitholders); and (ii) a reduction in the nonrecourse
debt allocable to property (either because such debt becomes a recourse
liability or is paid off with cash flow, new equity, or proceeds of debt secured
by other property of the AIMCO Operating Partnership), which would result in a
deemed distribution of money to the OP Unitholders who received OP Units for
such property as well as to the other OP Unitholders. See "Federal Income
Taxation of the AIMCO Operating Partnership and OP Unitholders -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
and "Federal Income Taxation of the AIMCO Operating Partnership and OP
Unitholders -- Cash Distributions." The AIMCO Operating Partnership Agreement
grants the AIMCO GP broad authority to undertake such transactions and does not
grant the OP Unitholders affected by these actions any rights to prevent the
AIMCO GP from taking such actions. Even if the AIMCO GP does not intend to sell
or otherwise dispose of contributed property or to reduce the debt, if any,
securing such property within any specified time period after the Contributing
Partner transfers such property to the AIMCO Operating Partnership, it is
possible that future economic, market, legal, tax or other considerations may
cause the AIMCO Operating Partnership to dispose of the contributed property or
to reduce its debt. In this regard, the AIMCO Operating Partnership Agreement
provides that the AIMCO GP, while acting in its capacity as general partner of
the AIMCO Operating Partnership, may, but is not required to, take into account
the tax consequences to the OP Unitholders of its actions in such capacity. The
AIMCO GP intends to make decisions in its capacity as general partner of the
AIMCO Operating Partnership so as to maximize the profitability of the AIMCO
Operating Partnership as a whole, independent of the tax effects on individual
OP Unitholders.
    
 
     Tax Liability Exceeding Cash Distribution. An OP Unitholder will be
required to pay federal income tax and, in certain cases, state and local income
taxes, on his allocable share of the AIMCO Operating
 
                                       12
<PAGE>   121
 
Partnership's income, even if he receives no cash distributions from the AIMCO
Operating Partnership. No assurance can be given that an OP Unitholder will
receive cash distributions equal to his allocable share of taxable income from
the AIMCO Operating Partnership or even the tax liability to him resulting from
that income. Further, upon the sale of his OP Units, an OP Unitholder may incur
a tax liability in excess of the amount of cash received. See "Federal Income
Taxation of the AIMCO Operating Partnership and OP Unitholders -- Taxation of OP
Unitholders of AIMCO Operating Partnership," and "Federal Income Taxation of the
AIMCO Operating Partnership and OP Unitholders -- Sale, Redemption, or Exchange
of OP Units."
 
   
     Deductibility of Losses. An OP Unitholder's ability to use his allocable
share of losses, if any, from the AIMCO Operating Partnership at the end of the
taxable year in which the loss is incurred may be limited by certain provisions
of the Internal Revenue Code. See "Federal Income Taxation of the AIMCO
Operating Partnership and OP Unitholders -- Limitations on Deductibility of
Losses."
    
 
     Potential Audits. The AIMCO Operating Partnership's tax return may be
audited, and any such audit could result in an audit of an OP Unitholder's tax
return as well as increased liabilities for taxes because of adjustments
resulting from the audit. No assurance can be given that the AIMCO Operating
Partnership will not be audited by the IRS or various state authorities or that
tax adjustments will not be made. Any adjustments in the AIMCO Operating
Partnership's tax return will lead to adjustments in an OP Unitholder's tax
return and may lead to audits of an OP Unitholder's tax return and adjustments
of items unrelated to the AIMCO Operating Partnership. Each OP Unitholder would
bear the cost of any expenses incurred in connection with an examination of such
OP Unitholder's tax return. See "Federal Income Taxation of the AIMCO Operating
Partnership and OP Unitholders -- Information Returns and Audit Procedures."
 
     State, Local and Other Tax Considerations. In addition to federal income
taxes, the AIMCO Operating Partnership and its OP Unitholders may be subject to
state, local and foreign taxation in various jurisdictions in which the AIMCO
Operating Partnership does business, owns property or resides. See "Other Tax
Consequences -- State, Local and Foreign Taxes."
 
     Tax Gain or Loss on Disposition of OP Units. An OP Unitholder who sells OP
Units will recognize gain or loss equal to the difference between the amount
realized (including his share of AIMCO Operating Partnership nonrecourse
liabilities) and his adjusted tax basis in such OP Units. Thus, prior AIMCO
Operating Partnership distributions in excess of cumulative net taxable income
in respect of an OP Unit which decreased an OP Unitholder's tax basis in such OP
Unit will, in effect, become taxable income if the OP Unit is sold at a price
greater than the OP Unitholder's tax basis in such OP Units, even if the price
is less than his original cost. A portion of the amount realized (whether or not
representing gain) may be ordinary income.

                     SECURITIES COVERED BY THIS PROSPECTUS
 
     The securities covered by this Prospectus (the "Securities") may be offered
and issued from time to time by AIMCO or the AIMCO Operating Partnership in
connection with acquisitions of businesses, properties, securities or other
assets. In addition, AIMCO may issue (i) shares of its Class A Common Stock, par
value $0.01 per share ("Class A Common Stock") covered hereby upon conversion of
shares its Preferred Stock, par value $0.01 per share ("Preferred Stock"), (ii)
shares of its Preferred Stock covered hereby and shares of its Class A Common
Stock covered hereby, in each case in exchange for Partnership Preferred Units
of the AIMCO Operating Partnership ("Preferred OP Units") tendered for
redemption pursuant to the AIMCO Operating Partnership Agreement and (iii)
shares of its Class A Common Stock covered hereby in exchange for Partnership
Common Units of the AIMCO Operating Partnership ("Common OP Units" and together
with the Preferred OP Units, the "OP Units") tendered for redemption pursuant to
the AIMCO Operating Partnership Agreement.
 
     It is expected that the terms of acquisitions involving the issuance of the
Securities will be determined by direct negotiations with owners or controlling
persons of the business, properties, securities or other assets to be acquired
or through exchange offers. It is expected that any shares of Class A Common
Stock or Common OP Units issued will be valued at prices based on or related to
market prices for the Class A Common Stock at or near the time the terms of such
acquisition are established or at or near the time such Securities are
delivered, or based on average market prices for periods ending at or near such
times. No underwriting discounts or commissions will be paid, although brokers'
or finders' fees may be paid from time to time with respect to specific
acquisitions, and AIMCO or the AIMCO Operating Partnership may issue the
Securities in full or partial payment of such fees. Any person receiving such
fees may be deemed to be an "underwriter," within the meaning of the Securities
Act.
 
     This Prospectus has also been prepared for use by the persons who may
receive from AIMCO or the AIMCO Operating Partnership Securities covered by the
Registration Statement in acquisitions and who may be entitled to offer such
Securities under circumstances requiring the use of a Prospectus (such persons
being referred to under this caption as "Securityholders"); provided, however,
that no Securityholder will be authorized to use this Prospectus for any offer
of such Security without first obtaining the consent of AIMCO and the AIMCO
Operating Partnership. AIMCO and the AIMCO Operating Partnership may consent to
the use of this Prospectus for a limited period of time by the Securityholders
and subject to limitations and conditions which may be varied by agreement
between AIMCO and the AIMCO Operating Partnership and the Securityholders.
Resales of such Securities may be made on the NYSE or such other exchange on
which the Securities may be listed, in the over-the-counter market, in private
transactions or pursuant to underwriting agreements.
 
     Agreements with Securityholders permitting use of this Prospectus may
provide that any such offering be effected in an orderly manner through
securities dealers, acting as broker or dealer, selected by AIMCO and the AIMCO
Operating Partnership; that Securityholders enter into custody agreements with
one or more banks with respect to such shares; and that sales be made only by
one or more of the methods described in this Prospectus, as appropriately
supplemented or amended when required. The Securityholders may be deemed to be
underwriters within the meaning of the Securities Act.
 
     When resales are to be made through a broker or dealer selected by AIMCO
and the AIMCO Operating Partnership, it is anticipated that a member firm of the
NYSE may be engaged to act as the Securityholders' agent in the sale of shares
by such Securityholders. The member firm will be entitled to commissions
(including negotiated commissions to the extent permissible). Sales of shares by
the member firm may be made on the NYSE or other exchange from time to time at
prices related to prices then prevailing. Any such sales may be by block trade.
Any such member firm may be deemed to be an underwriter within the meaning of
the Securities Act and any commissions earned by such member firm may be deemed
to be underwriting discounts and commissions under such act.
 
     Upon AIMCO and the AIMCO Operating Partnership being notified by a
Securityholder that any block trade has taken place, a supplementary prospectus,
if required, will be filed pursuant to Rule 424 under the Securities Act,
disclosing the name of the member firm, the number of shares involved, the price
at which
 
                                       14
<PAGE>   123
 
such shares were sold by such Securityholder, and the commissions to be paid by
such Securityholder to such member firm.
 
     This Prospectus may be supplemented or amended from time to time to reflect
its use for resales by persons who received Securities for whom AIMCO and the
AIMCO Operating Partnership have consented to the use of this Prospectus in
connection with resales of such Securities.
 
     In addition to the Securities offered hereby, AIMCO and the AIMCO Operating
Partnership may from time to time issue additional Securities through public
offerings or private placements. AIMCO and the AIMCO Operating Partnership may
make such future issuances of Securities in connection with its acquisition of
other businesses, properties, securities or other assets in business combination
transactions or for other purposes.

(1) On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
    shares of Class A Common Stock. On such date, AIMCO and Property Asset
    Management, L.L.C., and its affiliated companies and PDI Realty Enterprises,
    Inc. (collectively, the "Company Predecessors") engaged in a business
    combination and consummated a series of related transactions which enabled
    the Company to continue and to expand the property management and related
    businesses of the Company Predecessors.
 
(2) The ratio of earnings to fixed charges for the Company was computed by
    dividing earnings by fixed charges. For this purpose, "earnings" consists of
    income before minority interests (which includes equity in earnings of
    unconsolidated subsidiaries and partnerships only to the extent of dividends
    and distributions received) plus fixed charges (other than any interest
    which has been capitalized); and "fixed charges" consists of interest
    expense (including amortization of loan costs) and interest which has been
    capitalized. The ratio of earnings to fixed charges for the Company
    Predecessors was computed by dividing earnings by fixed charges. For this
    purpose, "earnings" consists of income (loss) before extraordinary items and
    income taxes plus fixed charges and "fixed charges" consists of interest
    expense (including amortization of loan costs).
 
(3) The earnings of the Company Predecessors for the period from January 1, 1994
    to July 28, 1994 were inadequate to cover fixed charges by $1,463,000.
 
(4) The ratio of earnings to combined fixed charges and preferred stock
    dividends for the Company was computed by dividing earnings by the total of
    fixed charges and preferred stock dividends. For this purpose, "earnings"
    consists of income before minority interests (which includes equity in
    earnings of unconsolidated subsidiaries and partnerships only to the extent
    of dividends and distributions received) plus fixed charges (other than any
    interest which has been capitalized); "fixed charges" consists of interest
    expense (including amortization of loan costs) and interest which has been
    capitalized; and "preferred stock dividends" consists of the amount of
    pre-tax earnings that would be required to cover preferred stock dividend
    requirements.
 
(5) The Company Predecessors did not have any shares of preferred stock
    outstanding during the period from January 1, 1993 through July 28, 1994.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of Class A Common Stock and issued 966,000 shares of convertible
     preferred stock and 513,514 unregistered shares of Class A Common Stock. On
     such date, the Company and the Company Predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     the Company to continue and expand the property management and related
     businesses of the Company Predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of Class A Common Stock were repurchased
     by AIMCO in 1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO.
 
   
(c)  In the second quarter of 1996, the Company reorganized its ownership of the
     service company business. Prior to the 1996 reorganization, the Company
     reported the service company business on the equity method. After the 1996
     reorganization, the service company business was conducted by a limited
     partnership controlled by the Company and was, therefore, consolidated. The
     Company has restated the balance sheet as of December 31, 1995 and 1994,
     and the statements of income and statements of cash flows for the year
     ended December 31, 1995 and the period from January 10, 1994 through
     December 31, 1994 to reflect the change. The restatement has no impact on
     net income, but does increase third party and affiliate management and
     other income, management and other expenses, amortization of management
     company goodwill and depreciation of non-real estate assets. In the third
     quarter of 1998, the Company reorganized its ownership of the service
     company business so that it is now conducted by the management companies,
     which are not consolidated.
    
 
(d)  Represents the Company's share of earnings from 83,431 units in which the
     Company purchased an equity interest from the NHP Real Estate Companies.
 
   
(e)  Represents the Company's equity earnings in the unconsolidated
     subsidiaries.
    
 
(f)  The Company's management believes that the presentation of funds from
     operations ("FFO"), when considered with the financial data determined in
     accordance with generally accepted accounting principles ("GAAP"), provides
     a useful measure of the Company's performance. However, FFO does not
     represent cash flow and is not necessarily indicative of cash flow or
     liquidity available to the Company, nor should it be considered as an
     alternative to net income as an indicator of operating performance. The
     Board of Governors of the National Association of Real Estate Investment
     Trusts ("NAREIT") defines FFO as net income (loss), computed in accordance
     with GAAP, excluding gains and losses from debt restructuring and sales of
     property, plus real estate related depreciation and amortization
 
                                       18
<PAGE>   127
 
     (excluding amortization of financing costs), and after adjustments for
     unconsolidated partnerships and joint ventures. AIMCO calculates FFO
     consistent with the NAREIT definition, adjusted for AIMCO's minority
     interest in the AIMCO Operating Partnership, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. The Company's management believes
     that presentation of FFO provides investors with industry-accepted
     measurements which help facilitate an understanding of the Company's
     ability to make required dividend payments, capital expenditures and
     principal payments on its debt. There can be no assurance that AIMCO's
     basis of computing FFO is comparable with that of other REITs.
 
     The following is a reconciliation of income before minority interest in the

     Because AIMCO has elected to be taxed for federal income tax purposes as a
REIT, it is required to distribute annually to its stockholders at least 95% of
its "REIT taxable income," which, as defined by the Code and the Treasury
Regulations, is generally equivalent to net taxable ordinary income. AIMCO
measures its economic profitability and pays regular dividends to its
stockholders based on its operating results during the relevant period. The
future payment of dividends by AIMCO will be at the discretion of the AIMCO
Board of Directors and will depend on numerous factors, including financial
condition, capital requirements, the annual distribution requirements under the
provisions of the Code applicable to REITs and such other factors the AIMCO
Board of Directors deems relevant. See "Business of the Company -- Operating and
Financial Strategies; Dividend Policy."
    
 
   
     On January 22, 1998, the AIMCO Board of Directors voted to increase the
annual dividend rate on the Class A Common Stock to $2.25 per share. Such
dividend increase was effective commencing with the dividend with respect to the
fourth quarter of 1997 paid on February 13, 1998 and is subject to the factors
described above, including AIMCO's future results of operations. Historically,
the AIMCO Operating Partnership has made quarterly distributions to holders of
Common OP Units (on a per unit basis) that are equal to the dividends paid on
the Class A Common Stock (on a per share basis). Although this is expected to be
true in the future, there can be no assurance that distributions on the Common
OP Units will always be equal to the dividends on the Class A Common Stock. See
"Risk Factors -- Risks Associated With an Investment in OP Units."

                            BUSINESS OF THE COMPANY
 
   
     The Company is engaged in the ownership, acquisition, development,
expansion and management of multi-family apartment properties. As of October 1,
1998, the Company owned or managed 396,090 apartment units in 2,303 properties
located in 49 states, the District of Columbia and Puerto Rico. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, we were the largest owner and
manager of multifamily apartment properties in the United States. The "AIMCO
Properties" include:
    
 
   
     - "Owned Properties" -- properties that the Company owns or controls;
    
 
   
     - "Equity Properties" -- properties in which the Company owns a
       non-controlling (usually less than 30%) interest; and
    
 
   
     - "Managed Properties" -- properties that the Company manages for third
       parties and affiliates.
    
 
   
     As of October 1, 1998, the Company had 209 Owned Properties with 58,495
units, 1,335 Equity Properties with 239,789 units and 759 Managed Properties
with 97,716 units. The Company manages all of the Owned Properties, a majority
of the Equity Properties and all of the Managed Properties.
    
 
OPERATING AND FINANCIAL STRATEGIES
 
   
     The Company uses the following operating and financing strategies to
attempt to meet its objective of providing long-term, predictable FFO per share
(certain terms used herein are defined below in "-- Accounting Policies and
Definitions"):
    
 
     - Acquisition of Properties at Less Than Replacement Cost. The Company
       attempts to acquire properties at a significant discount to their
       replacement cost, which the Company believes will provide it with a
       competitive cost advantage in comparison to newly constructed properties.
 
   
     - Geographic Diversification. The Company operates in 49 states, the
       District of Columbia and Puerto Rico. This geographic diversification
       insulates the Company, to some degree, from inevitable downturns in any
       one market. Among Owned Properties and Equity Properties, Houston, Texas,
       the Company's largest single regional market, and Dallas, Texas, the
       Company's second largest regional market, accounted for approximately
       13.9% and 8.0%, respectively, of the properties in which the Company has
       an ownership interest, on a pro rata basis.
    
 
     - Market Growth. The Company seeks to operate in markets where population
       and employment growth are expected to exceed the national average and
       where it believes it can become a regionally significant owner or manager
       of properties. The average annual population and employment growth rates
       from 1990 to 1995 in The Company's five largest regional markets were
       2.3% and 2.6%, respectively, compared to national averages of 1.1% and
       1.7%, respectively. For the 1996 to 1999 period, average annual
       population and employment growth rates in The Company's five largest
       regional markets are forecasted to be 2.2% and 3.6%, respectively,
       compared with projected national averages of 0.9% and 2.0%, respectively.
 
     - Product Diversification. The Company's portfolio of apartment properties
       also span a range of apartment community types, both within and among
       markets. The Company's properties are located in both urban and suburban
       areas and range from garden apartments to high rises and from luxury
       townhomes to affordable properties.
 
     - Capital Replacement. The Company believes that the physical condition and
       amenities of its apartment communities are important factors in its
       ability to maintain and increase rental rates. The Company also believes
       that a program of regular maintenance of the quality of its apartments,
       rather than episodic renovation, contributes to the reliability of
       earnings per share. The Company presently allocates approximately $300
       annually per owned apartment unit for Capital Replacements and reserves
       unexpended amounts for future Capital Replacements. From time to time,
       the Company reevaluates its Capital Replacement requirements and updates
       the amount of its budgeted Capital
 
                                       22
<PAGE>   131
 
       Replacements per owned apartment unit accordingly. For the six months
       ended June 30, 1998, the Company charged approximately $6.6 million for
       Capital Replacements to its reserve, and spent approximately $13.5
       million, and had aggregate cumulative unexpended Capital Replacement
       reserves of approximately $2.4 million at June 30, 1998.
 
     - Debt Financing. The Company's strategy is generally to incur debt to
       increase its return on equity while maintaining acceptable interest
       coverage ratios. The Company seeks to match debt maturities to the
       character of the assets financed. Accordingly, the Company uses
       predominantly long-term, fixed-rate and self-amortizing debt in order to
       avoid the refunding or repricing risks of short-term borrowings. The
       Company also uses short-term debt financing to fund acquisitions and
       generally expects to refinance such borrowings with proceeds from equity
       offerings or long-term debt financings. As of June 30, 1998,
       approximately 6% of the Company's outstanding debt was short-term debt
       and 94% was long-term debt.
 
     - Dispositions. From time to time, the Company sells properties that do not
       meet its return on investment criteria or that are located in areas where
       the Company does not believe that the long-term real estate values
       justify the continued investment in the properties. Three properties in
       Houston and one property in each of Dallas and Phoenix were sold in
       October 1997. The Company recognized a net gain of approximately $2.8
       million on the sales.
 
            In January 1998, the Company sold the Sun Valley Apartments, an
       apartment community containing 430 apartment units located in Salt Lake
       City, Utah, for $11.5 million, less selling costs of $0.3 million. The
       Company recognized a $3.3 million gain on the sale. Cash proceeds from
       the sale were used to repay a portion of the AIMCO Operating
       Partnership's outstanding short-term indebtedness.
 
            In September 1998, the Company sold the Rillito Village Apartments,
       an apartment community containing 272 apartments units located in Tucson,
       Arizona, for $6.8 million. The Company recognized a gain on the sale of
       approximately $75,000 and used the cash proceeds to pay down a portion of
       the outstanding balance on the Credit Facilities and to pay closing
       costs.
 
     - Dividend Policy. The Company pays dividends and distributions to share
       its profitability with its stockholders and limited partners. For the
       years ended December 31, 1997, 1996 and 1995, AIMCO distributed 66.5%,
       72.3% and 75.1% of FFO to its stockholders. Amounts not distributed are
       available for reinvestment, stock repurchases, amortization of debt and
       provide a margin to insulate annual dividends from fluctuations in the
       Company's business. AIMCO's dividend for 1997 was $1.85 per share. It is
       the present policy of AIMCO to increase the dividend annually in an
       amount equal to one-half the rate of the projected increase in FFO,
       adjusted for capital replacements. In January 1998, AIMCO increased its
       dividend to $0.5625 per share per quarter, commencing with the February
       13, 1998 dividend payment which is equivalent to an annualized dividend
       of $2.25 per share of Class A Common Stock. The minimum annual
       distribution requirement for REITs, which require the distribution of
       approximately 95% of "REIT taxable income" (see "Federal Income Taxation
       of AIMCO and AIMCO Stockholders -- General"), may result in dividends
       increasing at a greater rate in the future.
 
GROWTH STRATEGIES
 
     The Company seeks growth through two primary sources -- acquisition and
internal expansion.
 
   
     Acquisition Strategies. The Company believes its acquisition strategies
will increase profitability and predictability of earnings by increasing its
geographic diversification, economies of scale and opportunities to provide
traditional ancillary services to tenants at the AIMCO Properties. Since AIMCO's
initial public offering in July 1994 (the "AIMCO IPO"), the Company has
completed numerous acquisition transactions, expanding its portfolio of owned or
managed properties from 132 apartment properties with 29,343 units to 2,303
apartment properties with 396,090 units as of October 1, 1998.
    
 
                                       23
<PAGE>   132
 
     The Company believes that its demonstrated ability to evaluate and complete
acquisitions, its property management record and its economies of scale, to the
extent that the Company can operate a property more efficiently than the
existing owner or some competing purchasers, all provide credibility and
advantage in negotiating acquisitions. In addition, the ability to issue OP
Units to sellers of properties may provide tax deferral opportunities to sellers
and could give the Company an advantage over competing buyers that cannot offer
such tax deferral opportunities. The Company acquires additional properties
primarily in three ways:
 
     - Direct Acquisitions. The Company may directly acquire individual
       properties or portfolios and controlling interests in entities that own
       or control such properties or portfolios. During the year ended December
       31, 1997, the Company has directly acquired 44 apartment properties for a
       total consideration of $467.4 million, consisting of $191.0 million in
       cash, approximately 1.9 million Common OP Units valued at $56.0 million
       and the assumption or incurrence of $220.4 million of indebtedness. See
       "-- Recent Property Acquisitions and Dispositions."
 
     - Acquisition of Managed Properties. The Company believes that its property
       management operations support its acquisition activities. Its
       relationships with owners of the Managed Properties may provide it with a
       means of learning of acquisition opportunities at an early stage of the
       sale process. In addition, its familiarity with the property and its
       ability to quickly evaluate the property give it an advantage in pursuing
       and completing any such acquisition in a timely fashion. Since the AIMCO
       IPO, the Company has acquired 12 properties comprising 3,530 units from
       its managed portfolio for $129.0 million.
 
     - Increasing its Interest in Partnerships. For properties where the Company
       owns a general partnership interest in the property-owning partnership,
       the Company may seek to acquire, subject to its fiduciary duties, the
       outstanding limited partnership interests for cash or, in some cases, in
       exchange for Common OP Units. After consummation of the Insignia Merger,
       the AIMCO Operating Partnership intends to offer to purchase limited
       partnership interests in syndicated real estate limited partnerships in
       which AIMCO holds partnership interests. The AIMCO Operating Partnership,
       subject to applicable law, plans to offer to purchase certain of such
       limited partnership interests in exchange for (i) equity securities of
       the AIMCO Operating Partnership to be issued pursuant to the Registration
       Statement of which this Prospectus forms a part, (ii) cash or (iii) a
       combination of such equity securities and cash. Such offers are expected
       to include terms that allow limited partners to continue to hold their
       limited partnership interests.
 
     - In November 1996, the Company acquired the English Partnerships, which
       owned 22 apartment properties. The Company subsequently purchased
       pursuant to tender offers to acquire all of the outstanding limited
       partnership interests of 25 of the English Partnerships, approximately
       46%, in the aggregate, of the outstanding limited partnership interests
       in such partnerships for $15.0 million in cash and approximately 71,500
       OP Units valued at $1.7 million.
 
     - As of December 31, 1997, the Company has also commenced tender offers to
       acquire all of the outstanding limited partnership interests in 26
       partnerships owning 25 properties for an aggregate amount of
       approximately $79.0 million. Through September 30, 1997, pursuant to such
       tender offers, the Company has purchased approximately 20.2%, in the
       aggregate, of the outstanding limited partnership interests for $16.0
       million in cash.
 
     Internal Growth Strategies. The Company pursues internal growth through the
following strategies:
 
     - Revenue Increases. The Company increases rents where feasible and seeks
       to improve occupancy rates. The Company believes that its policy of
       capital improvements, amenities and customer service allows it to
       maintain demand and to increase its rents above the rate of inflation in
       the local market. The Company's "same store" revenues from the Owned
       Properties (based on properties owned from period to period) have grown
       by 3.3% from the fiscal year ended December 31, 1995 to that ended
       December 31, 1996, and by 2.1% from the year ended December 31, 1996 to
       that ended December 31, 1997, compared to an urban consumer price
       inflation rate of 2.8% and 2.3% over the same periods.
 
                                       24
<PAGE>   133
 
     - Redevelopment of Properties. The Company believes redevelopment of
       selected properties in superior locations provides advantages over
       development of new properties, because, compared with new development,
       redevelopment generally can be accomplished with relatively lower
       financial risk, in less time and with reduced delays attributable to
       governmental regulation. Recently the Company acquired and redeveloped
       Sun Katcher, a 360-unit property in Jacksonville, Florida, at a cost of
       $8.9 million, including $4.9 million in redevelopment costs. The Company
       also recently commenced the renovation and upgrading of Bay West, a
       376-unit property in Tampa, Florida, for a projected cost of $4.8
       million, to reposition the property in the marketplace. In addition, the
       Company expects to undertake a major renovation of the Morton Towers
       apartments, a 1,277 unit property located in Miami Beach, Florida, at an
       estimated cost of $35 million. The Company generally finances
       redevelopment initially with borrowings from the Credit Facilities, and
       subsequently arranges permanent financing.
 
     - Expansion of Properties. The Company believes that expansion within or
       adjacent to existing AIMCO Properties also provides growth opportunities
       at lower risk than new development. Such expansion can offer cost
       advantages to the extent common area amenities and on-site management
       personnel can service the expanded property. Recently the Company
       constructed 92 additional units at Fairways, in Phoenix, Arizona, at a
       cost of $6.5 million. The Company is planning the construction of 42
       additional units at Township, in Littleton, Colorado, for a projected
       cost of more than $3.0 million. In addition, the Company owns or controls
       approximately 136 acres of vacant land, adjacent to existing Owned
       Properties or Equity Properties, which the Company believes is suitable
       for the development of approximately 1,300 apartment units. The Company
       generally finances expansions initially with borrowings from the Credit
       Facilities, and subsequently arranges permanent financing.
 
     - Conversion of Affordable Properties; Improvement of Performance. The
       Company believes that it may be able to significantly increase its return
       from its portfolio of affordable properties by improving operations at
       some of its properties or by converting some of its properties to
       conventional properties. While management of the Company has commenced
       review of the affordable properties, it has not yet made any
       determination as to the conversion of any affordable property.
 
     - Ancillary Services. The Company's management believes that its ownership
       and management of the AIMCO Properties provides it with unique access to
       a customer base for the sale of additional services which generate
       incremental revenues. The Company currently provides cable television,
       telephone services and carport, garage and storage space rental at
       certain AIMCO Properties. For example, as of June 30, 1998, the Company
       has installed cable television service to 12,600 units and currently has
       more than 7,400 subscribers.
 
     - Controlling Expenses. Cost reductions are accomplished by exploiting
       economies of scale. As a result of the size of its portfolio and its
       creation of regional concentrations of properties, the Company has the
       ability to leverage fixed costs for general and administrative
       expenditures and certain operating functions, such as insurance,
       information technology and training, over a larger property base. For
       example, the Company's insurance subsidiary provides workers'
       compensation and employer liability insurance company-wide, without
       incurring material incremental costs as the Company's property assets
       grow.
 
     The Company also instills cost discipline in its property managers by
benchmarking their operations against the local market and other AIMCO
Properties.

PROPERTY MANAGEMENT STRATEGIES
 
   
     Divisions. The Company's property management strategy is to achieve
improvements in operating results by combining centralized financial control and
uniform operating procedures with localized property management decision making
and market knowledge. The Company's management operations are organized into
five divisions, each supervised by a Division Vice President, who has, on
average, 17 years of experience in apartment management.

(1) Includes only units and apartment communities managed by the Company as of
    October 1, 1998. Does not include 14,279 units in 100 apartment communities
    in which the Company has an ownership interest but does not manage and 2,332
    senior living units, all of which are managed as a separate portfolio.
    
 
     Customer Service. The Company believes that resident satisfaction is
directly related to the experience and training of on-site management personnel.
The Company provides on-site management trained to respond promptly to
residents' needs. To improve customer service, the Company conducts annual
resident satisfaction surveys, guarantees that material defects will be
corrected in 24 hours and refunds related rent if that commitment is not met.
 
     Personnel Policies. The Company has attempted to reduce turnover and retain
experienced personnel by establishing an employee mentoring program and
providing managers with incentive-based compensation. In addition, managing
properties for third parties, the Company believes, improves performance at
Managed Properties and Owned Properties alike by subjecting property managers to
market-based pricing and service standards.
 
     START. Properties that are behind budget or face other significant
operating difficulties receive direct supervision and intervention from START, a
team of professionals, led by Executive Vice President Steven Ira, a founder of
the Company. Members of START focus on not more than 10 to 15 properties at any
one time, which allows them to focus sharply on the subject properties. START
also oversees due diligence on acquisitions and major construction activities.
 
     Management Incentives. The Company believes that equity ownership by
management and equity- and incentive-based compensation are important factors in
attracting, retaining and motivating the most qualified and experienced
personnel and directors. The Company's goal is to align management's interests
with those of stockholders through the use of equity-based compensation plans to
direct management's efforts towards enhancing shareholder value.

     - On July 25, 1997, eleven senior managers of AIMCO purchased 1.1 million
       shares of Class A Common Stock at a price of $30 per share in exchange
       for promissory notes secured by such stock, which notes are recourse as
       to 25% of the principal owed.
 
     - AIMCO pays a majority of the compensation to its outside directors in
       Class A Common Stock.
 
   
     - AIMCO issues all stock options at the then-current market price, and
       requires that employees own Class A Common Stock before receiving their
       options. As of May 31, 1998, the number of outstanding options was
       5,235,997.
    
 
   
     On January 21, 1998, the AIMCO Operating Partnership sold an aggregate of
15,000 OP Units designated as Class I High Performance Units (the "High
Performance Units") to a joint venture formed by fourteen of the Company's
officers, and to three of AIMCO's non-employee directors for an aggregate
purchase price of $2,070,000, of which $1,980,300 was paid by the joint venture
and an aggregate of $89,700 was paid by three non-employee directors. The
purchase price of the High Performance Units was determined by the AIMCO Board
of Directors, based upon the advice of an independent valuation expert that this
purchase price represented the fair market value of the High Performance Units.
The sale of the High Performance Units was ratified by the stockholders on May
8, 1998.
    
 
     Holders of High Performance Units have no rights to receive distributions
or allocations of income or loss, or to redeem their High Performance Units
prior to the date (the "Valuation Date") that is the earlier of (i) January 1,
2001, or (ii) the date on which a change of control occurs. If, on the Valuation
Date, the cumulative Total Return of the Class A Common Stock from January 1,
1998 to the Valuation Date (the "Measurement Period") exceeds 115% of the
cumulative Total Return (as defined below) of a peer group index over the same
period, and is at least the equivalent of a 30% cumulative Total Return over
three years (the "Minimum Return"), then, on and after the Valuation Date,
holders of the 15,000 High Performance Units will be entitled to receive
distributions and allocations of income and loss from the AIMCO Operating
Partnership in the same amounts and at the same times (subject to certain
exceptions upon liquidation of the AIMCO Operating Partnership) as would holders
of a number of OP Units equal to the quotient obtained by dividing (i) the
product of (A) 15% of the amount by which the cumulative Total Return of the
Class A Common Stock over the Measurement Period exceeds the greater of 115% of
the peer group index or the Minimum Return, multiplied by (B) the weighted
average market value of the Company's equity capitalization (including Class A
Common Stock and OP Units) by (ii) the market value of one share of Class A
Common Stock on the Valuation Date. If, on the Valuation Date, the cumulative
Total Return of the Class A Common Stock does not satisfy these criteria, then,
on and after the Valuation Date, holders of the 15,000 High Performance Units
will be entitled to receive distributions and allocations of income and loss
from the AIMCO Operating Partnership in the same amounts and at the same times
(subject to certain exceptions upon a liquidation of the AIMCO Operating
Partnership) as would holders of 150 OP Units. For purposes of
 
                                       27
<PAGE>   136
 
determining the market value of Class A Common Stock or OP Units as of any date,
the average closing price of the Class A Common Stock for the 20 trading days
immediately preceding such date is used. It is expected that the Morgan Stanley
REIT Index, a capitalization-weighted index with dividends reinvested of the
most actively traded real estate investment trusts, will be used as the peer
group index for purposes of the High Performance Units.
 
     "Total Return" means, for any security and for any period, the cumulative
total return for such security over such period, as measured by (i) the sum of
(a) the cumulative amount of dividends paid in respect of such security for such
period (assuming that all cash dividends are reinvested in such security as of
the payment date for such dividend based on the security price on the dividend
payment date), and (b) an amount equal to (x) the security price at the end of
such period, minus (y) the security price at the beginning of such period,
divided by (ii) the security price at the beginning of the measurement period;
provided, however, that if the foregoing calculation results in a negative
number, the "Total Return" shall be equal to zero.
 
     Upon the occurrence of a change of control, any holder of High Performance
Units may, subject to certain restrictions, require the AIMCO Operating
Partnership to redeem all or a portion of the High Performance Units held by
such party in exchange for a cash payment per unit equal to the market value of
a share of Class A Common Stock at the time of redemption. However, in the event
that any High Performance Units are tendered for redemption, the AIMCO Operating
Partnership's obligation to pay the redemption price is subject to the prior
right of AIMCO to acquire such High Performance Units in exchange for an equal
number of shares of Class A Common Stock (subject to certain adjustments).
 
ACCOUNTING POLICIES AND DEFINITIONS
 
     The Company has the following accounting policies and definitions:
 
   
     Funds from Operations. The Board of Governors of NAREIT defines FFO as net
income (loss), computed in accordance with generally accepted accounting
principles, excluding gains and losses from debt restructuring and sales of
property, plus real estate related depreciation and amortization (excluding
amortization of financing costs), and after adjustments for unconsolidated
partnerships and joint ventures. The Company calculates FFO in a manner
consistent with the NAREIT definition, which includes adjustments for minority
interest in the AIMCO Operating Partnership, plus amortization of management
company goodwill, the non-cash deferred portion of the income tax provision for
unconsolidated subsidiaries and less the payment of dividends on perpetual
preferred stock. The Company's management believes that presentation of FFO
provides investors with industry accepted measurements which help facilitate
understanding of the Company's ability to meet required dividend payments,
capital expenditures, and principal payments on its debt. There can be no
assurance that the Company's basis of computing FFO is comparable with that of
other REITs.
    
 
   
     Capital Replacements. The Company capitalizes spending for items which
generally cost more than $250 and have a useful life of more than one year, such
as carpet replacement, new appliances, new roofs or parking lot repaving.
Capitalized spending which maintains a property is termed a "Capital
Replacement." In the experience of the Company's management, this spending is
better considered a recurring cost of preserving an asset rather than an
additional investment.
    
 
   
     Consolidation. For financial reporting purposes, the Company consolidates
the results of those corporations in which it owns a majority of the outstanding
voting stock, and those limited partnerships and limited liability companies in
which it owns both a general partnership or managing member interest and
controls investment decisions with respect to the underlying assets. The Company
generally has a 30% to 51% economic interest in such entities. Entities in which
the Company has less than a 30% economic interest or limited control are
accounted for on the equity method. The Company policy is generally to hold
Class C properties and affordable properties (substantially all of which are
Class C properties) in unconsolidated partnerships. The Company accounts for
these properties on the equity method in accordance with GAAP.
    
 
                                       28
<PAGE>   137
 
POLICIES OF THE COMPANY WITH RESPECT TO CERTAIN OTHER ACTIVITIES
 
     The following is a discussion of certain other investment objectives and
policies, financing policies and other policies of the Company. These policies
are determined by the officers and directors of AIMCO and may be amended or
revised from time to time at their discretion without a vote of AIMCO's
stockholders. As the sole general partner of the AIMCO Operating Partnership,
AIMCO also determines the investment policies of the AIMCO Operating
Partnership.
 
     Investment in Others. The Company may also participate with other entities
in property ownership, through joint ventures or other types of co-ownership.
Any such equity investment may be subject to existing mortgage financing and
other indebtedness which would have priority over the equity of the Company in
that property.
 
     Securities of or Interests in Persons Primarily Engaged in Real Estate
Activities. The Company may also acquire securities of or interests in persons
engaged in the acquisition, redevelopment and/or management of multifamily
apartment properties.
 
     Investments in Real Estate Mortgages. While the Company generally
emphasizes direct real estate investments, it may, in its discretion and subject
to the percentage ownership limitations and gross income tests necessary for
REIT qualification, invest in mortgage and other indirect real estate interests,
including securities of other real estate investment trusts. The Company has not
previously invested in mortgages or securities of other real estate investment
trusts and the Company does not presently intend to invest to a significant
extent in mortgages or securities of other real estate investment trusts.
 
     Operating and Financing Policies. The Company seeks to maintain a ratio of
EBITDA (less a provision of approximately $300 per owned apartment unit) to debt
(the "Debt Coverage Ratio") of at least 2 to 1, and to match debt maturities to
the character of the assets financed. See "-- Operating and Financial
Strategies -- Debt Financing." The Company, however, may from time to time
re-evaluate borrowing policies in light of then current economic conditions,
relative costs of debt and equity capital, market values of properties, growth
and acquisition opportunities and other factors. The Company may modify its
borrowing policy and may increase or decrease its Debt Coverage Ratio policy.
 
   
     To the extent that the AIMCO Board of Directors determines to seek
additional capital, the Company may raise such capital through additional equity
offerings, debt financing or retention of cash flow (after consideration of
provisions of the Code requiring the distribution by a REIT of a certain
percentage of taxable income and taking into account taxes that would be imposed
on undistributed taxable income), or through a combination of these sources. The
Company presently anticipates that any additional borrowings will be made
through the AIMCO Operating Partnership, although AIMCO might incur borrowings
that would be reloaned to the AIMCO Operating Partnership. The AIMCO Operating
Partnership cannot incur indebtedness that is recourse to AIMCO without AIMCO's
approval. AIMCO may approve the AIMCO Operating Partnership's incurring
additional debt that is recourse to the AIMCO Operating Partnership. Borrowings
may be unsecured or may be secured by any or all assets of AIMCO, the AIMCO
Operating Partnership, or any existing or new property and may have full or
limited recourse to all or any portion of the assets of AIMCO, the AIMCO
Operating Partnership, or any existing or new property.
    
 
     The Company has not established any limit on the number or amount of
mortgages that may be placed on any single property or on its portfolio as a
whole.
 
     AIMCO may also determine to issue securities senior to the Class A Common
Stock, including preferred stock and debt securities (either of which may be
convertible into capital stock or be accompanied by warrants to purchase capital
stock). The Company may also determine to finance acquisitions through the
exchange of properties or issuance of additional OP Units, shares of Class A
Common Stock or other securities.
 
   
     If the AIMCO Board of Directors determines to raise additional equity
capital, the AIMCO Board of Directors has the authority, without stockholder
approval, to issue additional shares of Class A Common Stock or other capital
stock (including securities senior to the Class A Common Stock) in any manner
(and on such terms and for such consideration) it deems appropriate, including
in exchange for property. Such
    
 
                                       29
<PAGE>   138
 
   
issuances might cause a dilution of a stockholder's investment in AIMCO. If the
AIMCO Board of Directors determines to raise additional equity capital to fund
investments by the AIMCO Operating Partnership, AIMCO will contribute such funds
to the AIMCO Operating Partnership as a contribution to capital and purchase of
additional general partnership interests. AIMCO may issue additional shares of
Class A Common Stock in connection with the acquisition of OP Units that are
tendered to the AIMCO Operating Partnership for redemption.
    
 
   
     The AIMCO Board of Directors also has the authority to cause the AIMCO
Operating Partnership to issue additional OP Units in any manner (and on such
terms and for such consideration) as it deems appropriate, including in exchange
for property. Any such new OP Units will be redeemable at the option of the
holder, which redemption AIMCO intends to cause to be made in Class A Common
Stock pursuant to the redemption rights.
    
 
     Conflict of Interest Policies. The Company has adopted certain policies
designed to minimize or eliminate conflicts of interests between the Company and
its executive officers and directors. Without the approval of a majority of the
disinterested directors, the Company will not (i) acquire from or sell to any
director, officer or employee of the Company or any entity in which a director,
officer or employee of the Company owns more than a 1% interest, or acquire from
or sell to any affiliate of any of the foregoing, any assets or other property
of the Company, (ii) make any loan to or borrow from any of the foregoing
persons, or (iii) engage in any material transaction with the foregoing. In
addition, the Company has entered in to employment agreements with Messrs.
Considine, Kompaniez and Ira which include provisions intended to eliminate or
minimize potential conflicts of interest, and which provide that those persons
will be prohibited from engaging directly or indirectly in the acquisition,
development, operation or management of other multifamily apartment properties
outside of the Company, except with respect to certain investments currently
held by such persons, as to which investments those persons have committed to an
orderly liquidation. There can be no assurance, however, that these policies
always will be successful in eliminating the influence of such conflicts, and if
they are not successful, decisions could be made that might fail to reflect
fully the interests of AIMCO's stockholders as a whole.
 
     Policies with Respect to Other Activities. The Company has authority to
offer shares of its capital stock or other securities and to repurchase or
otherwise reacquire its shares or any other securities, has done so, and may
engage in such activities in the future. From its inception, the Company has
made loans aggregating $5.1 million to certain entities owning properties
subsequently acquired by the Company. No balances remain outstanding on such
loans. In the same period, the Company has made loans aggregating $76.5 million
to its officers for the purchase of Class A Common Stock and $5.1 million to its
officers and other entities to acquire interests in subsidiaries of the Company.
The outstanding balances on such loans as of August 31, 1998 were $42.7 million
and $3.1 million, respectively. Messrs. Considine and Kompaniez have repaid in
part, using $2.0 million in proceeds distributed to them from the sale of NHP
Common Stock by AIMCO/NHP Holdings, Inc. ("ANHI") to AIMCO, outstanding
promissory notes payable by them to ANHI in an aggregate amount of $3.2 million,
which loan was made to them by ANHI to acquire their interest in ANHI. In
addition, the Company from time to time advances amounts for relocation and
other expenses. The Company has not engaged in underwriting securities of other
issuers. Each of AIMCO and the AIMCO Operating Partnership intend to make
investments in such a way that it will not be treated as an investment company
under the Investment Company Act of 1940, as amended.
 
     The Company may invest in the securities of other issuers engaged in the
ownership, acquisition or management of multifamily apartment properties for the
purpose of exercising control.
 
   
     At all times, the Company intends to make investments in such a manner as
to be consistent with the requirements of the Code for AIMCO to qualify as a
REIT unless, because of changing circumstances or changes in the Code (or in
Treasury Regulations), the AIMCO Board of Directors determines that it is no
longer in the best interest of AIMCO to qualify as a REIT.
    
 
     AIMCO, as a REIT, is required to distribute annually to holders of Class A
Common Stock at least 95% of its "REIT taxable income," which, as defined by the
Code and the Treasury Regulations, is generally equivalent to net taxable
ordinary income. AIMCO measures its economic profitability, and intends to pay
 
                                       30
<PAGE>   139
 
   
regular dividends to its stockholders, based on earnings during the relevant
period. However, the future payment of dividends by AIMCO will be at the
discretion of the AIMCO Board of Directors and will depend on numerous factors,
including AIMCO's financial condition, its capital requirements, the annual
distribution requirements under the provisions of the Code applicable to REITs
and such other factors as the AIMCO Board deems relevant.
    
 
   
YEAR 2000 COMPLIANCE
    
 
   
     The Company's management has determined that it will be necessary to modify
or replace certain accounting and operational software and hardware to enable
its computer systems to operate properly subsequent to December 31, 1999. As a
result, management has appointed a team of internal staff to research and manage
the conversion or replacement of existing systems to comply with year 2000
requirements. The team's activities are designed to ensure that there is no
adverse effect on the Company's core business operations, and that transactions
with tenants, suppliers and financial institutions are fully supported.
    
 
     The Company utilizes numerous accounting and reporting software packages
and computer hardware to conduct its business, some of which already comply with
year 2000 requirements. Management estimates that the modification or
replacement of non-compliant accounting and reporting software and hardware will
total approximately $0.3 million.
 
   
     The Company's management also believes that certain of the Owned Properties
possess operational systems (e.g. elevators, fire alarm and extinguishment
systems and security systems) which also must be modified or replaced in order
to function properly in the 21st century. Management is currently engaged in the
identification of all non-compliant operational systems, and has not yet
determined the estimated cost of replacing or modifying such systems.
    
 
   
                         DESCRIPTION OF PREFERRED STOCK
    
 
GENERAL
 
     AIMCO may issue, from time to time, shares of one or more series or classes
of Preferred Stock. The following description sets forth certain general terms
and provisions of the Preferred Stock to which any Prospectus Supplement may
relate. The particular terms of any series of Preferred Stock that may be issued
and sold pursuant hereto, and the extent, if any, to which such general
provisions may apply to the series of Preferred Stock so offered will be
described in the Prospectus Supplement relating to such Preferred Stock. The
following summary of certain provisions of the Preferred Stock do not purport to
be complete and is subject to, and is qualified in its entirety by express
reference to, the provisions of the Charter relating to a specific series of the
Preferred Stock, which will be in the form filed as an exhibit to or
incorporated by reference in the Registration Statement of which this Prospectus
is a part at or prior to the time of issuance of such series of Preferred Stock.
 
   
     The Charter authorizes the issuance of up to 510,750,000 shares of its
capital Stock. As of August 31, 1998, 486,027,500 shares were classified as
Class A Common Stock, 262,500 shares were classified as Class B Common Stock,
750,000 shares were classified as Class B Cumulative Convertible Preferred
Stock, par value $.01 per share ("Class B Preferred Stock"), 2,760,000 shares
were classified as Class C Cumulative Preferred Stock, par value $.01 per share
("Class C Preferred Stock"), 4,600,000 shares were classified as Class D
Cumulative Preferred Stock, par value $.01 per share ("Class D Preferred
Stock"), 10,000,000 shares were classified as Class E Cumulative Preferred
Stock, par value $.01 per share ("Class E Preferred Stock"), 4,050,000 shares
were classified as Class G Cumulative Preferred Stock, par value $.01 per share
("Class G Preferred Stock"), and 2,300,000 shares were classified as Class H
Cumulative Preferred Stock, par value $.01 per share ("Class H Preferred
Stock"). Under the Charter, the AIMCO Board of Directors has the authority to
classify and reclassify any of its unissued capital Stock into shares of
Preferred Stock by setting or changing in any one or more respects the
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications or terms or conditions of redemption
of such shares of capital Stock including, but not limited to, ownership
restrictions consistent with the Ownership Limit with respect to each
    
 
                                       31
<PAGE>   140
 
series or class of capital Stock, and the number of shares constituting each
series or class, and to increase or decrease the number of shares of any such
series or class, to the extent permitted by the Maryland General Corporation Law
(the "MGCL").
 
   
     The AIMCO Board of Directors is authorized to determine for each series of
Preferred Stock, and the Prospectus Supplement will set forth with respect to
each class or series that may be issued and sold pursuant hereto: (i) the
designation of such shares and the number of shares that constitute such series,
(ii) the dividend rate (or the method of calculation thereof), if any, on the
shares of such series and the priority as to payment of dividends with respect
to other classes or series of capital stock of AIMCO, (iii) the dividend periods
(or the method of calculation thereof), (iv) the voting rights of the shares,
(v) the liquidation preference and the priority as to payment of such
liquidation preference with respect to other classes or series of capital stock
of AIMCO and any other rights of the shares of such series upon any liquidation
or winding-up of AIMCO, (vi) whether or not and on what terms the shares of such
series will be subject to redemption or repurchase at the option of AIMCO, (vii)
whether and on what terms the shares of such series will be convertible into or
exchangeable for other debt or equity securities of AIMCO, (viii) whether the
shares of such series of Preferred Stock will be listed on a securities
exchange, (ix) any special United States federal income tax considerations
applicable to such series, and (x) the other rights and privileges and any
qualifications, limitations or restrictions of such rights or privileges of such
series not inconsistent with the Charter and the MGCL.
    
 
DIVIDENDS
 
   
     Holders of shares of Preferred Stock, shall be entitled to receive, when
and as declared by the AIMCO Board of Directors, out of funds of AIMCO legally
available therefor, an annual cash dividend payable at such dates and at such
rates, if any, per share per annum as set forth in the applicable Prospectus
Supplement.
    
 
     Each series of Preferred Stock that may be issued and sold pursuant hereto,
will rank junior as to dividends to any Preferred Stock that may be issued in
the future that is expressly senior as to dividends to the Preferred Stock. If
at any time AIMCO has failed to pay accrued dividends on any such senior shares
at the time such dividends are payable, AIMCO may not pay any dividend on the
Preferred Stock or redeem or otherwise repurchase shares of Preferred Stock
until such accumulated but unpaid dividends on such senior shares have been paid
or set aside for payment in full by AIMCO.
 
     No dividends (other than in Class A Common Stock or Class B Common Stock
(collectively, the "Common Stock") or other capital Stock ranking junior to the
Preferred Stock of any series as to dividends and upon liquidation) shall be
declared or paid or set aside for payment, nor shall any other distribution be
declared or made upon the Common Stock, or any other capital stock of AIMCO
ranking junior to or on a parity with the Preferred Stock of such series as to
dividends, nor shall any Common Stock or any other capital stock of AIMCO
ranking junior to or on a parity with the Preferred Stock of such series as to
dividends or upon liquidation be redeemed, purchased or otherwise acquired for
any consideration (or any moneys be paid to or made available for a sinking fund
for the redemption of any shares of any such stock) by AIMCO (except by
conversion into or exchange for other capital stock of AIMCO ranking junior to
the Preferred Stock of such series as to dividends and upon liquidation) unless
(i) if such series of Preferred Stock has a cumulative dividend, full cumulative
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for all past dividend periods and the then current dividend period and
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for the then current dividend period; provided, however,
that any monies theretofore deposited in any sinking fund with respect to any
Preferred Stock in compliance with the provisions of such sinking fund may
thereafter be applied to the purchase or redemption of such Preferred Stock in
accordance with the terms of such sinking fund, regardless of whether at the
time of such application full cumulative dividends upon shares of the Preferred
Stock outstanding on the last dividend payment date shall have been paid or
declared and set apart for payment; and provided, further, that any such junior
or parity preferred stock or Common
 
                                       32
<PAGE>   141
 
Stock may be converted into or exchanged for stock of AIMCO ranking junior to
the Preferred Stock as to dividends.
 
     The amount of dividends payable for the initial dividend period or any
period shorter than a full dividend period shall be computed on the basis of a
360-day year of twelve 30-day months. Accrued but unpaid dividends will not bear
interest.
 
CONVERTIBILITY
 
     The applicable Prospectus Supplement for each series of Preferred Stock
that may be issued and sold pursuant hereto will set forth the terms and
conditions of such series of Preferred Stock with respect to whether such series
of Preferred Stock will be convertible into, or exchangeable for, other
securities or property, including the initial conversion or exchange rate and
any adjustments thereto, the conversion or exchange period and any other
conversion or exchange provisions.
 
REDEMPTION AND SINKING FUND
 
     The applicable Prospectus Supplement for each series of Preferred Stock
that may be issued and sold pursuant hereto will set forth the terms and
conditions of such series of Preferred Stock with respect to redemption rights
and the benefit of any sinking fund, including the dates and redemption prices
of any such redemption, any conditions thereto, and any other redemption or
sinking fund provisions.
 
LIQUIDATION RIGHTS
 
     In the event of any liquidation, dissolution or winding up of AIMCO, the
holders of shares of each series of Preferred Stock that may be issued and sold
pursuant hereto are entitled to receive out of assets of AIMCO available for
distribution to stockholders, before any distribution of assets is made to
holders of: (i) any other shares of Preferred Stock ranking junior to such
series of Preferred Stock as to rights upon liquidation, dissolution or winding
up; and (ii) shares of Common Stock, liquidating distributions per share in the
amount of the liquidation preference specified in the applicable Prospectus
Supplement for such series of Preferred Stock plus any dividends accrued and
accumulated but unpaid to the date of final distribution; but the holders of
each series of Preferred Stock will not be entitled to receive the liquidating
distribution of, plus such dividends on, such shares until the liquidation
preference of any shares of AIMCO's capital stock ranking senior to such series
of the Preferred Stock as to the rights upon liquidation, dissolution or winding
up shall have been paid (or a sum set aside therefor sufficient to provide for
payment) in full. If upon any liquidation, dissolution or winding up of AIMCO,
the amounts payable with respect to the Preferred Stock, and any other Preferred
Stock ranking as to any such distribution on a parity with the Preferred Stock
are not paid in full, the holders of the Preferred Stock and such other parity
preferred stock will share ratably in any such distribution of assets in
proportion to the full respective preferential amount to which they are
entitled. After payment of the full amount of the liquidating distribution to
which they are entitled, the holders of shares of Preferred Stock will not be
entitled to any further participation in any distribution of assets by AIMCO.
Neither a consolidation or merger of AIMCO with another corporation nor a sale
of securities shall be considered a liquidation, dissolution or winding up of
AIMCO.
 
VOTING RIGHTS
 
     Holders of Preferred Stock that may be issued and sold pursuant hereto will
have the voting rights required by law and the voting rights described below.
Whenever dividends on any applicable series of Preferred Stock or any other
class or series of stock ranking on a parity with the applicable series of
Preferred Stock with respect to the payment of dividends shall be in arrears for
the equivalent of six quarterly dividend periods, whether or not consecutive,
the holders of shares of such series of Preferred Stock (voting separately as a
class with all other series of Preferred Stock then entitled to such voting
rights) will be entitled to vote for the election of two of the authorized
number of directors of AIMCO at the next annual meeting of stockholders and at
each subsequent meeting until all dividends accumulated on such series of
Preferred Stock shall have been fully paid or set apart for payment. The term of
office of all directors elected by the holders of
 
                                       33
<PAGE>   142
 
such Preferred Stock shall terminate immediately upon the termination of the
right of the holders of such Preferred Stock to vote for directors. Holders of
shares of Preferred Stock that may be issued and sold pursuant hereto will have
one vote for each share held.
 
     So long as any shares of any series of Preferred Stock remain outstanding,
AIMCO shall not, without the consent of holders of at least two-thirds of the
shares of such series of Preferred Stock outstanding at the time, voting
separately as a class with all other series of Preferred Stock of AIMCO upon
which like voting rights have been conferred and are exercisable, (i) issue or
increase the authorized amount of any class or series of stock ranking prior to
the outstanding Preferred Stock as to dividends or upon liquidation or (ii)
amend, alter or repeal the provisions of the Charter relating to such series of
Preferred Stock, whether by merger, consolidation or otherwise, so as to
materially adversely affect any power, preference or special right of such
series of Preferred Stock or the holders thereof; provided, however, that any
increase in the amount of the authorized Common Stock or authorized Preferred
Stock or any increase or decrease in the number of shares of any series of
Preferred Stock or the creation and issuance of other series of Common Stock or
Preferred Stock ranking on a parity with or junior to Preferred Stock as to
dividends and upon liquidation, dissolution or winding up shall not be deemed to
materially adversely affect such powers, preferences or special rights.
 
MISCELLANEOUS
 
     The holders of Preferred Stock will have no preemptive rights. The
Preferred Stock that may be issued and sold pursuant hereto, upon issuance
against full payment of the purchase price therefor, will be fully paid and
nonassessable. Shares of Preferred Stock redeemed or otherwise reacquired by
AIMCO shall resume the status of authorized and unissued shares of Preferred
Stock undesignated as to series, and shall be available for subsequent issuance.
The applicable Prospectus Supplement will set forth the restrictions, if any, on
repurchase or redemption of the Preferred Stock while there is any arrearage on
sinking fund installments. Payment of dividends on, and the redemption or
repurchase of, any series of Preferred Stock may be restricted by loan
agreements, indentures and other agreements entered into by AIMCO. The
applicable Prospectus Supplement will describe any material contractual
restrictions on such dividend payments.
 
OTHER RIGHTS
 
     The shares of a series of Preferred Stock that may be issued and sold
pursuant hereto will have the preferences, voting powers or relative,
participating, optional or other special rights set forth above or in the
applicable Prospectus Supplement or the Charter or as otherwise required by law.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for each series of Preferred Stock that
may be issued and sold pursuant hereto will be designated in the applicable
Prospectus Supplement.
 
CLASS B PREFERRED STOCK
 
   
     On August 4, 1997, AIMCO issued 750,000 shares of its Class B Preferred
Stock to an institutional investor (the "Preferred Share Investor") in a private
transaction. The Class B Preferred Stock (a) ranks prior to the Common Stock and
the Class E Preferred Stock with respect to dividends, liquidation, dissolution
and winding-up, and has an aggregate liquidation value of $75 million and (b)
ranks on parity with the Class C Preferred Stock, the Class D Preferred Stock,
the Class G Preferred Stock and the Class H Preferred Stock. Holders of the
Class B Preferred Stock are entitled to receive, when, as and if declared by the
AIMCO Board of Directors, quarterly cash dividends per share equal to the
greater of (i) $1.78125 (the "Base Rate") and (ii) the cash dividends declared
on the number of shares of Class A Common Stock into which one share of Class B
Preferred Stock is convertible. On or after August 4, 1998, each share of Class
B Preferred Stock may be converted at the option of the holder into 3.28407
shares of Class A Common Stock, subject to certain anti-dilution adjustments.
AIMCO may redeem any or all of the Class B Preferred Stock on or after August 4,
2002, at a redemption price of $100 per share, plus unpaid dividends accrued on
the shares redeemed.
    
 
                                       34
<PAGE>   143
 
   
     Holders of Class B Preferred Stock, voting as a class with the holders of
all AIMCO capital stock that ranks on a parity with the Class B Preferred Stock
with respect to the payment of dividends or upon liquidation, dissolution,
winding up or otherwise ("Class B Parity Stock"), will be entitled to elect (i)
two directors of AIMCO if six quarterly dividends (regardless of whether
consecutive) on the Class B Preferred Stock or any Class B Parity Stock are in
arrears, and (ii) one director of AIMCO if for two consecutive quarterly
dividend periods AIMCO fails to pay at least $0.4625 in dividends on the Class A
Common Stock. The affirmative vote of the holders of two-thirds of the
outstanding shares of Class B Preferred Stock will be required to amend the
Charter in any manner that would adversely affect the rights of the holders of
Class B Preferred Stock, and to approve the issuance of any capital stock that
ranks senior to the Class B Preferred Stock with respect to payment of dividends
or upon liquidation, dissolution, winding up or otherwise. If the IRS were to
make a final determination that AIMCO does not qualify as a REIT in accordance
with Sections 856 through 860 of the Internal Revenue Code, the Base Rate for
the quarterly cash dividends on the Class B Preferred Stock would increase to
$3.03125 per share.
    
 
   
     The agreement pursuant to which AIMCO issued the Class B Preferred Stock
(the "Preferred Share Purchase Agreement") provides that the Preferred Share
Investor may require AIMCO to repurchase such investor's Class B Preferred Stock
in whole or in part at a price of 105% of the liquidation preference thereof,
plus accrued and unpaid dividends on the purchased shares, if (i) AIMCO shall
fail to continue to be taxed as a REIT pursuant to Sections 856 through 860 of
the Internal Revenue Code, or (ii) upon the occurrence of a change of control
(as defined in the Preferred Share Purchase Agreement). The Preferred Share
Purchase Agreement also provides that, so long as the Preferred Share Investor
owns Class B Preferred Stock with an aggregate liquidation preference of at
least $18.75 million, neither AIMCO, the AIMCO Operating Partnership nor any
subsidiary of AIMCO may issue preferred securities or incur indebtedness for
borrowed money if immediately following such issuance and after giving effect
thereto and the application of the net proceeds therefrom, AIMCO's ratio of
aggregate consolidated earnings before interest, taxes, depreciation and
amortization to aggregate consolidated fixed charges for the four fiscal
quarters immediately preceding such issuance would be less than 1.5 to 1.
    
 
   
     Subject to certain exceptions specified in the provisions of the Charter
establishing the terms of the Class B Preferred Stock, no holder may own, or be
deemed to own by virtue of various attribution and constructive ownership
provisions of the Internal Revenue Code and Rule 13d-3 under the Securities
Exchange Act of 1934, shares of Class B Preferred Stock with a value in excess
of the amount by which (i) 8.7% (or 15% in the case of certain pension trusts
described in the Internal Revenue Code, investment companies registered under
the Investment Company Act of 1940 and Mr. Considine) of the aggregate value of
all shares of capital stock of AIMCO exceeds (ii) the aggregate value of all
shares of capital stock of AIMCO, other than Class B Preferred Stock, that are
owned by such holder (the "Class B Preferred Ownership Limit"). The AIMCO Board
of Directors may waive such ownership limit if evidence satisfactory to the
AIMCO Board and AIMCO's tax counsel is presented that such ownership will not
then or in the future jeopardize AIMCO's status as a REIT. As a condition of
such waiver, the AIMCO Board of Directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class B Preferred Stock in
excess of the Class B Preferred Ownership Limit, or shares of Class B Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Internal Revenue Code, or which would otherwise result in
AIMCO failing to qualify as a REIT, are issued or transferred to any person,
such issuance or transfer will be null and void to the intended transferee, and
the intended transferee would acquire no rights to the stock. Shares of Class B
Preferred Stock transferred in excess of the Class B Preferred Ownership Limit
or other applicable limitations will automatically be transferred to a trust for
the exclusive benefit of one or more qualifying charitable organizations to be
designated by AIMCO. Shares transferred to such trust will remain outstanding,
and the trustee of the trust will have all voting and dividend rights pertaining
to such shares. The trustee of such trust may transfer such shares to a person
whose ownership of such shares does not violate the Class B Preferred Ownership
Limit or other applicable limitation. Upon a sale of such shares by the trustee,
the interest of the charitable beneficiary will terminate, and the sales
proceeds would be paid, first, to the original intended transferee, to the
extent of the lesser of (a) such transferee's original purchase price (or the
original market value of such shares if purportedly acquired by gift or devise)
and (b) the price received by
    
 
                                       35
<PAGE>   144
 
the trustee, and, second, any remainder to the charitable beneficiary. In
addition, shares of stock held in such trust are purchasable by AIMCO for a
90-day period at a price equal to the lesser of the price paid for the stock by
the original intended transferee (or the original market value of such shares if
purportedly acquired by gift or devise) and the market price for the stock on
the date that AIMCO determines to purchase the stock. The 90-day period
commences on the date of the violative transfer or the date that the AIMCO Board
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class B Preferred Stock bear a
legend referring to the restrictions described above.
 
CLASS C PREFERRED STOCK
 
   
     On December 23, 1997, AIMCO issued 2,400,000 shares of its 9% Class C
Preferred Stock in an underwritten public offering for net proceeds of
approximately $57.9 million. The Class C Preferred Stock (a) ranks prior to the
Common Stock, the Class E Preferred Stock and any other class or series of
capital stock of AIMCO if the holders of the Class C Preferred Stock are
entitled to the receipt of dividends and of amounts distributable upon
liquidation, dissolution, and winding-up in preference or priority to the
holders of shares of such class or series ("Class C Junior Stock"), (b) ranks on
parity with the Class B Preferred Stock, the Class D Preferred Stock, the Class
G Preferred Stock and the Class H Preferred Stock, and with any other class or
series of capital stock of AIMCO if the holders of such class of stock or series
and the Class C Preferred Stock shall be entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class C Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series shall be entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding up in preference or priority to the holders of the Class C Preferred
Stock ("Class C Senior Stock").
    
 
     Holders of Class C Preferred Stock are entitled to receive cash dividends
at the rate of 9% per annum of the $25 liquidation preference (equivalent to
$2.25 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year. Upon any liquidation, dissolution or
winding up of AIMCO, before payment or distribution by AIMCO shall be made to or
set apart for the holders of any shares of Class C Junior Stock, the holders of
Class C Preferred Stock shall be entitled to receive a liquidation preference of
$25 per share (the "Class C Liquidation Preference"), plus an amount equal to
all accumulated, accrued and unpaid dividends to the date of final distribution
to such holders; but such holders shall not be entitled to any further payment.
If proceeds available for distribution shall be insufficient to pay the
preference described above and any liquidating payments on any other shares of
any class or series of Class C Parity Stock, then such proceeds shall be
distributed among the holders of Class C Preferred Stock and any such other
Class C Parity Stock ratably in the same proportion as the respective amounts
that would be payable on such Class C Preferred Stock and any such other Class C
Parity Stock if all amounts payable thereon were paid in full.
 
     On and after December 23, 2002, AIMCO may redeem shares of Class C
Preferred Stock, in whole or in part, at a cash redemption price equal to 100%
of the Class C Liquidation Preference plus all accrued and unpaid dividends to
the date fixed for redemption. The Class C Preferred Stock has no stated
maturity and will not be subject to any sinking find or mandatory redemption
provisions.
 
     Holders of shares of Class C Preferred Stock have no voting rights, except
that if distributions on Class C Preferred Stock or any series or class of Class
C Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class C Preferred Stock (voting together as a single class with all
other shares of Class C Parity Stock which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class C Preferred Stock called for such purpose. The
affirmative vote of the holders of two thirds of the outstanding shares of Class
C Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class C Preferred Stock, and to
approve the issuance of any capital Stock that ranks senior to the Class C
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
                                       36
<PAGE>   145
 
   
     There are ownership restrictions applicable to the Class C Preferred Stock
that are similar to those for the Class B Preferred Stock.
    
 
   
CLASS D PREFERRED STOCK
    
 
   
     On February 19, 1998, AIMCO issued 4,200,000 shares of its 8 3/4% Class D
Preferred Stock, in an underwritten public offering, for net proceeds of
approximately $101.5 million. The Class D Preferred Stock (a) ranks prior to the
Common Stock, the Class E Preferred Stock, and any other class or series of
capital stock of AIMCO if the holders of the Class D Preferred Stock are to be
entitled to the receipt of dividends of or amounts distributable upon
liquidation, dissolution, and winding-up in preference or priority to the
holders of shares of such class or series ("Class D Junior Stock"), (b) ranks on
parity with the Class B Preferred Stock, the Class C Preferred Stock, the Class
G Preferred Stock and the Class H Preferred Stock, and with any other class or
series of capital stock of AIMCO if the holders of such class of stock or series
and the Class D Preferred Stock shall be entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class D Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series shall be entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding up in preference or priority to the holders of the Class D Preferred
Stock ("Class D Senior Stock").
    
 
     Holders of Class D Preferred Stock are entitled to receive cash dividends
at the rate of 8 3/4% per annum of the $25 liquidation preference (equivalent to
$2.1875 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year. Upon any liquidation, dissolution or
winding up of AIMCO, before payment or distribution by AIMCO shall be made to or
set apart for the holders of any shares of Class D Junior Stock, the holders of
Class D Preferred Stock shall be entitled to receive a liquidation preference of
$25 per share (the "Class D Liquidation Preference"), plus an amount equal to
all accumulated, accrued and unpaid dividends to the date of final distribution
to such holders; but such holders shall not be entitled to any further payment.
If proceeds available for distribution shall be insufficient to pay the
preference described above and any liquidating payments on any other shares of
any class or series of Class D Parity Stock, then such proceeds shall be
distributed among the holders of Class D Preferred Stock and any such other
Class D Parity Stock ratably in the same proportion as the respective amounts
that would be payable on such Class D Preferred Stock and any such other Class D
Parity Stock if all amounts payable thereon were paid in full.
 
     On and after February 19, 2003, AIMCO may redeem shares of Class D
Preferred Stock, in whole or in part, at a cash redemption price equal to 100%
of the Class D Liquidation Preference plus all accrued and unpaid dividends to
the date fixed for redemption. The Class D Preferred Stock has no stated
maturity and will not be subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class D Preferred Stock have no voting rights, except
that if distributions on Class D Preferred Stock or any series or class of Class
D Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class D Preferred Stock (voting together as a single class with all
other shares of Class D Parity Stock which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class D Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
D Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class D Preferred Stock, and to
approve the issuance of any capital stock that ranks senior to the Class D
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
   
     There are ownership restrictions applicable to the Class D Preferred Stock
that are similar to those for the Class B Preferred Stock.

CLASS E PREFERRED STOCK
 
   
     On October 1, 1998, Insignia Financial Group, Inc. was merged into AIMCO.
As merger consideration, AIMCO will issue to former Insignia stockholders up to
8,945,921 shares of Class E Preferred Stock. The Class E Preferred Stock (a)
ranks prior to Common Stock, and any other class or series of capital stock of
AIMCO if holders of the Class E Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class E Junior Stock"), (b) ranks on a parity with any class or
series of capital stock of AIMCO if the holders of such class or series of stock
and the Class E Preferred Stock shall be entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class E Parity Stock") and (c) ranks junior to the Class B Preferred Stock,
the Class C Preferred Stock, the Class D Preferred Stock, the Class G Preferred
Stock, the Class H Preferred Stock and any other class or series of capital
stock of AIMCO if the holders of such class or series shall be entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding up in preference or priority to the holders of the Class E Preferred
Stock ("Class E Senior Stock").
    
 
     On any date (each, a "Dividend Payment Date") on which cash dividends are
paid on the Class A Common Stock prior to the Class E Conversion Date (as
defined below), holders of Class E Preferred Stock are entitled to receive cash
dividends payable in an amount per share of Class E Preferred Stock equal to the
per share dividend payable on Class A Common Stock on such Dividend Payment
Date. Such dividends shall be cumulative from the date of original issue, and
shall be payable quarterly in arrears on the Dividend Payment Dates, commencing
on the first Dividend Payment Date after the date of original issue. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class E
Junior Stock, the holders of Class E Preferred Stock shall be entitled to
receive a liquidation preference of $1 per share plus the Special Dividend if
such dividend is unpaid on the date of the final distribution to such holders
(collectively, the "Class E Liquidation Preference"), and thereafter each share
of Class E Preferred Stock shall have the same rights with respect to assets of
AIMCO as one share of Class A Common Stock.
 
     On or after the twentieth anniversary of the Effective Time, AIMCO may
redeem shares of Class E Preferred Stock, in whole or in part, at a cash
redemption price equal to the sum of (i) the greater of (A) the Current Market
Price (as defined below) of the Class A Common Stock on the date specified for
redemption by AIMCO in a notice sent to holders of Class E Preferred Stock (the
"Class E Call Date") or (B) the AIMCO Index Price, but determined without giving
effect to the limitation of $38.00 per share, plus (ii) all accrued and unpaid
dividends to the Call Date. The Class E Preferred Stock has no stated maturity
and will not be subject to any sinking fund or mandatory redemption provisions.
 
     "Current Market Price" per share of Class A Common Stock on any date means
the average of the daily market prices of a share of Class A Common Stock for
the five consecutive trading days preceding such date. The market price for each
such day shall mean the last sale price, regular way, or, in case no such sale
takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the NYSE or, if the Class A Common Stock is not listed or admitted to
trading on the NYSE, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Class A Common Stock is listed or admitted to
trading or, if the Class A Common Stock is not listed or admitted to trading on
any national securities exchange, the last quoted price, or if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported by the National Association of Securities Dealers, Inc. Automated
Quotation System or, if such system is no longer in use, the principal other
automated quotations system that may then be in use or, if the Class A Common
Stock is not quoted by any such organization, the average of the closing bid and
asked prices as furnished by a professional market maker making a market in the
Class A Common Stock selected by the AIMCO Board.

<PAGE>   147
 
   
     Holders of shares of Class E Preferred Stock are entitled to one-half
( 1/2) of one vote with respect to all matters in which holders of Class A
Common Stock are entitled to vote thereon. In addition, if any portion of the
Special Dividend has yet to be declared and paid to the holders of Class E
Preferred Stock on January 15, 1999, or if distributions on Class E Preferred
Stock or any series or class of Parity Stock shall be in arrears for six or more
quarterly periods, the number of directors constituting the AIMCO Board shall be
increased by two and the holders of Class E Preferred Stock (voting together as
a single class with all other shares of Class E Parity Stock which are entitled
to similar voting rights) will be entitled to vote for the election of such
additional directors. Such right shall continue until full cumulative dividends
for all past dividend periods on all shares of Preferred Stock, including any
shares of Class E Preferred Stock, have been paid or declared and set apart for
payment.
    
 
   
     On any date which the Special Dividend, or any portion thereof, is paid
(which may be declared by the AIMCO Board in its sole discretion), the holders
of Class E Preferred Stock shall be entitled to receive an amount per share of
Class E Preferred Stock equal to the Special Dividend divided by the Series E
Conversion Ratio (as defined in the Insignia Merger Agreement). After January
15, 1999, if any portion of the Special Dividend or any other dividend has yet
to be declared and paid to the holders of Class E Preferred Stock, no dividends
may be declared or paid or set apart for payment by AIMCO on its Common Stock.
    
 
     On the close of business on the day on which the Special Dividend (or any
remaining unpaid portion thereof) is paid to the holders of the Class E
Preferred Stock, each share of Class E Preferred Stock will be automatically
converted into one share of Class A Common Stock without any action on the part
of AIMCO or the holder of such share (the "Class E Conversion Date"). If AIMCO
at any time following the Effective Time pays a dividend or makes a
distribution, subdivides, combines, reclassifies, issues rights, options or
warrants or makes any other distribution in securities in relation to its
outstanding Class A Common Stock, then AIMCO will contemporaneously do the same
with respect to the Class E Preferred Stock.
 
CLASS G PREFERRED STOCK
 
   
     On July 15, 1998, AIMCO issued 4,050,000 shares of its Class G Preferred
Stock, in an underwritten public offering for net proceeds of approximately
$98.0 million. The Class G Preferred Stock (a) ranks prior to the Common Stock,
the Class E Preferred Stock and any other class or series of capital Stock of
AIMCO, if the holders of the Class G Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class G Junior Stock"), (b) ranks on parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock and
the Class H Preferred Stock and with any other class or series of capital Stock
of AIMCO, if the holders of such class of Stock or series and the Class G
Preferred Stock shall be entitled to the receipt of dividends and of amounts
distributable upon liquidation, dissolution or winding-up in proportion to their
respective amounts of accrued and unpaid dividends per share or liquidation
preferences, without preference or priority one over the other ("Class G Parity
Stock") and (c) ranks junior to any class or series of capital Stock of AIMCO if
the holders of such class or series shall be entitled to the receipt of
dividends or amounts distributable upon liquidation, dissolution or winding-up
in preference or priority to the holders of the Class G Preferred Stock ("Class
G Senior Stock").
    
 
     Holders of Class G Preferred Stock are entitled to receive cash dividends
at the rate of 9 3/8% per annum of the $25 liquidation preference (equivalent to
$2.34375 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing October 15, 1998. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class G
Junior Stock, the holders of Class G Preferred Stock shall be entitled to
receive a liquidation preference of $25 per share (the "Class G Liquidation
Preference"), plus an amount equal to all accumulated, accrued and unpaid
dividends to the date of final distribution to such holders; but such holders
shall not be entitled to any further payment. If proceeds available for
distribution shall be insufficient to pay the preference described above and any
liquidating payments on any other shares of any class or series of Class G
Parity Stock, then such proceeds shall be distributed among the holders of Class
G Preferred Stock and any such other Class G Parity Stock ratably in the same
proportion as the respective amount that would be payable on
 
                                       39
<PAGE>   148
 
such Class G Preferred Stock and any such other Class G Parity Stock if all
amounts payable thereon were paid in full.
 
     On and after July 15, 2008, AIMCO may redeem shares of Class G Preferred
Stock, in whole or in part, at a cash redemption price equal to 100% of the
Class G Liquidation Preference plus all accrued and unpaid dividends to the date
fixed for redemption. The Class G Preferred Stock has no stated maturity and
will not be subject to any sinking fund or mandatory redemption provisions.
 
     Holders of shares of Class G Preferred Stock have no voting rights, except
that if distributions on Class G Preferred Stock or any series or class of Class
G Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class G Preferred Stock (voting together as a single class with all
other shares of Class G Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class G Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
G Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class G Preferred Stock, and to
approve the issuance of any capital Stock that ranks senior to the Class G
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
   
     There are ownership restrictions applicable to the Class G Preferred Stock
that are similar to those for the Class B Preferred Stock.
    
 
CLASS H PREFERRED STOCK
 
   
     On August 11, 1998, AIMCO issued 2,000,000 shares of its Class H Preferred
Stock, in an underwritten public offering for net proceeds of approximately
$48.1 million. The Class H Preferred Stock (a) ranks prior to the Common Stock,
the Class E Preferred Stock and any other class or series of capital Stock of
AIMCO if the holders of the Class H Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class H Junior Stock"), (b) ranks on parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock and
the Class G Preferred Stock, and with any other class or series of capital Stock
of AIMCO, if the holders of such class of Stock or series and the Class G
Preferred Stock shall be entitled to the receipt of dividends and of amounts
distributable upon liquidation, dissolution or winding-up in proportion to their
respective amounts of accrued and unpaid dividends per share or liquidation
preferences, without preference or priority one over the other ("Class H Parity
Stock") and (c) ranks junior to any class or series of capital Stock of AIMCO if
the holders of such class or series shall be entitled to the receipt of
dividends or amounts distributable upon liquidation, dissolution or winding-up
in preference or priority to the holders of the Class H Preferred Stock ("Class
H Senior Stock").
    
 
     Holders of Class H Preferred Stock are entitled to receive cash dividends
at the rate of 9 1/2% per annum of the $25 liquidation preference (equivalent to
$2.375 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing October 15, 1998. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class H
Junior Stock, the holders of Class H Preferred Stock shall be entitled to
receive a liquidation preference of $25 per share (the "Class H Liquidation
Preference"), plus an amount equal to all accumulated, accrued and unpaid
dividends to the date of final distribution to such holders; but such holders
shall not be entitled to any further payment. If proceeds available for
distribution shall be insufficient to pay the preference described above and any
liquidating payments on any other shares of any class or series of Class H
Parity Stock, then such proceeds shall be distributed among the holders of Class
H Preferred Stock and any such other Class H Parity Stock ratably in the same
proportion as the respective amount that would be payable on such Class H
Preferred Stock and any such other Class H Parity Stock if all amounts payable
thereon were paid in full.

<PAGE>   149
 
     On and after August 14, 2003, AIMCO may redeem shares of Class H Preferred
Stock, in whole or in part, at a cash redemption price equal to 100% of the
Class H Liquidation Preference plus all accrued and unpaid dividends to the date
fixed for redemption. The Class H Preferred Stock has no stated maturity and
will not be subject to any sinking fund or mandatory redemption provisions.
 
     Holders of shares of Class H Preferred Stock have no voting rights, except
that if distributions on Class H Preferred Stock or any series or class of Class
H Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class H Preferred Stock (voting together as a single class with all
other shares of Class H Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class H Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
H Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class H Preferred Stock, and to
approve the issuance of any capital Stock that ranks senior to the Class H
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
   
     There are ownership restrictions applicable to the Class H Preferred Stock
that are similar to those for the Class B Preferred Stock.
    
 
                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
   
     The Charter authorizes the issuance of up to 510,750,000 shares of capital
Stock with a par value of $.01 per share, of which 486,027,500 shares were
classified as Class A Common Stock and 262,500 shares were classified as Class B
Common Stock as of October 1, 1998. As of October 1, 1998, there were 47,982,057
shares of Class A Common Stock issued and outstanding. In addition, up to
150,000 shares of Class A Common Stock have been reserved for issuance under
AIMCO's 1994 Stock Option Plan, up to 500,000 shares of Class A Common Stock
have been reserved for issuance under AIMCO's 1996 Stock Award and Incentive
Plan, and up to 500,000 shares of Class A Common Stock have been reserved for
issuance under AIMCO's Non-Qualified Stock Option Plan. Under AIMCO's 1997 Stock
Award and Incentive Plan, AIMCO may issue up to 10% of the shares of Class A
Common Stock outstanding as of the first day of the fiscal year during which any
award is made, but in no event more than 20,000,000 shares of Class A Common
Stock. The Class A Common Stock is traded on the NYSE under the symbol "AIV."
BankBoston, N.A. serves as transfer agent and registrar of the Class A Common
Stock. As of October 1, 1998, the Charter authorized 750,000 shares of Class B
Preferred Stock, all of which were issued and outstanding; 2,760,000 shares of
Class C Preferred Stock, of which 2,400,000 shares were issued and outstanding;
4,600,000 shares of Class D Preferred Stock, of which 4,200,000 shares were
issued and outstanding; 10,000,000 shares of Class E Preferred Stock, of which
up to 8,945,921 shares are expected to be issued as consideration for the
Insignia merger; 4,050,000 shares of Class G Preferred Stock, all of which
shares were issued and outstanding; and 2,300,000 shares of Class H Preferred
Stock, of which 2,000,000 shares were issued and outstanding. In addition, the
Charter authorizes 262,500 shares of Class B Common Stock, which number is
subject to reduction by the number of shares of Class B Common Stock that have
been converted into shares of Class A Common Stock. As of August 31, 1998,
162,500 shares of Class B Common Stock were issued and outstanding. See
"-- Class B Common Stock."
    
 
CLASS A COMMON STOCK
 
     Holders of the Class A Common Stock are entitled to receive dividends, when
and as declared by the AIMCO Board, out of funds legally available therefor. The
holders of shares of Class A Common Stock, upon any liquidation, dissolution or
winding up of AIMCO, are entitled to receive ratably any assets remaining after
payment in full of all liabilities of AIMCO and the liquidation preferences of
preferred stock. The shares of Class A Common Stock possess ordinary voting
rights for the election of Directors and in respect of other
 
                                       41
<PAGE>   150
 
corporate matters, each share entitling the holder thereof to one vote. Holders
of shares of Class A Common Stock do not have cumulative voting rights in the
election of Directors, which means that holders of more than 50% of the shares
of Class A Common Stock voting for the election of Directors can elect all of
the Directors if they choose to do so and the holders of the remaining shares
cannot elect any Directors. Holders of shares of Class A Common Stock do not
have preemptive rights, which means they have no right to acquire any additional
shares of Class A Common Stock that may be issued by AIMCO at a subsequent date.
 
RESTRICTIONS ON TRANSFER
 
     For AIMCO to qualify as a REIT under the Code, not more than 50% in value
of its outstanding capital stock may be owned, directly or indirectly, by five
or fewer individuals (as defined in the Code to include certain entities) during
the last half of a taxable year and the shares of capital stock must be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year of 12 months or during a proportionate part of a shorter taxable year.
Because the AIMCO Board believes that it is essential for AIMCO to continue to
qualify as a REIT and to provide additional protection for AIMCO's stockholders
in the event of certain transactions, the AIMCO Board has adopted, and the
stockholders have approved, provisions of the Charter restricting the
acquisition of shares of Common Stock.
 
   
     Subject to certain exceptions specified in the Charter, no holder may own,
or be deemed to own by virtue of various attribution and constructive ownership
provisions of the Internal Revenue Code and Rule 13d-3 under the Exchange Act,
more than 8.7% (or 15% in the case of certain pension trusts described in the
Internal Revenue Code, investment companies registered under the Investment
Company Act of 1940 and Mr. Considine) of the outstanding shares of Common
Stock. For purposes of calculating the amount of stock owned by a given
individual, the individual's Common Stock and Common OP Units are aggregated.
The AIMCO Board of Directors may waive the Ownership Limit if evidence
satisfactory to the AIMCO Board of Directors and AIMCO's tax counsel is
presented that such ownership will not then or in the future jeopardize AIMCO's
status as a REIT. However, in no event may such holder's direct or indirect
ownership of Common Stock exceed 9.8% of the total outstanding shares of Common
Stock. As a condition of such waiver, the AIMCO Board of Directors may require
opinions of counsel satisfactory to it and/or an undertaking from the applicant
with respect to preserving the REIT status of AIMCO. The foregoing restrictions
on transferability and ownership will not apply if the AIMCO Board of Directors
determines that it is no longer in the best interests of AIMCO to attempt to
qualify, or to continue to quality as a REIT and a resolution terminating
AIMCO's status as a REIT and amending the Charter to remove the foregoing
restrictions is duly adopted by the AIMCO Board of Directors and a majority of
AIMCO's stockholders. If shares of Common Stock in excess of the Ownership
Limit, or shares of Common Stock which would cause the REIT to be beneficially
owned by fewer than 100 persons, or which would result in AIMCO being "closely
held," within the meaning of Section 856(h) of the Internal Revenue Code, or
which would otherwise result in AIMCO failing to qualify as a REIT, are issued
or transferred to any person, such issuance or transfer shall be null and void
to the intended transferee, and the intended transferee would acquire no rights
to the stock. Shares of Common Stock transferred in excess of the Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Ownership Limit or other applicable limitation. Upon a sale of such shares
by the trustee, the interest of the charitable beneficiary will terminate, and
the sales proceeds would be paid, first, to the original intended transferee, to
the extent of the lesser of (a) such transferee's original purchase price (or
the original market value of such shares if purportedly acquired by gift or
devise) and (b) the price received by the trustee, and, second, any remainder to
the charitable beneficiary. In addition, shares of stock held in such trust are
purchasable by AIMCO for a 90-day period at a price equal to the lesser of the
price paid for the stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the stock on the date that AIMCO determines to purchase the
stock. The 90-day period commences on the date of the violative transfer or the
date that the AIMCO Board of Directors determines in good faith that a
    
 
                                       42
<PAGE>   151
 
violative transfer has occurred, whichever is later. All certificates
representing shares of Common Stock bear a legend referring to the restrictions
described above.
 
   
     All persons who own, directly or by virtue of the attribution provisions of
the Internal Revenue Code and Rule 13d-3 under the Securities Exchange Act of
1934, more than a specified percentage of the outstanding shares of Common Stock
must file a written statement or an affidavit with AIMCO containing the
information specified in the Charter within 30 days after January 1 of each
year. In addition, each stockholder shall upon demand be required to disclose to
AIMCO in writing such information with respect to the direct, indirect and
constructive ownership of shares as the AIMCO Board deems necessary to comply
with the provisions of the Internal Revenue Code applicable to a REIT or to
comply with the requirements of any taxing authority or governmental agency.
    
 
   
     The ownership limitations may have the effect of precluding acquisition of
control of AIMCO by a third party unless the AIMCO Board of Directors determines
that maintenance of REIT status is no longer in the best interests of AIMCO.
    
 
CLASS B COMMON STOCK
 
     In connection with the initial formation of AIMCO, Terry Considine, Peter
Kompaniez, Steven Ira and Robert P. Lacy (a former officer of AIMCO) acquired an
aggregate of 650,000 shares of Class B Common Stock. The Charter, which
initially authorized 750,000 shares of Class B Common Stock, was amended in June
1998 to authorize 262,500 shares of Class B Common Stock, of which 162,500
shares are issued and outstanding. The Class B Common Stock does not have voting
or dividend rights and, unless converted into Class A Common Stock, as described
below, is subject to repurchase by AIMCO as described below. As of December 31
of each of the years 1994 through 1998 (each, a "Year-End Testing Date"), a
number of the shares of Class B Common Stock outstanding as of such date (the
"Eligible Class B Shares") become eligible for automatic conversion (subject to
the Ownership Limit) into an equal number of shares of Class A Common Stock
(subject to adjustment upon the occurrence of certain events in respect of the
Class A Common Stock, including stock dividends, subdivisions, combinations and
reclassifications). Once Class B Common Stock has been converted into Class A
Common Stock, holders of such shares of converted Class A Common Stock will have
voting and dividend rights of Class A Common Stock generally. Once converted or
forfeited, the Class B Common Stock may not be reissued by AIMCO.
 
     The Eligible Class B Shares convert to Class A Common Stock if (i) AIMCO's
Funds from Operations Per Share (as defined below) reaches certain annual and
cumulative growth targets and (ii) the average market price for a share of Class
A Common Stock for a 90 calendar day period beginning on any day on or after the
October 1 immediately preceding the relevant Year-End Testing Date equals or
exceeds a specified target price. "Funds from Operations Per Share" or "FFO Per
Share" means, for any period, (i) net income (loss), computed in accordance with
generally accepted accounting principles, excluding gains (or losses) from debt
restructuring and sales of property, plus depreciation and amortization, and
after adjustments for unconsolidated partnerships and joint ventures, less any
preferred stock dividend payments, divided by (ii) the sum of (a) the number of

(1) Assumes that only the shares of Class B Common Stock outstanding as of
    December 31, 1997 remain outstanding until converted into shares of Class A
    Common Stock.
 
     If the annual growth target is not met for a particular Year-End Testing
Date, the Eligible Class B Shares for that date may be converted as of a
subsequent Year-End Testing Date if all of the targets are met for that
subsequent Year-End Testing Date. Any Class B Common Stock that has not been
converted into Class A Common Stock following December 31, 1998 will be subject
to repurchase by AIMCO at a price of $0.10 per share. Class B Common Stock is
also subject to automatic conversion upon the occurrence of certain events,
including a change of control (as defined in the Charter). The AIMCO Board may
increase the number of shares which are eligible for conversion as of any
Year-End Testing Date and may, under certain circumstances, accelerate the
conversion of outstanding Class B Common Stock at such time and in such amount
as it may determine appropriate.
 
     All of the 65,000 shares of Class B Common Stock eligible for conversion as
of the December 31, 1994 Year-End Testing Date, all of the 130,000 shares of
Class B Common Stock eligible for conversion as of the December 31, 1995
Year-End Testing Date, all of the 130,000 shares of Class B Common Stock
eligible for conversion as of December 31, 1996 and all of the 162,500 shares of
Class B Common Stock eligible for conversion as of December 31, 1997, have been
converted into shares of Class A Common Stock. As of December 31, 1997, the
outstanding Class B Common Stock was held as follows: 93,428 shares by Mr.
Considine, 41,438 shares by Mr. Kompaniez, 13,821 shares by Mr. Ira and 13,813
shares by Mr. Lacy.
 
BUSINESS COMBINATIONS
 
     Under the MGCL, certain "business combinations" (including a merger,
consolidation, share exchange or, in certain circumstances, an asset transfer or
issuance or reclassification of equity securities) between a Maryland
corporation and any person who beneficially owns 10% or more of the voting power
of the corporation's shares or an affiliate of the corporation who, at any time
within the two-year period prior to the date in question, was the beneficial
owner of 10% or more of the voting power of the then-outstanding voting stock of
the corporation (an "Interested Stockholder") or an affiliate thereof are
prohibited for five years after the most recent date on which the Interested
Stockholder became an Interested Stockholder. Thereafter, any such business
combination must be recommended by the board of directors of the corporation and
approved by the affirmative vote of at least (a) 80% of the votes entitled to be
cast by holders of outstanding voting shares of the corporation, voting together
as a single voting group, and (b) two-thirds of the votes entitled to be cast by
holders of outstanding voting shares of the corporation other than shares held
by the Interested Stockholder or an affiliate of the Interested Stockholder with
whom the business combination is to be effected, unless, among other conditions,
the corporation's stockholders receive a minimum price (as defined in the MGCL)
for their shares and the consideration is received in cash or in the same form
as previously paid by the Interested Stockholder for its shares. For purposes of
determining whether a person is an Interested Stockholder, ownership of Common
OP Units will be treated as beneficial ownership of the shares of Common Stock
for which the Common OP Units may be redeemed. The business combination statute
could have the effect of discouraging offers to acquire AIMCO and of increasing
the difficulty of consummating any such offer. These provisions of the MGCL do
not apply, however, to business combinations that are approved or exempted by
the board of directors of the corporation prior to the time that the Interested
Stockholder becomes an Interested Stockholder. The AIMCO Board has not passed
such a resolution.

CONTROL SHARE ACQUISITIONS
 
     The MGCL provides that "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the matter,
excluding shares of stock owned by the acquiror or by officers or directors who
are employees of the corporation. "Control shares" are voting shares of stock
that, if aggregated with all other shares of stock previously acquired by that
person, would entitle the acquiror to exercise voting power in electing
directors within one of the following ranges of voting power: (i) one-fifth or
more but less than one-third, (ii) one-third or more but less than a majority or
(iii) a majority or more of all voting power. Control shares do not include
shares the acquiring person is then entitled to vote as a result of having
previously obtained stockholder approval.
 
     A "control share acquisition" means the acquisition of control shares,
subject to certain exceptions. A person who has made or proposes to make a
control share acquisition, upon satisfaction of certain conditions (including an
undertaking to pay expenses), may compel the corporation's board of directors to
call a special meeting of stockholders, to be held within 50 days of demand, to
consider the voting rights of the shares. If no request for a meeting is made,
the corporation may itself present the question at any stockholders meeting.
 
     If voting rights are not approved at the meeting or if the acquiring person
does not deliver an "acquiring person statement" as required by the statute,
then, subject to certain conditions and limitations, the corporation may redeem
any or all of the control shares (except those for which voting rights have
previously been approved) for fair value determined, without regard to the
absence of voting rights, as of the date of the last control share acquisition
or of any meeting of stockholders at which the voting rights of such shares were
considered and not approved. If voting rights for control shares are approved at
a stockholders meeting and the acquiror becomes entitled to vote a majority of
the shares entitled to vote, all other stockholders may exercise appraisal
rights. The fair value of the shares as determined for purposes of the appraisal
rights may not be less than the highest price per share paid in the control
share acquisition, and certain limitations and restrictions otherwise applicable
to the exercise of dissenters' rights do not apply in the context of a control
share acquisition.
 
     The control share acquisition statute does not apply to shares acquired in
a merger, consolidation or share exchange if the corporation is a party to the
transaction, or to acquisitions approved or exempted by the corporation's
articles of incorporation or bylaws prior to the control share acquisition. No
such exemption appears in the Charter or in AIMCO's bylaws (the "Bylaws"). The
control share acquisition statute could have the effect of discouraging offers
to acquire AIMCO and of increasing the difficulty of consummating any such
offer.
 
                            DESCRIPTION OF OP UNITS
 
     The following description sets forth certain general terms and provisions
of the OP Units and the AIMCO Operating Partnership Agreement. The AIMCO
Operating Partnership Agreement is included as Appendix B-1 hereto, and this
description is qualified in its entirety by the terms thereof.
 
GENERAL
 
     The AIMCO Operating Partnership is a limited partnership organized pursuant
to the provisions of the Delaware Revised Uniform Limited Partnership Act (as
amended from time to time, or any successor to such statute, the "Delaware LP
Act") and upon the terms and subject to the conditions set forth in the AIMCO
Operating Partnership Agreement. AIMCO GP, a Delaware corporation and a wholly
owned subsidiary of AIMCO, is the sole general partner of the AIMCO Operating
Partnership. Another wholly owned subsidiary of AIMCO, the Special Limited
Partner, is a limited partner in the AIMCO Operating Partnership. The term of
the AIMCO Operating Partnership commenced on May 16, 1994, and will continue
until December 31, 2093, unless the AIMCO Operating Partnership is dissolved
sooner pursuant to the provisions of the AIMCO Operating Partnership Agreement
or as otherwise provided by law.
 
                                       45
<PAGE>   154
 
PURPOSE AND BUSINESS
 
     The purpose and nature of the AIMCO Operating Partnership is to conduct any
business, enterprise or activity permitted by or under the Delaware LP Act,
including, but not limited to, (i) to conduct the business of ownership,
construction, development and operation of multifamily rental apartment
communities, (ii) to enter into any partnership, joint venture, business trust
arrangement, limited liability company or other similar arrangement to engage in
any business permitted by or under the Delaware LP Act, or to own interests in
any entity engaged in any business permitted by or under the Delaware LP Act,
(iii) to conduct the business of providing property and asset management and
brokerage services, whether directly or through one or more partnerships, joint
ventures, subsidiaries, business trusts, limited liability companies or other
similar arrangements, and (iv) to do anything necessary or incidental to the
foregoing; provided, however, such business and arrangements and interests may
be limited to and conducted in such a manner as to permit AIMCO, in the sole and
absolute discretion of the AIMCO GP, at all times to be classified as a REIT.
 
MANAGEMENT BY THE AIMCO GP
 
   
     Except as otherwise expressly provided in the AIMCO Operating Partnership
Agreement, all management powers over the business and affairs of the AIMCO
Operating Partnership are exclusively vested in the AIMCO GP. None of the
limited partners of the AIMCO Operating Partnership or any other person to whom
one or more OP Units have been transferred (each, an "Assignee") will take part
in the operations, management or control (within the meaning of the Delaware LP
Act) of the AIMCO Operating Partnership's business, transact any business in the
AIMCO Operating Partnership's name or have the power to sign documents for or
otherwise bind the AIMCO Operating Partnership. The AIMCO GP may not be removed
by the partners with or without cause, except with the consent of the AIMCO GP.
In addition to the powers granted a general partner of a limited partnership
under applicable law or that are granted to the AIMCO GP under any other
provision of the AIMCO Operating Partnership Agreement, the AIMCO GP, subject to
the other provisions of the AIMCO Operating Partnership Agreement, has full
power and authority to do all things deemed necessary or desirable by it to
conduct the business of the AIMCO Operating Partnership, to exercise all powers
of the AIMCO Operating Partnership and to effectuate the purposes of the AIMCO
Operating Partnership. The AIMCO Operating Partnership may incur debt or enter
into other similar credit, guarantee, financing or refinancing arrangements for
any purpose (including, without limitation, in connection with any acquisition
of properties) upon such terms as the AIMCO GP determines to be appropriate. The
AIMCO GP is authorized to execute, deliver and perform certain agreements and
transactions on behalf of the AIMCO Operating Partnership without any further
act, approval or vote of the partners.
    
 
   
     Restrictions on AIMCO GP's Authority. The AIMCO GP may not take any action
in contravention of the AIMCO Operating Partnership Agreement. The AIMCO GP may
not, without the prior consent of the limited partners, undertake, on behalf of
the AIMCO Operating Partnership, any of the following actions or enter into any
transaction that would have the effect of such transactions: (i) except as
provided in the AIMCO Operating Partnership Agreement, amend, modify or
terminate the AIMCO Operating Partnership Agreement other than to reflect the
admission, substitution, termination or withdrawal of partners; (ii) make a
general assignment for the benefit of creditors or appoint or acquiesce in the
appointment of a custodian, receiver or trustee for all or any part of the
assets of the AIMCO Operating Partnership; (iii) institute any proceeding for
bankruptcy on behalf of the AIMCO Operating Partnership; or (iv) subject to
certain exceptions, approve or acquiesce to the transfer of the AIMCO Operating
Partnership interest of the AIMCO GP, or admit into the AIMCO Operating
Partnership any additional or successor general partners of the AIMCO Operating
Partnership.
    
 
   
     Issuance of Additional OP Limited Partnership Interests. The AIMCO GP is
authorized to admit additional limited partners to the AIMCO Operating
Partnership from time to time, on terms and conditions and for such capital
contributions as may be established by the AIMCO GP in its reasonable
discretion. The net capital contribution need not be equal for all partners. No
action or consent by the limited partners is required in connection with the
admission of any additional limited partner. The AIMCO GP is expressly
authorized to cause the AIMCO Operating Partnership to issue additional
interests (i) upon the conversion, redemption or exchange of any debt, OP Units
or other securities issued by the AIMCO Operating
    
 
                                       46
<PAGE>   155
 
   
Partnership, (ii) for less than fair market value, so long as the AIMCO GP
concludes in good faith that such issuance is in the best interests of the AIMCO
GP and the AIMCO Operating Partnership, and (iii) in connection with any merger
of any other entity into the AIMCO Operating Partnership if the applicable
merger agreement provides that persons are to receive interests in the AIMCO
Operating Partnership in exchange for their interests in the entity merging into
the AIMCO Operating Partnership. Subject to Delaware law, any additional
partnership interests may be issued in one or more classes, or one or more
series of any of such classes, with such designations, preferences and relative,
participating, optional or other special rights, powers and duties as shall be
determined by the AIMCO GP, in its sole and absolute discretion without the
approval of any limited partners, and set forth in a written document thereafter
attached to and made an exhibit to the AIMCO Operating Partnership Agreement.
Without limiting the generality of the foregoing, the AIMCO GP shall have
authority to specify (a) the allocations of items of partnership income, gain,
loss, deduction and credit to each such class or series of partnership
interests; (b) the right of each such class or series of partnership interests
to share in distributions by the AIMCO Operating Partnership; (c) the rights of
each such class or series of partnership interests upon dissolution and
liquidation of the AIMCO Operating Partnership; (d) the voting rights, if any,
of each such class or series of partnership interests; and (e) the conversion,
redemption or exchange rights applicable to each such class or series of
partnership interests. Interests in the AIMCO Operating Partnership that have
distribution rights, or rights upon liquidation, winding up or dissolution, that
are superior or prior to the Common OP Units are Preferred OP Units. No person
will be admitted as an additional limited partner without the consent of the
AIMCO GP, which consent may be given or withheld in the AIMCO GP's sole and
absolute discretion.
    
 
MANAGEMENT LIABILITY AND INDEMNIFICATION
 
   
     Notwithstanding anything to the contrary set forth in the AIMCO Operating
Partnership Agreement, the AIMCO GP is not liable to the AIMCO Operating
Partnership for losses sustained, liabilities incurred or benefits not derived
as a result of errors in judgment or mistakes of fact or law of any act or
omission if the AIMCO GP acted in good faith. The AIMCO Operating Partnership
Agreement provides for indemnification of AIMCO, or any director or officer of
AIMCO (in its capacity as the previous general partner of the AIMCO Operating
Partnership), the AIMCO GP, any officer or director of AIMCO GP or the AIMCO
Operating Partnership and such other persons as the AIMCO GP may designate from
and against all losses, claims, damages, liabilities, joint or several, expenses
(including legal fees), fines, settlements and other amounts incurred in
connection with any actions relating to the operations of the AIMCO Operating
Partnership, as set forth in the AIMCO Operating Partnership Agreement. The
Delaware LP Act provides that subject to the standards and restrictions, if any,
set forth in its partnership agreement, a limited partnership may, and shall
have the power to, indemnify and hold harmless any partner or other person from
and against any and all claims and demands whatsoever. It is the position of the
SEC that indemnification of directors and officers for liabilities arising under
the Securities Act of 1933 is against public policy and is unenforceable
pursuant to Section 14 of the Securities Act of 1933.
    
 
COMPENSATION AND FEES
 
     The AIMCO GP does not receive compensation for its services as general
partner of the AIMCO Operating Partnership. However, the AIMCO GP is entitled to
payments, allocations and distributions in its capacity as general partner of
the AIMCO Operating Partnership. In addition, the AIMCO Operating Partnership is
responsible for all expenses incurred relating to the AIMCO Operating
Partnership's ownership of its assets and the operation of the AIMCO Operating
Partnership and reimburses the AIMCO GP for such expenses paid by the AIMCO GP.
The employees of the AIMCO Operating Partnership receive compensation for their
services.
 
FIDUCIARY RESPONSIBILITIES
 
     The directors and officers of the AIMCO GP have fiduciary duties to manage
the AIMCO GP in a manner beneficial to AIMCO, as the sole stockholder of the
AIMCO GP. At the same time, the AIMCO GP, as general partner, has fiduciary
duties to manage the AIMCO Operating Partnership in a manner beneficial
 
                                       47
<PAGE>   156
 
to the AIMCO Operating Partnership and its partners. The duties of the AIMCO GP,
as general partner, to the AIMCO Operating Partnership and its partners,
therefore, may come into conflict with the duties of the directors and officers
of the AIMCO GP to its sole stockholder, AIMCO.
 
   
     Unless otherwise provided for in the relevant partnership agreement,
Delaware law generally requires a general partner of a Delaware limited
partnership to adhere to fiduciary duty standards under which it owes its
limited partners the highest duties of good faith, fairness and loyalty and
which generally prohibit such general partner from taking any action or engaging
in any transaction as to which it has a conflict of interest. The AIMCO
Operating Partnership Agreement expressly authorizes the AIMCO GP to enter into,
on behalf of the AIMCO Operating Partnership, a right of first opportunity
arrangement and other conflict avoidance agreements with various affiliates of
the AIMCO Operating Partnership and the AIMCO GP, on such terms as the AIMCO GP,
in its sole and absolute discretion, believes are advisable. The latitude given
in the AIMCO Operating Partnership Agreement to the AIMCO GP in resolving
conflicts of interest may significantly limit the ability of a limited partner
to challenge what might otherwise be a breach of fiduciary duty. The AIMCO GP
believes, however, that such latitude is necessary and appropriate to enable it
to serve as the general partner of the AIMCO Operating Partnership without undue
risk of liability.
    
 
     The AIMCO Operating Partnership Agreement expressly limits the liability of
the AIMCO GP by providing that the AIMCO GP, and its officers and directors will
not be liable or accountable in damages to the AIMCO Operating Partnership, the
limited partners or assignees for errors in judgment or mistakes of fact or law
or of any act or omission if the AIMCO GP or such director or officer acted in
good faith. In addition, the AIMCO Operating Partnership is required to
indemnify the AIMCO GP, its affiliates and their respective officers, directors,
employees and agents to the fullest extent permitted by applicable law, against
any and all losses, claims, damages, liabilities, joint or several, expenses,
judgments, fines and other actions incurred by the AIMCO GP or such other
persons, provided that the AIMCO Operating Partnership will not indemnify for
(i) willful misconduct or a knowing violation of the law or (ii) for any
transaction for which such person received an improper personal benefit in
violation or breach of any provision of the AIMCO Operating Partnership
Agreement.
 
     The provisions of Delaware law that allow the common law fiduciary duties
of a general partner to be modified by a partnership agreement have not been
resolved in a court of law, and the AIMCO GP has not obtained an opinion of
counsel covering the provisions set forth in the AIMCO Operating Partnership
Agreement that purport to waive or restrict the fiduciary duties of the AIMCO GP
that would be in effect under common law were it not for the AIMCO Operating
Partnership Agreement. See "Risk Factors -- Risks Associated With an Investment
in OP Units -- Conflicts of Interest and Fiduciary Responsibility."
 
CLASS B PARTNERSHIP PREFERRED UNITS
 
   
     On August 4, 1997, in connection with AIMCO's issuance of 750,000 shares of
Class B Preferred Stock, the AIMCO Operating Partnership issued 750,000 Class B
Partnership Preferred Units to the Special Limited Partner. The terms of the
Class B Partnership Preferred Units are substantially the same as the terms of
the Class B Preferred Stock. The Class B Partnership Preferred Units entitle the
Special Limited Partner to receive preferred quarterly cash distributions of
$1.78125 per unit or, if greater, the distributions then payable on Common OP
Units into which such Class B Partnership Preferred Units are convertible. On or
after August 4, 1998, upon the conversion of Class B Preferred Stock into Class
A Common Stock, a number of Class B Partnership Preferred Units equal to the
number of shares of Class B Preferred Stock so converted will be converted into
Common OP Units. The number of Common OP Units issued upon conversion of Class B
Partnership Preferred Units is determined by dividing the Class B Partnership
Preferred Unit's liquidation preference of $100 per unit by $30.45. In addition,
each Class B Partnership Preferred Unit has a priority in liquidation equal to
$100 per unit plus an amount equal to the accumulated, accrued and unpaid
dividends on a share of Class B Preferred Stock.
    
 
                                       48
<PAGE>   157
 
CLASS C PARTNERSHIP PREFERRED UNITS
 
   
     On December 23, 1997, in connection with AIMCO's issuance of 2,400,000
shares of Class C Preferred Stock, the AIMCO Operating Partnership issued
2,400,000 Class C Partnership Preferred Units to the Special Limited Partner.
The terms of the Class C Partnership Preferred Units are substantially the same
as the terms of the Class C Preferred Stock. The Class C Partnership Preferred
Units entitle the Special Limited Partner to receive preferred quarterly cash
distributions of $0.5625 per unit ($2.25 per annum). In addition, each Class C
Partnership Preferred Unit has a priority in liquidation equal to $25 per unit
plus an amount equal to the accumulated, accrued and unpaid dividends on a share
of Class C Preferred Stock.
    
 
CLASS D PARTNERSHIP PREFERRED UNITS
 
   
     On February 19, 1998, in connection with AIMCO's issuance of 4,200,000
shares of Class D Preferred Stock, the AIMCO Operating Partnership issued
4,200,000 Class D Partnership Preferred Units to the Special Limited Partner.
The terms of the Class D Partnership Preferred Units are substantially the same
as the terms of the Class D Preferred Stock. The Class D Partnership Preferred
Units entitle the Special Limited Partner to receive preferred quarterly cash
distributions of $0.546875 ($2.1875 per annum). In addition, each Class D
Partnership Preferred Unit has a priority in liquidation equal to $25 per unit
plus an amount equal to the accumulated, accrued and unpaid dividends on a share
of Class D Preferred Stock.
    
 
CLASS E PARTNERSHIP PREFERRED UNITS
 
   
     In connection with the Insignia Merger, AIMCO will issue up to 8,945,921
shares of Class E Preferred Stock. AIMCO will contribute assets formerly held by
Insignia to the AIMCO Operating Partnership in exchange for Class E Partnership
Preferred Units issued to the Special Limited Partner. The terms of the Class E
Partnership Preferred Units are substantially the same as the terms of the Class
E Preferred Stock. The Class E Partnership Preferred Units entitle the Special
Limited Partner to receive preferred quarterly distributions equal (on a per
unit basis) to the dividends paid on the AIMCO Class A Common Stock (on a per
share basis), and a special distribution of $50 million in the aggregate. Upon
payment of the special distribution, the Class E Partnership Preferred Units
automatically convert into an equal number of Common OP Units. Each Class E
Partnership Preferred Unit has a priority in liquidation equal to $1.00 per unit
plus an amount equal to the accumulated, accrued and unpaid dividends on a share
of Class E Preferred Stock.
    
 
   
CLASS F PARTNERSHIP PREFERRED UNITS
    
 
   
     In connection with the Insignia Merger, AIMCO has assumed Insignia's
obligations under its 6 1/2% Convertible Subordinated Debentures due 2016 (the
"Convertible Debentures"), and the AIMCO Operating Partnership has issued Class
F Partnership Preferred Units to the Special Limited Partner that are
economically equivalent to the Convertible Debentures. The Convertible
Debentures bear interest at the rate of 6 1/2% per annum and are convertible
into shares of AIMCO Class E Preferred Stock at a price of $57.21. After the
conversion of Class E Preferred Stock into Class A Common Stock, the Convertible
Debentures will be convertible into shares of Class A Common Stock at a
conversion price that is adjusted for the $50 million dividend paid on the Class
E Preferred Stock. The Class F Partnership Preferred Units have a liquidation
value of $50 per Class F Partnership Preferred Unit, plus an amount per Class F
Partnership Unit equal to all accrued and unpaid interest on Convertible
Debentures in a principal amount of $50 to the date of final distribution to
holders of Class F Partnership Preferred Units (but such holders would not be
entitled to any further payment). Holders of Class F Partnership Preferred Units
are entitled to receive, on any date on which payments of interest or principal
are made on Convertible Debentures, distributions payable in cash in an amount
per Class F Partnership Preferred Unit equal to the interest and principal
payment made in respect of Convertible Debentures in a principal amount of $50
on such distribution date. Class F Partnership Preferred Units are redeemable by
the AIMCO Operating Partnership at any time that AIMCO redeems all or any of the
Convertible Debentures, in number equal to the quotient obtained by dividing the
aggregate principal amount of Convertible Debentures so redeemed by $50, at a
price per Class F Partnership Preferred Unit equal to the price paid by AIMCO to
redeem Convertible Debentures in a principal amount of $50. Upon any conversion
of Convertible Debentures into shares of AIMCO Class E Preferred Stock or Class
A Common
    
 
                                       49
<PAGE>   158
 
   
Stock, a number of Class F Partnership Preferred Units equal to the quotient
obtained by dividing the aggregate principal amount of Convertible Debentures so
converted by $50 will be converted into Class E Partnership Preferred Units or
Partnership Common Units, respectively. The conversion ratio in effect from time
to time for such conversion of Class F Partnership Preferred Units into Class E
Partnership Preferred Units or Partnership Common Units will be equal to, and
automatically adjusted to reflect, the conversion ratio in effect from time to
time for the conversion of Convertible Debentures in a principal amount equal to
$50 into shares of AIMCO's Class E Preferred Stock or Class A Common Stock, as
the case may be. The Class F Partnership Preferred Units may be owned and held
solely by AIMCO GP or the Special Limited Partner.
    
 
CLASS G PARTNERSHIP PREFERRED UNITS
 
   
     On July 15, 1998, in connection with AIMCO's issuance of 4,050,000 shares
of Class G Preferred Stock, the AIMCO Operating Partnership issued 4,050,000
Class G Partnership Preferred Units to the Special Limited Partner. The terms of
the Class G Partnership Preferred Units are substantially the same as the terms
of the Class G Preferred Stock. The Class G Partnership Preferred Units entitle
the Special Limited Partner to receive preferred quarterly cash distributions of
$0.5859375 ($2.34375 per annum). In addition, each Class G Partnership Preferred
Unit has a priority in liquidation equal to $25 per unit plus an amount equal to
the accumulated, accrued and unpaid dividends on a share of Class G Preferred
Stock.
    
 
CLASS H PARTNERSHIP PREFERRED UNITS
 
   
     On August 11, 1998, in connection with AIMCO's issuance of 2,000,000 shares
of Class H Preferred Stock, the AIMCO Operating Partnership issued 2,000,000
Class H Partnership Preferred Units to the Special Limited Partner. The terms of
the Class H Partnership Preferred Units are substantially the same as the terms
of the Class H Preferred Stock. The Class H Partnership Preferred Units entitle
the Special Limited Partner to receive preferred quarterly cash distributions of
$0.59375 ($2.375 per annum). In addition, each Class H Partnership Preferred
Unit has a priority in liquidation equal to $25 per unit plus an amount equal to
the accumulated, accrued and unpaid dividends on a share of Class H Preferred
Stock.
    
 
HIGH PERFORMANCE UNITS
 
     In January 1998, the AIMCO Operating Partnership sold an aggregate of
15,000 High Performance Units to a joint venture formed by fourteen of AIMCO's
officers and to three of AIMCO's independent directors, Messrs. Martin, Rhodes
and Smith. Holders of High Performance Units have no rights to receive
distributions or allocations of income or loss, or to redeem their High
Performance Units prior to the Valuation Date that is the earlier of (i) January
1, 2001, or (ii) the date on which a change of control (as defined in the AIMCO
Operating Partnership Agreement) occurs. If, on the Valuation Date, the
cumulative Total Return of the Class A Common Stock during the Measurement
Period exceeds the Minimum Return, then, on and after the Valuation Date,
holders of the 15,000 High Performance Units will be entitled to receive
distributions and allocations of income and loss from the AIMCO Operating
Partnership in the same amounts and at the same times (subject to certain
exceptions upon liquidation of the AIMCO Operating Partnership) as would holders
of a number of Common OP Units equal to the quotient obtained by dividing (i)
the product of (A) 15% of the amount by which the cumulative Total Return of the
Class A Common Stock over the Measurement Period exceeds the greater of 115% of
the peer group index or the Minimum Return, multiplied by (B) the weighted
average market value of AIMCO's equity capitalization (including Class A Common
Stock and Common OP Units) by (ii) the market value of one share of Class A
Common Stock on the Valuation Date. If, on the Valuation Date, the cumulative
Total Return of the Class A Common Stock does not satisfy these criteria, then,
on and after the Valuation Date, holders of the 15,000 High Performance Units
will be entitled to receive distributions and allocations of income and loss
from the AIMCO Operating Partnership in the same amounts and at the same times
(subject to certain exceptions upon a liquidation of the AIMCO Operating
Partnership) as would holders of 150 Common OP Units. For purposes of
determining the market value of Class A Common Stock or Common OP Units as of
any date, the average closing price of the Class A Common Stock for the 20
trading days immediately preceding such date
 
                                       50

is used. It is expected that the Morgan Stanley REIT Index, a
capitalization-weighted index with dividends reinvested of the most actively
traded REITs, will be used as the peer group index for purposes of the High
Performance Units.
 
     Upon the occurrence of a change of control, any holder of High Performance
Units may, subject to certain restrictions, require the AIMCO Operating
Partnership to redeem all or a portion of the High Performance Units held by
such party in exchange for a cash payment per unit equal to the market value of
a share of Class A Common Stock at the time of redemption. However, in the event
that any High Performance Units are tendered for redemption, the AIMCO Operating
Partnership's obligation to pay the redemption price is subject to the prior
right of AIMCO to acquire such High Performance Units in exchange for an equal
number of shares of Class A Common Stock (subject to certain adjustments).
 
DISTRIBUTIONS
 
   
     Preferred OP Units. Holders of Preferred OP Units to be issued hereunder
will have rights to distributions as set forth in the Prospectus Supplement.
With respect to rights of holders of Class B Partnership Preferred Units, Class
C Partnership Preferred Units, Class D Partnership Preferred Units, Class E
Partnership Preferred Units, Class F Partnership Preferred Units, Class G
Partnership Preferred Units and Class H Partnership Preferred Units, see
"-- Class B Partnership Preferred Units; -- Class C Partnership Preferred Units;
- -- Class D Partnership Preferred Units; -- Class E Partnership Preferred Units;
- -- Class F Partnership Preferred Units; -- Class G Partnership Preferred Units;
and -- Class H Partnership Preferred Units."
    
 
     High Performance Units. On and after the Valuation Date, holders of High
Performance Units may be entitled to receive distributions in accordance with
the terms of the High Performance Units. See "-- High Performance Units."
 
     Common OP Units. Subject to the rights of holders of any outstanding
Preferred OP Units, the AIMCO Operating Partnership Agreement requires the AIMCO
GP to cause the AIMCO Operating Partnership to distribute quarterly all, or such
portion as the AIMCO GP may in its sole and absolute discretion determine, of
Available Cash (as defined in the AIMCO Operating Partnership Agreement)
generated by the AIMCO Operating Partnership during such quarter to the AIMCO
GP, the Special Limited Partner and the holders of Common OP Units ("Common OP
Unitholders") on the record date established by the AIMCO GP with respect to
such quarter, in accordance with their respective interests in the AIMCO
Operating Partnership on such record date. Holders of any other Preferred OP
Units issued in the future may have priority over the AIMCO GP, the Special
Limited Partner and holders of Common OP Units with respect to distributions of
Available Cash, distributions upon liquidation or other distributions.
 
   
     Distributions payable with respect to any interest in the AIMCO Operating
Partnership that was not outstanding during the entire quarterly period in
respect of which any distribution is made will be prorated based on the portion
of the period that such interest was outstanding. The AIMCO GP in its sole and
absolute discretion may distribute to the OP Unitholders Available Cash on a
more frequent basis and provide for an appropriate record date. The AIMCO
Operating Partnership Agreement requires the AIMCO GP to take such reasonable
efforts, as determined by it in its sole and absolute discretion and consistent
with AIMCO's qualification as a REIT, to cause the AIMCO Operating Partnership
to distribute sufficient amounts to enable the AIMCO GP to transfer funds to
AIMCO and enable AIMCO to pay stockholder dividends that will (i) satisfy the
requirements (the "REIT Requirements") for qualifying as a REIT under the
Internal Revenue Code, and the Treasury Regulations and (ii) avoid any federal
income or excise tax liability of AIMCO.
    
 
   
     No Common OP Unitholder has any right to demand or receive property other
than cash as provided in the AIMCO Operating Partnership Agreement. The AIMCO GP
may determine, in its sole and absolute discretion, to make a distribution in
kind of assets of the AIMCO Operating Partnership to the OP Unitholders, and
such assets will be distributed in such a fashion as to ensure that the fair
market value is distributed and allocated in accordance with the AIMCO Operating
Partnership Agreement.
    
 
                                       51
<PAGE>   160
 
   
     Subject to the rights of holders of any outstanding Preferred OP Units, net
proceeds from the sale or other disposition of all or substantially all of the
assets of the AIMCO Operating Partnership or a related series of transactions
that, taken together, result in the sale or other disposition of all or
substantially all of the assets of the AIMCO Operating Partnership (a
"Terminating Capital Transaction"), and any other cash received or reductions in
reserves made after commencement of the liquidation of the AIMCO Operating
Partnership, will be distributed to the OP Unitholders in accordance with the
AIMCO Operating Partnership Agreement.
    
 
   
     The AIMCO Operating Partnership Agreement prohibits the AIMCO Operating
Partnership and the AIMCO GP, on behalf of the AIMCO Operating Partnership, from
making a distribution to any OP Unitholder on account of its interest in OP
Units if such distribution would violate Section 17-607 of the Delaware LP Act
or other applicable law.
    
 
ALLOCATIONS OF NET INCOME AND NET LOSS
 
   
     Preferred OP Units. With respect to the Class B Partnership Preferred
Units, the Class C Partnership Preferred Units, the Class D Partnership
Preferred Units, the Class E Partnership Preferred Units, the Class F
Partnership Preferred Units, the Class G Partnership Preferred Units, the Class
H Partnership Preferred Units and any similar class of Preferred OP Unit that
may be subsequently issued, gross income and, if necessary, gain will be
allocated to the holders of the Preferred OP Units for any fiscal year (and, if
necessary, subsequent fiscal years) to the extent that the holders of the
Preferred OP Units receive a distribution on any Preferred OP Units (other than
an amount included in any redemption of Preferred OP Units). If any Preferred OP
Units are redeemed, for the fiscal year that includes such redemption (and, if
necessary, for subsequent fiscal years) (i) gross income and gain (in such
relative proportions as the AIMCO GP in its discretion will determine) will be
allocated to the holders of such class of Preferred OP Units to the extent that
the redemption amounts paid or payable with respect to the Preferred OP Units so
redeemed exceeds the aggregate capital contributions (net of liabilities assumed
or taken subject to by the AIMCO Operating Partnership) per Preferred OP Unit
allocable to the Preferred OP Units so redeemed and (ii) deductions and losses
(in such relative proportions as the AIMCO GP in its discretion will determine)
will be allocated to the holders of such class of Preferred OP Units to the
extent that the aggregate Capital Contributions (net of liabilities assumed or
taken subject to by the AIMCO Operating Partnership) per Preferred OP Unit
allocable to the Preferred OP Units so redeemed exceeds the redemption amount
paid or payable with respect to the Preferred OP Units so redeemed.
    
 
     High Performance Units. On and after the Valuation Date, holders of High
Performance Units may be allocated income and loss in accordance with the terms
of the High Performance Units. See "-- High Performance Units."
 
   
     Common OP Units. Net Income (as defined in the AIMCO Operating Partnership
Agreement) and Net Loss (as defined in the AIMCO Operating Partnership
Agreement) of the AIMCO Operating Partnership will be determined and allocated
with respect to each fiscal year of the AIMCO Operating Partnership as of the
end of each such year. Except as otherwise provided in the AIMCO Operating
Partnership Agreement, an allocation to a Common OP Unitholder of a share of Net
Income or Net Loss will be treated as an allocation of the same share of each
item of income, gain, loss or deduction that is taken into account in computing
Net Income or Net Loss. Except as otherwise provided in the AIMCO Operating
Partnership Agreement and subject to the terms of any outstanding Partnership
Preferred Units, Net Income and Net Loss will be allocated to the holders of
Common OP Units in accordance with their respective Common OP Units at the end
of each fiscal year. The AIMCO Operating Partnership Agreement contains
provisions for special allocations intended to comply with certain regulatory
requirements, including the requirements of Treasury Regulations Sections
1.704-1(b) and 1.704-2. Except as otherwise provided in the AIMCO Operating
Partnership Agreement and subject to the terms of any outstanding Preferred OP
Units, for income tax purposes under the Internal Revenue Code and the Treasury
Regulations, each Partnership item of income, gain, loss and deduction will be
allocated among the Common OP Unitholders in the same manner as its correlative
item of "book" income, gain, loss or deduction is allocated pursuant to the
AIMCO Operating Partnership Agreement.

<PAGE>   161
 
WITHHOLDING
 
   
     The AIMCO Operating Partnership is authorized to withhold from or pay on
behalf of or with respect to each limited partner any amount of federal, state,
local or foreign taxes that the AIMCO GP determines that the AIMCO Operating
Partnership is required to withhold or pay with respect to any amount
distributable or allocable to such limited partner pursuant to the AIMCO
Operating Partnership Agreement.
    
 
RETURN OF CAPITAL
 
   
     No limited partner is entitled to interest on its capital contribution or
on such limited partner's capital account. Except (i) pursuant to the rights of
redemption set forth in the AIMCO Operating Partnership Agreement, (ii) as
provided by law, or (iii) pursuant to the terms of any outstanding Preferred OP
Units, no limited partner has any right to demand or receive the withdrawal or
return of its capital contribution from the AIMCO Operating Partnership, except
to the extent of distributions made pursuant to the AIMCO Operating Partnership
Agreement or upon termination of the AIMCO Operating Partnership. Except to the
extent otherwise expressly provided in the AIMCO Operating Partnership Agreement
and subject to the terms of any outstanding Preferred OP Units, no limited
partner or assignee will have priority over any other limited partner or
assignee either as to the return of capital contributions or as to profits,
losses or distributions.
    
 
REDEMPTION RIGHTS
 
   
     Preferred OP Units. Holders of Preferred OP Units to be issued hereunder
will have rights to redemption as set forth in the applicable Prospectus
Supplement. With respect to rights of holders of Class B Partnership Preferred
Units, Class C Partnership Preferred Units, Class D Partnership Preferred Units,
Class E Partnership Preferred Units, Class F Partnership Preferred Units, Class
G Partnership Preferred Units and Class H Partnership Preferred Units, see
"-- Class B Partnership Preferred Units; -- Class C Partnership Preferred Units;
- -- Class D Partnership Preferred Units; -- Class E Partnership Preferred Units;
- -- Class F Partnership Preferred Units; and -- Class H Partnership Preferred
Units."
    
 
     High Performance Units. In the event of a change of control, holders of
High Performance Units will have the same redemption rights as holders of Common
OP Units. See "-- High Performance Units."
 
   
     Common OP Units. After the first anniversary of becoming a holder of Common
OP Units, each Common OP Unitholder and certain assignees have the right,
subject to the terms and conditions set forth in the AIMCO Operating Partnership
Agreement, to require the AIMCO Operating Partnership to redeem all or a portion
of the Common OP Units held by such party in exchange for a cash amount based on
the value of shares of Class A Common Stock. The AIMCO Operating Partnership's
obligation to effect a redemption, however, will not arise or be binding against
the AIMCO Operating Partnership until and unless AIMCO declines or fails to
exercise its right to acquire such Common OP Units pursuant to the AIMCO
Operating Partnership Agreement.
    
 
   
     On or before the close of business on the fifth business day after a Common
OP Unitholder gives the AIMCO GP a notice of redemption, the AIMCO GP may, in
its sole and absolute discretion but subject to the restrictions on the
ownership of Class A Common Stock imposed under the AIMCO Charter and the
transfer restrictions and other limitations thereof, elect to cause AIMCO to
acquire some or all of the tendered Common OP Units from the tendering party in
exchange for Class A Common Stock, based on an exchange ratio of one share of
Class A Common Stock for each Common OP Unit, subject to adjustment as provided
in the AIMCO Operating Partnership Agreement.
    
 
PARTNERSHIP RIGHT TO CALL COMMON OP UNITS
 
   
     Notwithstanding any other provision of the AIMCO Operating Partnership
Agreement, on and after the date on which the aggregate percentage interests of
the limited partners, other than the Special Limited Partner, are less than one
percent (1%), the AIMCO Operating Partnership will have the right, but not the
obligation, from time to time and at any time to redeem any and all outstanding
limited partner interests (other than the Special Limited Partner's interest) in
the AIMCO Operating Partnership by treating any
    
 
                                       53
<PAGE>   162
 
   
limited partner as if such limited partner had tendered for redemption pursuant
to the AIMCO Operating Partnership Agreement the amount of Common OP Units
specified by the AIMCO GP, in its sole and absolute discretion, by notice to the
limited partner.
    
 
TRANSFERS AND WITHDRAWALS
 
   
     Restrictions on Transfer. The AIMCO Operating Partnership Agreement
restricts the transferability of OP Units. Any transfer or purported transfer of
an OP Unit not made in accordance with the AIMCO Operating Partnership Agreement
will be null and void ab initio. Until the expiration of one year from the date
on which a limited partner acquired OP Units, subject to certain exceptions,
such limited partner may not transfer all or any portion of its OP Units to any
transferee without the consent of the AIMCO GP, which consent may be withheld in
its sole and absolute discretion. After the expiration of one year from the date
on which a limited partner acquired OP Units, such limited partner has the right
to transfer all or any portion of its OP Units to any person, subject to the
satisfaction of certain conditions specified in the AIMCO Operating Partnership
Agreement, including the AIMCO GP's right of first refusal. It is a condition to
any transfer (regardless of whether such transfer is effected before or after
the one year holding period) that the transferee assumes by operation of law or
express agreement all of the obligations of the transferor limited partner under
the AIMCO Operating Partnership Agreement with respect to such OP Units, and no
such transfer (other than pursuant to a statutory merger or consolidation
wherein all obligations and liabilities of the transferor partner are assumed by
a successor corporation by operation of law) will relieve the transferor partner
of its obligations under the AIMCO Operating Partnership Agreement without the
approval of the AIMCO GP, in its sole and absolute discretion.
    
 
   
     In connection with any transfer of OP Units, the AIMCO GP will have the
right to receive an opinion of counsel reasonably satisfactory to it to the
effect that the proposed transfer may be effected without registration under the
Securities Act of 1933 and will not otherwise violate any federal or state
securities laws or regulations applicable to the AIMCO Operating Partnership or
the OP Units transferred.
    
 
   
     No transfer by a limited partner of its OP Units (including any redemption
or any acquisition of OP Units by the AIMCO GP or by the AIMCO Operating
Partnership) may be made to any person if (i) in the opinion of legal counsel
for the AIMCO Operating Partnership, it would result in the AIMCO Operating
Partnership being treated as an association taxable as a corporation, or (ii)
such transfer is effectuated through an "established securities market" or a
"secondary market (or the substantial equivalent thereof)" within the meaning of
Section 7704 of the Internal Revenue Code.
    
 
   
     Substituted Limited Partners. No limited partner will have the right to
substitute a transferee as a limited partner in its place. A transferee of the
interest of a limited partner may be admitted as a substituted limited partner
only with the consent of the AIMCO GP, which consent may be given or withheld by
the AIMCO GP in its sole and absolute discretion. If the AIMCO GP, in its sole
and absolute discretion, does not consent to the admission of any permitted
transferee as a substituted limited partner, such transferee will be considered
an assignee for purposes of the AIMCO Operating Partnership Agreement. An
assignee will be entitled to all the rights of an assignee of a limited
partnership interest under the Delaware LP Act, including the right to receive
distributions from the AIMCO Operating Partnership and the share of Net Income,
Net Losses and other items of income, gain, loss, deduction and credit of the
AIMCO Operating Partnership attributable to the OP Units assigned to such
transferee and the rights to transfer the OP Units provided in the AIMCO
Operating Partnership Agreement, but will not be deemed to be a limited partner
for any other purpose under the AIMCO Operating Partnership Agreement, and will
not be entitled to effect a consent or vote with respect to such OP Units on any
matter presented to the limited partners for approval (such right to consent or
vote, to the extent provided in this Agreement or under the Delaware LP Act,
fully remaining with the transferor limited partner).
    
 
   
     Withdrawals. No limited partner may withdraw from the AIMCO Operating
Partnership other than as a result of a permitted transfer of all of such
limited partner's OP Units in accordance with the AIMCO Operating Partnership
Agreement, with respect to which the transferee becomes a substituted limited
partner, or pursuant to a redemption (or acquisition by AIMCO) of all of such
limited partner's OP Units.
    
 
                                       54
<PAGE>   163
 
   
     Restrictions on the General Partner. The AIMCO GP may not transfer any of
its general partner interest or withdraw from the AIMCO Operating Partnership
unless (i) the limited partners consent or (ii) immediately after a merger of
the AIMCO GP into another entity, substantially all of the assets of the
surviving entity, other than the general partnership interest in the AIMCO
Operating Partnership held by the AIMCO GP, are contributed to the AIMCO
Operating Partnership as a capital contribution in exchange for OP Units.
    
 
ISSUANCE OF CAPITAL STOCK BY AIMCO
 
   
     Pursuant to the AIMCO Operating Partnership Agreement, upon the issuance of
its capital stock, AIMCO is generally obligated to contribute the cash proceeds
or other consideration received from such issuance to the AIMCO Operating
Partnership in exchange for, in the case of Class A Common Stock, Common OP
Units, or in the case of an issuance of Preferred Stock, Preferred OP Units with
designations, preferences and other rights, terms and provisions that are
substantially the same as the designations, preferences and other rights, terms
and provisions of such Preferred Stock.
    
 
DILUTION
 
   
     The AIMCO GP has the power, without the consent of the limited partners, to
cause the AIMCO Operating Partnership to issue additional Common OP Units and
Preferred OP Units. Any such issuance may dilute the interests of existing OP
Unitholders. In addition, the terms of the Preferred OP Units entitle the
holders thereof to receive preferential distributions of cash and a priority in
liquidation, as well as certain class voting rights.
    
 
AMENDMENT OF THE AIMCO OPERATING PARTNERSHIP AGREEMENT
 
   
     By the AIMCO GP Without the Consent of the Limited Partners. The AIMCO GP
has the power, without the consent of the limited partners, to amend the AIMCO
Operating Partnership Agreement as may be required to facilitate or implement
any of the following purposes: (1) to add to the obligations of the AIMCO GP or
surrender any right or power granted to the AIMCO GP or any affiliate of the
AIMCO GP for the benefit of the limited partners; (2) to reflect the admission,
substitution or withdrawal of partners or the termination of the AIMCO Operating
Partnership in accordance with the AIMCO Operating Partnership Agreement; (3) to
reflect a change that is of an inconsequential nature and does not adversely
affect the limited partners in any material respect, or to cure any ambiguity,
correct or supplement any provision in the AIMCO Operating Partnership Agreement
not inconsistent with law or with other provisions, or make other changes with
respect to matters arising under the AIMCO Operating Partnership Agreement that
will not be inconsistent with law or with the provisions of the AIMCO Operating
Partnership Agreement; (4) to satisfy any requirements, conditions or guidelines
contained in any order, directive, opinion, ruling or regulation of a federal or
state agency or contained in federal or state law; (5) to reflect such changes
as are reasonably necessary for AIMCO to maintain its status as a REIT; and (6)
to modify the manner in which capital accounts are computed (but only to the
extent set forth in the definition of "Capital Account" in the AIMCO Operating
Partnership Agreement or contemplated by the Internal Revenue Code or the
Treasury Regulations).
    
 
   
     With the Consent of the Limited Partners. With the exception of the
circumstances described above whereby the AIMCO GP may, without the consent of
the limited partners, amendments to the AIMCO Operating Partnership Agreement
require the limited partners' consent. Amendments to the AIMCO Operating
Partnership Agreement may be proposed by the AIMCO GP or by limited partners
holding a majority of the outstanding Common OP Units, excluding the Special
Limited Partner (a "Majority in Interest"). Following such proposal, the AIMCO
GP will submit any proposed amendment to the limited partners. The AIMCO GP will
seek the written consent of the limited partners on the proposed amendment or
will call a meeting to vote thereon and to transact any other business that the
AIMCO GP may deem appropriate. For purposes of obtaining a written consent, the
AIMCO GP may require a written response within a reasonable specified time, but
not less than fifteen (15) days, and failure to respond in such time period
shall constitute a consent that is consistent with the AIMCO GP's recommendation
with respect to the
    
 
                                       55
<PAGE>   164
 
proposal, provided, however, that an action shall become effective at such time
as requisite consents are received even if prior to such specified time.
 
PROCEDURES FOR ACTIONS AND CONSENTS OF PARTNERS
 
   
     Meetings of the partners may be called by the AIMCO GP and will be called
upon the receipt by the AIMCO GP of a written request by a Majority in Interest
of the limited partners. Notice of any such meeting will be given to all
partners not less than seven (7) days nor more than thirty (30) days prior to
the date of such meeting. Partners may vote in person or by proxy at such
meeting. Each meeting of partners will be conducted by the AIMCO GP or such
other person as the AIMCO GP may appoint pursuant to such rules for the conduct
of the meeting as the AIMCO GP or such other person deems appropriate in its
sole and absolute discretion. Any action required or permitted to be taken at a
meeting of the partners may be taken without a meeting if a written consent
setting forth the action so taken is signed by partners holding a majority of
outstanding Common OP Units (or such other percentage as is expressly required
by the AIMCO Operating Partnership Agreement for the action in question). Such
consent may be in one instrument or in several instruments, and shall have the
same force and effect as a vote of the partners holding a majority of
outstanding Common OP Units (or such other percentage as is expressly required
by the AIMCO Operating Partnership Agreement for the action in question). Such
consent shall be filed with the AIMCO GP. An action so taken shall be deemed to
have been taken at a meeting held on the effective date so certified.
    
 
RECORDS AND ACCOUNTING; FISCAL YEAR
 
     The AIMCO Operating Partnership Agreement requires the AIMCO GP to keep or
cause to be kept at the principal office of the AIMCO Operating Partnership
those records and documents required to be maintained by the Delaware LP Act and
other books and records deemed by the AIMCO GP to be appropriate with respect to
the AIMCO Operating Partnership's business. The books of the AIMCO Operating
Partnership will be maintained, for financial and tax reporting purposes, on an
accrual basis in accordance with generally accepted accounting principles, or on
such other basis as the AIMCO GP determines to be necessary or appropriate. To
the extent permitted by sound accounting practices and principles, the AIMCO
Operating Partnership, the AIMCO GP and AIMCO may operate with integrated or
consolidated accounting records, operations and principles. The fiscal year of
the AIMCO Operating Partnership is the calendar year.
 
REPORTS
 
   
     As soon as practicable, but in no event later than one hundred five (105)
days after the close of each calendar quarter and each fiscal year, the AIMCO GP
will cause to be mailed to each limited partner, of record as of the last day of
the calendar quarter or as of the close of the fiscal year, as the case may be,
a report containing financial statements of the AIMCO Operating Partnership, or
of AIMCO if such statements are prepared solely on a consolidated basis with
AIMCO, for such calendar quarter or fiscal year, as the case may be, presented
in accordance with generally accepted accounting principles, and such other
information as may be required by applicable law or regulation or as the AIMCO
GP determines to be appropriate. Statements included in quarterly reports are
not audited. Statements included in annual reports are audited by a nationally
recognized firm of independent public accountants selected by the AIMCO GP.
    
 
TAX MATTERS
 
   
     The AIMCO GP is the "tax matters partner" of the AIMCO Operating
Partnership for federal income tax purposes. The tax matters partner is
authorized, but not required, to take certain actions on behalf of the AIMCO
Operating Partnership with respect to tax matters. In addition, the AIMCO GP
will arrange for the preparation and timely filing of all returns with respect
to the AIMCO Operating Partnership's income, gains, deductions, losses and other
items required of the AIMCO Operating Partnership for federal and state income
tax purposes and will use all reasonable effort to furnish, within ninety (90)
days of the close of each taxable year, the tax information reasonably required
by limited partners for federal and state income tax reporting
    
 
                                       56
<PAGE>   165
 
   
purposes. The limited partners will promptly provide the AIMCO GP with such
information as may be reasonably requested by the AIMCO GP from time to time.
    
 
DISSOLUTION AND WINDING UP
 
   
     Dissolution. The AIMCO Operating Partnership will dissolve, and its affairs
will be wound up, upon the first to occur of any of the following (each a
"Liquidating Event") (i) December 31, 2093; (ii) an event of withdrawal, as
defined in the Delaware LP Act (including, without limitation, bankruptcy), of
the sole general partner unless, within ninety (90) days after the withdrawal, a
"majority in interest" (as such phrase is used in Section 17-801(3) of the
Delaware LP Act) of the remaining partners agree in writing, in their sole and
absolute discretion, to continue the business of the AIMCO Operating Partnership
and to the appointment, effective as of the date of withdrawal, of a successor
general partner; (iii) an election to dissolve the AIMCO Operating Partnership
made by the general partner in its sole and absolute discretion, with or without
the consent of the limited partners; (iv) entry of a decree of judicial
dissolution of the AIMCO Operating Partnership pursuant to the provisions of the
Delaware LP Act; (v) the occurrence of a Terminating Capital Transaction; or
(vi) the redemption (or acquisition by AIMCO, the AIMCO GP and/or the Special
Limited Partner) of all Common OP Units other than Common OP Units held by the
AIMCO GP or the Special Limited Partner.
    
 
   
     Winding Up. Upon the occurrence of a Liquidating Event, the AIMCO Operating
Partnership will continue solely for the purposes of winding up its affairs in
an orderly manner, liquidating its assets and satisfying the claims of its
creditors and partners. The AIMCO GP (or, in the event that there is no
remaining AIMCO GP or the AIMCO GP has dissolved, become bankrupt within the
meaning of the Delaware LP Act or ceased to operate, any person elected by a
Majority in Interest of the limited partners) will be responsible for overseeing
the winding up and dissolution of the AIMCO Operating Partnership and will take
full account of the AIMCO Operating Partnership's liabilities and property, and
the AIMCO Operating Partnership's property will be liquidated as promptly as is
consistent with obtaining the fair value thereof, and the proceeds therefrom
(which may, to the extent determined by the AIMCO GP, include Class A Common
Stock) will be applied and distributed in the following order: (i) first, to the
satisfaction of all of the AIMCO Operating Partnership's debts and liabilities
to creditors other than the partners and their assignees (whether by payment or
the making of reasonable provision for payment thereof); (ii) second, to the
satisfaction of all the AIMCO Operating Partnership's debts and liabilities to
the general partner (whether by payment or the making of reasonable provision
for payment thereof), including, but not limited to, amounts due as
reimbursements under the AIMCO Operating Partnership Agreement; (ii) third, to
the satisfaction of all of the AIMCO Operating Partnership's debts and
liabilities to the other partners and any assignees (whether by payment or the
making of reasonable provision for payment thereof); (iv) fourth, to the
satisfaction of all liquidation preferences of outstanding Preferred OP Units,
if any, and (v) the balance, if any, to the AIMCO GP, the limited partners and
any assignees in accordance with and in proportion to their positive capital
account balances, after giving effect to all contributions, distributions and

            COMPARISON OF THE AIMCO OPERATING PARTNERSHIP AND AIMCO
 
   
     Generally, the nature of an investment in the Common OP Units is
substantially equivalent economically to an investment in the Class A Common
Stock. The AIMCO Operating Partnership makes quarterly distributions to holders
of Common OP Units (on a per unit basis) that generally are equal to the
dividends paid on the Class A Common Stock (on a per share basis). However, such
distributions will not necessarily continue to be equal to such dividends.
Common OP Unitholders generally share in the risks and rewards of ownership in
the enterprise being conducted by AIMCO (through the AIMCO Operating
Partnership). However, there are some differences between ownership of Common OP
Units and ownership of Class A Common Stock, some of which may be material to
investors.
    
 
     The information below highlights a number of the significant differences
between the AIMCO Operating Partnership and AIMCO relating to, among other
things, form of organization, permitted investments, policies and restrictions,
management structure, compensation and fees, investor rights and federal income
taxation, and compares certain legal rights associated with the ownership of
Common OP Units and Class A Common Stock, respectively. These comparisons are
intended to assist OP Unitholders in understanding how their investment will be
changed if their Common OP Units are exchanged for Class A Common Stock. COMMON
OP UNITHOLDERS SHOULD CAREFULLY REVIEW THE BALANCE OF THIS PROSPECTUS AND THE
REGISTRATION STATEMENT AND THE EXHIBITS THERETO OF WHICH THIS PROSPECTUS IS A
PART AND ANY APPLICABLE PROSPECTUS SUPPLEMENT FOR ADDITIONAL IMPORTANT
INFORMATION ABOUT THE COMPANY.

Stock"). This discussion is based upon the Code, the Treasury Regulations,
rulings issued by the IRS, and judicial decisions, all in effect as of the date
of this Registration Statement and all of which are subject to change, possibly
retroactively. Such summary is also based on the assumptions that the operation
of AIMCO, the AIMCO Operating Partnership and the limited liability companies
and limited partnerships in which they own controlling interests (collectively,
the "Subsidiary Partnerships") will be in accordance with their respective
organizational documents and partnership agreements. This summary is for general
information only and does not purport to discuss all aspects of federal income
taxation which may be important to a particular investor in light of its
investment or tax circumstances, or to certain types of investors subject to
special tax rules (including financial institutions, broker-dealers, insurance
companies, and, except to the extent discussed below, tax-exempt organizations
and foreign investors, as determined for United States federal income tax
purposes). This summary assumes that investors will hold their AIMCO Stock as
"capital assets" (generally, property held for investment). No advance ruling
has been or will be sought from the IRS regarding any matter discussed in this
Registration Statement.
    
 
     THE FEDERAL INCOME TAX TREATMENT OF HOLDERS OF AIMCO STOCK DEPENDS IN SOME
INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF COMPLEX PROVISIONS OF
FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE
AVAILABLE. ACCORDINGLY, EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF ACQUIRING,
HOLDING, EXCHANGING, OR OTHERWISE DISPOSING OF AIMCO STOCK AND OF AIMCO'S
ELECTION TO BE SUBJECT TO TAX, FOR FEDERAL INCOME TAX PURPOSES, AS A REAL ESTATE
INVESTMENT TRUST.
 
GENERAL
 
     The REIT provisions of the Code are highly technical and complex. The
following summary sets forth certain aspects of the provisions of the Code that
govern the federal income tax treatment of a REIT and its stockholders. This
summary is qualified in its entirety by the applicable Code provisions, Treasury
Regulations, and administrative and judicial interpretations thereof, all of
which are subject to change, possibly retroactively.
 
     AIMCO has elected to be taxed as a REIT under the Code commencing with its
taxable year ending December 31, 1994, and AIMCO intends to continue such
election. Although AIMCO believes, and it has received an opinion of Counsel to
the effect that, commencing with the AIMCO's initial taxable year ended December
31, 1994, AIMCO was organized in conformity with the requirements for
qualification as a REIT, and its proposed method of operation, and its actual
method of operation since its formation, will enable it to meet the requirements
for qualification and taxation as a REIT under the Code. No assurance can be
given that AIMCO has been or will remain so qualified. It must be emphasized
that this opinion is based and conditioned upon certain assumptions and
representations and covenants made by AIMCO as to factual matters (including
representations of AIMCO concerning its business and properties as set forth in
this Registration Statement). The opinion is expressed as of its date and
Counsel has no obligation to advise holders of Securities of any subsequent
change in the matters stated, represented or assumed or any subsequent change in
the applicable law. Moreover, such qualification and taxation as a REIT depends
upon AIMCO's ability to meet, through actual annual operating results,
distribution levels and diversity of stock ownership, the various qualification
tests imposed under the Code as discussed below, the results of which will not
be reviewed by Counsel. Accordingly, no assurance can be given that the actual
results of AIMCO's operation for any one taxable year will satisfy such
requirements. See " -- Failure to Qualify." An opinion of counsel is not binding
on the IRS, and no assurance can be given that the IRS will not challenge
AIMCO's eligibility for taxation as a REIT.
 
                                       67

     Provided AIMCO qualifies for taxation as a REIT, it will generally not be
subject to federal corporate income tax on its net income that is currently
distributed to its stockholders. This treatment substantially eliminates the
"double taxation" (at the corporate and stockholder levels) that generally
results from investment in a corporation. However, notwithstanding AIMCO's
qualification as a REIT, AIMCO will be subject to federal income tax as follows:
First, AIMCO will be taxed at regular corporate rates on any undistributed REIT
taxable income, including undistributed net capital gains. Second, under certain
circumstances, AIMCO may be subject to the "alternative minimum tax" on its
items of tax preference. Third, if AIMCO has net income from prohibited
transactions (which are, in general, certain sales or other dispositions of
property held primarily for sale to customers in the ordinary course of business
other than foreclosure property), such income will be subject to a 100% tax.
Fourth, if AIMCO should fail to satisfy the 75% gross income test or the 95%
gross income test (as discussed below), but has nonetheless maintained its
qualification as a REIT because certain other requirements have been met, it
will be subject to a 100% tax on an amount equal to (a) the gross income
attributable to the greater of the amount by which AIMCO fails the 75% or 95%
test multiplied by (b) a fraction intended to reflect AIMCO's profitability.
Fifth, if AIMCO should fail to distribute during each calendar year at least the
sum of (i) 85% of its REIT ordinary income for such year, (ii) 95% of its REIT
capital gain net income for such year (other than certain long-term capital
gains that AIMCO elects to retain and pay the tax thereon), and (iii) any
undistributed taxable income from prior periods, AIMCO would be subjected to a
4% excise tax on the excess of such required distribution over the amounts
actually distributed. Sixth, if AIMCO acquires assets from a subchapter C
corporation in a transaction in which the adjusted tax basis of the assets in
the hands of AIMCO is determined by reference to the adjusted tax basis of such
assets in the hands of the subchapter C corporation (such as the assets acquired
from Insignia in the Insignia Merger), under Treasury Regulations not yet
promulgated, the subchapter C corporation would be required to recognize any net
Built-In Gain (as defined below) that would have been realized if the Subchapter
C corporation had liquidated on the day before the date of the transfer.
Pursuant to IRS Notice 88-19, AIMCO may elect, in lieu of the treatment
described above, to be subject to tax at the highest regular corporate tax rate
on such gain to the extent of the excess, if any, of the fair market value over
the adjusted basis of such asset as of the beginning of the ten-year period
("Built-in Gain"). AIMCO intends to make such an election and, therefore, will
be taxed at the highest regular corporate rate on such Built-in Gain if, and to
the extent, such assets are sold within the specified ten-year period. It should
be noted that AIMCO has acquired (and will acquire in the Insignia Merger) a
significant amount of assets with Built-in Gain and a taxable disposition by
AIMCO of any of these assets within ten years of their acquisitions would
subject AIMCO to tax under the foregoing rule. Seventh, AIMCO could be subject
to foreign taxes on its investments and activities in foreign jurisdictions. In
addition, AIMCO could also be subject to tax in certain situations and on
certain transactions not presently contemplated.
 
  Requirements for Qualification
 
     The Code defines a REIT as a corporation, trust or association (1) that is
managed by one or more trustees or directors; (2) the beneficial ownership of
which is evidenced by transferable shares, or by transferable certificates of
beneficial interest; (3) which would be taxable as a domestic corporation, but
for the special Code provisions applicable to REITs; (4) that is neither a
financial institution nor an insurance company subject to certain provisions of
the Code; (5) the beneficial ownership of which is held by 100 or more persons;
(6) in which, during the last half of each taxable year, not more than 50% in
value of the outstanding stock is owned, directly or indirectly, by five or
fewer individuals (as defined in the Code to include certain entities); and (7)
which meets certain other tests described below (including with respect to the
nature of its income and assets). The Code provides that conditions (1) through
(4) must be met during the entire taxable year, and that condition (5) must be
met during at least 335 days of a taxable year of 12 months, or during a
proportionate part of a taxable year of less than 12 months. The Charter
provides certain restrictions regarding transfers of its shares, which
provisions are intended to assist AIMCO in satisfying the share ownership
requirements described in conditions (5) and (6) above.
 
     To monitor AIMCO's compliance with the share ownership requirements, AIMCO
is required to maintain records regarding the actual ownership of its shares. To
do so, AIMCO must demand written statements each year from the record holders of
certain percentages of its stock in which the record holders are
 
                                       68
<PAGE>   177
 
to disclose the actual owners of the shares (i.e., the persons required to
include in gross income the REIT dividends). A list of those persons failing or
refusing to comply with this demand must be maintained as part of AIMCO's
records. A stockholder who fails or refuses to comply with the demand must
submit a statement with its tax return disclosing the actual ownership of the
shares and certain other information.
 
     In addition, a corporation may not elect to become a REIT unless its
taxable year is the calendar year. AIMCO satisfies this requirement.
 
  Ownership of Partnership Interests
 
     In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that the REIT is deemed to own its proportionate share of
the partnership's assets and to earn its proportionate share of the
partnership's income. In addition, the assets and gross income of the
partnership retain the same character in the hands of the REIT for purposes of
the gross income and asset tests applicable to REITs as described below. Thus,
AIMCO's proportionate share of the assets, liabilities and items of income of
the partnerships and limited liability companies in which it has ownership
interests (the "Subsidiary Partnerships") will be treated as assets, liabilities
and items of income of AIMCO for purposes of applying the REIT requirements
described herein. A summary of certain rules governing the federal income
taxation of partnerships and their partners is provided below in "Tax Aspects of
AIMCO's Investments in Partnerships."
 
  Income Tests
 
     In order to maintain qualification as a REIT, AIMCO annually must satisfy
two gross income requirements. First, at least 75% of AIMCO's gross income
(excluding gross income from "prohibited transactions," i.e., certain sales of
property held primarily for sale to customers in the ordinary course of
business) for each taxable year must be derived directly or indirectly from
investments relating to real property or mortgages on real property (including
"rents from real property" and, in certain circumstances, interest) or from
certain types of temporary investments. Second, at least 95% of AIMCO's gross
income (excluding gross income from prohibited transactions) for each taxable
year must be derived from such real property investments, and from dividends,
interest and gain from the sale or disposition of stock or securities (or from
any combination of the foregoing).
 
     Rents received by AIMCO through the Subsidiary Partnerships will qualify as
"rents from real property" in satisfying the gross income requirements described
above, only if several conditions are met, including the following. If rent
attributable to personal property leased in connection with a lease of real
property is greater than 15% of the total rent received under the lease, then
the portion of rent attributable to such personal property will not qualify as
"rents from real property." Moreover, for rents received to qualify as "rents
from real property," the REIT generally must not operate or manage the property
or furnish or render services to the tenants of such property, other than
through an "independent contractor" from which the REIT derives no revenue.
However, AIMCO (or its affiliates) is permitted to directly perform services
that are "usually or customarily rendered" in connection with the rental of
space for occupancy only and are not otherwise considered rendered to the
occupant of the property. In addition, AIMCO (or its affiliates) may provide
non-customary services to tenants of its properties without disqualifying all of
the rent from the property if the payment for such services does not exceed 1%
of the total gross income from the property. For purposes of this test, the
income received from such non-customary services is deemed to be at least 150%
of the direct cost of providing the services.
 
     PAMS LP and the other subsidiaries of the Company that manage the Managed
Properties (collectively, the "Management Subsidiaries") receive management fees
and other income. A portion of such fees and other income accrue to AIMCO
through distributions from the Management Subsidiaries that will be classified
as dividend income to the extent of the earnings and profits of the Management
Subsidiaries. Such distributions will generally qualify under the 95% gross
income test but not under the 75% gross income test.
 
     If AIMCO fails to satisfy one or both of the 75% or 95% gross income tests
for any taxable year, it may nevertheless qualify as a REIT for such year if it
is entitled to relief under certain provisions of the Code. These relief
provisions will be generally available if AIMCO's failure to meet such tests was
due to reasonable
 
                                       69
<PAGE>   178
 
cause and not due to willful neglect, AIMCO attaches a schedule of the sources
of its income to its return, and any incorrect information on the schedule was
not due to fraud with intent to evade tax. It is not possible, however, to state
whether in all circumstances AIMCO would be entitled to the benefit of these
relief provisions. If these relief provisions are inapplicable to a particular
set of circumstances involving AIMCO, AIMCO will not qualify as a REIT. As
discussed above in "-- General," even where these relief provisions apply, a tax
is imposed with respect to the excess net income.
 
  Asset Tests
 
     AIMCO, at the close of each quarter of its taxable year, must also satisfy
three tests relating to the nature of its assets. First, at least 75% of the
value of AIMCO's total assets must be represented by real estate assets
(including its allocable share of real estate assets held by the Subsidiary
Partnerships), certain stock or debt instruments purchased by AIMCO with new
capital, cash, cash items and U.S. government securities. Second, not more than
25% of AIMCO's total assets may be represented by securities other than those in
the 75% asset class. Third, of the investments included in the 25% asset class,
the value of any one issuer's securities owned by AIMCO may not exceed 5% of the
value of AIMCO's total assets, and AIMCO may not own more than 10% of any one
issuer's outstanding voting securities.
 
     AIMCO indirectly owns interests in the Management Subsidiaries. As set
forth above, the ownership of more than 10% of the voting securities of any one
issuer by a REIT or the investment of more than 5% of the REIT's total assets in
any one issuer's securities is prohibited by the asset tests. AIMCO believes
that its indirect ownership interests in the Management Subsidiaries qualify
under the asset tests set forth above. However, no independent appraisals have
been obtained to support AIMCO's conclusions as to the value of the AIMCO
Operating Partnership's total assets and the value of the AIMCO Operating
Partnership's interest in the Management Subsidiaries and these values are
subject to change in the future. Accordingly, there can be no assurance that the
IRS will not contend that the AIMCO Operating Partnership's ownership interests
in the Management Subsidiaries disqualifies AIMCO from treatment as a REIT.
 
     AIMCO's indirect interests in the AIMCO Operating Partnership and other
Subsidiary Partnerships are held through wholly owned corporate subsidiaries of
AIMCO organized and operated as "qualified REIT subsidiaries" within the meaning
of the Code. Qualified REIT subsidiaries are not treated as separate entities
from their parent REIT for federal income tax purposes. Instead, all assets,
liabilities and items of income, deduction and credit of each qualified REIT
subsidiary are treated as assets, liabilities and items of AIMCO. Each qualified
REIT subsidiary therefore is not subject to federal corporate income taxation,
although it may be subject to state or local taxation. In addition, AIMCO's
ownership of the voting stock of each qualified REIT subsidiary does not violate
the general restriction against ownership of more than 10% of the voting
securities of any issuer.
 
  Annual Distribution Requirements
 
     AIMCO, in order to qualify as a REIT, is required to distribute dividends
(other than capital gain dividends) to its stockholders in an amount at least
equal to (A) the sum of (i) 95% of AIMCO's "REIT taxable income" (computed
without regard to the dividends paid deduction and AIMCO's net capital gain) and
(ii) 95% of the net income (after tax), if any, from foreclosure property, minus
(B) the sum of certain items of noncash income. Such distributions must be paid
in the taxable year to which they relate, or in the following taxable year if
declared before AIMCO timely files its tax return for such year and if paid with
or before the first regular dividend payment after such declaration. To the
extent that AIMCO distributes at least 95%, but less than 100%, of its "REIT
taxable income," as adjusted, it will be subject to tax thereon at ordinary
corporate tax rates. AIMCO may elect to retain, rather than distribute, its net
long-term capital gains and pay tax on such gains. In such a case, AIMCO's
stockholders would include their proportionate share of such undistributed
long-term capital gains in income and receive a credit for their share of the
tax paid by AIMCO. AIMCO's stockholders would then increase the adjusted basis
of their AIMCO shares by the difference between the designated amounts included
in their long-term capital gains and the tax deemed paid with respect to their
shares. If AIMCO should fail to distribute during each calendar year at least
the sum of (i) 85% of its REIT ordinary income for such year and (ii) 95% of its
REIT capital gain net income for such
 
                                       70
<PAGE>   179
 
year (excluding retained long-term capital gains), and (iii) any undistributed
taxable income from prior periods, AIMCO would be subject to a 4% excise tax on
the excess of such required distribution over the amounts actually distributed.
AIMCO believes that it has made, and intends to make, timely distributions
sufficient to satisfy these annual distribution requirements.
 
     It is possible that AIMCO, from time to time, may not have sufficient cash
to meet the 95% distribution requirement due to timing differences between (i)
the actual receipt of cash (including receipt of distributions from the AIMCO
Operating Partnership) and (ii) the inclusion of certain items in income by
AIMCO for federal income tax purposes. In the event that such timing differences
occur, in order to meet the 95% distribution requirement, AIMCO may find it
necessary to arrange for short-term, or possibly long-term, borrowings or to pay
dividends in the form of taxable distributions of property.
 
     Under certain circumstances, AIMCO may be able to rectify a failure to meet
the distribution requirement for a year by paying "deficiency dividends" to
stockholders in a later year, which may be included in AIMCO's deduction for
dividends paid for the earlier year. Thus, AIMCO may be able to avoid being
taxed on amounts distributed as deficiency dividends; however, AIMCO will be
required to pay interest and a penalty based on the amount of any deduction
taken for deficiency dividends.
 
  Distribution of Acquired Earnings and Profits
 
     The Code provides that when a REIT acquires a corporation that is currently
a C corporation (i.e., a corporation without a REIT election, such as Insignia),
the REIT may qualify as a REIT only if, as of the close of the year of
acquisition, the REIT has no "earnings and profits" acquired from such C
corporation. In the Insignia Merger, AIMCO will succeed to the earnings and
profits of Insignia and, therefore, AIMCO must distribute such earnings and
profits effective on or before December 31, 1998. Insignia has retained
independent certified public accountants to determine Insignia's earnings and
profits for purposes of this requirement. The determination of the independent
certified public accountants will be based upon Insignia's tax returns as filed
with the IRS and other assumptions and qualifications set forth in the reports
issued by such accountants. Any adjustments to Insignia's income for taxable
years ending on or before the closing of the Insignia Merger, including as a
result of an examination of its returns by the IRS or the receipt of certain
indemnity or other payments, could affect the calculation of Insignia's earnings
and profits. Furthermore, the determination of earnings and profits requires the
resolution of certain technical tax issues with respect to which there is no
authority directly on point and, consequently, the proper treatment of these
issues for earnings and profits purposes is not free from doubt. There can be no
assurance that the IRS will not examine the tax returns of Insignia and propose
adjustments to increase its taxable income and therefore its earnings and
profits. In this regard, the IRS can consider all taxable years of Insignia as
open for review for purposes of determining the amount of such earnings and
profits. Moreover, if the Special Dividend is not treated as a dividend under
the Code, AIMCO may, depending upon the amount of other distributions made by
AIMCO subsequent to the Insignia Merger, fail to distribute an amount equal to
Insignia's earnings and profits. AIMCO's failure to distribute an amount equal
to such earnings and profits effective on or before December 31, 1998, would
result in AIMCO's failure to qualify as a REIT.
 
  Failure to Qualify
 
     If AIMCO fails to qualify for taxation as a REIT in any taxable year, and
the relief provisions do not apply, AIMCO will be subject to tax (including any
applicable alternative minimum tax) on its taxable income at regular corporate
rates. Distributions to stockholders in any year in which AIMCO fails to qualify
will not be deductible by AIMCO nor will they be required to be made. In such
event, to the extent of current and accumulated earnings and profits, all
distributions to stockholders will be taxable as ordinary income, and, subject
to certain limitations of the Code, corporate distributees may be eligible for
the dividends received deduction. Unless AIMCO is entitled to relief under
specific statutory provisions, AIMCO would also be disqualified from taxation as
a REIT for the four taxable years following the year during which qualification
was lost. It is not possible to state whether in all circumstances AIMCO would
be entitled to such statutory relief.

TAX ASPECTS OF AIMCO'S INVESTMENTS IN PARTNERSHIPS
 
  General
 
     Substantially all of AIMCO's investments are held indirectly through the
AIMCO Operating Partnership. In general, partnerships are "pass-through"
entities that are not subject to federal income tax. Rather, partners are
allocated their proportionate shares of the items of income, gain, loss,
deduction and credit of a partnership, and are potentially subject to tax
thereon, without regard to whether the partners receive a distribution from the
partnership. AIMCO will include in its income its proportionate share of the
foregoing partnership items for purposes of the various REIT income tests and in
the computation of its REIT taxable income. Moreover, for purposes of the REIT
asset tests, AIMCO will include its proportionate share of assets held by the
Subsidiary Partnerships. See "-- Federal Income Taxation of AIMCO and AIMCO
Stockholders -- General."
 
  Entity Classification
 
     AIMCO's direct and indirect investment in partnerships involves special tax
considerations, including the possibility of a challenge by the IRS of the
status of any of the Subsidiary Partnerships as a partnership (as opposed to an
association taxable as a corporation) for federal income tax purposes. If any of
these entities were treated as an association for federal income tax purposes,
it would be subject to an entity-level tax on its income. In such a situation,
the character of AIMCO's assets and items of gross income would change and could
preclude AIMCO from satisfying the asset tests and the income tests (see "--
Federal Income Taxation of AIMCO and AIMCO Stockholders -- Asset Tests" and "--
Federal Income Taxation of AIMCO and AIMCO Stockholders -- Income Tests"), and
in turn could prevent AIMCO from qualifying as a REIT. See "-- Federal Income
Taxation of AIMCO and AIMCO Stockholders -- Failure to Qualify" above for a
discussion of the effect of AIMCO's failure to meet such tests for a taxable
year. In addition, any change in the status of any of the Subsidiary
Partnerships for tax purposes might be treated as a taxable event, in which case
AIMCO might incur a tax liability without any related cash distributions.
 
  Tax Allocations with Respect to the Properties
 
     Under the Code and the Treasury Regulations, income, gain, loss and
deduction attributable to appreciated or depreciated property that is
contributed to a partnership in exchange for an interest in the partnership must
be allocated in a manner such that the contributing partner is charged with, or
benefits from, respectively, the unrealized gain or unrealized loss associated
with the property at the time of the contribution. The amount of such unrealized
gain or unrealized loss is generally equal to the difference between the fair
market value of the contributed property at the time of contribution, and the
adjusted tax basis of such property at the time of contribution (a "Book -- Tax
Difference"). Such allocations are solely for federal income tax purposes and do
not affect the book capital accounts or other economic or legal arrangements
among the partners. See "-- Federal Income Taxation of the AIMCO Operating
Partnership and OP Unitholders -- Tax Consequences Upon Contribution of Property
to the AIMCO Operating Partnership." The AIMCO Operating Partnership was formed
by way of contributions of appreciated property (including certain of the Owned
Properties). Consequently, allocations must be made in a manner consistent with
these requirements. Where a partner contributes cash to a partnership that holds
appreciated property, the Treasury Regulations provide for a similar allocation
of such items to the other partners. These rules apply to the contribution by
AIMCO to the AIMCO Operating Partnership of the cash proceeds received in any
offerings of its stock.
 
     In general, certain OP Unitholders will be allocated lower amounts of
depreciation deductions for tax purposes and increased taxable income and gain
on the sale by the AIMCO Operating Partnership or other Subsidiary Partnerships
of the contributed properties. This will tend to eliminate the Book-Tax
Difference over the life of these partnerships. However, the special allocations
do not always entirely rectify the Book-Tax Difference on an annual basis or
with respect to a specific taxable transaction such as a sale. Thus, the
carryover basis of the contributed properties in the hands of the AIMCO
Operating Partnership or other Subsidiary Partnerships may cause AIMCO to be
allocated lower depreciation and other deductions, and
 
                                       72
<PAGE>   181
 
possibly greater amounts of taxable income in the event of a sale of such
contributed assets in excess of the economic or book income allocated to it as a
result of such sale. This may cause AIMCO to recognize taxable income in excess
of cash proceeds, which might adversely affect AIMCO's ability to comply with
the REIT distribution requirements. See "-- Federal Income Taxation of AIMCO and
AIMCO Stockholders -- Annual Distribution Requirements."
 
     With respect to any property purchased or to be purchased by any of the
Subsidiary Partnerships (other than through the issuance of OP Units) subsequent
to the formation of AIMCO, such property will initially have a tax basis equal
to its fair market value and the special allocation provisions described above
will not apply.
 
  Sale of the Properties
 
     AIMCO's share of any gain realized by the AIMCO Operating Partnership or
any other Subsidiary Partnership on the sale of any property held as inventory
or primarily for sale to customers in the ordinary course of business will be
treated as income from a prohibited transaction that is subject to a 100%
penalty tax. See "-- Taxation of AIMCO and AIMCO
Stockholders -- General -- Income Tests." Under existing law, whether property
is held as inventory or primarily for sale to customers in the ordinary course
of a partnership's trade or business is a question of fact that depends on all
the facts and circumstances with respect to the particular transaction. The
AIMCO Operating Partnership and the other Subsidiary Partnerships intend to hold
the Owned Properties for investment with a view to long-term appreciation, to
engage in the business of acquiring, developing, owning and operating the Owned
Properties and to make such occasional sales of the Owned Properties, including
peripheral land, as are consistent with AIMCO's investment objectives.
 
TAXATION OF MANAGEMENT SUBSIDIARIES
 
     A portion of the amounts to be used to fund distributions to stockholders
is expected to come from distributions made by the Management Subsidiaries to
the AIMCO Operating Partnership, and interest paid by the Management
Subsidiaries on certain notes held by the AIMCO Operating Partnership. In
general, the Management Subsidiaries pay federal, state and local income taxes
on their taxable income at normal corporate rates. Any federal, state or local
income taxes that the Management Subsidiaries are required to pay will reduce
AIMCO's cash flow from operating activities and its ability to make payments to
holders of its securities.
 
TAXATION OF TAXABLE DOMESTIC STOCKHOLDERS
 
  Distributions
 
     Provided AIMCO qualifies as a REIT, distributions made to AIMCO's taxable
domestic stockholders out of current or accumulated earnings and profits (and
not designated as capital gain dividends) will be taken into account by them as
ordinary income and will not be eligible for the dividends received deduction
for corporations. Distributions (and retained long-term capital gains) that are
designated as capital gain dividends will be taxed as long-term capital gains
(to the extent that they do not exceed AIMCO's actual net capital gain for the
taxable year) without regard to the period for which the stockholder has held
its stock. However, corporate stockholders may be required to treat up to 20% of
certain capital gain dividends as ordinary income. In addition, net capital
gains attributable to the sale of depreciable real property held for more than
12 months is subject to a 25% maximum federal income tax rate to the extent of
previously claimed real property depreciation.
 
     Distributions in excess of current and accumulated earnings and profits
will not be taxable to a stockholder to the extent that they do not exceed the
adjusted basis of the stockholder's shares in respect of which the distributions
were made, but rather will reduce the adjusted basis of such shares. To the
extent that such distributions exceed the adjusted basis of a stockholder's
shares in respect of which the distributions were made, they will be included in
income as long-term capital gain (or short-term capital gain if the shares have
been held for one year or less) provided that the shares are a capital asset in
the hands of the stockholder. In
 
                                       73
<PAGE>   182
 
addition, any dividend declared by AIMCO in October, November or December of any
year and payable to a stockholder of record on a specified date in any such
month will be treated as both paid by AIMCO and received by the stockholder on
December 31 of such year, provided that the dividend is actually paid by AIMCO
during January of the following calendar year. Stockholders may not include in
their individual income tax returns any net operating losses or capital losses
of AIMCO. In general, any loss upon a sale or exchange of shares by a
stockholder who has held such shares for six months or less (after applying
certain holding period rules) will be treated as a long-term capital loss to the
extent of distributions from AIMCO required to be treated by such stockholder as
long-term capital gain.
 
  Dispositions of AIMCO Stock
 
     In general, under the recently enacted Internal Revenue Service
Restructuring and Reform Act of 1988, capital gains recognized by individuals
and other non-corporate taxpayers upon the sale or disposition of AIMCO Stock
will be subject to a maximum federal income tax rate of 20% if the AIMCO Stock
is held for more than 12 months and will be taxed at ordinary income rates if
the AIMCO Stock is held for 12 months or less. Capital losses recognized by a
stockholder upon the disposition of AIMCO Stock held for more than one year at
the time of disposition will be a long-term capital loss. In addition, any loss
upon a sale or exchange of shares of AIMCO Stock by a stockholder who has held
such shares for six months or less (after applying certain holding period rules)
will be treated as a long-term capital loss to the extent of distributions from
AIMCO required to be treated by such stockholder as long-term capital gain.
 
     A redemption of the Preferred Stock will be treated under Section 302 of
the Code as a dividend subject to tax at ordinary income tax rates (to the
extent of AIMCO's current or accumulated earnings and profits), unless the
redemption satisfies certain tests set forth in Section 302(b) of the Code
enabling the redemption to be treated as a sale or exchange of the Preferred
Stock. The redemption will satisfy such test if it (i) is "substantially
disproportionate" with respect to the holder (which will not be the case if only
the Preferred Stock is redeemed, since it generally does not have voting
rights), (ii) results in a "complete termination" of the holder's stock interest
in AIMCO, or (iii) is "not essentially equivalent to a dividend" with respect to
the holder, all within the meaning of Section 302(b) of the Code. In determining
whether any of these tests have been met, shares considered to be owned by the
holder by reason of certain constructive ownership rules set forth in the Code,
as well as shares actually owned, must generally be taken into account. Because
the determination as to whether any of the alternative tests of Section 302(b)
of the Code is satisfied with respect to any particular holder of the Preferred
Stock will depend upon the facts and circumstances as of the time the
determination is made, prospective investors are advised to consult their own
tax advisors to determine such tax treatment. If a redemption of the Preferred
Stock is treated as a distribution that is taxable as a dividend, the amount of
the distribution would be measured by the amount of cash and the fair market
value of any property received by the stockholders. The stockholder's adjusted
tax basis in such redeemed Preferred Stock would be transferred to the holder's
remaining stockholdings in AIMCO. If, however, the stockholder has no remaining
stockholdings in AIMCO, such basis may, under certain circumstances, be
transferred to a related person or it may be lost entirely.
 
TAXATION OF FOREIGN STOCKHOLDERS
 
     The following is a discussion of certain anticipated U.S. federal income
and estate tax consequences of the ownership and disposition of AIMCO Stock
applicable to Non-U.S. Holders of AIMCO Stock. A "Non-U.S. Holder" is any person
other than (i) a citizen or resident of the United States, (ii) a corporation or
partnership created or organized in the United States or under the laws of the
United States or of any state thereof or the District of Columbia, (iii) an
estate whose income is includible in gross income for U.S. federal income tax
purposes regardless of its source or (iv) a trust if a United States court is
able to exercise primary supervision over the administration of such trust and
one or more United States fiduciaries have the authority to control all
substantial decisions of such trust. The discussion is based on current law and
is for general information only. The discussion addresses only certain and not
all aspects of U.S. federal income and estate taxation.
 
                                       74

  Ordinary Dividends
 
     The portion of dividends received by Non-U.S. Holders payable out of
AIMCO's earnings and profits which are not attributable to capital gains of
AIMCO and which are not effectively connected with a U.S. trade or business of
the Non-U.S. Holder will be subject to U.S. withholding tax at the rate of 30%
(unless reduced by treaty). In general, Non-U.S. Holders will not be considered
engaged in a U.S. trade or business solely as a result of their ownership of
AIMCO Stock. In cases where the dividend income from a Non-U.S. Holder's
investment in AIMCO Stock is (or is treated as) effectively connected with the
Non-U.S. Holder's conduct of a U.S. trade or business, the Non-U.S. Holder
generally will be subject to U.S. tax at graduated rates, in the same manner as
U.S. Holders are taxed with respect to such dividends (and may also be subject
to the 30% branch profits tax in the case of a Non-U.S. Holder that is a
corporation).
 
  Non-Dividend Distributions
 
     Unless AIMCO Stock constitutes a United States Real Property Interest (a
"USRPI"), distributions by AIMCO which are not dividends out of the earnings and
profits of AIMCO will not be subject to U.S. income or withholding tax. If it
cannot be determined at the time a distribution is made whether or not such
distribution will be in excess of current and accumulated earnings and profits,
the distribution will be subject to withholding at the rate applicable to
dividends. However, the Non-U.S. Holder may seek a refund of such amounts from
the IRS if it is subsequently determined that such distribution was, in fact, in
excess of current and accumulated earnings and profits of AIMCO. If AIMCO Stock
constitutes a USRPI, such distributions will be subject to 10% withholding and
taxed pursuant to the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA") at a rate of 35% to the extent such distributions exceed a
stockholder's basis in his or her AIMCO Stock.
 
  Capital Gain Dividends
 
     Under FIRPTA, a distribution made by AIMCO to a Non-U.S. Holder, to the
extent attributable to gains from dispositions of USRPIs such as the properties
beneficially owned by AIMCO ("USRPI Capital Gains"), will be considered
effectively connected with a U.S. trade or business of the Non-U.S. Holder and
subject to U.S. income tax at the rates applicable to U.S. individuals or
corporations, without regard to whether such distribution is designated as a
capital gain dividend. In addition, AIMCO will be required to withhold tax equal
to 35% of the amount of dividends to the extent such dividends constitute USRPI
Capital Gains. Distributions subject to FIRPTA may also be subject to a 30%
branch profits tax in the hands of Non-U.S. Holder that is a corporation.
 
  Dispositions of AIMCO Stock
 
     Unless AIMCO Stock constitutes a USRPI, a sale of such stock by a Non-U.S.
Holder generally will not be subject to U.S. taxation under FIRPTA. The stock
will not constitute a USRPI if AIMCO is a "domestically controlled REIT." A
domestically controlled REIT is a REIT in which, at all times during a specified
testing period, less than 50% in value of its shares is held directly or
indirectly by Non-U.S. Holders. AIMCO believes that it is, and it expects to
continue to be, a domestically controlled REIT and, therefore, the sale of AIMCO
Stock should not be subject to taxation under FIRPTA. Because the Class A Common
Stock is publicly traded, however, no assurance can be given that AIMCO is or
will continue to be a domestically controlled REIT.
 
     If AIMCO does not constitute a domestically controlled REIT, a Non-U.S.
Holder's sale of stock generally will still not be subject to tax under FIRPTA
as a sale of a USRPI provided that (i) the stock is "regularly traded" (as
defined by applicable Treasury Regulations) on an established securities market
(e.g., the NYSE, on which AIMCO Class A Common Stock is listed) and (ii) the
selling Non-U.S. Holder held 5% or less of AIMCO's outstanding stock at all
times during a specified testing period.
 
     If gain on the sale of stock of AIMCO were subject to taxation under
FIRPTA, the Non-U.S. Holder would be subject to the same treatment as a U.S.
stockholder with respect to such gain (subject to applicable alternative minimum
tax and a special alternative minimum tax in the case of nonresident alien
individuals)
 
                                       75
<PAGE>   184
 
and the purchaser of the stock could be required to withhold 10% of the purchase
price and remit such amount to the IRS.
 
     Gain from the sale of AIMCO Stock that would not otherwise be subject to
FIRPTA will nonetheless be taxable in the United States to a Non-U.S. Holder in
two cases: (i) if the Non-U.S. Holder's investment in the AIMCO Stock is
effectively connected with a U.S. trade or business conducted by such Non-U.S.
Holder, the Non-U.S. Holder will be subject to the same treatment as a U.S.
stockholder with respect to such gain, or (ii) if the Non-U.S. Holder is a
nonresident alien individual who was present in the United States for 183 days
or more during the taxable year and has a "tax home" in the United States, the
nonresident alien individual will be subject to a 30% tax on the individual's
capital gain.
 
  Estate Tax
 
     AIMCO Stock owned or treated as owned by an individual who is not a citizen
or resident (as specially defined for U.S. federal estate tax purposes) of the
United States at the time of death will be includible in the individual's gross
estate for U.S. federal estate tax purposes, unless an applicable estate tax
treaty provides otherwise. Such individual's estate may be subject to U.S.
federal estate tax on the property includible in the estate for U.S. federal
estate tax purposes.
 
INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING
 
     AIMCO will report to its U.S. stockholders and to the IRS the amount of
distributions paid during each calendar year, and the amount of tax withheld, if
any. Under the backup withholding rules, a stockholder may be subject to backup
withholding at the rate of 31% with respect to distributions paid unless such
holder (i) is a corporation or comes within certain other exempt categories and,
when required, demonstrates this fact or (ii) provides a taxpayer identification
number, certifies as to no loss of exemption from backup withholding, and
otherwise complies with the applicable requirements of the backup withholding
rules. A stockholder who does not provide AIMCO with his correct taxpayer
identification number also may be subject to penalties imposed by the IRS. Any
amount paid as backup withholding will be creditable against the stockholder's
income tax liability. In addition, AIMCO may be required to withhold a portion
of capital gain distributions to any Non-U.S. Holders who fail to certify their
foreign status to AIMCO. The IRS has issued final Treasury Regulations regarding
the backup withholding rules as applied to Non-U.S. Holders. Those final
Treasury Regulations alter the current system of backup withholding compliance
and will be effective for payments made after December 31, 1999. Prospective
investors in AIMCO Stock should consult their tax advisors regarding the
application of these Treasury Regulations.
 
TAXATION OF TAX-EXEMPT STOCKHOLDERS
 
     Tax-exempt entities, including qualified employee pension and profit
sharing trusts and individual retirement accounts ("Exempt Organizations"),
generally are exempt from federal income taxation. However, they are subject to
taxation on their unrelated business taxable income ("UBTI"). While many
investments in real estate generate UBTI, the IRS has ruled that dividend
distributions from a REIT to an exempt employee pension trust do not constitute
UBTI, provided that the shares of the REIT are not otherwise used in an
unrelated trade or business of the exempt employee pension trust. Based on that
ruling, amounts distributed by AIMCO to Exempt Organizations should generally
not constitute UBTI. However, if an Exempt Organization finances its acquisition
of the AIMCO Stock with debt, a portion of its income from AIMCO will constitute
UBTI pursuant to the "debt-financed property" rules. Furthermore, social clubs,
voluntary employee benefit associations, supplemental unemployment benefit
trusts, and qualified group legal services plans that are exempt from taxation
under paragraphs (7), (9), (17) and (20), respectively, of Section 501(c) of the
Code are subject to different UBTI rules, which generally will require them to
characterize distributions from AIMCO as UBTI. In addition, in certain
circumstances, a pension trust that owns more than 10% of AIMCO's stock is
required to treat a percentage of the dividends from AIMCO as UBTI (the "UBTI
Percentage"). The UBTI Percentage is the gross income derived by AIMCO from an
unrelated trade or business (determined as if AIMCO were a pension trust)
divided by the gross income of AIMCO for the year in which the dividends are
paid. The UBTI rule applies to a pension trust holding more than 10% of
 
                                       76
<PAGE>   185
 
AIMCO's stock only if (i) the UBTI Percentage is at least 5%, (ii) AIMCO
qualifies as a REIT by reason of the modification of the 5/50 Rule that allows
the beneficiaries of the pension trust to be treated as holding shares of AIMCO
in proportion to their actuarial interest in the pension trust, and (iii) either
(A) one pension trust owns more than 25% of the value of AIMCO's stock or (B) a
group of pension trusts each individually holding more than 10% of the value of
AIMCO's stock collectively owns more that 50% of the value of AIMCO's stock. The
restrictions on ownership and transfer of AIMCO's stock should prevent an Exempt
Organization from owning more than 10% of the value of AIMCO's stock.
 
           FEDERAL INCOME TAXATION OF THE AIMCO OPERATING PARTNERSHIP
                               AND OP UNITHOLDERS
 
     The following is a summary of certain federal income tax consequences
resulting from the acquisition of, holding, exchanging, and otherwise disposing
of OP Units. This discussion is based upon the Code, the Treasury Regulations,
rulings issued by the IRS, and judicial decisions, all in effect as of the date
of this Registration Statement and all of which are subject to change, possibly
retroactively. Such summary is also based on the assumptions that the operation
of AIMCO, the AIMCO Operating Partnership and the Subsidiary Partnerships will
be in accordance with their respective organizational documents and partnership
agreements. This summary is for general information only and does not purport to
discuss all aspects of federal income taxation which may be important to a
particular investor in light of its investment or tax circumstances, or to
certain types of investors subject to special tax rules (including financial
institutions, broker-dealers, insurance companies, and, except to the extent
discussed below, tax-exempt organizations and foreign investors, as determined
for United States federal income tax purposes). This summary assumes that
investors will hold their OP Units as "capital assets' (generally, property held
for investment). No advance ruling has been or will be sought from the IRS
regarding any matter discussed in this Registration Statement.
 
     THE FEDERAL INCOME TAX TREATMENT OF HOLDERS OF OP UNITS DEPENDS IN SOME
INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF COMPLEX PROVISIONS OF
FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE
AVAILABLE. ACCORDINGLY, EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF ACQUIRING,
HOLDING, EXCHANGING, OR OTHERWISE DISPOSING OF OP UNITS AND OF AIMCO'S ELECTION
TO BE SUBJECT TO TAX, FOR FEDERAL INCOME TAX PURPOSES, AS A REAL ESTATE
INVESTMENT TRUST.
 
PARTNERSHIP STATUS
 
     AIMCO has received an opinion of Counsel to the effect that the AIMCO
Operating Partnership is classified as a partnership for federal income tax
purposes, and not as an association taxable as a corporation. It must be
emphasized that this opinion of Counsel is based on and conditioned upon ceratin
assumptions and representations and on opinions of local counsel with respect to
matters of local law. The opinion is expressed as of its date and Counsel has no
obligation to advise AIMCO of any subsequent change in matters stated,
represented or assumed or any subsequent change in the applicable law. An
opinion of Counsel is not binding on the IRS, and no assurance can be given that
the IRS will not challenge the status of the AIMCO Operating Partnership as a
partnership.
 
     Some partnerships are, for federal income tax purposes, characterized not
as a partnership but as an association taxable as a corporation or as a
"publicly traded partnership" taxable as a corporation. A partnership will be
classified as a publicly traded partnership if interests therein are traded on
an "established securities market" or are "readily tradable" on a "secondary
market (or the substantial equivalent thereof)."
 
     The AIMCO Operating Partnership believes and intends to take the position
that the AIMCO Operating Partnership should not be classified as a publicly
traded partnership because (i) the OP Units are not traded on an established
securities market and (ii) the OP Units should not be considered readily
tradable on a secondary market or the substantial equivalent thereof. The
determination of whether interests in a partnership are readily tradable on a
secondary market or the substantial equivalent thereof, however, depends
 
                                       77
<PAGE>   186
 
on various facts and circumstances (including facts that are not within the
control of the AIMCO Operating Partnership). Treasury Regulations generally
effective for taxable years beginning after December 31, 1995 (the "PTP
Regulations") provide limited safe harbors, which, if satisfied, will prevent a
partnership's interests from being treated as readily tradable on a secondary
market or the substantial equivalent thereof. Under a grandfather rule, certain
existing partnerships may rely on safe harbors contained in IRS Notice 88-75
rather than on the safe harbors contained in the PTP Regulations for all taxable
years of the partnership beginning before January 1, 2006. The AIMCO Operating
Partnership believes that it is subject to such grandfather rule and that it
cannot rely on the safe harbors contained in the PTP Regulations. The AIMCO
Operating Partnership may not have satisfied any of the safe harbors in Notice
88-75 in its previous tax years. In addition, because the AIMCO Operating
Partnership's ability to satisfy a safe harbor in Notice 88-75 (or to the extent
applicable, a safe harbor in the PTP Regulations) may involve facts that are not
within its control, it is impossible to predict whether the AIMCO Operating
Partnership will satisfy a safe harbor in future tax years. The safe harbors in
Notice 88-75 are not intended to be substantive rules for the determination of
whether partnership interests are readily tradable on a secondary market or the
substantial equivalent thereof, and consequently, the failure to meet these safe
harbors will not necessarily cause the AIMCO Operating Partnership to be treated
as a publicly traded partnership. No assurance can be given, however, that the
IRS will not assert that partnerships such as the AIMCO Operating Partnership
constitute publicly traded partnerships, or that facts and circumstances will
not develop which could result in the AIMCO Operating Partnership being treated
as a publicly traded partnership.
 
     If the AIMCO Operating Partnership were characterized as a publicly traded
partnership, it would nevertheless not be taxable as a corporation as long as
90% or more of its gross income consists of "qualifying income." In general,
qualifying income includes interest, dividends, real property rents (as defined
by section 856 of the Code) and gain from the sale or disposition of real
property. The AIMCO Operating Partnership believes that more than 90% of its
gross income consists of qualifying income and expects that more than 90% of its
gross income in future tax years will consist of qualifying income. In such
event, even if the AIMCO Operating Partnership were characterized as a publicly
traded partnership, it would not be taxable as a corporation. If the AIMCO
Operating Partnership were characterized as a publicly traded partnership,
however, each OP Unitholder would be subject to special rules under section 469
of the Code. See "Limitations on Deductibility of Losses -- Passive Activity
Loss Limitation." No assurance can be given that the actual results of the AIMCO
Operating Partnership's operations for any one taxable year will enable it to
satisfy the qualifying income exception.
 
     If the AIMCO Operating Partnership were characterized as an association or
publicly traded partnership taxable as a corporation (because it did not meet
the qualifying income exception discussed above), it would be subject to tax at
the entity level as a regular corporation and OP Unitholders would be subject to
tax in the same manner as stockholders of a corporation. Thus, the AIMCO
Operating Partnership would be subject to federal tax (and possibly state and
local taxes) on its net income, determined without reduction for any
distributions made to the OP Unitholders, at regular federal corporate income
tax rates, thereby reducing the amount of any cash available for distribution to
the OP Unitholders, which reduction could also materially and adversely impact
the liquidity and value of the OP Units. In addition, the AIMCO Operating
Partnership's items of income, gain, loss, deduction and credit would not be
passed through to the OP Unitholders and the OP Unitholders would not be subject
to tax on the income earned by the AIMCO Operating Partnership. Distributions
received by an OP Unitholder from the AIMCO Operating Partnership, however,
would be treated as dividend income for federal income tax purposes, subject to
tax as ordinary income to the extent of current and accumulated earnings and
profits of the AIMCO Operating Partnership, and the excess, if any, as a
nontaxable return of capital to the extent of the OP Unitholder's adjusted tax
basis in his AIMCO Operating Partnership interest (without taking into account
Partnership liabilities), and thereafter as gain from the sale of a capital
asset. Characterization of the AIMCO Operating Partnership as an association or
publicly traded partnership taxable as a corporation would also result in the
termination of AIMCO's status as a REIT for federal income tax purposes which
would have a material adverse impact on AIMCO. See "Federal Income Taxation of
AIMCO and AIMCO Stockholders -- Tax Aspects of AIMCO's Investments in
Partnerships."
 
                                       78
<PAGE>   187
 
     No assurances can be given that the IRS would not challenge the status of
the AIMCO Operating Partnership as a "partnership" which is not "publicly
traded" for federal income tax purposes or that a court would not reach a result
contrary to such positions. Accordingly, each prospective investor is urged to
consult his tax advisor regarding the classification and treatment of the AIMCO
Operating Partnership as a "partnership" for federal income tax purposes.
 
     The following discussion assumes that the AIMCO Operating Partnership is,
and will continue to be, classified and taxed as a partnership for federal
income tax purposes.
 
TAXATION OF OP UNITHOLDERS
 
     In general, a partnership is treated as a "pass-through" entity for federal
income tax purposes and is not itself subject to federal income taxation. Each
partner of a partnership, however, is subject to tax on his allocable share of
partnership tax items, including partnership income, gains, losses, deductions,
and credits ("Partnership Tax Items") for each taxable year of the partnership
ending within or with such taxable year of the partner, regardless of whether he
receives any actual distributions from the partnership during the taxable year.
Generally, the characterization of any particular Partnership Tax Item is
determined at the partnership, rather than at the partner level, and the amount
of a partner's allocable share of such item is governed by the terms of the
partnership agreement.
 
     No federal income tax will be payable by the AIMCO Operating Partnership.
Instead, each OP Unitholder will be (i) required to include in income his
allocable share of any AIMCO Operating Partnership income or gains and (ii)
entitled to deduct his allocable share of any AIMCO Operating Partnership
deductions or losses, but only to the extent of the OP Unitholder's adjusted tax
basis in his AIMCO Operating Partnership interest and subject to the "at risk"
and "passive activity loss" rules discussed below under the heading "Limitations
on the Deductibility of Losses." An OP Unitholder's allocable share of the AIMCO
Operating Partnership's taxable income may exceed the cash distributions to the
OP Unitholder for any year if the AIMCO Operating Partnership retains its
profits rather than distributing them.
 
ALLOCATIONS OF AIMCO OPERATING PARTNERSHIP PROFITS AND LOSSES
 
     For federal income tax purposes, an OP Unitholder's allocable share of the
AIMCO Operating Partnership's Partnership Tax Items will be determined by the
AIMCO Operating Partnership Agreement if such allocations either have
"substantial economic effect" or are determined to be in accordance with the OP
Unitholder's interests in the AIMCO Operating Partnership. The manner in which
Partnership Tax Items of the AIMCO Operating Partnership are allocated is
described above under the heading "Description of OP Units--Allocations of Net
Income and Net Loss." If the allocations provided by the AIMCO Operating
Partnership Agreement were successfully challenged by the IRS, the
redetermination of the allocations to a particular OP Unitholder for federal
income tax purposes may be less favorable than the allocation set forth in the
AIMCO Operating Partnership Agreement.
 
TAX BASIS OF A PARTNERSHIP INTEREST
 
     A partner's adjusted tax basis in his partnership interest is relevant,
among other things, for determining (i) gain or loss upon a taxable disposition
of his partnership interest, (ii) gain upon the receipt of partnership
distributions, and (iii) the limitations imposed on the use of partnership
deductions and losses allocable to such partner. Generally, the adjusted tax
basis of an OP Unitholder's interest in the AIMCO Operating Partnership is equal
to (A) the sum of the adjusted tax basis of the property contributed by the OP
Unitholder to the AIMCO Operating Partnership in exchange for an interest in the
AIMCO Operating Partnership and the amount of cash, if any, contributed by the
OP Unitholder to the AIMCO Operating Partnership, (B) reduced, but not below
zero, by the OP Unitholder's allocable share of AIMCO Operating Partnership
distributions, deductions, and losses, (C) increased by the OP Unitholder's
allocable share of AIMCO Operating Partnership income and gains, and (D)
increased by the OP Unitholder's allocable share of the AIMCO Operating
Partnership liabilities and decreased by the OP Unitholder's liabilities assumed
by the AIMCO Operating Partnership.
 
                                       79
<PAGE>   188
 
CASH DISTRIBUTIONS
 
     Cash distributions received from a partnership do not necessarily correlate
with income earned by the partnership as determined for federal income tax
purposes. Thus, an OP Unitholder's federal income tax liability in respect of
his allocable share of the AIMCO Operating Partnership taxable income for a
particular taxable year may exceed the amount of cash, if any, received by the
OP Unitholder from the AIMCO Operating Partnership during such year.
 
     If cash distributions, including a "deemed" cash distribution as discussed
below, received by an OP Unitholder in any taxable year exceed his allocable
share of the AIMCO Operating Partnership taxable income for the year, the excess
will constitute, for federal income tax purposes, a return of capital to the
extent of such OP Unitholder's adjusted tax basis in his AIMCO Operating
Partnership interest. Such return of capital will not be includible in the
taxable income of the OP Unitholder, for federal income tax purposes, but it
will reduce, but not below zero, the adjusted tax basis of the AIMCO Operating
Partnership interest held by the OP Unitholder. If an OP Unitholder's tax basis
in his AIMCO Operating Partnership interest is reduced to zero, a subsequent
cash distribution received by the OP Unitholder will be subject to tax as
capital gain income, but only if, and to the extent that, such distribution
exceeds the subsequent positive adjustments, if any, to the tax basis of the OP
Unitholder's AIMCO Operating Partnership interest as determined at the end of
the taxable year during which such distribution is received. A decrease in an OP
Unitholder's share of the AIMCO Operating Partnership liabilities resulting from
the payment or other settlement of such liabilities is generally treated, for
federal income tax purposes, as a deemed cash distribution. A decrease in an OP
Unitholder's percentage interest in the AIMCO Operating Partnership, because of
the issuance by the AIMCO Operating Partnership of additional OP Units, or
otherwise, will decrease an OP Unitholder's share of nonrecourse liabilities of
the AIMCO Operating Partnership, if any, and thus, will result in a
corresponding deemed distribution of cash.
 
     A non-pro rata distribution (or deemed distribution) of money or property
may result in ordinary income to an OP Unitholder, regardless of such OP
Unitholder's tax basis in his OP Units, if the distribution reduces such OP
Unitholder's share of the AIMCO Operating Partnership's "Section 751 Assets."
"Section 751 Assets" are defined by the Code to include "unrealized receivables"
or "substantially appreciated inventory". For this purpose, inventory is
substantially appreciated if its value exceeds 120% of its adjusted basis. Among
other things, "unrealized receivables" include amounts attributable to
previously claimed depreciation deductions on certain types of property. To the
extent that such a reduction in an OP Unitholder's share of Section 751 Assets
occurs, the AIMCO Operating Partnership will be deemed to have distributed a
proportionate share of the Section 751 Assets to the OP Unitholder followed by a
deemed exchange of such assets with the AIMCO Operating Partnership in return
for the non-pro rata portion of the actual distribution made to such OP
Unitholder. This deemed exchange will generally result in the realization of
ordinary income under Section 751(b) by the OP Unitholder. Such income will
equal the excess of (1) the non-pro rata portion of such distribution over (2)
the OP Unitholder's tax basis in such OP Unitholder's share of such Section 751
Assets deemed relinquished in the exchange.
 
TAX CONSEQUENCES UPON CONTRIBUTION OF PROPERTY TO THE AIMCO OPERATING
PARTNERSHIP
 
     Generally, Section 721 of the Code provides that neither the Contributing
Partner nor the AIMCO Operating Partnership will recognize a gain or loss, for
federal income tax purposes, upon a contribution of property to the AIMCO
Operating Partnership in exchange for OP Units. Notwithstanding this general
rule of nonrecognition, the Contributing Partner may recognize a gain where the
property transferred is subject to liabilities, or the AIMCO Operating
Partnership assumes liabilities in connection with a transfer of property, and
the amount of such liabilities exceeds the amount of the AIMCO Operating
Partnership liabilities allocated to the Contributing Partner as determined
immediately after the transfer. Such excess is treated by the Contributing
Partner, for federal income tax purposes, as the receipt of a deemed
distribution of cash to the Contributing Partner from the AIMCO Operating
Partnership. If a person transfers to the AIMCO Operating Partnership an
interest in another partnership (the "Underlying Partnership") in exchange for
an OP Unit, the person will be treated, for federal income tax purposes, as
having transferred to the AIMCO Operating Partnership his allocable share of the
liabilities of the Underlying Partnership, which could result in,
 
                                       80
<PAGE>   189
 
or increase the amount of, a deemed cash distribution. As discussed above, such
deemed cash distributions are generally treated as a nontaxable return of
capital to the extent of the Contributing Partner's adjusted tax basis in his OP
Units and thereafter as gain from the sale of such partnership interest.
 
     If a Contributing Partner receives or is deemed to receive for federal
income tax purposes, cash in addition to OP Units upon the contribution of
property to the AIMCO Operating Partnership, the transaction will likely be
treated as part contribution of property and part sale of property. In such
event, the Contributing Partner will recognize gain or loss with respect to the
portion of the property that is deemed sold to the AIMCO Operating Partnership.
 
     If a Contributing Partner transfers property to the AIMCO Operating
Partnership in exchange for an OP Unit and the adjusted tax basis of such
property differs from its fair market value, AIMCO Operating Partnership Tax
Items must be allocated in a manner such that the Contributing Partner is
charged with, or benefits from, respectively, the unrealized gain or unrealized
loss associated with the property at the time of the contribution. Where a
partner contributes cash to a partnership that holds appreciated property, the
Treasury Regulations provide for a similar allocation of such items to the other
partners. These rules may apply to a contribution by AIMCO to the AIMCO
Operating Partnership of cash proceeds received by AIMCO from the offering of
its stock. Such allocations are solely for federal income tax purposes and do
not affect the book capital accounts or other economic or legal arrangements
among the OP Unitholders. The general purpose underlying this provision is to
specially allocate certain Partnership Tax Items in order to place both the
noncontributing and Contributing Partners in the same tax position that they
would have been in had the Contributing Partner contributed property with an
adjusted tax basis equal its fair market value. Treasury Regulations provide the
AIMCO Operating Partnership with several alternative methods and allow the AIMCO
Operating Partnership to adopt any other reasonable method to make allocations
to reduce or eliminate Book-Tax Differences. The AIMCO GP, in its discretion and
in a manner consistent with the Treasury Regulations, will select and adopt a
method of allocating AIMCO Operating Partnership Tax Items, including the
remedial allocation method, for purposes of eliminating such disparities.
 
     In general, certain OP Unitholders will be allocated lower amounts of
depreciation deductions for tax purposes and increased amounts of taxable income
and gain on the sale by the AIMCO Operating Partnership or other Subsidiary
Partnerships of the contributed properties. Accordingly, in the event the AIMCO
Operating Partnership disposes of contributed property, income attributable to
the Book-Tax Difference of such contributed property generally will be allocated
to the Contributing Partner, and the other OP Unitholders generally will be
allocated only their share of gains attributable to appreciation, if any,
occurring after the contribution of the contributed property. These incremental
allocations of income will not result in additional cash distributions to the
Contributing Partner, with the result that the Contributing Partner may not
necessarily receive cash sufficient to pay the taxes attributable to such
income. These allocations will tend to eliminate the Book-Tax Differences with
respect to the contributed property over the life of the AIMCO Operating
Partnership. However, the special allocation rules of Section 704(c) do not
always entirely rectify the Book-Tax Difference on an annual basis or with
respect to a specific taxable transaction such as a sale. Thus, the carryover
basis of the contributed property in the hands of the AIMCO Operating
Partnership may cause a noncontributing OP Unitholder to be allocated lower
amounts of depreciation and other deductions for tax purposes than would be
allocated to such OP Unitholder if the contributed property had a tax basis
equal to its fair market value at the time of contribution, and possibly to be
allocated taxable gain in the event of a sale of the contributed property in
excess of the economic or book income allocated to it as a result of such sale.
This may cause noncontributing OP Unitholders to recognize taxable income in
excess of cash proceeds.
 
LIMITATIONS ON DEDUCTIBILITY OF LOSSES
 
     Basis Limitation. To the extent that an OP Unitholder's allocable share of
AIMCO Operating Partnership deductions and losses exceeds his adjusted tax basis
in his AIMCO Operating Partnership interest at the end of the of the taxable
year in which the losses and deductions flow through, the excess losses and
deductions cannot be utilized, for federal income tax purposes, by the OP
Unitholder in such year. The excess losses and deductions may, however, be
utilized in the first succeeding taxable year in which, and to the extent
 
                                       81
<PAGE>   190
 
that, there is an increase in the tax basis of the AIMCO Operating Partnership
interest held by such OP Unitholder, but only to the extent permitted under the
"at risk" and "passive activity loss" rules discussed below.
 
     "At Risk" Limitation. Under the "at risk" rules of section 465 of the Code,
a noncorporate taxpayer and a closely held corporate taxpayer are generally not
permitted to claim a deduction, for federal income tax purposes, in respect of a
loss from an activity, whether conducted directly by the taxpayer or through an
investment in a partnership, to the extent that the loss exceeds the aggregate
dollar amount which the taxpayer has "at risk" in such activity at the close of
the taxable year. To the extent that losses are not permitted to be used in any
taxable year, such losses may be carried over to subsequent taxable years and
may be claimed as a deduction by the taxpayer if, and to the extent that, the
amount which the taxpayer has "at risk" is increased. Provided certain
requirements are met, the at risk rules generally do not apply to losses arising
from any activity which constitutes "the holding of real property," which the
holding of an OP Unit should constitute.
 
     "Passive Activity Loss" Limitation. The passive activity loss rules of
section 469 of the Code limit the use of losses derived from passive activities,
which generally includes an investment in limited partnership interests such as
the OP Units. If an investment in an OP Unit is treated as a passive activity,
an OP Unitholder who is an individual investor, as well as certain other types
of investors, would not be able to use losses from the AIMCO Operating
Partnership to offset nonpassive activity income, including salary, business
income, and portfolio income (e.g., dividends, interest, royalties, and gain on
the disposition of portfolio investments) received during the taxable year.
Passive activity losses that are disallowed for a particular taxable year may,
however, be carried forward to offset passive activity income earned by the OP
Unitholder in future taxable years. In addition, such disallowed losses may be
claimed as a deduction, subject to the basis and at risk limitations discussed
above, upon a taxable disposition of an OP Unit by the OP Unitholder, regardless
of whether such OP Unitholder has received any passive activity income during
the year of disposition.
 
     If the AIMCO Operating Partnership were characterized as a publicly traded
partnership, each OP Unitholder would be required to treat any loss derived from
the AIMCO Operating Partnership separately from any income or loss derived from
any other publicly traded partnership, as well as from income or loss derived
from other passive activities. In such case, any net losses or credits
attributable to the AIMCO Operating Partnership which are carried forward may
only be offset against future income of the AIMCO Operating Partnership.
Moreover, unlike other passive activity losses, suspended losses attributable to
the AIMCO Operating Partnership would only be allowed upon the complete
disposition of the OP Unitholder's "entire interest" in the AIMCO Operating
Partnership (rather than upon the disposition of an interest in an "activity").
 
SECTION 754 ELECTION
 
     The AIMCO Operating Partnership has made the election permitted by Section
754 of the Code. Election is irrevocable without the consent of the IRS. The
election will generally permit a purchaser of OP Units, such as AIMCO when it
acquires AIMCO OP Units from OP Unitholders, to adjust its share of the basis in
the AIMCO Operating Partnership's properties pursuant to Section 743(b) of the
Code to fair market value (as reflected by the value of consideration paid for
the OP Units), as if such purchaser had acquired a direct interest in the AIMCO
Operating Partnership assets. The Section 743(b) adjustment is attributed solely
to a purchaser of OP Units and is not added to the bases of the AIMCO Operating
Partnership's assets associated with all of the OP Unitholders in the AIMCO
Operating Partnership.
 
DEPRECIATION
 
     Section 168(i)(7) of the Code provides that in the case of property
transferred to a partnership in a Section 721 transaction, the transferee shall
be treated as the transferor for purposes of computing the depreciation
deduction with respect to so much of the basis in the hands of the transferee as
does not exceed the adjusted basis in the hands of the transferor. The effect of
this rule would be to continue the historic basis, placed in service dates and
methods with respect to the depreciation of the properties being contributed by
a
 
                                       82
<PAGE>   191
 
Contributing Partner to the AIMCO Operating Partnership in exchange for OP
Units. However, an acquiror of OP Units that obtains a Section 743(b) adjustment
by reason of such acquisition (see "Section 754 Election," above) generally will
be allowed depreciation with respect to such adjustment beginning as of the date
of the exchange as if it were new property placed in service as of that date.
 
SALE, REDEMPTION, OR EXCHANGE OF OP UNITS
 
     An OP Unitholder will recognize a gain or loss upon a sale of an OP Unit, a
redemption of an OP Unit for cash, an exchange of an OP Unit for shares of AIMCO
Stock, or other taxable disposition of an OP Unit. Gain or loss recognized upon
a sale or exchange of an OP Unit will be equal to the difference between (i) the
sum of the amount realized in the transaction, which, in the case of the receipt
of shares of AIMCO Stock will be an amount equal to their fair market value at
the time that the transaction is consummated, plus the amount of AIMCO Operating
Partnership liabilities allocable to the OP Unit at such time and (ii) the OP
Unitholder's tax basis in the OP Unit disposed of, which tax basis will be
adjusted for the OP Unitholder's allocable share of the AIMCO Operating
Partnership's income or loss for the taxable year of the disposition. In the
case of a gift of an OP Unit, an OP Unitholder will be deemed to have an amount
realized equal to the amount of the AIMCO Operating Partnership's nonrecourse
liabilities allocable to such OP Unit, and to the extent that the amount
realized exceeds the OP Unitholder's basis for the OP Unit disposed of, such OP
Unitholder will recognize gain for federal income tax purposes. The tax
liability resulting from the gain recognized on a disposition of an OP Unit
could exceed the amount of cash and the fair market value of property received.
 
     If the AIMCO Operating Partnership redeems an OP Unitholder's OP Units for
cash (which is not contributed by AIMCO to effect the redemption), the tax
consequences generally would be the same as described in the preceding
paragraphs, except that if the AIMCO Operating Partnership redeems less than all
of an OP Unitholder's OP Units, the OP Unitholder would recognize no taxable
loss and would recognize taxable gain only to the extent that the cash, plus the
amount of AIMCO Operating Partnership liabilities allocable to the redeemed OP
Units, exceeded the OP Unitholder's adjusted tax basis in all of such OP
Unitholder's OP Units immediately before the redemption.
 
     Under the recently enacted Internal Revenue Service Restructuring and
Reform Act of 1988, capital gains recognized by individuals and certain other
noncorporate taxpayers upon the sale or disposition of an OP Unit will be
subject to a maximum federal income tax rate of 20% if the OP Unit is held for
more than 12 months and will be taxed at ordinary income tax rates if the OP
Unit is held for 12 months or less. Generally, gain or loss recognized by an OP
Unitholder on the sale or other taxable disposition of an OP Unit will be
taxable as capital gain or loss. However, to the extent that the amount realized
upon the sale or other taxable disposition of an OP Unit attributable to an OP
Unitholder's share of "unrealized receivables" of the AIMCO Operating
Partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
amounts attributable to previously claimed depreciation deductions on certain
types of property. In addition, the maximum federal income tax rate for net
capital gains attributable to the sale of depreciable real property (which may
be determined to include an interest in a partnership such as the AIMCO
Operating Partnership) held for more than 12 months is currently 25% (rather
than 20%) to the extent of previously claimed depreciation deductions that would
not be treated as "unrealized receivables."
 
TERMINATION OF THE AIMCO OPERATING PARTNERSHIP
 
     In the event of the dissolution of the AIMCO Operating Partnership, a
distribution of AIMCO Operating Partnership property (other than money and
marketable securities) will not result in taxable gain to an OP Unitholder
(except to the extent provided in Section 737 of the Code for liquidations
occurring within seven years of the date of contribution by an OP Unitholder of
property to the AIMCO Operating Partnership), and the OP Unitholder will hold
such distributed property with a basis equal to the adjusted basis of such OP
Units exchanged therefor, reduced by any money distributed in liquidation.
Further, the liquidation of the AIMCO Operating Partnership will be taxable to a
holder of Units to the extent that the value of any money and marketable
securities distributed in liquidation (including any money deemed distributed as
a result of relief from liabilities) exceeds such OP Unitholder's tax basis in
his OP Units.

ALTERNATIVE MINIMUM TAX
 
     The Code contains different sets of minimum tax rules applicable to
corporate and noncorporate investors. The discussion below relates only to the
alternative minimum tax applicable to noncorporate taxpayers. Accordingly,
corporate investors should consult with their tax advisors with respect to the
effect of the corporate minimum tax provisions that may be applicable to them.
Noncorporate taxpayers are subject to an alternative minimum tax to the extent
the tentative minimum tax ("TMT") exceeds the regular income tax otherwise
payable. The rate of tax imposed on the alternative minimum taxable income
("AMTI") in computing TMT is 26% on the first $175,000 of alternative minimum
taxable income in excess of an exemption amount and 28% on any additional
alternative minimum taxable income of noncorporate investors. In general, AMTI
consists of the taxpayer's taxable income, determined with certain adjustments,
plus his items of tax preference. For example, alternative minimum taxable
income is calculated using an alternative cost recovery (depreciation) system
that is not as favorable as the methods provided for under Section 168 of the
Code which the AIMCO Operating Partnership will use in computing its income for
regular federal income tax purposes. Accordingly, an OP Unitholder's AMTI
derived from the AIMCO Operating Partnership may be higher than such OP
Unitholder's share of the AIMCO Operating Partnership's net taxable income.
Prospective investors should consult with their tax advisors as to the impact of
an investment in OP Units on their liability for the alternative minimum tax.
 
INFORMATION RETURNS AND AUDIT PROCEDURES
 
     The AIMCO Operating Partnership will use all reasonable efforts to furnish
to each OP Unitholder within 90 days after the close of each taxable year of the
AIMCO Operating Partnership, certain tax information, including a Schedule K-1,
which sets forth each OP Unitholder's allocable share of the AIMCO Operating
Partnership's Taxable Items. In preparing this information the AIMCO GP will use
various accounting and reporting conventions to determine the respective OP
Unitholder's allocable share of Partnership Tax Items. There is no assurance
that any such conventions will yield a result which conforms to the requirements
of the Code, the Treasury Regulations or administrative interpretations of the
IRS. The AIMCO GP cannot assure a current or prospective OP Unitholder that the
IRS will not successfully contend in court that such accounting and reporting
conventions are impermissible.
 
     No assurance can be given that the AIMCO Operating Partnership will not be
audited by the IRS or that tax adjustments will not be made. Further, any
adjustments in the AIMCO Operating Partnership's tax returns will lead to
adjustments in OP Unitholders' tax returns and may lead to audits of their
returns and adjustments of items unrelated to the AIMCO Operating Partnership.
Each OP Unitholder would bear the cost of any expenses incurred in connection
with an examination of such OP Unitholder's personal tax return.
 
     Partnerships generally are treated as separate entities for purposes of
federal tax audits, judicial review of administrative adjustments by the IRS and
tax settlement proceedings. The tax treatment of Partnership Tax Items generally
are determined at the partnership level in a unified partnership proceeding
rather than in separate proceedings with the partners. The Code provides for one
partner to be designated as the Tax Matters Partner for these purposes.
 
     The Tax Matters Partner is authorized, but not required, to take certain
actions on behalf of the AIMCO Operating Partnership and OP Unitholders and can
extend the statute of limitations for assessment of tax deficiencies against OP
Unitholders with respect to the AIMCO Operating Partnership Tax Items. The Tax
Matters Partner may bind an OP Unitholder with less than a 1% profits interest
in the AIMCO Operating Partnership to a settlement with the IRS, unless such OP
Unitholder elects, by filing a statement with the IRS, not to give such
authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial
review (to which all the OP Unitholders are bound) of a final partnership
administrative adjustment and, if the Tax Matters Partner fails to seek judicial
review, such review may be sought by any OP Unitholder having at least a 1%
interest in the profits of the AIMCO Operating Partnership or by OP Unitholders
having in the aggregate at least a 5% profits interest. However, only one action
for judicial review will go forward, and each OP Unitholder with an interest in
the outcome may participate.

TAXATION OF FOREIGN OP UNITHOLDERS
 
     A Non-U.S. Holder will be considered to be engaged in a United States trade
or business on account of its ownership of an OP Unit. As a result, a Non-U.S.
Holder will be required to file federal tax returns with respect to its
allocable share of the AIMCO Operating Partnerships income which is effectively
connected to its trade or business. A Non-U.S. Holder that is a corporation may
also be subject to United States branch profit tax at a rate of 30%, in addition
to regular federal income tax, on its allocable share of such income. Such a tax
may be reduced or eliminated by an income tax treaty between the United States
and the country with respect to which the Non-U.S. Holder is resident for tax
purposes. Non-U.S. Holders are advised to consult their tax advisors regarding
the effects an investment in the AIMCO Operating Partnership may have on
information return requirements and other United States and non-United States
tax matters, including the tax consequences of an investment in the AIMCO
Operating Partnership for the country or other jurisdiction of which such
Non-U.S. Holder is a citizen or in which such Non-U.S. Holder resides or is
otherwise located.
 
                             OTHER TAX CONSEQUENCES
 
POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS
 
     The rules dealing with federal income taxation are constantly under review
by persons involved in the legislative process and by the IRS and the U.S.
Treasury Department. Changes to the federal laws and interpretations thereof
could adversely affect an investment in AIMCO or the AIMCO Operating
Partnership. For example, a proposal issued by President Clinton on February 2,
1998, if enacted into law, may adversely affect the ability of AIMCO to expand
the present activities of its Management Subsidiaries. It cannot be predicted
whether, when, in what forms, or with what effective dates, the tax laws
applicable to AIMCO or the AIMCO Operating Partnership, or an investment in
AIMCO or the AIMCO Operating Partnership, will be changed.
 
STATE, LOCAL AND FOREIGN TAXES
 
     The AIMCO Operating Partnership, OP Unitholders, AIMCO and AIMCO
stockholders may be subject to state, local or foreign taxation in various
jurisdictions, including those in which it or they transact business, own
property or reside. It should be noted that the AIMCO Operating Partnership owns
properties located in a number of states and local jurisdictions, and the AIMCO
Operating Partnership and OP Unitholders may be required to file income tax
returns in some or all of those jurisdictions. The state, local or foreign tax
treatment of the AIMCO Operating Partnership and OP Unitholders and of AIMCO and
its stockholders may not conform to the federal income tax consequences
discussed above. Consequently, prospective investors should consult their own
tax advisors regarding the application and effect of state, local foreign tax
laws on an investment in the AIMCO Operating Partnership or AIMCO.

                    SECOND AMENDED AND RESTATED AGREEMENT OF
                 LIMITED PARTNERSHIP OF AIMCO PROPERTIES, L.P.
 
     THIS SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF AIMCO
PROPERTIES, L.P., dated as of July 29, 1994, is entered into by and among
Apartment Investment and Management Company, a Maryland corporation (the
"Previous General Partner"), AIMCO-GP, Inc., a Delaware corporation (the
"General Partner"), AIMCO-LP, Inc., a Delaware corporation (the "Special Limited
Partner"), and the other Limited Partners (as defined below).
 
     WHEREAS, the General Partner has submitted, and the Limited Partners have
approved, an amendment and restatement of the Agreement of Limited Partnership
of AIMCO Properties, L.P. on the terms set forth herein.
 
     NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:
 
   
                                   ARTICLE 1
    
 
                                 DEFINED TERMS
 
     The following definitions shall be for all purposes, unless otherwise
clearly indicated to the contrary, applied to the terms used in this Agreement.
 
     "Act" means the Delaware Revised Uniform Limited Partnership Act, as it may
be amended from time to time, and any successor to such statute.
 
     "Actions" has the meaning set forth in Section 7.7 hereof.
 
     "Additional Funds" has the meaning set forth in Section 4.3.A hereof.
 
     "Additional Limited Partner" means a Person who is admitted to the
Partnership as a Limited Partner pursuant to Section 4.2 and Section 12.2 hereof
and who is shown as such on the books and records of the Partnership.
 
     "Adjusted Capital Account Deficit" means, with respect to any Partner, the
deficit balance, if any, in such Partner's Capital Account as of the end of the
relevant Fiscal Year, after giving effect to the following adjustments:
 
          (i) decrease such deficit by any amounts that such Partner is
     obligated to restore pursuant to this Agreement or by operation of law upon
     liquidation of such Partner's Partnership Interest or is deemed to be
     obligated to restore pursuant to the penultimate sentence of each of
     Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5); and
 
          (ii) increase such deficit by the items described in Regulations
     Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6).
 
The foregoing definition of "Adjusted Capital Account Deficit" is intended to
comply with the provisions of Regulations Section 1.704-1(b)(2)(ii)(d) and shall
be interpreted consistently therewith.
 
     "Adjustment Factor" means 1.0; provided, however, that in the event that:
 
          (i) the Previous General Partner (a) declares or pays a dividend on
     its outstanding REIT Shares in REIT Shares or makes a distribution to all
     holders of its outstanding REIT Shares in REIT Shares, (b) splits or
     subdivides its outstanding REIT Shares or (c) effects a reverse stock split
     or otherwise combines its outstanding REIT Shares into a smaller number of
     REIT Shares, the Adjustment Factor shall be adjusted by multiplying the
     Adjustment Factor previously in effect by a fraction, (i) the numerator of
     which shall be the number of REIT Shares issued and outstanding on the
     record date for such dividend, distribution, split, subdivision, reverse
     split or combination (assuming for such purposes
                                       B-1
<PAGE>   212
 
     that such dividend, distribution, split, subdivision, reverse split or
     combination has occurred as of such time) and (ii) the denominator of which
     shall be the actual number of REIT Shares (determined without the above
     assumption) issued and outstanding on the record date for such dividend,
     distribution, split, subdivision, reverse split or combination;
 
          (ii) the Previous General Partner distributes any rights, options or
     warrants to all holders of its REIT Shares to subscribe for or to purchase
     or to otherwise acquire REIT Shares (or other securities or rights
     convertible into, exchangeable for or exercisable for REIT Shares) at a
     price per share less than the Value of a REIT Share on the record date for
     such distribution (each a "Distributed Right"), then the Adjustment Factor
     shall be adjusted by multiplying the Adjustment Factor previously in effect
     by a fraction (a) the numerator of which shall be the number of REIT Shares
     issued and outstanding on the record date plus the maximum number of REIT
     Shares purchasable under such Distributed Rights and (b) the denominator of
     which shall be the number of REIT Shares issued and outstanding on the
     record date plus a fraction (1) the numerator of which is the maximum
     number of REIT Shares purchasable under such Distributed Rights times the
     minimum purchase price per REIT Share under such Distributed Rights and (2)
     the denominator of which is the Value of a REIT Share as of the record
     date; provided, however, that, if any such Distributed Rights expire or
     become no longer exercisable, then the Adjustment Factor shall be adjusted,
     effective retroactive to the date of distribution of the Distributed
     Rights, to reflect a reduced maximum number of REIT Shares or any change in
     the minimum purchase price for the purposes of the above fraction; and
 
          (iii) the Previous General Partner shall, by dividend or otherwise,
     distribute to all holders of its REIT Shares evidences of its indebtedness
     or assets (including securities, but excluding any dividend or distribution
     referred to in subsection (i) above), which evidences of indebtedness or
     assets relate to assets not received by the Previous General Partner, the
     General Partner and/or the Special Limited Partner pursuant to a pro rata
     distribution by the Partnership, then the Adjustment Factor shall be
     adjusted to equal the amount determined by multiplying the Adjustment
     Factor in effect immediately prior to the close of business on the date
     fixed for determination of shareholders entitled to receive such
     distribution by a fraction (i) the numerator shall be such Value of a REIT
     Share on the date fixed for such determination and (ii) the denominator
     shall be the Value of a REIT Share on the dates fixed for such
     determination less the then fair market value (as determined by the General
     Partner, whose determination shall be conclusive) of the portion of the
     evidences of indebtedness or assets so distributed applicable to one REIT
     Share.
 
Any adjustments to the Adjustment Factor shall become effective immediately
after the effective date of such event, retroactive to the record date, if any,
for such event, provided, however, that any Limited Partner may waive, by
written notice to the General Partner, the effect of any adjustment to the
Adjustment Factor applicable to the Partnership Common Units held by such
Limited Partner, and, thereafter, such adjustment will not be effective as to
such Partnership Common Units. For illustrative purposes, examples of
adjustments to the Adjustment Factor are set forth on Exhibit B attached hereto.
 
     "Affiliate" means, with respect to any Person, any Person directly or
indirectly controlling or controlled by or under common control with such
Person. For the purposes of this definition, "control" when used with respect to
any Person means the possession, directly or indirectly, of the power to direct
or cause the direction of the management and policies of such Person, whether
through the ownership of voting securities, by contract or otherwise, and the
terms "controlling" and "controlled" have meanings correlative to the foregoing.
 
     "Agreement" means this Second Amended and Restated Agreement of Limited
Partnership of AIMCO Properties, L.P., as it may be amended, supplemented or
restated from time to time.
 
     "Applicable Percentage" has the meaning set forth in Section 8.6.B hereof.
 
     "Appraisal" means, with respect to any assets, the written opinion of an
independent third party experienced in the valuation of similar assets, selected
by the General Partner in good faith. Such opinion may
 
                                       B-2
<PAGE>   213
 
be in the form of an opinion by such independent third party that the value for
such property or asset as set by the General Partner is fair, from a financial
point of view, to the Partnership.
 
     "Assignee" means a Person to whom one or more Partnership Common Units have
been Transferred in a manner permitted under this Agreement, but who has not
become a Substituted Limited Partner, and who has the rights set forth in
Section 11.5 hereof.

     profit, cash flows, funds from operations or yield, if any, in respect of
     the Partnership or the General Partner have been made by any Partner or any

                             CAPITAL CONTRIBUTIONS
 
     Section 4.1  Capital Contributions of the Partners. The Partners have
heretofore made Capital Contributions to the Partnership. Each Partner owns
Partnership Units in the amount set forth for such Partner on Exhibit A, as the
same may be amended from time to time by the General Partner to the extent
necessary to reflect accurately sales, exchanges or other Transfers,
redemptions, Capital Contributions, the issuance of additional Partnership
Units, or similar events having an effect on a Partner's ownership of
Partnership Units. Except as provided by law or in Section 4.2, 4.3 or 10.4
hereof, the Partners shall have no obligation or right to make any additional
Capital Contributions or loans to the Partnership.
 
     Section 4.2  Issuances of Additional Partnership Interests.
 
          A. General. The General Partner is hereby authorized to cause the
     Partnership to issue additional Partnership Interests, in the form of
     Partnership Units, for any Partnership purpose, at any time or from time to
     time, to the Partners (including the General Partner and the Special
     Limited Partner) or to other Persons, and to admit such Persons as
     Additional Limited Partners, for such consideration and on such terms and
     conditions as shall be established by the General Partner in its sole and
     absolute discretion, all without the approval of any Limited Partners.
     Without limiting the foregoing, the General Partner is expressly authorized
     to cause the Partnership to issue Partnership Units (i) upon the
     conversion, redemption or exchange of any Debt, Partnership Units or other
     securities issued by the Partnership, (ii) for less than fair market value,
     so long as the General Partner concludes in good faith that such issuance
     is in the best interests of the General Partner and the Partnership, and
     (iii) in connection with any merger of any other Person into the
     Partnership if the applicable merger agreement provides that Persons are to
     receive Partnership Units in exchange for their interests in the Person
     merging into the Partnership. Subject to Delaware law, any additional
     Partnership Interests may be issued in one or more classes, or one or more
     series of any of such classes, with such designations, preferences and
     relative, participating, optional or other special rights, powers and
     duties as shall be determined by the General Partner, in its sole and
     absolute discretion without the approval of any Limited Partner, and set
     forth in a written document thereafter attached to and made an exhibit to
     this Agreement (each, a "Partnership Unit Designation"). Without limiting
     the generality of the foregoing, the General Partner shall have authority
     to specify (a) the allocations of items of Partnership income, gain, loss,
     deduction and credit to each such class or series of Partnership Interests;
     (b) the right of each such class or series of Partnership Interests to
     share in Partnership distributions; (c) the rights of each such class or
     series of Partnership Interests upon dissolution and liquidation of the
     Partnership; (d) the voting rights, if any, of each such class or series of
     Partnership Interests; and (e) the conversion, redemption or exchange
     rights applicable to each such class or series of Partnership Interests.
     Upon the issuance of any additional Partnership Interest, the General
     Partner shall amend Exhibit A as appropriate to reflect such issuance.
 
          B. Issuances to the General Partner or Special Limited Partner. No
     additional Partnership Units shall be issued to the General Partner or the
     Special Limited Partner unless (i) the additional Partnership Units are
     issued to all Partners in proportion to their respective Percentage
     Interests, (ii) (a) the additional Partnership Units are (x) Partnership
     Common Units issued in connection with an issuance of REIT Shares, or (y)
     Partnership Units (other than Partnership Common Units) issued in
     connection with an issuance of Preferred Shares, New Securities or other
     interests in the Previous General Partner (other than REIT Shares), which
     Preferred Shares, New Securities or other interests have designations,
     preferences and other rights, terms and provisions that are substantially
     the same as the designations, preferences and other rights, terms and
     provisions of the additional Partnership Units

                                      B-18
<PAGE>   229
 
     issued to the General Partner or the Special Limited Partner, and (b) the
     General Partner or the Special Limited Partner, as the case may be,
     contributes to the Partnership the cash proceeds or other consideration
     received in connection with the issuance of such REIT Shares, Preferred
     Shares, New Securities or other interests in the Previous General Partner,
     (iii) the additional Partnership Units are issued upon the conversion,
     redemption or exchange of Debt, Partnership Units or other securities
     issued by the Partnership, or (iv) the additional Partnership Units are
     issued pursuant to Section 4.6.
 
          C. No Preemptive Rights. No Person, including, without limitation, any
     Partner or Assignee, shall have any preemptive, preferential, participation
     or similar right or rights to subscribe for or acquire any Partnership
     Interest.
 
     Section 4.3  Additional Funds.
 
          A. General. The General Partner may, at any time and from time to
     time, determine that the Partnership requires additional funds ("Additional
     Funds") for the acquisition or development of additional Properties, for
     the redemption of Partnership Units or for such other purposes as the
     General Partner may determine. Additional Funds may be obtained by the
     Partnership, at the election of the General Partner, in any manner provided
     in, and in accordance with, the terms of this Section 4.3 without the
     approval of any Limited Partners.
 
          B. Additional Capital Contributions. The General Partner, on behalf of
     the Partnership, may obtain any Additional Funds by accepting Capital
     Contributions from any Partners or other Persons and issuing additional
     Partnership Units in consideration therefor.
 
          C. Loans by Third Parties. The General Partner, on behalf of the
     Partnership, may obtain any Additional Funds by causing the Partnership to
     incur Debt to any Person (other than the Previous General Partner, the
     General Partner or the Special Limited Partner) upon such terms as the
     General Partner determines appropriate, including making such Debt
     convertible, redeemable or exchangeable for Partnership Units; provided,
     however, that the Partnership shall not incur any such Debt if (i) a
     breach, violation or default of such Debt would be deemed to occur by
     virtue of the Transfer of any Partnership Interest, or (ii) such Debt is
     recourse to any Partner (unless the Partner otherwise agrees).
 
          D. General Partner Loans. The General Partner, on behalf of the
     Partnership, may obtain any Additional Funds by causing the Partnership to
     incur Debt with the Previous General Partner, the General Partner or the
     Special Limited Partner (each, a "General Partner Loan") if (i) such Debt
     is, to the extent permitted by law, on substantially the same terms and
     conditions (including interest rate, repayment schedule, and conversion,
     redemption, repurchase and exchange rights) as Funding Debt incurred by the
     Previous General Partner, the General Partner or the Special Limited
     Partner, the net proceeds of which are loaned to the Partnership to provide
     such Additional Funds, or (ii) such Debt is on terms and conditions no less
     favorable to the Partnership than would be available to the Partnership
     from any third party; provided, however, that the Partnership shall not
     incur any such Debt if (a) a breach, violation or default of such Debt
     would be deemed to occur by virtue of the Transfer of any Partnership
     Interest, or (b) such Debt is recourse to any Partner (unless the Partner
     otherwise agrees).
 
          E. Issuance of Securities by the Previous General Partner. The
     Previous General Partner shall not issue any additional REIT Shares,
     Preferred Shares, Junior Shares or New Securities unless (i) the Previous
     General Partner contributes the cash proceeds or other consideration
     received from the issuance of such additional REIT Shares, Preferred
     Shares, Junior Shares or New Securities, as the case may be, and from the
     exercise of the rights contained in any such additional New Securities, to
     either or both of the General Partner and the Special Limited Partner, and
     (ii) it or they, as the case may be, contribute such cash proceeds or other
     consideration to the Partnership in exchange for (x) in the case of an
     issuance of REIT Shares, Partnership Common Units, or (y) in the case of an
     issuance of Preferred Shares, Junior Shares or New Securities, Partnership
     Units with designations, preferences and other rights, terms and provisions
     that are substantially the same as the designations, preferences and other
     rights, terms and provisions of such Preferred Shares, Junior Shares or New
     Securities; provided, however, that notwithstanding the foregoing, the
     Previous General Partner may issue REIT Shares,

                                      B-19
<PAGE>   230
 
     Preferred Shares, Junior Shares or New Securities (a) pursuant to Section
     4.4 or Section 8.6.B hereof, (b) pursuant to a dividend or distribution
     (including any stock split) of REIT Shares, Preferred Shares, Junior Shares
     or New Securities to all of the holders of REIT Shares, Preferred Shares,
     Junior Shares or New Securities, as the case may be, (c) upon a conversion,
     redemption or exchange of Preferred Shares, (d) upon a conversion of Junior
     Shares into REIT Shares, (e) upon a conversion, redemption, exchange or
     exercise of New Securities, or (f) in connection with an acquisition of a
     property or other asset to be owned, directly or indirectly, by the
     Previous General Partner if the General Partner determines that such
     acquisition is in the best interests of the Partnership. In the event of
     any issuance of additional REIT Shares, Preferred Shares, Junior Shares or
     New Securities by the Previous General Partner, and the contribution to the
     Partnership, by the General Partner or the Special Limited Partner, of the
     cash proceeds or other consideration received from such issuance, the
     Partnership shall pay the Previous General Partner's expenses associated
     with such issuance, including any underwriting discounts or commissions.
 
     Section 4.4  Stock Option Plans.
 
          A. Options Granted to Company Employees and Independent Directors. If
     at any time or from time to time, in connection with the Previous General
     Partner's Stock Option Plans, a stock option granted to a Company Employee
     or Independent Director is duly exercised:
 
             (1) The Special Limited Partner shall, as soon as practicable after
        such exercise, make a Capital Contribution to the Partnership in an
        amount equal to the exercise price paid to the Previous General Partner
        by such exercising party in connection with the exercise of such stock
        option.
 
             (2) Notwithstanding the amount of the Capital Contribution actually
        made pursuant to Section 4.4.A(1) hereof, the Special Limited Partner
        shall be deemed to have contributed to the Partnership as a Capital
        Contribution, in consideration of an additional Limited Partner Interest
        (expressed in and as additional Partnership Common Units), an amount
        equal to the Value of a REIT Share as of the date of exercise multiplied
        by the number of REIT Shares then being issued in connection with the
        exercise of such stock option.
 
             (3) An equitable Percentage Interest adjustment shall be made in
        which the Special Limited Partner shall be treated as having made a cash
        contribution equal to the amount described in Section 4.4.A(2) hereof.
 
          B. Options Granted to Partnership Employees. If at any time or from
     time to time, in connection with the Previous General Partner's Stock
     Option Plans, a stock option granted to a Partnership Employee is duly
     exercised:
 
             (1) The General Partner shall cause the Previous General Partner to
        sell to the Partnership, and the Partnership shall purchase from the
        Previous General Partner, the number of REIT Shares as to which such
        stock option is being exercised. The purchase price per REIT Share for
        such sale of REIT Shares to the Partnership shall be the Value of a REIT
        Share as of the date of exercise of such stock option.
 
             (2) The Partnership shall sell to the Optionee (or if the Optionee
        is an employee of a Partnership Subsidiary, the Partnership shall sell
        to such Partnership Subsidiary, which in turn shall sell to the
        Optionee), for a cash price per share equal to the Value of a REIT Share
        at the time of the exercise, the number of REIT Shares equal to (a) the
        exercise price paid to the Previous General Partner by the exercising
        party in connection with the exercise of such stock option divided by
        (b) the Value of a REIT Share at the time of such exercise.
 
             (3) The Partnership shall transfer to the Optionee (or if the
        Optionee is an employee of a Partnership Subsidiary, the Partnership
        shall transfer to such Partnership Subsidiary, which in turn shall
        transfer to the Optionee) at no additional cost, as additional
        compensation, the number of REIT Shares equal to the number of REIT
        Shares described in Section 4.4.B(1) hereof less the number of REIT
        Shares described in Section 4.4.B(2) hereof.
 
                                      B-20
<PAGE>   231
 
             (4) The Special Limited Partner shall, as soon as practicable after
        such exercise, make a Capital Contribution to the Partnership of an
        amount equal to all proceeds received (from whatever source, but
        excluding any payment in respect of payroll taxes or other withholdings)
        by the Previous General Partner, the General Partner or the Special
        Limited Partner in connection with the exercise of such stock option. An
        equitable Percentage Interest adjustment shall be made in which the
        Special Limited Partner shall be treated as having made a cash
        contribution equal to the amount described in Section 4.4.B(1) hereof.
 
          C. Special Valuation Rule. For purposes of this Section 4.4, in
     determining the Value of a REIT Share, only the trading date immediately
     preceding the exercise of the relevant stock option under the Previous
     General Partner's Stock Option Plans shall be considered.
 
          D. Future Stock Incentive Plans. Nothing in this Agreement shall be
     construed or applied to preclude or restrain the Previous General Partner,
     the General Partner or the Special Limited Partner from adopting, modifying
     or terminating stock incentive plans, in addition to the Previous General
     Partner's Stock Option Plans, for the benefit of employees, directors or
     other business associates of the Previous General Partner, the General
     Partner, the Special Limited Partner, the Partnership or any of their
     Affiliates. The Limited Partners acknowledge and agree that, in the event
     that any such plan is adopted, modified or terminated by the Previous
     General Partner, the General Partner or the Special Limited Partner
     amendments to this Section 4.4 may become necessary or advisable and that
     any approval or consent to any such amendments requested by the Previous
     General Partner, the General Partner or the Special Limited Partner shall
     not be unreasonably withheld or delayed.
 
     Section 4.5  No Interest; No Return. No Partner shall be entitled to
interest on its Capital Contribution or on such Partner's Capital Account.
Except as provided herein or by law, no Partner shall have any right to demand
or receive the return of its Capital Contribution from the Partnership.
 
     Section 4.6  Conversion of Junior Shares. If, at any time, any of the
Junior Shares are converted into REIT Shares, in whole or in part, then a number
of Partnership Common Units equal to (i) the number of REIT Shares issued upon
such conversion divided by (ii) the Adjustment Factor then in effect shall be
issued to the General Partner and the Special Limited Partner (and between the
General Partner and the Special Limited Partner in proportion to their ownership
of Partnership Common Units immediately preceding such conversion), and the
Percentage Interests of the General Partner and the Limited Partners (including
the Special Limited Partner) shall be adjusted to reflect such conversion.

                                 DISTRIBUTIONS
 
     Section 5.1  Requirement and Characterization of Distributions. Subject to
the terms of any Partnership Unit Designation, the General Partner shall cause
the Partnership to distribute quarterly all, or such portion as the General
Partner may in its sole and absolute discretion determine, of Available Cash
generated by the Partnership during such quarter to the Holders of Partnership
Common Units in accordance with their respective Partnership Common Units held
on such Partnership Record Date. Distributions payable with respect to any
Partnership Units that were not outstanding during the entire quarterly period
in respect of which any distribution is made shall be prorated based on the
portion of the period that such units were outstanding. The General Partner in
its sole and absolute discretion may distribute to the Unitholders Available
Cash on a more frequent basis and provide for an appropriate record date. The
General Partner shall take such reasonable efforts, as determined by it in its
sole and absolute discretion and consistent with the Previous General Partner's
qualification as a REIT, to cause the Partnership to distribute sufficient
amounts to enable (i) the General Partner and the Special Limited Partner to
transfer funds to the Previous General Partner and (ii) the Previous General
Partner to pay shareholder dividends that will (a) satisfy the requirements for
qualifying as a REIT under the Code and Regulations (the "REIT Requirements")
and (b) avoid any federal income or excise tax liability of the Previous General
Partner.

     Section 5.2  Distributions in Kind. No right is given to any Unitholder to
demand and receive property other than cash as provided in this Agreement. The
General Partner may determine, in its sole and absolute discretion, to make a
distribution in kind of Partnership assets to the Unitholders, and such assets
shall be distributed in such a fashion as to ensure that the fair market value
is distributed and allocated in accordance with Articles 5, 6 and 10 hereof.
 
     Section 5.3  Amounts Withheld. All amounts withheld pursuant to the Code or
any provisions of any state or local tax law and Section 10.4 hereof with
respect to any allocation, payment or distribution to any Unitholder shall be
treated as amounts paid or distributed to such Unitholder pursuant to Section
5.1 hereof for all purposes under this Agreement.
 
     Section 5.4  Distributions Upon Liquidation. Notwithstanding the other
provisions of this Article 5, net proceeds from a Terminating Capital
Transaction, and any other cash received or reductions in reserves made after
commencement of the liquidation of the Partnership, shall be distributed to the
Unitholders in accordance with Section 13.2 hereof.
 
     Section 5.5  Restricted Distributions. Notwithstanding any provision to the
contrary contained in this Agreement, neither the Partnership nor the General
Partner, on behalf of the Partnership, shall make a distribution to any
Unitholder on account of its Partnership Interest or interest in Partnership
Units if such distribution would violate Section 17-607 of the Act or other
applicable law.

                                  ALLOCATIONS
 
     Section 6.1  Timing and Amount of Allocations of Net Income and Net
Loss. Net Income and Net Loss of the Partnership shall be determined and
allocated with respect to each Fiscal Year of the Partnership as of the end of
each such year. Except as otherwise provided in this Article 6, and subject to
Section 11.6.C hereof, an allocation to a Unitholder of a share of Net Income or
Net Loss shall be treated as an allocation of the same share of each item of
income, gain, loss or deduction that is taken into account in computing Net
Income or Net Loss.
 
     Section 6.2  General Allocations. Subject to the terms of any Partnership
Unit Designation, except as otherwise provided in this Article 6 and subject to
Section 11.6.C hereof, Net Income and Net Loss shall be allocated to each of the
Holders of Partnership Common Units in accordance with their respective
Partnership Common Units at the end of each Fiscal Year.
 
     Section 6.3  Additional Allocation Provisions. Notwithstanding the
foregoing provisions of this Article 6:
 
          A. Intentionally Omitted.
 
          B. Regulatory Allocations.
 
             (i) Minimum Gain Chargeback. Except as otherwise provided in
        Regulations Section 1.704-2(f), notwithstanding the provisions of
        Section 6.2 hereof, or any other provision of this Article 6, if there
        is a net decrease in Partnership Minimum Gain during any Fiscal Year,
        each Holder of Partnership Common Units shall be specially allocated
        items of Partnership income and gain for such year (and, if necessary,
        subsequent years) in an amount equal to such Holder's share of the net
        decrease in Partnership Minimum Gain, as determined under Regulations
        Section 1.704-2(g). Allocations pursuant to the previous sentence shall
        be made in proportion to the respective amounts required to be allocated
        to each Holder pursuant thereto. The items to be allocated shall be
        determined in accordance with Regulations Sections 1.704-2(f)(6) and
        1.704-2(j)(2). This Section 6.3.B(i) is intended to qualify as a
        "minimum gain chargeback" within the meaning of Regulations Section
        1.704-2(f) and shall be interpreted consistently therewith.
 
             (ii) Partner Minimum Gain Chargeback. Except as otherwise provided
        in Regulations Section 1.704-2(i)(4) or in Section 6.3.B(i) hereof, if
        there is a net decrease in Partner Minimum Gain

                                      B-22

        attributable to a Partner Nonrecourse Debt during any Fiscal Year, each
        Holder of Partnership Common Units who has a share of the Partner
        Minimum Gain attributable to such Partner Nonrecourse Debt, determined
        in accordance with Regulations Section 1.704-2(i)(5), shall be specially
        allocated items of Partnership income and gain for such year (and, if
        necessary, subsequent years) in an amount equal to such Holder's share
        of the net decrease in Partner Minimum Gain attributable to such Partner
        Nonrecourse Debt, determined in accordance with Regulations Section
        1.7042(i)(4). Allocations pursuant to the previous sentence shall be
        made in proportion to the respective amounts required to be allocated to
        each General Partner, Limited Partner and other Holder pursuant thereto.
        The items to be so allocated shall be determined in accordance with
        Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section
        6.3.B(ii) is intended to qualify as a "chargeback of partner nonrecourse
        debt minimum gain" within the meaning of Regulations Section 1.704-2(i)
        and shall be interpreted consistently therewith.
 
             (iii) Nonrecourse Deductions and Partner Nonrecourse
        Deductions. Any Nonrecourse Deductions for any Fiscal Year shall be
        specially allocated to the Holders of Partnership Common Units in
        accordance with their Partnership Common Units. Any Partner Nonrecourse
        Deductions for any Fiscal Year shall be specially allocated to the
        Holder(s) who bears the economic risk of loss with respect to the
        Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions
        are attributable, in accordance with Regulations Section 1.704-2(i).
 
             (iv) Qualified Income Offset. If any Holder of Partnership Common
        Units unexpectedly receives an adjustment, allocation or distribution
        described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6),
        items of Partnership income and gain shall be allocated, in accordance
        with Regulations Section 1.704-1(b)(2)(ii)(d), to such Holder in an
        amount and manner sufficient to eliminate, to the extent required by
        such Regulations, the Adjusted Capital Account Deficit of such Holder as
        quickly as possible, provided that an allocation pursuant to this
        Section 6.3.B(iv) shall be made if and only to the extent that such
        Holder would have an Adjusted Capital Account Deficit after all other
        allocations provided in this Article 6 have been tentatively made as if
        this Section 6.3.B(iv) were not in the Agreement. It is intended that
        this Section 6.3.B(iv) qualify and be construed as a "qualified income
        offset" within the meaning of Regulations Section 1.704-1(b)(2)(ii)(d)
        and shall be interpreted consistently therewith.
 
             (v) Gross Income Allocation. In the event that any Holder of
        Partnership Common Units has a deficit Capital Account at the end of any
        Fiscal Year that is in excess of the sum of (1) the amount (if any) that
        such Holder is obligated to restore to the Partnership upon complete
        liquidation of such Holder's Partnership Interest (including, the
        Holder's interest in outstanding Partnership Preferred Units and other
        Partnership Units) and (2) the amount that such Holder is deemed to be
        obligated to restore pursuant to the penultimate sentences of
        Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Holder
        shall be specially allocated items of Partnership income and gain in the
        amount of such excess to eliminate such deficit as quickly as possible,
        provided that an allocation pursuant to this Section 6.3.B(v) shall be
        made if and only to the extent that such Holder would have a deficit
        Capital Account in excess of such sum after all other allocations
        provided in this Article 6 have been tentatively made as if this Section
        6.3.B(v) and Section 6.3.B(iv) hereof were not in the Agreement.
 
             (vi) Limitation on Allocation of Net Loss. To the extent that any
        allocation of Net Loss would cause or increase an Adjusted Capital
        Account Deficit as to any Holder of Partnership Common Units, such
        allocation of Net Loss shall be reallocated among the other Holders of
        Partnership Common Units in accordance with their respective Partnership
        Common Units, subject to the limitations of this Section 6.3.B(vi).
 
             (vii) Section 754 Adjustment. To the extent that an adjustment to
        the adjusted tax basis of any Partnership asset pursuant to Code Section
        734(b) or Code Section 743(b) is required, pursuant to Regulations
        Section 1.704-1(b)(2) (iv)(m)(2) or Regulations Section
        1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital
        Accounts as the
 
                                      B-23
<PAGE>   234
 
        result of a distribution to a Holder of Partnership Common Units in
        complete liquidation of its interest in the Partnership, the amount of
        such adjustment to the Capital Accounts shall be treated as an item of
        gain (if the adjustment increases the basis of the asset) or loss (if
        the adjustment decreases such basis), and such gain or loss shall be
        specially allocated to the Holders in accordance with their Partnership
        Common Units in the event that Regulations Section
        1.704-1(b)(2)(iv)(m)(2) applies, or to the Holders to whom such
        distribution was made in the event that Regulations Section
        1.704-1(b)(2)(iv)(m)(4) applies.
 
             (viii) Curative Allocations. The allocations set forth in Sections
        6.3.B(i), (ii), (iii), (iv), (v), (vi) and (vii) hereof (the "Regulatory
        Allocations") are intended to comply with certain regulatory
        requirements, including the requirements of Regulations Sections
        1.704-1(b) and 1.704-2. Notwithstanding the provisions of Section 6.1
        hereof, the Regulatory Allocations shall be taken into account in
        allocating other items of income, gain, loss and deduction among the
        Holders of Partnership Common Units so that to the extent possible
        without violating the requirements giving rise to the Regulatory
        Allocations, the net amount of such allocations of other items and the
        Regulatory Allocations to each Holder of a Partnership Common Unit shall
        be equal to the net amount that would have been allocated to each such
        Holder if the Regulatory Allocations had not occurred.
 
          C. Special Allocations Upon Liquidation. Notwithstanding any provision
     in this Article VI to the contrary, in the event that the Partnership
     disposes of all or substantially all of its assets in a transaction that
     will lead to a liquidation of the Partnership pursuant to Article XIII
     hereof, then any Net Income or Net Loss realized in connection with such
     transaction and thereafter (and, if necessary, constituent items of income,
     gain, loss and deduction) shall be specially allocated among the Partners
     as required so as to cause liquidating distributions pursuant to Section
     13.2.A(4) hereof to be made in the same amounts and proportions as would
     have resulted had such distributions instead been made pursuant to Section
     5.1 hereof.
 
          D. Allocation of Excess Nonrecourse Liabilities. For purposes of
     determining a Holder's proportional share of the "excess nonrecourse
     liabilities" of the Partnership within the meaning of Regulations Section
     1.752-3(a)(3), each Holder's interest in Partnership profits shall be such
     Holder's share of Partnership Common Units.
 
     Section 6.4  Tax Allocations.
 
          A. In General. Except as otherwise provided in this Section 6.4, for
     income tax purposes under the Code and the Regulations each Partnership
     item of income, gain, loss and deduction (collectively, "Tax Items") shall
     be allocated among the Holders of Partnership Common Units in the same
     manner as its correlative item of "book" income, gain, loss or deduction is
     allocated pursuant to Sections 6.2 and 6.3 hereof.
 
          B. Allocations Respecting Section 704(c) Revaluations. Notwithstanding
     Section 6.4.A hereof, Tax Items with respect to Property that is
     contributed to the Partnership with a Gross Asset Value that varies from
     its basis in the hands of the contributing Partner immediately preceding
     the date of contribution shall be allocated among the Holders of
     Partnership Common Units for income tax purposes pursuant to Regulations
     promulgated under Code Section 704(c) so as to take into account such
     variation. The Partnership shall account for such variation under any
     method approved under Code Section 704(c) and the applicable Regulations as
     chosen by the General Partner, including, without limitation, the
     "traditional method" as described in Regulations Section 1.704-3(b). In the
     event that the Gross Asset Value of any partnership asset is adjusted
     pursuant to subsection (b) of the definition of "Gross Asset Value"
     (provided in Article 1 hereof), subsequent allocations of Tax Items with
     respect to such asset shall take account of the variation, if any, between
     the adjusted basis of such asset and its Gross Asset Value in the same
     manner as under Code Section 704(c) and the applicable Regulations.

        payment of any federal income tax (including, for this purpose, any
        excise tax pursuant to Code Section 4981) and to make distributions to
        its shareholders sufficient to permit the Previous General Partner to
        maintain REIT status or otherwise to satisfy the REIT Requirements), the
        assumption or guarantee of, or other contracting for, indebtedness and
        other liabilities, the issuance of evidences of indebtedness (including

        activities of the General Partner, the Partnership or any of the
        Partnership's Subsidiaries, the lending of funds to other Persons
        (including, without limitation, the Partnership's Subsidiaries) and the
        repayment of obligations of the Partnership, its Subsidiaries and any
        other Person in which it has an equity investment, and the making of
        capital contributions to and equity investments in the Partnership's

        this Agreement, including contracting with contractors, developers,

             (7) the distribution of Partnership cash or other Partnership

             (9) the maintenance of such insurance for the benefit of the
        Partnership and the Partners as it deems necessary or appropriate;

        the acquisition of interests in, and the contributions of property to,
        any Subsidiary and any other Person in which it has an equity investment
        from time to time); provided, however, that, as long as the Previous
        General Partner has determined to continue to qualify as a REIT, the
        General Partner may not engage in any such formation, acquisition or
        contribution that would cause the Previous General Partner to fail to
        qualify as a REIT or the General Partner to fail to qualify as a

        856(i)(2);
 
             (11) the control of any matters affecting the rights and
        obligations of the Partnership, including the settlement, compromise,
        submission to arbitration or any other form of dispute resolution, or
        abandonment, of any claim, cause of action, liability, debt or damages,

        suits, legal proceedings, administrative proceedings, arbitrations or
        other forms of dispute resolution, and the representation of the

        indemnities, waivers, releases or legal instruments or agreements in
        writing necessary or appropriate in the judgment of the General Partner
        for the accomplishment of any of the powers of the General Partner
        enumerated in this Agreement;
 
             (19) the issuance of additional Partnership Units, as appropriate
        and in the General Partner's sole and absolute discretion, in connection
        with Capital Contributions by Additional Limited Partners and additional
        Capital Contributions by Partners pursuant to Article 4 hereof; and
 
             (20) an election to dissolve the Partnership pursuant to Section
        13.1.C hereof.
 
          B. Each of the Limited Partners agrees that, except as provided in
     Section 7.3 hereof, the General Partner is authorized to execute, deliver
     and perform the above-mentioned agreements and transactions on behalf of
     the Partnership without any further act, approval or vote of the Partners,
     notwithstanding any other provision of this Agreement (except as provided
     in Section 7.3 hereof), the Act or any applicable law, rule or regulation.
     The execution, delivery or performance by the General Partner or the
     Partnership of any agreement authorized or permitted under this Agreement
     shall not constitute a breach by the General Partner of any duty that the
     General Partner may owe the Partnership or the Limited Partners or any
     other Persons under this Agreement or of any duty stated or implied by law
     or equity.
 
          C. At all times from and after the date hereof, the General Partner
     may cause the Partnership to obtain and maintain (i) casualty, liability
     and other insurance on the Properties of the Partnership and (ii) liability
     insurance for the Indemnitees hereunder.
 
          D. At all times from and after the date hereof, the General Partner
     may cause the Partnership to establish and maintain working capital and
     other reserves in such amounts as the General Partner, in its sole and
     absolute discretion, deems appropriate and reasonable from time to time.
 
          E. In exercising its authority under this Agreement, the General
     Partner may, but shall be under no obligation to, take into account the tax
     consequences to any Partner (including the General Partner) of any action
     taken by it. The General Partner and the Partnership shall not have
     liability to a Limited Partner under any circumstances as a result of an
     income tax liability incurred by such Limited Partner as a result of an
     action (or inaction) by the General Partner pursuant to its authority under
     this Agreement so long as the action or inaction is taken in good faith.
 
     Section 7.2  Certificate of Limited Partnership. To the extent that such
action is determined by the General Partner to be reasonable and necessary or
appropriate, the General Partner shall file amendments to and restatements of
the Certificate and do all the things to maintain the Partnership as a limited
partnership (or a partnership in which the limited partners have limited
liability) under the laws of the State of Delaware and each other state, the
District of Columbia or any other jurisdiction, in which the Partnership may
elect to do business or own property. Subject to the terms of Section 8.5.A(4)
hereof, the General Partner shall not be required, before or after filing, to
deliver or mail a copy of the Certificate or any amendment thereto to any
Limited Partner. The General Partner shall use all reasonable efforts to cause
to be filed such other certificates or documents as may be reasonable and
necessary or appropriate for the formation, continuation, qualification and
operation of a limited partnership (or a partnership in which the limited
partners have limited liability to the extent provided by applicable law) in the
State of Delaware and any other state, or the District of Columbia or other
jurisdiction, in which the Partnership may elect to do business or own property.
 
     Section 7.3  Restrictions on General Partner's Authority.
 
          A. The General Partner may not take any action in contravention of
     this Agreement, including, without limitation:
 
             (1) take any action that would make it impossible to carry on the
        ordinary business of the Partnership, except as otherwise provided in
        this Agreement;
 
             (2) possess Partnership property, or assign any rights in specific
        Partnership property, for other than a Partnership purpose except as
        otherwise provided in this Agreement;

             (3) admit a Person as a Partner, except as otherwise provided in
        this Agreement;
 
             (4) perform any act that would subject a Limited Partner to
        liability as a general partner in any jurisdiction or any other
        liability except as provided herein or under the Act; or
 
             (5) enter into any contract, mortgage, loan or other agreement that
        prohibits or restricts, or has the effect of prohibiting or restricting,
        the ability of (a) the General Partner, the Previous General Partner or
        the Partnership from satisfying its obligations under Section 8.6 hereof
        in full or (b) a Limited Partner from exercising its rights under
        Section 8.6 hereof to effect a Redemption in full, except, in either
        case, with the written consent of such Limited Partner affected by the
        prohibition or restriction.
 
          B. The General Partner shall not, without the prior Consent of the
     Limited Partners, undertake, on behalf of the Partnership, any of the
     following actions or enter into any transaction that would have the effect
     of such transactions:
 
             (1) except as provided in Section 7.3.C hereof, amend, modify or
        terminate this Agreement other than to reflect the admission,
        substitution, termination or withdrawal of Partners pursuant to Article
        11 or Article 12 hereof;
 
             (2) make a general assignment for the benefit of creditors or
        appoint or acquiesce in the appointment of a custodian, receiver or
        trustee for all or any part of the assets of the Partnership;
 
             (3) institute any proceeding for bankruptcy on behalf of the
        Partnership; or
 
             (4) subject to the rights of Transfer provided in Sections 11.1.C
        and 11.2 hereof, approve or acquiesce to the Transfer of the Partnership
        Interest of the General Partner, or admit into the Partnership any
        additional or successor General Partners.
 
          C. Notwithstanding Section 7.3.B hereof, the General Partner shall
     have the power, without the Consent of the Limited Partners, to amend this
     Agreement as may be required to facilitate or implement any of the
     following purposes:
 
             (1) to add to the obligations of the General Partner or surrender
        any right or power granted to the General Partner or any Affiliate of
        the General Partner for the benefit of the Limited Partners;
 
             (2) to reflect the admission, substitution or withdrawal of
        Partners or the termination of the Partnership in accordance with this
        Agreement, and to amend Exhibits A and C in connection with such
        admission, substitution or withdrawal;
 
             (3) to reflect a change that is of an inconsequential nature and
        does not adversely affect the Limited Partners in any material respect,
        or to cure any ambiguity, correct or supplement any provision in this
        Agreement not inconsistent with law or with other provisions, or make
        other changes with respect to matters arising under this Agreement that
        will not be inconsistent with law or with the provisions of this
        Agreement;
 
             (4) to satisfy any requirements, conditions or guidelines contained
        in any order, directive, opinion, ruling or regulation of a federal or
        state agency or contained in federal or state law;
 
             (5) (a) to reflect such changes as are reasonably necessary (i) for
        either the General Partner or the Special Limited Partner, as the case
        may be, to maintain its status as a "qualified REIT subsidiary" within
        the meaning of Code Section 856(i)(2) or (ii) for the Previous General
        Partner to maintain its status as a REIT or to satisfy the REIT
        Requirement; (b) to reflect the Transfer of all or any part of a
        Partnership Interest among the Previous General Partner, the General
        Partner, the Special Limited Partner or any other "qualified REIT
        subsidiary" (within the meaning of Code Section 856(i)(2)) with respect
        to the Previous General Partner;
 
             (6) to modify the manner in which Capital Accounts are computed
        (but only to the extent set forth in the definition of "Capital Account"
        or contemplated by the Code or the Regulations); and
 
                                      B-28
<PAGE>   239
 
             (7) the issuance of additional Partnership Interests in accordance
        with Section 4.2.
 
     The General Partner will provide notice to the Limited Partners when any
     action under this Section 7.3.C is taken.
 
          D. Notwithstanding Sections 7.3.B and 7.3.C hereof, this Agreement
     shall not be amended, and no action may be taken by the General Partner,
     without the Consent of each Partner adversely affected, if such amendment
     or action would (i) convert a Limited Partner Interest in the Partnership
     into a General Partner Interest (except as a result of the General Partner
     acquiring such Partnership Interest), (ii) modify the limited liability of
     a Limited Partner, (iii) alter the rights of any Partner to receive the
     distributions to which such Partner is entitled, pursuant to Article 5 or
     Section 13.2.A(4) hereof, or alter the allocations specified in Article 6
     hereof (except, in any case, as permitted pursuant to Sections 4.2 and
     7.3.C hereof), (iv) alter or modify the Redemption rights, Cash Amount or
     REIT Shares Amount as set forth in Sections 8.6 and 11.2 hereof, or amend
     or modify any related definitions, or (v) amend this Section 7.3.D;
     provided, however, that the Consent of each Partner adversely affected
     shall not be required for any amendment or action that affects all Partners
     holding the same class or series of Partnership Units on a uniform or pro
     rata basis. Further, no amendment may alter the restrictions on the General
     Partner's authority set forth elsewhere in this Section 7.3 without the
     Consent specified therein. Any such amendment or action consented to by any
     Partner shall be effective as to that Partner, notwithstanding the absence
     of such consent by any other Partner.
 
     Section 7.4  Reimbursement of the General Partner.
 
          A. The General Partner shall not be compensated for its services as
     general partner of the Partnership except as provided in elsewhere in this
     Agreement (including the provisions of Articles 5 and 6 hereof regarding
     distributions, payments and allocations to which it may be entitled in its
     capacity as the General Partner).
 
          B. Subject to Sections 7.4.C and 15.11 hereof, the Partnership shall
     be liable for, and shall reimburse the General Partner on a monthly basis,
     or such other basis as the General Partner may determine in its sole and
     absolute discretion, for all sums expended in connection with the
     Partnership's business, including, without limitation, (i) expenses
     relating to the ownership of interests in and management and operation of,
     or for the benefit of, the Partnership, (ii) compensation of officers and
     employees, including, without limitation, payments under future
     compensation plans of the General Partner that may provide for stock units,
     or other phantom stock, pursuant to which employees of the General Partner
     will receive payments based upon dividends on or the value of REIT Shares,
     (iii) director fees and expenses and (iv) all costs and expenses of the
     General Partner being a public company, including costs of filings with the
     SEC, reports and other distributions to its shareholders; provided,
     however, that the amount of any reimbursement shall be reduced by any
     interest earned by the General Partner with respect to bank accounts or
     other instruments or accounts held by it on behalf of the Partnership as
     permitted pursuant to Section 7.5 hereof. Such reimbursements shall be in
     addition to any reimbursement of the General Partner as a result of
     indemnification pursuant to Section 7.7 hereof.
 
          C. To the extent practicable, Partnership expenses shall be billed
     directly to and paid by the Partnership and, subject to Section 15.11
     hereof, reimbursements to the General Partner or any of its Affiliates by
     the Partnership pursuant to this Section 7.4 shall be treated as
     "guaranteed payments" within the meaning of Code Section 707(c).
 
     Section 7.5  Outside Activities of the Previous General Partner and the
General Partner. Neither the General Partner nor the Previous General Partner
shall directly or indirectly enter into or conduct any business, other than in
connection with (a) the ownership, acquisition and disposition of Partnership
Interests as General Partner, (b) the management of the business of the
Partnership, (c) the operation of the Previous General Partner as a reporting
company with a class (or classes) of securities registered under the Exchange
Act, (d) the Previous General Partner's operations as a REIT, (e) the offering,
sale, syndication, private placement or public offering of stock, bonds,
securities or other interests, (f) financing or refinancing of any
 
                                      B-29
<PAGE>   240
 
type related to the Partnership or its assets or activities, (g) the General
Partner's qualification as a "qualified REIT subsidiary" (within the meaning of
Code Section 856(i)(2)) and (h) such activities as are incidental thereto.
Nothing contained herein shall be deemed to prohibit the General Partner or the
Previous General Partner from executing guarantees of Partnership debt for which
it would otherwise be liable in its capacity as General Partner. Subject to
Section 7.3.B hereof, the General Partner, the Previous General Partner, the
Special Limited Partner and all "qualified REIT subsidiaries" (within the
meaning of Code Section 856(i)(2)), taken as a group, shall not own any assets
or take title to assets (other than temporarily in connection with an
acquisition prior to contributing such assets to the Partnership) other than
Partnership Interests as the General Partner or Special Limited Partner and
other than such cash and cash equivalents, bank accounts or similar instruments
or accounts as such group deems reasonably necessary, taking into account
Section 7.1.D hereof and the requirements necessary for the Previous General
Partner to qualify as a REIT and for the Previous General Partner, the General
Partner and the Special Limited Partner to carry out their respective
responsibilities contemplated under this Agreement and the Charter.
Notwithstanding the foregoing, if the Previous General Partner or the General
Partner acquires assets in its own name and owns Property other than through the
Partnership, the Partners agree to negotiate in good faith to amend this
Agreement, including, without limitation, the definition of "Adjustment Factor,"
to reflect such activities and the direct ownership of assets by the Previous
General Partner or the General Partner. The General Partner and any Affiliates
of the General Partner may acquire Limited Partner Interests and shall be
entitled to exercise all rights of a Limited Partner relating to such Limited
Partner Interests.
 
     Section 7.6  Contracts with Affiliates.
 
          A. The Partnership may lend or contribute funds or other assets to its
     Subsidiaries or other Persons in which it has an equity investment, and
     such Persons may borrow funds from the Partnership, on terms and conditions
     established in the sole and absolute discretion of the General Partner. The
     foregoing authority shall not create any right or benefit in favor of any
     Subsidiary or any other Person.
 
          B. Except as provided in Section 7.5 hereof and subject to Section 3.1
     hereof, the Partnership may transfer assets to joint ventures, limited
     liability companies, partnerships, corporations, business trusts or other
     business entities in which it is or thereby becomes a participant upon such
     terms and subject to such conditions consistent with this Agreement and
     applicable law as the General Partner, in its sole and absolute discretion,
     believes to be advisable.
 
          C. Except as expressly permitted by this Agreement, neither the
     General Partner nor any of its Affiliates shall sell, transfer or convey
     any property to the Partnership, directly or indirectly, except pursuant to
     transactions that are determined by the General Partner in good faith to be
     fair and reasonable.
 
          D. The General Partner, in its sole and absolute discretion and
     without the approval of the Limited Partners, may propose and adopt on
     behalf of the Partnership employee benefit plans funded by the Partnership
     for the benefit of employees of the General Partner, the Partnership,
     Subsidiaries of the Partnership or any Affiliate of any of them in respect
     of services performed, directly or indirectly, for the benefit of the
     Partnership or any of the Partnership's Subsidiaries.
 
          E. The General Partner is expressly authorized to enter into, in the
     name and on behalf of the Partnership, a right of first opportunity
     arrangement and other conflict avoidance agreements with various Affiliates
     of the Partnership and the General Partner, on such terms as the General
     Partner, in its sole and absolute discretion, believes are advisable.
 
     Section 7.7  Indemnification.
 
          A. To the fullest extent permitted by applicable law, the Partnership
     shall indemnify each Indemnitee from and against any and all losses,
     claims, damages, liabilities, joint or several, expenses (including,
     without limitation, attorney's fees and other legal fees and expenses),
     judgments, fines, settlements and other amounts arising from any and all
     claims, demands, actions, suits or proceedings, civil, criminal,
     administrative or investigative, that relate to the operations of the
     Partnership ("Actions")
 
                                      B-30
<PAGE>   241
 
     as set forth in this Agreement in which such Indemnitee may be involved, or
     is threatened to be involved, as a party or otherwise; provided, however,
     that the Partnership shall not indemnify an Indemnitee (i) for willful
     misconduct or a knowing violation of the law or (ii) for any transaction
     for which such Indemnitee received an improper personal benefit in
     violation or breach of any provision of this Agreement. Without limitation,
     the foregoing indemnity shall extend to any liability of any Indemnitee,
     pursuant to a loan guaranty or otherwise, for any indebtedness of the
     Partnership or any Subsidiary of the Partnership (including, without
     limitation, any indebtedness which the Partnership or any Subsidiary of the
     Partnership has assumed or taken subject to), and the General Partner is
     hereby authorized and empowered, on behalf of the Partnership, to enter
     into one or more indemnity agreements consistent with the provisions of
     this Section 7.7 in favor of any Indemnitee having or potentially having
     liability for any such indebtedness. It is the intention of this Section
     7.7.A that the Partnership indemnify each Indemnitee to the fullest extent
     permitted by law. The termination of any proceeding by judgment, order or
     settlement does not create a presumption that the Indemnitee did not meet
     the requisite standard of conduct set forth in this Section 7.7.A. The
     termination of any proceeding by conviction of an Indemnitee or upon a plea
     of nolo contendere or its equivalent by an Indemnitee, or an entry of an
     order of probation against an Indemnitee prior to judgment, does not create
     a presumption that such Indemnitee acted in a manner contrary to that
     specified in this Section 7.7.A with respect to the subject matter of such
     proceeding. Any indemnification pursuant to this Section 7.7 shall be made
     only out of the assets of the Partnership, and neither the General Partner
     nor any Limited Partner shall have any obligation to contribute to the
     capital of the Partnership or otherwise provide funds to enable the
     Partnership to fund its obligations under this Section 7.7.
 
          B. To the fullest extent permitted by law, expenses incurred by an
     Indemnitee who is a party to a proceeding or otherwise subject to or the
     focus of or is involved in any Action shall be paid or reimbursed by the
     Partnership as incurred by the Indemnitee in advance of the final
     disposition of the Action upon receipt by the Partnership of (i) a written
     affirmation by the Indemnitee of the Indemnitee's good faith belief that
     the standard of conduct necessary for indemnification by the Partnership as
     authorized in this Section 7.7.A has been met, and (ii) a written
     undertaking by or on behalf of the Indemnitee to repay the amount if it
     shall ultimately be determined that the standard of conduct has not been
     met.
 
          C. The indemnification provided by this Section 7.7 shall be in
     addition to any other rights to which an Indemnitee or any other Person may
     be entitled under any agreement, pursuant to any vote of the Partners, as a
     matter of law or otherwise, and shall continue as to an Indemnitee who has
     ceased to serve in such capacity and shall inure to the benefit of the
     heirs, successors, assigns and administrators of the Indemnitee unless
     otherwise provided in a written agreement with such Indemnitee or in the
     writing pursuant to which such Indemnitee is indemnified.
 
          D. The Partnership may, but shall not be obligated to, purchase and
     maintain insurance, on behalf of any of the Indemnitees and such other
     Persons as the General Partner shall determine, against any liability that
     may be asserted against or expenses that may be incurred by such Person in
     connection with the Partnership's activities, regardless of whether the
     Partnership would have the power to indemnify such Person against such
     liability under the provisions of this Agreement.
 
          E. Any liabilities which an Indemnitee incurs as a result of acting on
     behalf of the Partnership or the General Partner (whether as a fiduciary or
     otherwise) in connection with the operation, administration or maintenance
     of an employee benefit plan or any related trust or funding mechanism
     (whether such liabilities are in the form of excise taxes assessed by the
     IRS, penalties assessed by the Department of Labor, restitutions to such a
     plan or trust or other funding mechanism or to a participant or beneficiary
     of such plan, trust or other funding mechanism, or otherwise) shall be
     treated as liabilities or judgments or fines under this Section 7.7, unless
     such liabilities arise as a result of (i) such Indemnitee's intentional
     misconduct or knowing violation of the law, or (ii) any transaction in
     which such Indemnitee received a personal benefit in violation or breach of
     any provision of this Agreement or applicable law.
 
          F. In no event may an Indemnitee subject any of the Partners to
     personal liability by reason of the indemnification provisions set forth in
     this Agreement.
 
                                      B-31
<PAGE>   242
 
          G. An Indemnitee shall not be denied indemnification in whole or in
     part under this Section 7.7 because the Indemnitee had an interest in the
     transaction with respect to which the indemnification applies if the
     transaction was otherwise permitted by the terms of this Agreement.
 
          H. The provisions of this Section 7.7 are for the benefit of the
     Indemnitees, their heirs, successors, assigns and administrators and shall
     not be deemed to create any rights for the benefit of any other Persons.
     Any amendment, modification or repeal of this Section 7.7 or any provision
     hereof shall be prospective only and shall not in any way affect the
     limitations on the Partnership's liability to any Indemnitee under this
     Section 7.7 as in effect immediately prior to such amendment, modification
     or repeal with respect to claims arising from or relating to matters
     occurring, in whole or in part, prior to such amendment, modification or
     repeal, regardless of when such claims may arise or be asserted.
 
          I. It is the intent of the Partners that any amounts paid by the
     Partnership to the General Partner pursuant to this Section 7.7 shall be
     treated as "guaranteed payments" within the meaning of Code Section 707(c).
 
     Section 7.8  Liability of the General Partner.
 
          A. Notwithstanding anything to the contrary set forth in this
     Agreement, neither the General Partner nor any of its directors or officers
     shall be liable or accountable in damages or otherwise to the Partnership,
     any Partners or any Assignees for losses sustained, liabilities incurred or
     benefits not derived as a result of errors in judgment or mistakes of fact
     or law or of any act or omission if the General Partner or such director or
     officer acted in good faith.
 
          B. The Limited Partners expressly acknowledge that the General Partner
     is acting for the benefit of the Partnership, the Limited Partners and the
     General Partner's shareholders collectively and that the General Partner is
     under no obligation to give priority to the separate interests of the
     Limited Partners or the General Partner's shareholders (including, without
     limitation, the tax consequences to Limited Partners, Assignees or the
     General Partner's shareholders) in deciding whether to cause the
     Partnership to take (or decline to take) any actions.
 
          C. Subject to its obligations and duties as General Partner set forth
     in Section 7.1.A hereof, the General Partner may exercise any of the powers
     granted to it by this Agreement and perform any of the duties imposed upon
     it hereunder either directly or by or through its employees or agents
     (subject to the supervision and control of the General Partner). The
     General Partner shall not be responsible for any misconduct or negligence
     on the part of any such agent appointed by it in good faith.
 
          D. Any amendment, modification or repeal of this Section 7.8 or any
     provision hereof shall be prospective only and shall not in any way affect
     the limitations on the General Partner's, and its officers' and directors',
     liability to the Partnership and the Limited Partners under this Section
     7.8 as in effect immediately prior to such amendment, modification or
     repeal with respect to claims arising from or relating to matters
     occurring, in whole or in part, prior to such amendment, modification or
     repeal, regardless of when such claims may arise or be asserted.
 
          E. Notwithstanding anything herein to the contrary, except for fraud,
     willful misconduct or gross negligence, or pursuant to any express
     indemnities given to the Partnership by any Partner pursuant to any other
     written instrument, no Partner shall have any personal liability
     whatsoever, to the Partnership or to the other Partner(s), for the debts or
     liabilities of the Partnership or the Partnership's obligations hereunder,
     and the full recourse of the other Partner(s) shall be limited to the
     interest of that Partner in the Partnership. To the fullest extent
     permitted by law, no officer, director or shareholder of the General
     Partner shall be liable to the Partnership for money damages except for (i)
     active and deliberate dishonesty established by a non-appealable final
     judgment or (ii) actual receipt of an improper benefit or profit in money,
     property or services. Without limitation of the foregoing, and except for
     fraud, willful misconduct or gross negligence, or pursuant to any such
     express indemnity, no property or assets of any Partner, other than its
     interest in the Partnership, shall be subject to levy, execution or other
     enforcement procedures for the satisfaction of any judgment (or other
     judicial process) in favor of any other
 
                                      B-32
<PAGE>   243
 
     Partner(s) and arising out of, or in connection with, this Agreement. This
     Agreement is executed by the officers of the General Partner solely as
     officers of the same and not in their own individual capacities.
 
          F. To the extent that, at law or in equity, the General Partner has
     duties (including fiduciary duties) and liabilities relating thereto to the
     Partnership or the Limited Partners, the General Partner shall not be
     liable to the Partnership or to any other Partner for its good faith
     reliance on the provisions of this Agreement. The provisions of this
     Agreement, to the extent that they restrict the duties and liabilities of
     the General Partner otherwise existing at law or in equity, are agreed by
     the Partners to replace such other duties and liabilities of such General
     Partner.
 
     Section 7.9  Other Matters Concerning the General Partner.
 
          A. The General Partner may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, bond,
     debenture or other paper or document believed by it in good faith to be
     genuine and to have been signed or presented by the proper party or
     parties.
 
          B. The General Partner may consult with legal counsel, accountants,
     appraisers, management consultants, investment bankers, architects,
     engineers, environmental consultants and other consultants and advisers
     selected by it, and any act taken or omitted to be taken in reliance upon
     the opinion of such Persons as to matters that the General Partner
     reasonably believes to be within such Person's professional or expert
     competence shall be conclusively presumed to have been done or omitted in
     good faith and in accordance with such opinion.
 
          C. The General Partner shall have the right, in respect of any of its
     powers or obligations hereunder, to act through any of its duly authorized
     officers and a duly appointed attorney or attorneys-in-fact. Each such
     attorney shall, to the extent provided by the General Partner in the power
     of attorney, have full power and authority to do and perform all and every
     act and duty that is permitted or required to be done by the General
     Partner hereunder.
 
          D. Notwithstanding any other provision of this Agreement or the Act,
     any action of the General Partner on behalf of the Partnership or any
     decision of the General Partner to refrain from acting on behalf of the
     Partnership, undertaken in the good faith belief that such action or
     omission is necessary or advisable in order (i) to protect the ability of
     the Previous General Partner to continue to qualify as a REIT, (ii) for the
     Previous General Partner otherwise to satisfy the REIT Requirements, (iii)
     to avoid the Previous General Partner incurring any taxes under Code
     Section 857 or Code Section 4981 or (iv) for the General Partner or the
     Special Limited Partner to continue to qualify as a "qualified REIT
     subsidiary" (within the meaning of Code Section 856(i)(2)), is expressly
     authorized under this Agreement and is deemed approved by all of the
     Limited Partners.
 
     Section 7.10  Title to Partnership Assets. Title to Partnership assets,
whether real, personal or mixed and whether tangible or intangible, shall be
deemed to be owned by the Partnership as an entity, and no Partner, individually
or collectively with other Partners or Persons, shall have any ownership
interest in such Partnership assets or any portion thereof. Title to any or all
of the Partnership assets may be held in the name of the Partnership, the
General Partner or one or more nominees, as the General Partner may determine,
including Affiliates of the General Partner. The General Partner hereby declares
and warrants that any Partnership assets for which legal title is held in the
name of the General Partner or any nominee or Affiliate of the General Partner
shall be held by the General Partner for the use and benefit of the Partnership
in accordance with the provisions of this Agreement; provided, however, that the
General Partner shall use its best efforts to cause beneficial and record title
to such assets to be vested in the Partnership as soon as reasonably
practicable. All Partnership assets shall be recorded as the property of the
Partnership in its books and records, irrespective of the name in which legal
title to such Partnership assets is held.
 
     Section 7.11  Reliance by Third Parties. Notwithstanding anything to the
contrary in this Agreement, any Person dealing with the Partnership shall be
entitled to assume that the General Partner has full power and authority,
without the consent or approval of any other Partner or Person, to encumber,
sell or otherwise
                                      B-33

use in any manner any and all assets of the Partnership and to enter into any
contracts on behalf of the Partnership, and take any and all actions on behalf
of the Partnership, and such Person shall be entitled to deal with the General
Partner as if it were the Partnership's sole party in interest, both legally and
beneficially. Each Limited Partner hereby waives any and all defenses or other
remedies that may be available against such Person to contest, negate or
disaffirm any action of the General Partner in connection with any such dealing.
In no event shall any Person dealing with the General Partner or its
representatives be obligated to ascertain that the terms of this Agreement have
been complied with or to inquire into the necessity or expediency of any act or
action of the General Partner or its representatives. Each and every
certificate, document or other instrument executed on behalf of the Partnership
by the General Partner or its representatives shall be conclusive evidence in
favor of any and every Person relying thereon or claiming thereunder that (i) at
the time of the execution and delivery of such certificate, document or
instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Partnership.

                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS
 
     Section 8.1  Limitation of Liability. The Limited Partners shall have no
liability under this Agreement except as expressly provided in this Agreement
(including, without limitation, Section 10.4 hereof) or under the Act.
 
     Section 8.2  Management of Business. No Limited Partner or Assignee (other
than the General Partner, any of its Affiliates or any officer, director,
member, employee, partner, agent or trustee of the General Partner, the
Partnership or any of their Affiliates, in their capacity as such) shall take
part in the operations, management or control (within the meaning of the Act) of
the Partnership's business, transact any business in the Partnership's name or
have the power to sign documents for or otherwise bind the Partnership. The
transaction of any such business by the General Partner, any of its Affiliates
or any officer, director, member, employee, partner, agent, representative, or
trustee of the General Partner, the Partnership or any of their Affiliates, in
their capacity as such, shall not affect, impair or eliminate the limitations on
the liability of the Limited Partners or Assignees under this Agreement.
 
     Section 8.3  Outside Activities of Limited Partners. Subject to any
agreements entered into pursuant to Section 7.6.D hereof and any other
agreements entered into by a Limited Partner or its Affiliates with the General
Partner, the Partnership or a Subsidiary (including, without limitation, any
employment agreement), any Limited Partner and any Assignee, officer, director,
employee, agent, trustee, Affiliate or shareholder of any Limited Partner shall
be entitled to and may have business interests and engage in business activities
in addition to those relating to the Partnership, including business interests
and activities that are in direct or indirect competition with the Partnership
or that are enhanced by the activities of the Partnership. Neither the
Partnership nor any Partners shall have any rights by virtue of this Agreement
in any business ventures of any Limited Partner or Assignee. Subject to such
agreements, none of the Limited Partners nor any other Person shall have any
rights by virtue of this Agreement or the partnership relationship established
hereby in any business ventures of any other Person (other than the General
Partner, to the extent expressly provided herein), and such Person shall have no
obligation pursuant to this Agreement, subject to Section 7.6.D hereof and any
other agreements entered into by a Limited Partner or its Affiliates with the
General Partner, the Partnership or a Subsidiary, to offer any interest in any
such business ventures to the Partnership, any Limited Partner or any such other
Person, even if such opportunity is of a character that, if presented to the
Partnership, any Limited Partner or such other Person, could be taken by such
Person.
 
     Section 8.4  Return of Capital. Except pursuant to the rights of Redemption
set forth in Section 8.6 hereof, no Limited Partner shall be entitled to the
withdrawal or return of its Capital Contribution, except to the extent of
distributions made pursuant to this Agreement or upon termination of the
Partnership as provided herein. Except to the extent provided in Article 6
hereof or otherwise expressly provided in this

                                      B-34
<PAGE>   245
 
Agreement, no Limited Partner or Assignee shall have priority over any other
Limited Partner or Assignee either as to the return of Capital Contributions or
as to profits, losses or distributions.
 
     Section 8.5  Rights of Limited Partners Relating to the Partnership.
 
          A. In addition to other rights provided by this Agreement or by the
     Act, and except as limited by Section 8.5.C hereof, each Limited Partner
     shall have the right, for a purpose reasonably related to such Limited
     Partner's interest as a limited partner in the Partnership, upon written
     demand with a statement of the purpose of such demand and at such Limited
     Partner's own expense:
 
             (1) to obtain a copy of (i) the most recent annual and quarterly
        reports filed with the SEC by the Previous General Partner or the
        General Partner pursuant to the Exchange Act and (ii) each report or
        other written communication sent to the shareholders of the Previous
        General Partner;
 
             (2) to obtain a copy of the Partnership's federal, state and local
        income tax returns for each Fiscal Year;
 
             (3) to obtain a current list of the name and last known business,
        residence or mailing address of each Partner;
 
             (4) to obtain a copy of this Agreement and the Certificate and all
        amendments thereto, together with executed copies of all powers of
        attorney pursuant to which this Agreement, the Certificate and all
        amendments thereto have been executed; and
 
             (5) to obtain true and full information regarding the amount of
        cash and a description and statement of any other property or services
        contributed by each Partner and that each Partner has agreed to
        contribute in the future, and the date on which each became a Partner.
 
          B. The Partnership shall notify any Limited Partner that is a
     Qualifying Party, on request, of the then current Adjustment Factor or any
     change made to the Adjustment Factor.
 
          C. Notwithstanding any other provision of this Section 8.5, the
     General Partner may keep confidential from the Limited Partners, for such
     period of time as the General Partner determines in its sole and absolute
     discretion to be reasonable, any information that (i) the General Partner
     believes to be in the nature of trade secrets or other information the
     disclosure of which the General Partner in good faith believes is not in
     the best interests of the Partnership or the General Partner or (ii) the
     Partnership or the General Partner is required by law or by agreements with
     unaffiliated third parties to keep confidential.
 
     Section 8.6  Redemption Rights of Qualifying Parties.
 
          A. After the first Twelve-Month Period, a Qualifying Party, but no
     other Limited Partner or Assignee, shall have the right (subject to the
     terms and conditions set forth herein) to require the Partnership to redeem
     all or a portion of the Redeemable Units held by such Tendering Party (such
     Redeemable Units being hereafter "Tendered Units") in exchange (a
     "Redemption") for the Cash Amount payable on the Specified Redemption Date.
     Any Redemption shall be exercised pursuant to a Notice of Redemption
     delivered to the General Partner by the Qualifying Party when exercising
     the Redemption right (the "Tendering Party"). The Partnership's obligation
     to effect a Redemption, however, shall not arise or be binding against the
     Partnership (i) until and unless there has been a Declination and (ii)
     before the Business Day following the Cut-Off Date. Regardless of the
     binding or non-binding nature of a pending Redemption, a Tendering Party
     shall have no right to receive distributions with respect to any Tendered
     Units (other than the Cash Amount) paid after delivery of the Notice of
     Redemption, whether or not the Partnership Record Date for such
     distribution precedes or coincides with such delivery of the Notice of
     Redemption. In the event of a Redemption, the Cash Amount shall be
     delivered as a certified check payable to the Tendering Party or, in the
     General Partner's sole and absolute discretion, in immediately available
     funds.
 
                                      B-35
<PAGE>   246
 
          B. Notwithstanding the provisions of Section 8.6.A hereof, on or
     before the close of business on the Cut-Off Date, the General Partner may,
     in its sole and absolute discretion but subject to the Ownership Limit and
     the transfer restrictions and other limitations of the Charter, elect to
     cause the Previous General Partner to acquire some or all (such percentage
     being referred to as the "Applicable Percentage") of the Tendered Units
     from the Tendering Party in exchange for REIT Shares. In making such
     election to cause the Previous General Partner to acquire Tendered Units,
     the General Partner shall act in a fair, equitable and reasonable manner
     that neither prefers one group or class of Qualifying Parties over another
     nor discriminates against a group or class of Qualifying Parties. If the
     General Partner so elects, on the Specified Redemption Date the Tendering
     Party shall sell such number of the Tendered Units to the Previous General
     Partner in exchange for a number of REIT Shares equal to the product of the
     REIT Shares Amount and the Applicable Percentage. The Tendering Party shall
     submit (i) such information, certification or affidavit as the Previous
     General Partner may reasonably require in connection with the application
     of the Ownership Limit and other restrictions and limitations of the
     Charter to any such acquisition and (ii) such written representations,
     investment letters, legal opinions or other instruments necessary, in the
     Previous General Partner's view, to effect compliance with the Securities
     Act. In the event of a purchase of the Tendered Units by the Previous
     General Partner pursuant to this Section 8.6.B, the Tendering Party shall
     no longer have the right to cause the Partnership to effect a Redemption of
     such Tendered Units, and, upon notice to the Tendering Party by the General
     Partner or the Previous General Partner, given on or before the close of
     business on the Cut-Off Date, that the Previous General Partner has elected
     to acquire some or all of the Tendered Units pursuant to this Section
     8.6.B, the obligation of the Partnership to effect a Redemption of the
     Tendered Units as to which the General Partner's notice relates shall not
     accrue or arise. The product of the Applicable Percentage and the REIT
     Shares Amount, if applicable, shall be delivered by the Previous General
     Partner as duly authorized, validly issued, fully paid and accessible REIT
     Shares and, if applicable, Rights, free of any pledge, lien, encumbrance or
     restriction, other than the Ownership Limit and other restrictions provided
     in the Charter, the Bylaws of the Previous General Partner, the Securities
     Act and relevant state securities or "blue sky" laws. Neither any Tendering
     Party whose Tendered Units are acquired by the Previous General Partner
     pursuant to this Section 8.6.B, any Partner, any Assignee nor any other
     interested Person shall have any right to require or cause the Previous
     General Partner or the General Partner to register, qualify or list any
     REIT Shares owned or held by such Person, whether or not such REIT Shares
     are issued pursuant to this Section 8.6.B, with the SEC, with any state
     securities commissioner, department or agency, under the Securities Act or
     the Exchange Act or with any stock exchange; provided, however, that this
     limitation shall not be in derogation of any registration or similar rights
     granted pursuant to any other written agreement between the Previous
     General Partner and any such Person. Notwithstanding any delay in such
     delivery, the Tendering Party shall be deemed the owner of such REIT Shares
     and Rights for all purposes, including, without limitation, rights to vote
     or consent, receive dividends, and exercise rights, as of the Specified
     Redemption Date. REIT Shares issued upon an acquisition of the Tendered
     Units by the Previous General Partner pursuant to this Section 8.6.B may
     contain such legends regarding restrictions under the Securities Act and
     applicable state securities laws as the Previous General Partner in good
     faith determines to be necessary or advisable in order to ensure compliance
     with such laws.
 
          C. Notwithstanding the provisions of Section 8.6.A and 8.6.B hereof,
     the Tendering Parties (i) where the Redemption would consist of less than
     all the Partnership Common Units held by Partners other than the General
     Partner and the Special Limited Partner, shall not be entitled to elect or
     effect a Redemption to the extent that the aggregate Percentage Interests
     of the Limited Partners (other than the Special Limited Partner) would be
     reduced, as a result of the Redemption (or the acquisition of the Tendered
     Units by the Previous General Partner pursuant to Section 8.6.B hereof), to
     less than one percent (1%) and (ii) shall have no rights under this
     Agreement that would otherwise be prohibited under the Charter. To the
     extent that any attempted Redemption or acquisition of the Tendered Units
     by the Previous General Partner pursuant to Section 8.6.B hereof would be
     in violation of this Section 8.6.C, it shall be null and void ab initio,
     and the Tendering Party shall not acquire any rights or economic interests
     in REIT Shares otherwise issuable by the Previous General Partner under
     Section 8.6.B hereof.
 
                                      B-36
<PAGE>   247
 
          D. In the event that the Previous General Partner declines or fails to
     exercise its purchase rights pursuant to Section 8.6.B hereof following
     receipt of a Notice of Redemption (a "Declination"):
 
             (1) The Previous General Partner or the General Partner shall give
        notice of such Declination to the Tendering Party on or before the close
        of business on the Cut-Off Date. The failure of both the Previous
        General Partner and the General Partner to give notice of such
        Declination by the close of business on the Cut-Off Date shall itself
        constitute a Declination.
 
             (2) The Partnership may elect to raise funds for the payment of the
        Cash Amount either (a) by requiring that the General Partner contribute
        such funds from the proceeds of a registered public offering (a "Public
        Offering Funding") by the Previous General Partner of a number of REIT
        Shares ("Registrable Shares") equal to the REIT Shares Amount with
        respect to the Tendered Units or (b) from any other sources (including,
        but not limited to, the sale of any Property and the incurrence of
        additional Debt) available to the Partnership.
 
             (3) Promptly upon the General Partner's receipt of the Notice of
        Redemption and the Previous General Partner or the General Partner
        giving notice of the Previous General Partner's Declination, the General
        Partner shall give notice (a "Single Funding Notice") to all Qualifying
        Parties then holding a Partnership Interest (or an interest therein) and
        having Redemption rights pursuant to this Section 8.6 and require that
        all such Qualifying Parties elect whether or not to effect a Redemption
        of their Partnership Common Units to be funded through such Public
        Offering Funding. In the event that any such Qualifying Party elects to
        effect such a Redemption, it shall give notice thereof and of the number
        of Partnership Common Units to be made subject thereon in writing to the
        General Partner within ten (10) Business Days after receipt of the
        Single Funding Notice, and such Qualifying Party shall be treated as a
        Tendering Party for all purposes of this Section 8.6. In the event that
        a Qualifying Party does not so elect, it shall be deemed to have waived
        its right to effect a Redemption for the current Twelve-Month Period;
        provided, however, that the Previous General Partner shall not be
        required to acquire Partnership Common Units pursuant to this Section
        8.6.D more than twice within a Twelve-Month Period.
 
     Any proceeds from a Public Offering Funding that are in excess of the Cash
     Amount shall be for the sole benefit of the Previous General Partner and/or
     the General Partner. The General Partner and/or the Special Limited Partner
     shall make a Capital Contribution of such amounts to the Partnership for an
     additional General Partner Interest and/or Limited Partner Interest. Any
     such contribution shall entitle the General Partner and the Special Limited
     Partner, as the case may be, to an equitable Percentage Interest
     adjustment.
 
          E. Notwithstanding the provisions of Section 8.6.B hereof, the
     Previous General Partner shall not, under any circumstances, elect to
     acquire Tendered Units in exchange for the REIT Shares Amount if such
     exchange would be prohibited under the Charter.
 
          F. Notwithstanding anything herein to the contrary (but subject to
     Section 8.6.C hereof), with respect to any Redemption (or any tender of
     Redeemable Units for Redemption if the Tendered Units are acquired by the
     Previous General Partner pursuant to Section 8.6.B hereof) pursuant to this
     Section 8.6:
 
             (1) All Partnership Common Units acquired by the Previous General
        Partner pursuant to Section 8.6.B hereof shall be contributed by the
        Previous General Partner to either or both of the General Partner and
        the Special Limited Partner in such proportions as the Previous General
        Partner, the General Partner and the Special Limited Partner shall
        determine. Any Partnership Common Units so contributed to the General
        Partner shall automatically, and without further action required, be
        converted into and deemed to be a General Partner Interest comprised of
        the same number of Partnership Common Units. Any Partnership Common
        Units so contributed to the Special Limited Partner shall remain
        outstanding.
 
             (2) Subject to the Ownership Limit, no Tendering Party may effect a
        Redemption for less than five hundred (500) Redeemable Units or, if such
        Tendering Party holds (as a Limited Partner or,

                                      B-37
<PAGE>   248
 
        economically, as an Assignee) less than five hundred (500) Redeemable
        Units, all of the Redeemable Units held by such Tendering Party.
 
             (3) Each Tendering Party (a) may effect a Redemption only once in
        each fiscal quarter of a Twelve-Month Period and (b) may not effect a
        Redemption during the period after the Partnership Record Date with
        respect to a distribution and before the record date established by the
        Previous General Partner for a distribution to its shareholders of some
        or all of its portion of such Partnership distribution.
 
             (4) Notwithstanding anything herein to the contrary, with respect
        to any Redemption or acquisition of Tendered Units by the Previous
        General Partner pursuant to Section 8.6.B hereof, in the event that the
        Previous General Partner or the General Partner gives notice to all
        Limited Partners (but excluding any Assignees) then owning Partnership
        Interests (a "Primary Offering Notice") that the Previous General
        Partner desires to effect a primary offering of its equity securities
        then, unless the Previous General Partner and the General Partner
        otherwise consent, commencement of the actions denoted in Section 8.6.E
        hereof as to a Public Offering Funding with respect to any Notice of
        Redemption thereafter received, whether or not the Tendering Party is a
        Limited Partner, may be delayed until the earlier of (a) the completion
        of the primary offering or (b) ninety (90) days following the giving of
        the Primary Offering Notice.
 
             (5) Without the Consent of the Previous General Partner, no
        Tendering Party may effect a Redemption within ninety (90) days
        following the closing of any prior Public Offering Funding.
 
             (6) The consummation of such Redemption (or an acquisition of
        Tendered Units by the Previous General Partner pursuant to Section 8.6.B
        hereof, as the case may be) shall be subject to the expiration or
        termination of the applicable waiting period, if any, under the
        Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.
 
             (7) The Tendering Party shall continue to own (subject, in the case
        of an Assignee, to the provision of Section 11.5 hereof) all Redeemable
        Units subject to any Redemption, and be treated as a Limited Partner or
        an Assignee, as applicable, with respect to such Redeemable Units for
        all purposes of this Agreement, until such Redeemable Units are either
        paid for by the Partnership pursuant to Section 8.6.A hereof or
        transferred to the Previous General Partner (or directly to the General
        Partner or Special Limited Partner) and paid for, by the issuance of the
        REIT Shares, pursuant to Section 8.6.B hereof on the Specified
        Redemption Date. Until a Specified Redemption Date and an acquisition of
        the Tendered Units by the Previous General Partner pursuant to Section
        8.6.B hereof, the Tendering Party shall have no rights as a shareholder
        of the Previous General Partner with respect to the REIT Shares issuable
        in connection with such acquisition.
 
     For purposes of determining compliance with the restrictions set forth in
     this Section 8.6.F, all Partnership Common Units beneficially owned by a
     Related Party of a Tendering Party shall be considered to be owned or held
     by such Tendering Party.
 
          G. In connection with an exercise of Redemption rights pursuant to
     this Section 8.6, the Tendering Party shall submit the following to the
     General Partner, in addition to the Notice of Redemption:
 
             (1) A written affidavit, dated the same date as the Notice of
        Redemption, (a) disclosing the actual and constructive ownership, as
        determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT
        Shares by (i) such Tendering Party and (ii) any Related Party and (b)
        representing that, after giving effect to the Redemption or an
        acquisition of the Tendered Units by the Previous General Partner
        pursuant to Section 8.6.B hereof, neither the Tendering Party nor any
        Related Party will own REIT Shares in excess of the Ownership Limit;
 
             (2) A written representation that neither the Tendering Party nor
        any Related Party has any intention to acquire any additional REIT
        Shares prior to the closing of the Redemption or an acquisition of the
        Tendered Units by the Previous General Partner pursuant to Section 8.6.B
        hereof on the Specified Redemption Date; and

                                      B-38
<PAGE>   249
 
             (3) An undertaking to certify, at and as a condition to the closing
        of (i) the Redemption or (ii) the acquisition of the Tendered Units by
        the Previous General Partner pursuant to Section 8.6.B hereof on the
        Specified Redemption Date, that either (a) the actual and constructive
        ownership of REIT Shares by the Tendering Party and any Related Party
        remain unchanged from that disclosed in the affidavit required by
        Section 8.6.G(1) or (b) after giving effect to the Redemption or an
        acquisition of the Tendered Units by the Previous General Partner
        pursuant to Section 8.6.B hereof, neither the Tendering Party nor any
        Related Party shall own REIT Shares in violation of the Ownership Limit.
 
     Section 8.7  Partnership Right to Call Limited Partner
Interests. Notwithstanding any other provision of this Agreement, on and after
the date on which the aggregate Percentage Interests of the Limited Partners
(other than the Special Limited Partner) are less than one percent (1%), the
Partnership shall have the right, but not the obligation, from time to time and
at any time to redeem any and all outstanding Limited Partner Interests (other
than the Special Limited Partner's Limited Partner Interest) by treating any
Limited Partner as a Tendering Party who has delivered a Notice of Redemption
pursuant to Section 8.6 hereof for the amount of Partnership Common Units to be
specified by the General Partner, in its sole and absolute discretion, by notice
to such Limited Partner that the Partnership has elected to exercise its rights
under this Section 8.7. Such notice given by the General Partner to a Limited
Partner pursuant to this Section 8.7 shall be treated as if it were a Notice of
Redemption delivered to the General Partner by such Limited Partner. For
purposes of this Section 8.7, (a) any Limited Partner (whether or not otherwise
a Qualifying Party) may, in the General Partner's sole and absolute discretion,
be treated as a Qualifying Party that is a Tendering Party and (b) the
provisions of Sections 8.6.C(1), 8.6.F(2), 8.6.F(3) and 8.6.F(5) hereof shall
not apply, but the remainder of Section 8.6 hereof shall apply, mutatis
mutandis.

                     BOOKS, RECORDS, ACCOUNTING AND REPORTS
 
     Section 9.1  Records and Accounting.
 
          A. The General Partner shall keep or cause to be kept at the principal
     office of the Partnership those records and documents required to be
     maintained by the Act and other books and records deemed by the General
     Partner to be appropriate with respect to the Partnership's business,
     including, without limitation, all books and records necessary to provide
     to the Limited Partners any information, lists and copies of documents
     required to be provided pursuant to Section 8.5.A or Section 9.3 hereof.
     Any records maintained by or on behalf of the Partnership in the regular
     course of its business may be kept on, or be in the form for, punch cards,
     magnetic tape, photographs, micrographics or any other information storage
     device, provided that the records so maintained are convertible into
     clearly legible written form within a reasonable period of time.
 
          B. The books of the Partnership shall be maintained, for financial and
     tax reporting purposes, on an accrual basis in accordance with generally
     accepted accounting principles, or on such other basis as the General
     Partner determines to be necessary or appropriate. To the extent permitted
     by sound accounting practices and principles, the Partnership, the General
     Partner and the Previous General Partner may operate with integrated or
     consolidated accounting records, operations and principles.
 
     Section 9.2  Fiscal Year. The Fiscal Year of the Partnership shall be the
calendar year.
 
     Section 9.3  Reports.
 
          A. As soon as practicable, but in no event later than one hundred five
     (105) days after the close of each Fiscal Year, the General Partner shall
     cause to be mailed to each Limited Partner, of record as of the close of
     the Fiscal Year, an annual report containing financial statements of the
     Partnership, or of the Previous General Partner if such statements are
     prepared solely on a consolidated basis with the Previous General Partner,
     for such Fiscal Year, presented in accordance with generally accepted
     accounting
 
                                      B-39

     principles, such statements to be audited by a nationally recognized firm
     of independent public accountants selected by the General Partner.
 
          B. As soon as practicable, but in no event later than one hundred five
     (105) days after the close of each calendar quarter (except the last
     calendar quarter of each year), the General Partner shall cause to be
     mailed to each Limited Partner, of record as of the last day of the
     calendar quarter, a report containing unaudited financial statements of the
     Partnership, or of the Previous General Partner if such statements are
     prepared solely on a consolidated basis with the Previous General Partner,
     and such other information as may be required by applicable law or
     regulation or as the General Partner determines to be appropriate. At the
     request of any Limited Partner, the General Partner shall provide access to
     the books, records and workpapers upon which the reports required by this
     Section 9.3 are based, to the extent required by the Act.
 
                                   ARTICLE 10
 
                                  TAX MATTERS
 
     Section 10.1  Preparation of Tax Returns. The General Partner shall arrange
for the preparation and timely filing of all returns with respect to Partnership
income, gains, deductions, losses and other items required of the Partnership
for federal and state income tax purposes and shall use all reasonable effort to
furnish, within ninety (90) days of the close of each taxable year, the tax
information reasonably required by Limited Partners for federal and state income
tax reporting purposes. The Limited Partners shall promptly provide the General
Partner with such information relating to the Contributed Properties, including
tax basis and other relevant information, as may be reasonably requested by the
General Partner from time to time.
 
     Section 10.2  Tax Elections. Except as otherwise provided herein, the
General Partner shall, in its sole and absolute discretion, determine whether to
make any available election pursuant to the Code, including, but not limited to,
the election under Code Section 754 and the election to use the "recurring item"
method of accounting provided under Code Section 461(h) with respect to property
taxes imposed on the Partnership's Properties; provided, however, that, if the
"recurring item" method of accounting is elected with respect to such property
taxes, the Partnership shall pay the applicable property taxes prior to the date
provided in Code Section 461(h) for purposes of determining economic
performance. The General Partner shall have the right to seek to revoke any such
election (including, without limitation, any election under Code Sections 461(h)
and 754) upon the General Partner's determination in its sole and absolute
discretion that such revocation is in the best interests of the Partners.
 
     Section 10.3  Tax Matters Partner.
 
          A. The General Partner shall be the "tax matters partner" of the
     Partnership for federal income tax purposes. The tax matters partner shall
     receive no compensation for its services. All third-party costs and
     expenses incurred by the tax matters partner in performing its duties as
     such (including legal and accounting fees and expenses) shall be borne by
     the Partnership in addition to any reimbursement pursuant to Section 7.4
     hereof. Nothing herein shall be construed to restrict the Partnership from
     engaging an accounting firm to assist the tax matters partner in
     discharging its duties hereunder, so long as the compensation paid by the
     Partnership for such services is reasonable. At the request of any Limited
     Partner, the General Partner agrees to consult with such Limited Partner
     with respect to the preparation and filing of any returns and with respect
     to any subsequent audit or litigation relating to such returns; provided,
     however, that the filing of such returns shall be in the sole and absolute
     discretion of the General Partner.
 
          B. The tax matters partner is authorized, but not required:
 
             (1) to enter into any settlement with the IRS with respect to any
        administrative or judicial proceedings for the adjustment of Partnership
        items required to be taken into account by a Partner for income tax
        purposes (such administrative proceedings being referred to as a "tax
        audit" and such judicial proceedings being referred to as "judicial
        review"), and in the settlement agreement the tax
 
                                      B-40
<PAGE>   251
 
        matters partner may expressly state that such agreement shall bind all
        Partners, except that such settlement agreement shall not bind any
        Partner (i) who (within the time prescribed pursuant to the Code and
        Regulations) files a statement with the IRS providing that the tax
        matters partner shall not have the authority to enter into a settlement
        agreement on behalf of such Partner or (ii) who is a "notice partner"
        (as defined in Code Section 6231) or a member of a "notice group" (as
        defined in Code Section 6223(b)(2));
 
             (2) in the event that a notice of a final administrative adjustment
        at the Partnership level of any item required to be taken into account
        by a Partner for tax purposes (a "final adjustment") is mailed to the
        tax matters partner, to seek judicial review of such final adjustment,
        including the filing of a petition for readjustment with the United
        States Tax Court or the United States Claims Court, or the filing of a
        complaint for refund with the District Court of the United States for
        the district in which the Partnership's principal place of business is
        located;
 
             (3) to intervene in any action brought by any other Partner for
        judicial review of a final adjustment;
 
             (4) to file a request for an administrative adjustment with the IRS
        at any time and, if any part of such request is not allowed by the IRS,
        to file an appropriate pleading (petition or complaint) for judicial
        review with respect to such request;
 
             (5) to enter into an agreement with the IRS to extend the period
        for assessing any tax that is attributable to any item required to be
        taken into account by a Partner for tax purposes, or an item affected by
        such item; and
 
             (6) to take any other action on behalf of the Partners in
        connection with any tax audit or judicial review proceeding to the
        extent permitted by applicable law or regulations.
 
     The taking of any action and the incurring of any expense by the tax
     matters partner in connection with any such proceeding, except to the
     extent required by law, is a matter in the sole and absolute discretion of
     the tax matters partner and the provisions relating to indemnification of
     the General Partner set forth in Section 7.7 hereof shall be fully
     applicable to the tax matters partner in its capacity as such.
 
     Section 10.4  Withholding. Each Limited Partner hereby authorizes the
Partnership to withhold from or pay on behalf of or with respect to such Limited
Partner any amount of federal, state, local or foreign taxes that the General
Partner determines that the Partnership is required to withhold or pay with
respect to any amount distributable or allocable to such Limited Partner
pursuant to this Agreement, including, without limitation, any taxes required to
be withheld or paid by the Partnership pursuant to Code Section 1441, Code
Section 1442, Code Section 1445 or Code Section 1446. Any amount paid on behalf
of or with respect to a Limited Partner shall constitute a loan by the
Partnership to such Limited Partner, which loan shall be repaid by such Limited
Partner within fifteen (15) days after notice from the General Partner that such
payment must be made unless (i) the Partnership withholds such payment from a
distribution that would otherwise be made to the Limited Partner or (ii) the
General Partner determines, in its sole and absolute discretion, that such
payment may be satisfied out of the Available Funds of the Partnership that
would, but for such payment, be distributed to the Limited Partner. Each Limited
Partner hereby unconditionally and irrevocably grants to the Partnership a
security interest in such Limited Partner's Partnership Interest to secure such
Limited Partner's obligation to pay to the Partnership any amounts required to
be paid pursuant to this Section 10.4. In the event that a Limited Partner fails
to pay any amounts owed to the Partnership pursuant to this Section 10.4 when
due, the General Partner may, in its sole and absolute discretion, elect to make
the payment to the Partnership on behalf of such defaulting Limited Partner, and
in such event shall be deemed to have loaned such amount to such defaulting
Limited Partner and shall succeed to all rights and remedies of the Partnership
as against such defaulting Limited Partner (including, without limitation, the
right to receive distributions). Any amounts payable by a Limited Partner
hereunder shall bear interest at the base rate on corporate loans at large
United States money center commercial banks, as published from time to time in
the Wall Street Journal, plus four (4) percentage points (but not higher than
the maximum lawful rate) from the date such amount is due (i.e., fifteen (15)
days after demand) until such amount is paid in full. Each Limited

                                      B-41
<PAGE>   252
 
Partner shall take such actions as the Partnership or the General Partner shall
request in order to perfect or enforce the security interest created hereunder.

                           TRANSFERS AND WITHDRAWALS
 
     Section 11.1  Transfer.
 
          A. No part of the interest of a Partner shall be subject to the claims
     of any creditor, to any spouse for alimony or support, or to legal process,
     and may not be voluntarily or involuntarily alienated or encumbered except
     as may be specifically provided for in this Agreement.
 
          B. No Partnership Interest shall be Transferred, in whole or in part,
     except in accordance with the terms and conditions set forth in this
     Article 11. Any Transfer or purported Transfer of a Partnership Interest
     not made in accordance with this Article 11 shall be null and void ab
     initio.
 
          C. Notwithstanding the other provisions of this Article 11 (other than
     Section 11.6.D hereof), the Partnership Interests of the General Partner
     and the Special Limited Partner may be Transferred, in whole or in part, at
     any time or from time to time, to or among the Previous General Partner,
     the General Partner, the Special Limited Partner, and any other Person that
     is, at the time of such Transfer, a "qualified REIT subsidiary" (within the
     meaning of Code Section 856(i)(2)) with respect to the Previous General
     Partner. Any transferee of the entire General Partner Interest pursuant to
     this Section 11.1.C shall automatically become, without further action or
     Consent of any Limited Partners, the sole general partner of the
     Partnership, subject to all the rights, privileges, duties and obligations
     under this Agreement and the Act relating to a general partner. Any
     transferee of a Limited Partner Interest pursuant to this Section 11.1.C
     shall automatically become, without further action or Consent of any
     Limited Partners, a Substituted Limited Partner. Upon any Transfer
     permitted by this Section 11.1.C, the transferor Partner shall be relieved
     of all its obligations under this Agreement. The provisions of Section
     11.2.B (other than the last sentence thereof), 11.3, 11.4.A and 11.5 hereof
     shall not apply to any Transfer permitted by this Section 11.1.C.
 
     Section 11.2  Transfer of General Partner's Partnership Interest.
 
          A. The General Partner may not Transfer any of its General Partner
     Interest or withdraw from the Partnership except as provided in Sections
     11.2.B and 11.2.C hereof.
 
          B. The General Partner shall not withdraw from the Partnership and
     shall not Transfer all or any portion of its interest in the Partnership
     (whether by sale, disposition, statutory merger or consolidation,
     liquidation or otherwise) without the Consent of the Limited Partners,
     which Consent may be given or withheld in the sole and absolute discretion
     of the Limited Partners. Upon any Transfer of such a Partnership Interest
     pursuant to the Consent of the Limited Partners and otherwise in accordance
     with the provisions of this Section 11.2.B, the transferee shall become a
     successor General Partner for all purposes herein, and shall be vested with
     the powers and rights of the transferor General Partner, and shall be
     liable for all obligations and responsible for all duties of the General
     Partner, once such transferee has executed such instruments as may be
     necessary to effectuate such admission and to confirm the agreement of such
     transferee to be bound by all the terms and provisions of this Agreement
     with respect to the Partnership Interest so acquired. It is a condition to
     any Transfer otherwise permitted hereunder that the transferee assumes, by
     operation of law or express agreement, all of the obligations of the
     transferor General Partner under this Agreement with respect to such
     Transferred Partnership Interest, and such Transfer shall relieve the
     transferor General Partner of its obligations under this Agreement without
     the Consent of the Limited Partners. In the event that the General Partner
     withdraws from the Partnership, in violation of this Agreement or
     otherwise, or otherwise dissolves or terminates, or upon the bankruptcy of
     the General Partner, a Majority in Interest of the Limited Partners may
     elect to continue the Partnership business by selecting a successor General
     Partner in accordance with the Act.

          C. The General Partner may merge with another entity if immediately
     after such merger substantially all of the assets of the surviving entity,
     other than the General Partner Interest held by the General Partner, are
     contributed to the Partnership as a Capital Contribution in exchange for
     Partnership Units.
 
     Section 11.3  Limited Partners' Rights to Transfer.
 
          A. General. Prior to the end of the first Twelve-Month Period, no
     Limited Partner shall Transfer all or any portion of its Partnership
     Interest to any transferee without the Consent of the General Partner,
     which Consent may be withheld in its sole and absolute discretion;
     provided, however, that any Limited Partner may, at any time, without the
     consent of the General Partner, (i) Transfer all or part of its Partnership
     Interest to any Designated Party, any Family Member, any Controlled Entity
     or any Affiliate, provided that the transferee is, in any such case, a
     Qualified Transferee, or (ii) pledge (a "Pledge") all or any portion of its
     Partnership Interest to a lending institution, that is not an Affiliate of
     such Limited Partner, as collateral or security for a bona fide loan or
     other extension of credit, and Transfer such pledged Partnership Interest
     to such lending institution in connection with the exercise of remedies
     under such loan or extension or credit (any Transfer or Pledge permitted by
     this proviso is hereinafter referred to as a "Permitted Transfer"). After
     such first Twelve-Month Period, each Limited Partner, and each transferee
     of Partnership Units or Assignee pursuant to a Permitted Transfer, shall
     have the right to Transfer all or any portion of its Partnership Interest
     to any Person, subject to the provisions of Section 11.6 hereof and to
     satisfaction of each of the following conditions:
 
             (1) General Partner Right of First Refusal. The transferring
        Partner shall give written notice of the proposed Transfer to the
        General Partner, which notice shall state (i) the identity of the
        proposed transferee and (ii) the amount and type of consideration
        proposed to be received for the Transferred Partnership Units. The
        General Partner shall have ten (10) Business Days upon which to give the
        Transferring Partner notice of its election to acquire the Partnership
        Units on the proposed terms. If it so elects, it shall purchase the
        Partnership Units on such terms within ten (10) Business Days after
        giving notice of such election; provided, however, that in the event
        that the proposed terms involve a purchase for cash, the General Partner
        may at its election deliver in lieu of all or any portion of such cash a
        note payable to the Transferring Partner at a date as soon as reasonably
        practicable, but in no event later than one hundred eighty (180) days
        after such purchase, and bearing interest at an annual rate equal to the
        total dividends declared with respect to one (1) REIT Share for the four
        (4) preceding fiscal quarters of the General Partner, divided by the
        Value as of the closing of such purchase; provided, further, that such
        closing may be deferred to the extent necessary to effect compliance
        with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if
        applicable, and any other applicable requirements of law. If it does not
        so elect, the Transferring Partner may Transfer such Partnership Units
        to a third party, on terms no more favorable to the transferee than the
        proposed terms, subject to the other conditions of this Section 11.3.
 
             (2) Qualified Transferee. Any Transfer of a Partnership Interest
        shall be made only to a single Qualified Transferee; provided, however,
        that, for such purposes, all Qualified Transferees that are Affiliates,
        or that comprise investment accounts or funds managed by a single
        Qualified Transferee and its Affiliates, shall be considered together to
        be a single Qualified Transferee; provided, further, that each Transfer
        meeting the minimum Transfer restriction of Section 11.3.A(3) hereof may
        be to a separate Qualified Transferee.
 
             (3) Minimum Transfer Restriction. Any Transferring Partner must
        Transfer not less than the lesser of (i) the greater of five hundred
        (500) Partnership Units or one-third ( 1/3) of the number of Partnership
        Units owned by such Partner as of the Effective Date or (ii) all of the
        remaining Partnership Units owned by such Transferring Partner;
        provided, however, that, for purposes of determining compliance with the
        foregoing restriction, all Partnership Units owned by Affiliates of a
        Limited Partner shall be considered to be owned by such Limited Partner.
 
                                      B-43
<PAGE>   254
 
             (4) Transferee Agreement to Effect a Redemption. Any proposed
        transferee shall deliver to the General Partner a written agreement
        reasonably satisfactory to the General Partner to the effect that the
        transferee will, within six (6) months after consummation of a
        Partnership Common Units Transfer, tender its Partnership Common Units
        for Redemption in accordance with the terms of the Redemption rights
        provided in Section 8.6 hereof.
 
             (5) No Further Transfers. The transferee (other than a Designated
        Party) shall not be permitted to effect any further Transfer of the
        Partnership Units, other than to the General Partner.
 
             (6) Exception for Permitted Transfers. The conditions of Sections
        11.3.A(1) through 11.3.A(5) hereof shall not apply in the case of a
        Permitted Transfer.
 
     It is a condition to any Transfer otherwise permitted hereunder (whether or
     not such Transfer is effected during or after the first Twelve-Month
     Period) that the transferee assumes by operation of law or express
     agreement all of the obligations of the transferor Limited Partner under
     this Agreement with respect to such Transferred Partnership Interest, and
     no such Transfer (other than pursuant to a statutory merger or
     consolidation wherein all obligations and liabilities of the transferor
     Partner are assumed by a successor corporation by operation of law) shall
     relieve the transferor Partner of its obligations under this Agreement
     without the approval of the General Partner, in its sole and absolute
     discretion. Notwithstanding the foregoing, any transferee of any
     Transferred Partnership Interest shall be subject to any and all ownership
     limitations (including, without limitation, the Ownership Limit) contained
     in the Charter that may limit or restrict such transferee's ability to
     exercise its Redemption rights, including, without limitation, the
     Ownership Limit. Any transferee, whether or not admitted as a Substituted
     Limited Partner, shall take subject to the obligations of the transferor
     hereunder. Unless admitted as a Substituted Limited Partner, no transferee,
     whether by a voluntary Transfer, by operation of law or otherwise, shall
     have any rights hereunder, other than the rights of an Assignee as provided
     in Section 11.5 hereof.
 
          B. Incapacity. If a Limited Partner is subject to Incapacity, the
     executor, administrator, trustee, committee, guardian, conservator or
     receiver of such Limited Partner's estate shall have all the rights of a
     Limited Partner, but not more rights than those enjoyed by other Limited
     Partners, for the purpose of settling or managing the estate, and such
     power as the Incapacitated Limited Partner possessed to Transfer all or any
     part of its interest in the Partnership. The Incapacity of a Limited
     Partner, in and of itself, shall not dissolve or terminate the Partnership.
 
          C. Opinion of Counsel. In connection with any Transfer of a Limited
     Partner Interest, the General Partner shall have the right to receive an
     opinion of counsel reasonably satisfactory to it to the effect that the
     proposed Transfer may be effected without registration under the Securities
     Act and will not otherwise violate any federal or state securities laws or
     regulations applicable to the Partnership or the Partnership Interests
     Transferred. If, in the opinion of such counsel, such Transfer would
     require the filing of a registration statement under the Securities Act or
     would otherwise violate any federal or state securities laws or regulations
     applicable to the Partnership or the Partnership Units, the General Partner
     may prohibit any Transfer otherwise permitted under this Section 11.3 by a
     Limited Partner of Partnership Interests.
 
          D. Adverse Tax Consequences. No Transfer by a Limited Partner of its
     Partnership Interests (including any Redemption, any other acquisition of
     Partnership Units by the General Partner or any acquisition of Partnership
     Units by the Partnership) may be made to any person if (i) in the opinion
     of legal counsel for the Partnership, it would result in the Partnership
     being treated as an association taxable as a corporation, or (ii) such
     Transfer is effectuated through an "established securities market" or a
     "secondary market (or the substantial equivalent thereof)" within the
     meaning of Code Section 7704.
 
     Section 11.4  Substituted Limited Partners.
 
          A. No Limited Partner shall have the right to substitute a transferee
     (including any Designated Party or other transferees pursuant to Transfers
     permitted by Section 11.3 hereof) as a Limited Partner in its place. A
     transferee (including, but not limited to, any Designated Party) of the
     interest of a Limited
                                      B-44
<PAGE>   255
 
     Partner may be admitted as a Substituted Limited Partner only with the
     Consent of the General Partner, which Consent may be given or withheld by
     the General Partner in its sole and absolute discretion. The failure or
     refusal by the General Partner to permit a transferee of any such interests
     to become a Substituted Limited Partner shall not give rise to any cause of
     action against the Partnership or the General Partner. Subject to the
     foregoing, an Assignee shall not be admitted as a Substituted Limited
     Partner until and unless it furnishes to the General Partner (i) evidence
     of acceptance, in form and substance satisfactory to the General Partner,
     of all the terms, conditions and applicable obligations of this Agreement,
     (ii) a counterpart signature page to this Agreement executed by such
     Assignee and (iii) such other documents and instruments as may be required
     or advisable, in the sole and absolute discretion of the General Partner,
     to effect such Assignee's admission as a Substituted Limited Partner.
 
          B. A transferee who has been admitted as a Substituted Limited Partner
     in accordance with this Article 11 shall have all the rights and powers and
     be subject to all the restrictions and liabilities of a Limited Partner
     under this Agreement.
 
          C. Upon the admission of a Substituted Limited Partner, the General
     Partner shall amend Exhibit A to reflect the name, address and number of
     Partnership Units of such Substituted Limited Partner and to eliminate or
     adjust, if necessary, the name, address and number of Partnership Units of
     the predecessor of such Substituted Limited Partner.
 
     Section 11.5  Assignees. If the General Partner, in its sole and absolute
discretion, does not consent to the admission of any permitted transferee under
Section 11.3 hereof as a Substituted Limited Partner, as described in Section
11.4 hereof, such transferee shall be considered an Assignee for purposes of
this Agreement. An Assignee shall be entitled to all the rights of an assignee
of a limited partnership interest under the Act, including the right to receive
distributions from the Partnership and the share of Net Income, Net Losses and
other items of income, gain, loss, deduction and credit of the Partnership
attributable to the Partnership Units assigned to such transferee and the rights
to Transfer the Partnership Units provided in this Article 11, but shall not be
deemed to be a holder of Partnership Units for any other purpose under this
Agreement (other than as expressly provided in Section 8.6 hereof with respect
to a Qualifying Party that becomes a Tendering Party), and shall not be entitled
to effect a Consent or vote with respect to such Partnership Units on any matter
presented to the Limited Partners for approval (such right to Consent or vote,
to the extent provided in this Agreement or under the Act, fully remaining with
the transferor Limited Partner). In the event that any such transferee desires
to make a further assignment of any such Partnership Units, such transferee
shall be subject to all the provisions of this Article 11 to the same extent and
in the same manner as any Limited Partner desiring to make an assignment of
Partnership Units.
 
     Section 11.6  General Provisions.
 
          A. No Limited Partner may withdraw from the Partnership other than as
     a result of a permitted Transfer of all of such Limited Partner's
     Partnership Units in accordance with this Article 11, with respect to which
     the transferee becomes a Substituted Limited Partner, or pursuant to a
     redemption (or acquisition by the Previous General Partner) of all of its
     Partnership Units pursuant to a Redemption under Section 8.6 hereof and/or
     pursuant to any Partnership Unit Designation.
 
          B. Any Limited Partner who shall Transfer all of its Partnership Units
     in a Transfer (i) permitted pursuant to this Article 11 where such
     transferee was admitted as a Substituted Limited Partner, (ii) pursuant to
     the exercise of its rights to effect a redemption of all of its Partnership
     Units pursuant to a Redemption under Section 8.6 hereof and/or pursuant to
     any Partnership Unit Designation or (iii) to the Previous General Partner
     or the General Partner, whether or not pursuant to Section 8.6.B hereof,
     shall cease to be a Limited Partner.
 
          C. If any Partnership Unit is Transferred in compliance with the
     provisions of this Article 11, or is redeemed by the Partnership, or
     acquired by the Previous General Partner pursuant to Section 8.6 hereof, on
     any day other than the first day of a Fiscal Year, then Net Income, Net
     Losses, each item thereof and all other items of income, gain, loss,
     deduction and credit attributable to such Partnership Unit for such Fiscal
     Year shall be allocated to the transferor Partner or the Tendering Party,
     as the case may be, and, in

                                      B-45
<PAGE>   256
 
     the case of a Transfer or assignment other than a Redemption, to the
     transferee Partner (including, without limitation, the General Partner and
     the Special Limited Partner as transferees of the Previous General Partner
     in the case of an acquisition of Partnership Common Units pursuant to
     Section 8.6 hereof), by taking into account their varying interests during
     the Fiscal Year in accordance with Code Section 706(d), using the "interim
     closing of the books" method or another permissible method selected by the
     General Partner. Solely for purposes of making such allocations, each of
     such items for the calendar month in which a Transfer occurs shall be
     allocated to the transferee Partner and none of such items for the calendar
     month in which a Transfer or a Redemption occurs shall be allocated to the
     transferor Partner or the Tendering Party, as the case may be, if such
     Transfer occurs on or before the fifteenth (15th) day of the month,
     otherwise such items shall be allocated to the transferor. All
     distributions of Available Cash attributable to such Partnership Unit with
     respect to which the Partnership Record Date is before the date of such
     Transfer, assignment or Redemption shall be made to the transferor Partner
     or the Tendering Party, as the case may be, and, in the case of a Transfer
     other than a Redemption, all distributions of Available Cash thereafter
     attributable to such Partnership Unit shall be made to the transferee
     Partner.
 
          D. In addition to any other restrictions on Transfer herein contained,
     in no event may any Transfer or assignment of a Partnership Interest by any
     Partner (including any Redemption, any acquisition of Partnership Units by
     the Previous General Partner or any other acquisition of Partnership Units
     by the Partnership) be made (i) to any person or entity who lacks the legal
     right, power or capacity to own a Partnership Interest; (ii) in violation
     of applicable law; (iii) of any component portion of a Partnership
     Interest, such as the Capital Account, or rights to distributions, separate
     and apart from all other components of a Partnership Interest; (iv) in the
     event that such Transfer would cause either (a) the Previous General
     Partner to cease to comply with the REIT Requirements or (b) the General
     Partner or the Special Limited Partner to cease to qualify as a "qualified
     REIT subsidiary" (within the meaning of Code Section 856(i)(2); (v) if such
     Transfer would, in the opinion of counsel to the Partnership or the General
     Partner, cause a termination of the Partnership for federal or state income
     tax purposes (except as a result of the Redemption (or acquisition by the
     Previous General Partner) of all Partnership Common Units held by all
     Limited Partners other than the Special Limited Partner); (vi) if such
     Transfer would, in the opinion of legal counsel to the Partnership, cause
     the Partnership to cease to be classified as a partnership for federal
     income tax purposes (except as a result of the Redemption (or acquisition
     by the Previous General Partner) of all Partnership Common Units held by
     all Limited Partners other than the Special Limited Partner); (vii) if such
     Transfer would cause the Partnership to become, with respect to any
     employee benefit plan subject to Title I of ERISA, a "party-in-interest"
     (as defined in ERISA Section 3(14)) or a "disqualified person" (as defined
     in Code Section 4975(c)); (viii) if such Transfer would, in the opinion of
     legal counsel to the Partnership, cause any portion of the assets of the
     Partnership to constitute assets of any employee benefit plan pursuant to
     Department of Labor Regulations Section 2510.2-101; (ix) if such Transfer
     requires the registration of such Partnership Interest pursuant to any
     applicable federal or state securities laws; (x) if such Transfer causes
     the Partnership to become a "publicly traded partnership," as such term is
     defined in Code Section 469(k)(2) or Code 7704(b); (xi) if such Transfer
     would cause the Partnership to have more than five hundred (500) partners
     (including as partners those persons indirectly owning an interest in the
     Partnership through a partnership, limited liability company, subchapter S
     corporation or grantor trust); (xii) if such Transfer causes the
     Partnership (as opposed to the Previous General Partner or the General
     Partner) to become a reporting company under the Exchange Act; or (xiii) if
     such Transfer subjects the Partnership to regulation under the Investment
     Company Act of 1940, the Investment Advisors Act of 1940 or ERISA, each as
     amended.

                             ADMISSION OF PARTNERS
 
     Section 12.1  Admission of Successor General Partner. A successor to all of
the General Partner's General Partner Interest pursuant to Section 11.2 hereof
who is proposed to be admitted as a successor General Partner shall be admitted
to the Partnership as the General Partner, effective immediately prior to such
Transfer. Any such successor shall carry on the business of the Partnership
without dissolution. In each case, the admission shall be subject to the
successor General Partner executing and delivering to the Partnership an
acceptance of all of the terms and conditions of this Agreement and such other
documents or instruments as may be required to effect the admission.
 
     Section 12.2  Admission of Additional Limited Partners.
 
          A. After the admission to the Partnership of an Original Limited
     Partner on the date hereof, a Person (other than an existing Partner) who
     makes a Capital Contribution to the Partnership in accordance with this
     Agreement shall be admitted to the Partnership as an Additional Limited
     Partner only upon furnishing to the General Partner (i) evidence of
     acceptance, in form and substance satisfactory to the General Partner, of
     all of the terms and conditions of this Agreement, including, without
     limitation, the power of attorney granted in Section 2.4 hereof, (ii) a
     counterpart signature page to this Agreement executed by such Person and
     (iii) such other documents or instruments as may be required in the sole
     and absolute discretion of the General Partner in order to effect such
     Person's admission as an Additional Limited Partner.
 
          B. Notwithstanding anything to the contrary in this Section 12.2, no
     Person shall be admitted as an Additional Limited Partner without the
     consent of the General Partner, which consent may be given or withheld in
     the General Partner's sole and absolute discretion. The admission of any
     Person as an Additional Limited Partner shall become effective on the date
     upon which the name of such Person is recorded on the books and records of
     the Partnership, following the consent of the General Partner to such
     admission.
 
          C. If any Additional Limited Partner is admitted to the Partnership on
     any day other than the first day of a Fiscal Year, then Net Income, Net
     Losses, each item thereof and all other items of income, gain, loss,
     deduction and credit allocable among Partners and Assignees for such Fiscal
     Year shall be allocated among such Additional Limited Partner and all other
     Partners and Assignees by taking into account their varying interests
     during the Fiscal Year in accordance with Code Section 706(d), using the
     "interim closing of the books" method or another permissible method
     selected by the General Partner. Solely for purposes of making such
     allocations, each of such items for the calendar month in which an
     admission of any Additional Limited Partner occurs shall be allocated among
     all the Partners and Assignees including such Additional Limited Partner,
     in accordance with the principles described in Section 11.6.C hereof. All
     distributions of Available Cash with respect to which the Partnership
     Record Date is before the date of such admission shall be made solely to
     Partners and Assignees other than the Additional Limited Partner, and all
     distributions of Available Cash thereafter shall be made to all the
     Partners and Assignees including such Additional Limited Partner.
 
     Section 12.3  Amendment of Agreement and Certificate of Limited
Partnership. For the admission to the Partnership of any Partner, the General
Partner shall take all steps necessary and appropriate under the Act to amend
the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
and may for this purpose exercise the power of attorney granted pursuant to
Section 2.4 hereof.
 
     Section 12.4  Admission of Initial Limited Partners. The Persons listed on
Exhibit A as limited partners of the Partnership shall be admitted to the
Partnership as Limited Partners upon their execution and delivery of this
Agreement.

     Section 12.5  Limit on Number of Partners. No Person shall be admitted to
the Partnership as an Additional Limited Partner if the effect of such admission
would be to cause the Partnership to have a number of Partners (including as
Partners for this purpose those Persons indirectly owning an interest in the
Partnership through another partnership, a limited liability company, a
subchapter S corporation or a grantor trust) that would cause the Partnership to
become a reporting company under the Exchange Act.

                    DISSOLUTION, LIQUIDATION AND TERMINATION
 
     Section 13.1  Dissolution. The Partnership shall not be dissolved by the
admission of Substituted Limited Partners or Additional Limited Partners or by
the admission of a successor General Partner in accordance with the terms of
this Agreement. Upon the withdrawal of the General Partner, any successor
General Partner shall continue the business of the Partnership without
dissolution. However, the Partnership shall dissolve, and its affairs shall be
wound up, upon the first to occur of any of the following (each a "Liquidating
Event"):
 
          A. the expiration of its term as provided in Section 2.5 hereof;
 
          B. an event of withdrawal, as defined in the Act (including, without
     limitation, bankruptcy), of the sole General Partner unless, within ninety
     (90) days after the withdrawal, a "majority in interest" (as such phrase is
     used in Section 17-801(3) of the Act) of the remaining Partners agree in
     writing, in their sole and absolute discretion, to continue the business of
     the Partnership and to the appointment, effective as of the date of
     withdrawal, of a successor General Partner;
 
          C. an election to dissolve the Partnership made by the General Partner
     in its sole and absolute discretion, with or without the Consent of the
     Limited Partners;
 
          D. entry of a decree of judicial dissolution of the Partnership
     pursuant to the provisions of the Act;
 
          E. the occurrence of a Terminating Capital Transaction;
 
          F. the Redemption (or acquisition by the Previous General Partner, the
     General Partner and/or the Special Limited Partner) of all Partnership
     Common Units other than Partnership Common Units held by the General
     Partner or the Special Limited Partner; or
 
          G. the Redemption (or acquisition by the General Partner) of all
     Partnership Common Units other than Partnership Common Units held by the
     General Partner.
 
     Section 13.2  Winding Up.
 
          A. Upon the occurrence of a Liquidating Event, the Partnership shall
     continue solely for the purposes of winding up its affairs in an orderly
     manner, liquidating its assets and satisfying the claims of its creditors
     and Partners. After the occurrence of a Liquidating Event, no Partner shall
     take any action that is inconsistent with, or not necessary to or
     appropriate for, the winding up of the Partnership's business and affairs.
     The General Partner (or, in the event that there is no remaining General
     Partner or the General Partner has dissolved, become bankrupt within the
     meaning of the Act or ceased to operate, any Person elected by a Majority
     in Interest of the Limited Partners (the General Partner or such other
     Person being referred to herein as the "Liquidator")) shall be responsible
     for overseeing the winding up and dissolution of the Partnership and shall
     take full account of the Partnership's liabilities and property, and the
     Partnership property shall be liquidated as promptly as is consistent with
     obtaining the fair value thereof, and the proceeds therefrom (which may, to
     the extent determined by the General Partner, include shares of stock in
     the Previous General Partner) shall be applied and distributed in the
     following order:
 
             (1) First, to the satisfaction of all of the Partnership's debts
        and liabilities to creditors other than the Partners and their Assignees
        (whether by payment or the making of reasonable provision for payment
        thereof);

                                      B-48
<PAGE>   259
 
             (2) Second, to the satisfaction of all of the Partnership's debts
        and liabilities to the General Partner (whether by payment or the making
        of reasonable provision for payment thereof), including, but not limited
        to, amounts due as reimbursements under Section 7.4 hereof;
 
             (3) Third, to the satisfaction of all of the Partnership's debts
        and liabilities to the other Partners and any Assignees (whether by
        payment or the making of reasonable provision for payment thereof); and
 
             (4) Subject to the terms of any Partnership Unit Designation, the
        balance, if any, to the General Partner, the Limited Partners and any
        Assignees in accordance with and in proportion to their positive Capital
        Account balances, after giving effect to all contributions,
        distributions and allocations for all periods.
 
     The General Partner shall not receive any additional compensation for any
     services performed pursuant to this Article 13.
 
          B. Notwithstanding the provisions of Section 13.2.A hereof that
     require liquidation of the assets of the Partnership, but subject to the
     order of priorities set forth therein, if prior to or upon dissolution of
     the Partnership the Liquidator determines that an immediate sale of part or
     all of the Partnership's assets would be impractical or would cause undue
     loss to the Partners, the Liquidator may, in its sole and absolute
     discretion, defer for a reasonable time the liquidation of any assets
     except those necessary to satisfy liabilities of the Partnership (including
     to those Partners as creditors) and/or distribute to the Partners, in lieu
     of cash, as tenants in common and in accordance with the provisions of
     Section 13.2.A hereof, undivided interests in such Partnership assets as
     the Liquidator deems not suitable for liquidation. Any such distributions
     in kind shall be made only if, in the good faith judgment of the
     Liquidator, such distributions in kind are in the best interest of the
     Partners, and shall be subject to such conditions relating to the
     disposition and management of such properties as the Liquidator deems
     reasonable and equitable and to any agreements governing the operation of
     such properties at such time. The Liquidator shall determine the fair
     market value of any property distributed in kind using such reasonable
     method of valuation as it may adopt.
 
          C. In the event that the Partnership is "liquidated" within the
     meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be
     made pursuant to this Article 13 to the Partners and Assignees that have
     positive Capital Accounts in compliance with Regulations Section
     1.704-1(b)(2)(ii)(b)(2) to the extent of, and in proportion to, positive
     Capital Account balances. If any Partner has a deficit balance in its
     Capital Account (after giving effect to all contributions, distributions
     and allocations for all taxable years, including the year during which such
     liquidation occurs), such Partner shall have no obligation to make any
     contribution to the capital of the Partnership with respect to such
     deficit, and such deficit shall not be considered a debt owed to the
     Partnership or to any other Person for any purpose whatsoever. In the sole
     and absolute discretion of the General Partner or the Liquidator, a pro
     rata portion of the distributions that would otherwise be made to the
     Partners pursuant to this Article 13 may be withheld or escrowed to provide
     a reasonable reserve for Partnership liabilities (contingent or otherwise)
     and to reflect the unrealized portion of any installment obligations owed
     to the Partnership, provided that such withheld or escrowed amounts shall
     be distributed to the General Partner and Limited Partners in the manner
     and order of priority set forth in Section 13.2.A hereof as soon as
     practicable.
 
     Section 13.3  Deemed Distribution and Recontribution. Notwithstanding any
other provision of this Article 13, in the event that the Partnership is
liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), but
no Liquidating Event has occurred, the Partnership's Property shall not be
liquidated, the Partnership's liabilities shall not be paid or discharged and
the Partnership's affairs shall not be wound up. Instead, for federal income tax
purposes the Partnership shall be deemed to have distributed the Property in
kind to the Partners and the Assignees, who shall be deemed to have assumed and
taken such Property subject to all Partnership liabilities, all in accordance
with their respective Capital Accounts. Immediately thereafter, the Partners and
the Assignees shall be deemed to have recontributed the Partnership

                                      B-49
<PAGE>   260
 
Property in kind to the Partnership, which shall be deemed to have assumed and
taken such Property subject to all such liabilities; provided, however, that
nothing in this Section 13.3 shall be deemed to have constituted any Assignee as
a Substituted Limited Partner without compliance with the provisions of Section
11.4 hereof.
 
     Section 13.4  Rights of Limited Partners. Except as otherwise provided in
this Agreement, (a) each Limited Partner shall look solely to the assets of the
Partnership for the return of its Capital Contribution, (b) no Limited Partner
shall have the right or power to demand or receive property other than cash from
the Partnership and (c) no Limited Partner shall have priority over any other
Limited Partner as to the return of its Capital Contributions, distributions or
allocations.
 
     Section 13.5  Notice of Dissolution. In the event that a Liquidating Event
occurs or an event occurs that would, but for an election or objection by one or
more Partners pursuant to Section 13.1 hereof, result in a dissolution of the
Partnership, the General Partner shall, within thirty (30) days thereafter,
provide written notice thereof to each of the Partners and, in the General
Partner's sole and absolute discretion or as required by the Act, to all other
parties with whom the Partnership regularly conducts business (as determined in
the sole and absolute discretion of the General Partner), and the General
Partner may, or, if required by the Act, shall, publish notice thereof in a
newspaper of general circulation in each place in which the Partnership
regularly conducts business (as determined in the sole and absolute discretion
of the General Partner).
 
     Section 13.6  Cancellation of Certificate of Limited Partnership. Upon the
completion of the liquidation of the Partnership cash and property as provided
in Section 13.2 hereof, the Partnership shall be terminated, a certificate of
cancellation shall be filed with the State of Delaware, all qualifications of
the Partnership as a foreign limited partnership or association in jurisdictions
other than the State of Delaware shall be cancelled, and such other actions as
may be necessary to terminate the Partnership shall be taken.
 
     Section 13.7  Reasonable Time for Winding-Up. A reasonable time shall be
allowed for the orderly winding-up of the business and affairs of the
Partnership and the liquidation of its assets pursuant to Section 13.2 hereof,
in order to minimize any losses otherwise attendant upon such winding-up, and
the provisions of this Agreement shall remain in effect between the Partners
during the period of liquidation.

     PROCEDURES FOR ACTIONS AND CONSENTS OF PARTNERS; AMENDMENTS; MEETINGS
 
     Section 14.1  Procedures for Actions and Consents of Partners. The actions
requiring consent or approval of Limited Partners pursuant to this Agreement,
including Section 7.3 hereof, or otherwise pursuant to applicable law, are
subject to the procedures set forth in this Article 14.
 
     Section 14.2  Amendments. Amendments to this Agreement may be proposed by
the General Partner or by a Majority in Interest of the Limited Partners.
Following such proposal, the General Partner shall submit any proposed amendment
to the Limited Partners. The General Partner shall seek the written consent of
the Limited Partners on the proposed amendment or shall call a meeting to vote
thereon and to transact any other business that the General Partner may deem
appropriate. For purposes of obtaining a written consent, the General Partner
may require a response within a reasonable specified time, but not less than
fifteen (15) days, and failure to respond in such time period shall constitute a
consent that is consistent with the General Partner's recommendation with
respect to the proposal; provided, however, that an action shall become
effective at such time as requisite consents are received even if prior to such
specified time.
 
     Section 14.3  Meetings of the Partners.
 
          A. Meetings of the Partners may be called by the General Partner and
     shall be called upon the receipt by the General Partner of a written
     request by a Majority in Interest of the Limited Partners. The call shall
     state the nature of the business to be transacted. Notice of any such
     meeting shall be given to all Partners not less than seven (7) days nor
     more than thirty (30) days prior to the date of such meeting. Partners may
     vote in person or by proxy at such meeting. Whenever the vote or Consent of
     Partners is permitted or required under this Agreement, such vote or
     Consent may be given at a meeting of Partners or may be given in accordance
     with the procedure prescribed in Section 14.3.B hereof.

          B. Any action required or permitted to be taken at a meeting of the
     Partners may be taken without a meeting if a written consent setting forth
     the action so taken is signed by a majority of the Percentage Interests of
     the Partners (or such other percentage as is expressly required by this
     Agreement for the action in question). Such consent may be in one
     instrument or in several instruments, and shall have the same force and
     effect as a vote of a majority of the Percentage Interests of the Partners
     (or such other percentage as is expressly required by this Agreement). Such
     consent shall be filed with the General Partner. An action so taken shall
     be deemed to have been taken at a meeting held on the effective date so
     certified.
 
          C. Each Limited Partner may authorize any Person or Persons to act for
     it by proxy on all matters in which a Limited Partner is entitled to
     participate, including waiving notice of any meeting, or voting or
     participating at a meeting. Every proxy must be signed by the Limited
     Partner or its attorney-in-fact. No proxy shall be valid after the
     expiration of eleven (11) months from the date thereof unless otherwise
     provided in the proxy (or there is receipt of a proxy authorizing a later
     date). Every proxy shall be revocable at the pleasure of the Limited
     Partner executing it, such revocation to be effective upon the
     Partnership's receipt of written notice of such revocation from the Limited
     Partner executing such proxy.
 
          D. Each meeting of Partners shall be conducted by the General Partner
     or such other Person as the General Partner may appoint pursuant to such
     rules for the conduct of the meeting as the General Partner or such other
     Person deems appropriate in its sole and absolute discretion. Without
     limitation, meetings of Partners may be conducted in the same manner as
     meetings of the General Partner's shareholders and may be held at the same
     time as, and as part of, the meetings of the General Partner's
     shareholders.

     Section 15.1  Addresses and Notice. Any notice, demand, request or report

Agreement shall be in writing and shall be deemed given or made when delivered

written communication (including by telecopy, facsimile, or commercial courier
service) to the Partner or Assignee at the address set forth in Exhibit A or
such other address of which the Partner shall notify the General Partner in

          B. The restrictions, conditions and other limitations on the rights
     and benefits of the Limited Partners contained in this Agreement, and the
     duties, covenants and other requirements of performance or notice by the
     Limited Partners, are for the benefit of the Partnership and, except for an
     obligation to pay money to the Partnership, may be waived or relinquished
     by the General Partner, in its sole and absolute discretion, on behalf of
     the Partnership in one or more instances from time to time and at any time;
     provided, however, that any such waiver or relinquishment may not be made
     if it would have the effect of (i) creating liability for any other Limited
     Partner, (ii) causing the Partnership to cease to qualify as a limited
     partnership, (iii) reducing the amount of cash otherwise distributable to
     the Limited Partners, (iv) resulting in the classification of the
     Partnership as an association or publicly traded partnership taxable as a
     corporation or (v) violating the Securities Act, the Exchange Act or any
     state "blue sky" or other securities laws; provided, further, that any
     waiver relating to compliance with the Ownership Limit or other
     restrictions in the Charter shall be made and shall be effective only as
     provided in the Charter.
 
     Section 15.7  Counterparts. This Agreement may be executed in counterparts,
all of which together shall constitute one agreement binding on all the parties
hereto, notwithstanding that all such parties are not signatories to the
original or the same counterpart. Each party shall become bound by this
Agreement immediately upon affixing its signature hereto.
 
     Section 15.8  Applicable Law. This Agreement shall be construed and
enforced in accordance with and governed by the laws of the State of Delaware,
without regard to the principles of conflicts of law. In the event of a conflict
between any provision of this Agreement and any non-mandatory provision of the
Act, the provisions of this Agreement shall control and take precedence.
 
     Section 15.9  Entire Agreement. This Agreement contains all of the
understandings and agreements between and among the Partners with respect to the
subject matter of this Agreement and the rights, interests and obligations of
the Partners with respect to the Partnership.
 
     Section 15.10  Invalidity of Provisions. If any provision of this Agreement
is or becomes invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein shall
not be affected thereby.
 
     Section 15.11  Limitation to Preserve REIT Status. Notwithstanding anything
else in this Agreement, to the extent that the amount paid, credited,
distributed or reimbursed by the Partnership to any REIT Partner or its
officers, directors, employees or agents, whether as a reimbursement, fee,
expense or indemnity (a "REIT Payment"), would constitute gross income to the
REIT Partner for purposes of Code Section 856(c)(2) or Code Section 856(c)(3),
then, notwithstanding any other provision of this Agreement, the amount of such
REIT Payments, as selected by the General Partner in its discretion from among
items of potential distribution, reimbursement, fees, expenses and indemnities,
shall be reduced for any Fiscal Year so that the REIT Payments, as so reduced,
for or with respect to such REIT Partner shall not exceed the lesser of:
 
          (i) an amount equal to the excess, if any, of (a) four and nine-tenths
     percent (4.9%) of the REIT Partner's total gross income (but excluding the
     amount of any REIT Payments) for the Fiscal Year that is described in
     subsections (A) through (H) of Code Section 856(c)(2) over (b) the amount
     of gross income (within the meaning of Code Section 856(c)(2)) derived by
     the REIT Partner from sources other than those described in subsections (A)
     through (H) of Code Section 856(c)(2) (but not including the amount of any
     REIT Payments); or
 
          (ii) an amount equal to the excess, if any, of (a) twenty-four percent
     (24%) of the REIT Partner's total gross income (but excluding the amount of
     any REIT Payments) for the Fiscal Year that is described in subsections (A)
     through (I) of Code Section 856(c)(3) over (b) the amount of gross income
     (within the meaning of Code Section 856(c)(3)) derived by the REIT Partner
     from sources other than those described in subsections (A) through (I) of
     Code Section 856(c)(3) (but not including the amount of any REIT Payments);
 
                                      B-52
<PAGE>   263
 
provided, however, that REIT Payments in excess of the amounts set forth in
clauses (i) and (ii) above may be made if the General Partner, as a condition
precedent, obtains an opinion of tax counsel that the receipt of such excess
amounts shall not adversely affect the REIT Partner's ability to qualify as a
REIT. To the extent that REIT Payments may not be made in a Fiscal Year as a
consequence of the limitations set forth in this Section 15.11, such REIT
Payments shall carry over and shall be treated as arising in the following
Fiscal Year. The purpose of the limitations contained in this Section 15.11 is
to prevent any REIT Partner from failing to qualify as a REIT under the Code by
reason of such REIT Partner's share of items, including distributions,
reimbursements, fees, expenses or indemnities, receivable directly or indirectly
from the Partnership, and this Section 15.11 shall be interpreted and applied to
effectuate such purpose.
 
     Section 15.12  No Partition. No Partner nor any successor-in-interest to a
Partner shall have the right while this Agreement remains in effect to have any
property of the Partnership partitioned, or to file a complaint or institute any
proceeding at law or in equity to have such property of the Partnership
partitioned, and each Partner, on behalf of itself and its successors and
assigns hereby waives any such right. It is the intention of the Partners that
the rights of the parties hereto and their successors-in-interest to Partnership
property, as among themselves, shall be governed by the terms of this Agreement,
and that the rights of the Partners and their successors-in-interest shall be
subject to the limitations and restrictions as set forth in this Agreement.
 
     Section 15.13  No Third-Party Rights Created Hereby. The provisions of this
Agreement are solely for the purpose of defining the interests of the Partners,
inter se; and no other person, firm or entity (i.e., a party who is not a
signatory hereto or a permitted successor to such signatory hereto) shall have
any right, power, title or interest by way of subrogation or otherwise, in and
to the rights, powers, title and provisions of this Agreement. No creditor or
other third party having dealings with the Partnership shall have the right to
enforce the right or obligation of any Partner to make Capital Contributions or
loans to the Partnership or to pursue any other right or remedy hereunder or at
law or in equity. None of the rights or obligations of the Partners herein set
forth to make Capital Contributions or loans to the Partnership shall be deemed
an asset of the Partnership for any purpose by any creditor or other third
party, nor may any such rights or obligations be sold, transferred or assigned
by the Partnership or pledged or encumbered by the Partnership to secure any
debt or other obligation of the Partnership or any of the Partners.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Baywood Partners, Ltd. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System". There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   269
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   270
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $4,640.63 per unit for the six
     months ended June 30, 1998 (equivalent to $9,281.26 on an annual basis). We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $       per
     year on the number of Tax-Deferral   % Preferred OP Units or distributions
     of $     per year on the number of Tax-Deferral Common OP Units that you
     would receive in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single property to holding an
     interest in an operating business that owns and manages a large portfolio
     of properties, with risks that do not exist for your partnership. You
     should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   272
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   275
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary dies not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
property to an interest in a partnership that invests in and manages a large
portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   276
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   277
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   278
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   279
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Another option for liquidation of your investment would
     be to sell your units in a private transaction. Any such sale could be at a
     very substantial discount from your pro rata share of the fair market value
     of your partnership's property and might involve significant expense and
     delay.
 
        Continuation of Your Partnership Without the Offer. A second alternative
     would be for your partnership to continue its business without our offer. A
     number of advantages could result from the continued operation of your
     partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.

  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."
 
TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the

       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.

     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your
 
                                      S-15
<PAGE>   283
 
     property's physical condition, location and above-market mortgage interest
rates. In addition, we considered the recent decline in the market for equity
securities, including those of REITs and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely-accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
                                      S-16
<PAGE>   284
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership has no such
limitation.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for
 
                                      S-17
<PAGE>   285
 
managing your partnership's property and (ii) our desire to purchase units at a
low price and your desire to sell units at a high price. Your general partner
makes no recommendation as to whether you should tender or refrain from
tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual management fee equal to 5% of the Net Cash Flow (as defined in your
partnership's agreement of limited partnership) of your partnership and may
receive reimbursement for expenses generated in its capacity as general partner.
The property manager received management fees of $64,690 in 1996, $65,846 in
1997 and $32,547 for the first six months of 1998. We have no current intention
of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Baywood Partners, Ltd. is an Alabama
limited partnership which was formed on January 1, 1979 for the purpose of
owning and operating an apartment property located in Gretna, Louisiana, known
as "Baywood Apartments." In 1979, it completed a private placement of units that
raised net proceeds of approximately $1,984,000. Baywood Apartments consists of
226 apartment units. Your partnership has no employees.
 
     Property Management. Since November, 1992, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $4,358,066, payable to FNMA, which bears
interest at a rate of 7.83%. The mortgage debt is due in October, 2003. Your
 
                                      S-18
<PAGE>   286
 
partnership also has a second mortgage note outstanding of $142,290, on the same
terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multihousing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   294
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single property. In contrast,
the AIMCO Operating Partnership is in the business of acquiring, marketing,
managing and operating a large portfolio of apartment properties. While
diversification of assets may reduce certain risks of investment attributable to
a single property or entity, there can be no assurance as to the value or
performance of our securities or our portfolio of properties as compared to the
value of your units or your partnership. Proceeds of future asset sales or
refinancings by the AIMCO Operating Partnership generally will be reinvested
rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   295
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $4,640.63 per unit (equivalent
to $9,281.26 on an annualized basis). This is equivalent to distributions of
$       per year on the number of tax-deferral        % Preferred OP Units, or
distributions of $       per year on the number of tax deferral Common OP Units,
that you would receive in exchange for each of your partnership's units.
Therefore, distributions with respect to the Preferred OP Units and Common OP
Units that we are offering are expected to be        , immediately following our
offer, than the distributions with respect to your units. See "Comparison of
Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service revised its outlook for the ratings of AIMCO from
stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO, and confirmed its previous ratings related to AIMCO's
preferred stock and debt in its shelf registration statement. Moody's indicated
that its rating action continues to reflect AIMCO's increasing leveraged
profile, including high levels of secured debt and preferred stock, limited
financial flexibility and integration risks resulting from the merger with
Insignia. Moody's also noted AIMCO's high level of encumbered properties and
material investments in loans to highly leveraged partnerships in which AIMCO
owns a general partnership interest. At the same time, Moody's confirmed its
existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   297
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Another option for liquidation would be to sell
your units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one
 
                                      S-30
<PAGE>   298
 
class of outstanding Partnership Preferred Units has prior distribution rights
and the Tax-Deferral   % Preferred Units rank equal to six other outstanding
classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   300
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   301
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   302
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   303
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   304
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   305
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

        (f) a tender or exchange offer for any units shall have been commenced

to exercise any of the foregoing rights shall not be deemed a waiver of any such

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   308
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $       .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   310
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   311
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   312
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   313
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if

shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a

                                                             of Class I Preferred Stock. The redemption price for
                                                             the Class I Preferred Stock (other than any portion

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   318
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   319
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   321
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   322
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $4,640.63 (equivalent to $9,281.26
     on an annualized basis). This is equivalent to distributions of $       per
     year on the number of tax-deferral        % Preferred OP Units, or
     distributions of $       per year on the number of tax deferral Common OP
     Units, that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   323
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual management fee equal to 5% of the Net Cash Flow (as defined in your
partnership's agreement of limited partnership) from your partnership and may
receive reimbursement for expenses generated in its capacity as general partner.
The property manager received management fees of $64,690 in 1996, $65,846 in
1997 and $32,547 for the first six months of 1998. The AIMCO Operating
Partnership has no current intention of changing the fee structure for the
manager of your partnership property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Baywood Partners, Ltd. is an Alabama limited partnership which raised net
proceeds of approximately $1,984,000 in 1979 through a private offering. The
promoter for the private offering of your partnership was Angeles Properties,
Inc. Insignia acquired your partnership in November, 1992. AIMCO acquired
Insignia in October, 1998. There are currently a total of 35 limited partners of
your partnership and a total of 32 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the multi-family property described
below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on January 1, 1979 for the purpose of owning
and operating an apartment property located in Gretna, Louisiana, known as
"Baywood Apartments." Your partnership's property consists of 226 apartment
units. There are 104 one-bedroom apartments, 76 two-bedroom apartments and 46
three-bedroom apartments. Your partnership's property had an average occupancy
rate of approximately 96.02% in 1996 and 96.02% in 1997.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November, 1992, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $64,690, $65,846 and $32,547, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2015
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $4,358,066, payable to FNMA, which bears interest at a rate of
7.83%. The mortgage debt is due in October, 2003. Your partnership also has a
second mortgage note outstanding of $142,290, on the same terms as the current
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Income
 
     Your partnership recognized net income of $103,558 for the six months ended
June 30, 1998, compared to $132,679 for the six months ended June 30, 1997. The
decrease in net income of $29,121, or 21.95% is due to a decrease in rental
revenues and an increase in operating expenses. These factors are discussed in
more detail in the following paragraphs.

$654,689 for the six months ended June 30, 1998, compared to $668,107 for the

expenses totaled $32,547 for the six months ended June 30, 1998, compared to

     General and Administrative Expenses
 
     General and administrative expenses totaled $25,099 for the six months
ended June 30, 1998 compared to $11,865 for the six months ended June 30, 1997,
an increase of $13,234 or 111.54% The increase is primarily due to an increase
in the partnership asset management fee.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $176,887 for the six months ended June 30, 1998, compared to
$179,171 for the six months ended June 30, 1997, a decrease of $2,284, or 1.27%.

31, 1996

decrease in net income of $6,620, or 3.92%.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,324,481 for the year ended December 31, 1997, compared to $1,325,546 for the

     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, property taxes and insurance, totaled
$593,179 for the year ended December 31, 1997, compared to $590,698 for the year
ended December 31, 1996, an increase of $2,481 or 0.42%. Management expenses
totaled $65,846 for the year ended December 31, 1997, compared to $64,690 for
the year ended December 31, 1996, an increase of $1,156, or 1.79%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $36,996 for the year ended
December 31, 1997 compared to $50,012 for the year ended December 31, 1996, a
decrease of $13,016 or 26.03%.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $386,668 for the year ended December 31, 1997, compared to
$389,778 for the year ended December 31, 1996, a decrease of $3,110, or 0.80%.
 
     Comparison of the Year Ended December 31, 1996 to the Year Ended December
31, 1995
 
     Net Income
 
     Your partnership recognized net income of $168,889 for the year ended
December 31, 1996, compared to $135,571 for the year ended December 31, 1995.
The increase in net income of $33,318, or 24.58% was primarily the result of an
increase in rental revenues and a decrease in depreciation offset by an increase
in operating expenses. The decrease in depreciation is due to some assets
becoming fully depreciated in 1995. These factors are discussed in more detail
in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,325,546 for the year ended December 31, 1996, compared to $1,297,874 for the
year ended December 31, 1995, an increase of $27,672, or 2.13%.
 
     Expenses

received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, property taxes and insurance, totaled
$590,698 for the year ended December 31, 1996, compared to $519,148 for the year
ended December 31, 1995. The increase of $71,550 or 13.78%, is primarily due to
expenses incurred for paving repairs and new floor coverings and appliances at
the property. Management expenses totaled $64,690 for the year ended December
31, 1996, compared to $64,085 for the year ended December 31, 1995, an increase
of $605, or 0.94%.

     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $389,778 for the year ended December 31, 1996, compared to
$394,004 for the year ended December 31, 1995, a decrease of $4,226, or 1.07%.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $320,795 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
Partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Your partnership's agreement of
limited partnership does not limit the liability of the general partner to your
partnership or the limited partners for any act performed in its capacity as
general partner. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest".
 
     Under your partnership's agreement of limited partnership, your partnership
will indemnify and save harmless the general partner of your partnership, its
officers, directors, employees, affiliates, designees and nominees from any loss
or damage, including legal fees and expenses and amounts paid in settlement,
incurred by any of them on behalf of your partnership or in furtherance of your
partnership's interest, provided that the general partner or other person sued
will not be entitled to indemnification for losses sustained by reason of its
negligence, gross negligence, willful misconduct or breach of fiduciary
obligations. As part of its assumption of liabilities in the consolidation,
AIMCO will indemnify the general partner of your partnership and their
affiliates for periods prior to and following the consolidation to the extent of
the indemnity under the terms of your partnership's agreement of limited
partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partner of your partnership or any other indemnified person.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The
original cost per unit was $62,000.

</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for
 
                                      S-77
<PAGE>   345
 
tax purposes. However, the general partner of your partnership does not monitor
or regularly receive or maintain information regarding the prices at which
secondary sale transactions in the units have been effectuated. The general
partner of your partnership estimates, based solely on the transfer records of
your partnership (or your partnership's transfer agent), that there have been no
units transferred in sale transactions (excluding transactions believed to be
between related parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in respect of its capacity as general partner of
your partnership as described in the following table:

general partner of your partnership, or the compensation paid to the property
manager or AIMCO and its affiliates.

          NOTES TO CONDENSED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Baywood Partners,
Limited as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with the accounting basis for federal income
tax reporting. Accordingly, they do not include all the information and
footnotes required by the accounting basis for federal income tax reporting for
complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Baywood Partners, Limited:
 
     We have audited the consolidated statement of assets, liabilities and
partners' deficit -- income tax basis of Baywood Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1997, and
the related consolidated statements of revenues and expenses and changes in
partners' deficit -- income tax basis and cash flows -- income tax basis for the
year then ended. These consolidated financial statements are the responsibility
of the partnership's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting Baywood Partners, Limited uses for Federal
income tax purposes, which is a comprehensive basis of accounting other than
generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Baywood
Partners, Limited and its limited partnership interest as of December 31, 1997,
and the results of their operations and their cash flows for the year then
ended, on the basis of accounting described in Note A.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of Baywood
Partners, Limited (the "Partnership"), and its Limited Partnership interest in
Baywood Apartments (the "Project Partnership"). The Partnership was organized
solely to invest in the Project Partnership. The Project Partnership owns and
operates a 226 unit apartment complex located in Jefferson Parish, Louisiana.
 
     The Partnership was organized as an Alabama limited partnership on February
15, 1979. The General Partner of the Partnership is Angeles Properties, Inc.
("API"), which acts as a general partner in other limited partnerships and is an
affiliate of Angeles Investment Properties, Inc. ("AIPI"), the general partner
of the Project Partnership. Pursuant to the terms of the Agreement and Amended
Certificate of Limited Partnership (the "Agreement"), API has contributed
$100,000 to the Partnership for which it is entitled to a 1% operating interest
in the profits, losses, credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $1,936,200.
Pursuant to the terms of the Agreement, the limited partners will receive a 99%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership had made capital contributions of $1,442,000 to the Project
Partnership and is entitled to a 99% interest in the operating profits, losses,
credits and cash distributions of the Project Partnership. AIPI is entitled to
the remaining 1% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership's tax returns. The tax basis used differs from GAAP primarily
because on the tax basis (1) certain rental income received in advance is
recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("ACRS") instead of over the estimated lives of
the assets, (3) syndication costs are carried at their original value, instead
of being amortized over the estimated life of assets, and (4) income is recorded
at the partnership level based on the partnership agreement and the Internal
Revenue Code instead of being recorded based on the percentage of ownership
interest.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or losses and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1997 include deferred loan costs of $111,612
which are amortized over the term of the related borrowing. Deferred costs are
shown net of accumulated amortization. Also included in other assets at December
31, 1997 are syndication costs of $194,045 which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers cash and
highly liquid investments, with an original maturity of three months or less
when purchased, to be cash and cash equivalents.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 were $98,611 and consist of
a reserve escrow established with a portion of the proceeds of the loan. The
funds are used for certain repair work, debt service, expenses and property
taxes or insurance. The funds in the reserve escrow exceed the minimum balance
required to be maintained by the lender during the term of the loan.
 
NOTE C -- MORTGAGE NOTES PAYABLE
 
     Mortgage notes payable at December 31, 1997 consist of the following:

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid principal
balance at the time of payment or the present value of the excess of interest
which would be incurred at the stated rate under the notes over the interest
which would be incurred at the Treasury constant maturity for U.S. Government
obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the general partners for the
management and administration of all partnership activities. The Project
Partnership is obligated to pay a property management fee equal to 5% of gross
monthly collections. In addition to the management fee, the partnership
agreement provides for payments to general partners of a partnership
administration fee and reimbursement of certain expenses incurred by general
partners on behalf of the Partnership and the Project Partnership.
 
     Transactions with the General Partner and its affiliates are as follows:

                                                               1997

Property management fee.....................................  $65,846
Reimbursement for services to affiliates....................  $29,742
Construction oversight reimbursements.......................  $ 3,456
</TABLE>
 
     For the period from January 19, 1996, to August 31, 1997 the Partnership
insured its properties under a master policy through an agency and insurer
unaffiliated with the General Partner. An affiliate of the General Partner
acquired, in the acquisition of a business, certain financial obligations from
an insurance agency which was later acquired by the agent who placed the master
policy. The agent assumed the financial obligations to the affiliate of the
General Partner, who receives payments on these obligations from the agent. The
amount of the Partnership's insurance premiums accruing to the benefit of the
affiliate of the General Partner by virtue of the agent's obligations was not
significant.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Baywood Partners, Limited:
 
     We have audited the consolidated statement of assets, liabilities and
partners' deficit -- income tax basis of Baywood Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1996, and
the related consolidated statements of revenues and expenses and changes in
partners' deficit -- income tax basis and cash flows -- income tax basis for the
year then ended. These consolidated financial statements are the responsibility
of the partnership's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting Baywood Partners, Limited uses for Federal
income tax purposes, which is a comprehensive basis of accounting other than
generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Baywood
Partners, Limited and its limited partnership interest as of December 31, 1996,
and the results of their operations and their cash flows for the year then
ended, on the basis of accounting described in Note A.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of Baywood
Partners, Limited (the "Partnership"), and its Limited Partnership interest in
Baywood Apartments (the "Project Partnership"). The Partnership was organized
solely to invest in the Project Partnership. The Project Partnership owns and
operates a 226 unit apartment complex located in Jefferson Parish, Louisiana.
 
     The Partnership was organized as an Alabama limited partnership on February
15, 1979. The General Partner of the Partnership is Angeles Properties, Inc.
("API"), which acts as a general partner in other limited partnerships and is an
affiliate of Angeles Investment Properties, Inc. ("AIPI"), the general partner
of the Project Partnership. Pursuant to the terms of the Agreement and Amended
Certificate of Limited Partnership (the "Agreement"), API has contributed
$100,000 to the Partnership for which it is entitled to a 1% operating interest
in the profits, losses, credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $1,936,200.
Pursuant to the terms of the Agreement, the limited partners will receive a 99%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership had made capital contributions of $1,442,000 to the Project
Partnership and is entitled to a 99% interest in the operating profits, losses,
credits and cash distributions of the Project Partnership. AIPI is entitled to
the remaining 1% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership's tax returns. The tax basis used differs from GAAP primarily
because on the tax basis (1) certain rental income received in advance is
recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, (3) syndication costs are carried at their original value,
instead of being amortized over the estimated life of assets, and (4) income is
recorded at the partnership level based on the partnership agreement and the
Internal Revenue Code instead of being recorded based on the percentage of
ownership interest.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1996 include deferred loan costs of $131,024
which are amortized over the term of the related borrowing. Deferred costs are
shown net of accumulated amortization. Also included in other assets at December
31, 1996 are syndication costs of $194,045 which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1996 were $94,558 and consist of
a reserve escrow established with a portion of the proceeds of the loan. The
funds are used for certain repair work, debt service, expenses and property
taxes or insurance. The funds in the reserve escrow exceed the minimum balance
required to be maintained by the lender during the term of the loan.
 
NOTE C -- MORTGAGE NOTES PAYABLE
 
     Mortgage notes payable at December 31, 1996 consist of the following:

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
     The principal balance of the mortgage notes may not be prepaid, in whole or
in part, prior to October 15, 1996. Thereafter the principal may be prepaid in
whole upon payment of a penalty of the greater of one percent of the unpaid
principal balance at the time of payment or the present value of the excess of
interest which would be incurred at the stated rate under the notes over the
interest which would be incurred at the Treasury constant maturity for U.S.
Government obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the general partners for the
management and administration of all partnership activities. The Project
Partnership is obligated to pay a property management fee equal to 5% of gross
monthly collections. In addition to the management fee, the partnership
agreement provides for payments to general partners of a partnership
administration fee and reimbursement of certain expenses incurred by general
partners on behalf of the Partnership and the Project Partnership.
 
     Transactions with the General Partner and its affiliates are as follows:

Reimbursement for services to affiliates....................  $28,914
Construction fee............................................  $ 4,916
Reimbursement for oversight costs...........................  $17,784
</TABLE>
 
     The Partnership insures its properties under a master policy through an
agency and insurer unaffiliated with the General Partner. An affiliate of the
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the General Partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the General Partner by
virtue of the agent's obligations is not significant.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Baywood Partners, Limited:
 
     We have audited the consolidated statements of assets, liabilities and
partners' deficit -- income tax basis of Baywood Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1995 and
1994, and the related consolidated statements of revenues and expenses and
changes in partners' deficit -- income tax basis and cash flows -- income tax
basis for the years then ended. These consolidated financial statements are the
responsibility of the partnership's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting Baywood Partners, Limited uses for Federal
income tax purposes, which is a comprehensive basis of accounting other than
generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Baywood
Partners, Limited and its limited partnership interest as of December 31, 1995
and 1994, and the results of their operations and their cash flows for the years
then ended, on the basis of accounting described in Note A.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1995 AND 1994
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of Baywood
Partners, Limited (the "Partnership"), and its Limited Partnership interest in
Baywood Apartments (the "Project Partnership"). The Partnership was organized
solely to invest in the Project Partnership. The Project Partnership owns and
operates a 226 unit apartment complex located in Jefferson Parish, Louisiana.
 
     The Partnership was organized as an Alabama limited partnership on February
15, 1979. The General Partner of the Partnership is Angeles Properties, Inc.
("API"), which acts as a general partner in other limited partnerships and is an
affiliate of Angeles Investment Properties, Inc. ("AIPI"), the general partner
of the Project Partnership. Pursuant to the terms of the Agreement and Amended
Certificate of Limited Partnership (the "Agreement"), API has contributed
$100,000 to the Partnership for which it is entitled to a 1% operating interest
in the profits, losses, credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $1,936,200.
Pursuant to the terms of the Agreement, the limited partners will receive a 99%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership had made capital contributions of $1,442,000 to the Project
Partnership and is entitled to a 99% interest in the operating profits, losses,
credits and cash distributions of the Project Partnership. AIPI is entitled to
the remaining 1% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership's tax returns. The tax basis used differs from GAAP primarily
because on the tax basis (1) certain rental income received in advance is
recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, (3) syndication costs are carried at their original value,
instead of being amortized over the estimated life of assets, and (4) subsidiary
income is recorded at the partnership level based on the partnership agreement
and the Internal Revenue Code instead of being recorded based on the percentage
of ownership interest.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1995 and 1994 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization. Also included in other assets at December 31, 1995
and 1994 are $194,045 of syndication costs which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers cash and
all highly liquid investments, with an original maturity of three months or less
when purchased, to be cash and cash equivalents.
 
  Reclassifications
 
     Certain 1994 amounts have been reclassified to conform to the 1995
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1995 and 1994 consist of the
following:

NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the general partners for the
management and administration of all partnership activities. The Project
Partnership is obligated to pay a property management fee equal to 5% of gross

     The Partnership insures its properties under a master policy through an
agency and insurer unaffiliated with the General Partner. An affiliate of the
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the General Partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the General Partner by
virtue of the agent's obligations is not significant.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   378
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   379
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Brampton Associates Partnership. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   384
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   385
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $2,760.04 per unit for the six
     months ended June 30, 1998 (equivalent to $5,520.08 on an annualized
     basis.) We will pay fixed quarterly distributions of $               per
     unit on the Tax-Deferral   % Preferred OP Units before any distributions
     are paid to holders of Tax-Deferral Common OP Units. We pay quarterly
     distributions on the Tax-Deferral Common OP Units based on our funds from
     operations for that quarter. For the six months ended June 30, 1998, we
     paid distributions of $1.125 on each of the Tax-Deferral Common OP Units
     (equivalent to $2.25 on an annual basis). This is equivalent to
     distributions of $       per year on the number of Tax-Deferral   %
     Preferred OP Units or distributions of $            per year on the number
     of Tax-Deferral Common OP Units that you would receive in an exchange for
     each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income
 
                                       S-3
<PAGE>   386
 
     tax purposes, as a partial sale of such units for cash, and as a partial
     tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   387
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

Supplement and the accompanying Prospectus.

     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management

     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.

RISK FACTORS

beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   390
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   391
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   392
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   393
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   394
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least 66 2/3% of the units of your partnership.
     In the absence of such consent, your only option for liquidation of your
     investment would be to sell your units in a private transaction. Any such
     sale could be at a very substantial discount from your pro rata share of
     the fair market value of your partnership's property and might involve
     significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources. Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your
 
                                      S-12
<PAGE>   395
 
     partnership without the offer would deny you and your partners the benefits
     that your general partner expects to result from the offer. For example, a
     partner of your partnership would have no opportunity for liquidity unless
     he were to sell his units in a private transaction. Any such sale would
     likely be at a very substantial discount from the partner's pro rata share
     of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the

     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY

     BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR
TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN
THIS PROSPECTUS SUPPLEMENT AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO
STOCKHOLDERS," "FEDERAL INCOME TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND
OP UNITHOLDERS" AND "OTHER TAX CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND
CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO
YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

offering for each of your units, we divided the cash offer consideration by

Common Stock on the NYSE on a recent date before we commenced this offer.

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   400
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives such
compensation as is set forth in your partnership's agreement of limited
partnership or in other agreements executed between the general partner and your
partnership that are permitted by your partnership's agreement of limited
partnership and may also receive reimbursement for expenses generated in its
capacity as general partner of your partnership. The property manager received
management fees of $81,698 in 1996, $92,384 in 1997 and $46,023 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Brampton Associates Partnership is a
Connecticut limited partnership which was formed on December 31, 1985 for the
purpose of owning and operating a single apartment property located in Cary,
North Carolina, known as "Brampton Moors Apartments." In 1985, it completed a
 
                                      S-18
<PAGE>   401
 
private placement of units. Brampton Moors Apartments consists of 224 apartment
units. Your partnership has no employees.
 
     Property Management. Since December 1996, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2040, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $7,438,225, payable to First Union and
Lehman, which bears interest at a rate of 8.47%. The mortgage debt is due in
June 2004. Your partnership's agreement of limited partnership also allows your
general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, AIMCO was the largest owner and manager of multifamily
apartment properties in the United States with a total portfolio of 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. However, your general partner believes that the terms of our offer,
including the offer consideration, are fair to you. We have retained Stanger to
conduct an analysis of our offer and to render an opinion as to the fairness to
you of our cash offer consideration, from a financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   409
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   410
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $2,760.04 per unit (equivalent
to $5,520.08 on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   412
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 66 2/3% of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership may require funding from its partners. Continuation of
its operations may be dependent on additional funding from partners or from
other sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
                                      S-30
<PAGE>   413
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units. However, one
       class of outstanding Partnership Preferred Units has prior distribution
       rights and the Tax-Deferral   % Preferred OP Units rank equal to six
       other outstanding classes of Partnership Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   415
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   416
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   417
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   418
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   419
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   420
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

Partnership shall not be required to accept for payment and pay for any units

     including any fire, flood, natural disaster, casualty loss, or act of God

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If AIMCO Operating
Partnership acquires units in the offer, AIMCO will increase its ability to
influence voting decisions with respect to your partnership. Furthermore, in the
event that the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, removal of the general partner of your partnership
(which general partner is controlled by AIMCO) without AIMCO's consent may
become more difficult or impossible. AIMCO also owns the company that manages
your partnership's property. In the event that the AIMCO Operating Partnership
acquires a substantial number of units pursuant to the offer, removal of the
property manager may become more difficult or impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   423
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   425
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   426
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   427
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   428
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate

sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             its affiliates may purchase or acquire shares of Class

                                                             of Class I Preferred Stock. The redemption price for
                                                             the Class I Preferred Stock (other than any portion

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   433
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   434
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   436
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   437
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $2,760.04 (equivalent to $5,520.08
     on an annualized basis). This is equivalent to distributions of $
     per year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units, that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   438
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives such
compensation as is set forth in your partnership's agreement of limited
partnership or in other agreements executed between the general partner and your
partnership that are permitted by your partnership's agreement of limited
partnership from your partnership and may receive reimbursement for expenses
generated in that capacity. The property manager which received management fees
of $     in 1996, $     in 1997 and 46,023 for the first six months of 1998. The
AIMCO Operating Partnership has no current intention of changing the fee
structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Brampton Associates Partnership is a Connecticut limited partnership which
raised proceeds in 1985 through a private offering. Insignia acquired your
partnership in December 1996. AIMCO acquired Insignia in October, 1998. There
are currently a total of 53.875 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on December 31, 1985 for the purpose of owning
and operating a single apartment property located in Cary, North Carolina, known
as "Brampton Moors Apartments." Your partnership's property consists of 224
apartment units. There are 112 one-bedroom apartments and 112 two-bedroom
apartments. The total rentable square footage of your partnership's property is
187,600 square feet. Your partnership's property had an average occupancy rate
of approximately 89.29% in 1996 and 89.29% in 1997. The average annual rent per
apartment unit is approximately $7,878.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1996, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $81,698, $92,384 and $46,023, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2040
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement
 
                                      S-72
<PAGE>   455
 
     of various building systems and other replacements and renovations in the
ordinary course of business. All capital improvement and renovation costs are
expected to be paid from operating cash flows, cash reserves, or from short-term
or long-term borrowings. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $7,438,225, payable to First Union and Lehman, which bears
interest at a rate of 8.47%. The mortgage debt is due in June 2004. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

December 31, 1996, compared to a net loss of $161,509 for the year ended
December 31, 1995. The decrease in net income of $121,461, or 75.20% was
primarily the result of decreased revenues coupled with increased operating and
interest expenses. These factors are discussed in more detail in the following
paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,768,692 for the year ended December 31, 1996, compared to $1,780,701 for the
year ended December 31, 1995, a decrease of $12,009, or 0.67%.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $798,209 for the
year ended December 31, 1996, compared to $724,121 for the year ended December
31, 1995, an increase of $74,088 or 10.23%. The increase is primarily due to
increased advertising and maintenance expenses. Management expenses totaled
$89,291 for the year ended December 31, 1996, compared to $89,077 for the year
ended December 31, 1995, an increase of $214, or 0.24%.
 
     General and Administrative Expenses
 
     Not Applicable.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $767,081 for the year ended December 31, 1996, compared to
$744,746 for the year ended December 31, 1995, an increase of $22,335, or 3.00%.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $373,656 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on
 
                                      S-76
<PAGE>   459
 
     outstanding debt, capital improvements, and distributions paid to limited
partners. Your partnership has adequate sources of cash to finance its
operations, both on a short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner has no liability to your
partnership or to any partner for any loss suffered by your partnership or any
partner which arises out of any action or inaction of the general partner if the
general partner determines, in good faith, such course of conduct was in the
best interests of your partnership and such course of conduct did not constitute
negligence or misconduct of the general partner. As a result, unitholders might
have a more limited right of action in certain circumstances than they would
have in the absence of such a provision in your partnership's agreement of
limited partnership. The general partner of your partnership is owned by AIMCO.
See "Conflicts of Interest."
 
     Your partnership will indemnify the general partner and its affiliates
against any losses, judgments, liabilities, expenses and amounts paid in
settlement, sustained by it in connection with your partnership, provided that
the general partner determines that such course of conduct was in the best
interests of your partnership and that such course of conduct did not constitute
negligence or misconduct on the part of the general partner or its affiliates.
Notwithstanding the foregoing, the general partner and its affiliates, acting as
broker-dealers will not be indemnified for any losses, liabilities or expenses
arising under the Federal or states securities laws unless: (1) there has been a
successful adjudication on the merits of each count involving alleged securities
law violations, (2) such claims have been dismissed with prejudice on the merits
by a court of jurisdiction or (3) a court of competent jurisdiction approves a
settlement of claims. In such claim for indemnification for Federal or state
securities law violation, the party seeking indemnification must place before
the court the position of the SEC and any other applicable regulatory agency
with respect of the issue of indemnification for securities law violations. The
general partner or its affiliates will have advanced to them by your
partnership, at their request, funds for payment of all expenses and costs
reasonably incurred in connection with the defense of any action, suit or
proceeding only if (1) the legal action related to the performance of duties or
services by the general partner or its affiliates on behalf of your partnership,
(2) the legal action is initiated by a third party who is not a limited partner
of your partnership and (3) the general partner or its affiliates undertake to
repay the advanced funds to your partnership, without interest, if it is
determined that a general partner or its affiliates are not entitled to
indemnification. As part of its assumption of liabilities in the consolidation,
AIMCO will indemnify the general partner of your partnership and their
affiliates for periods prior to and following the consolidation to the extent of
the indemnity under the terms of your partnership's agreement of limited
partnership and applicable law.
 
     Your partnership will not incur the cost of that portion of any insurance,
other than public liability insurance, which insures any party against any
liability the indemnification of which is not permitted under your partnership's
agreement of limited partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner) was as follows:

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation and distributions that would have
been paid to the general partner of your partnership, or the company paid to the
property manager or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.

                  NOTES TO THE CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Brampton Associates,
L.P. as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with the accounting basis for federal income
tax reporting. Accordingly, they do not include all the information and
footnotes required by the accounting basis for federal income tax reporting for
complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

     We have reviewed the accompanying balance sheets of Brampton Associates,
L.P., income tax basis, as of December 31, 1997, and the related statements of
income and partners' capital (deficit), income tax basis, for the year then
ended, and statement of cash flow, income tax basis, for the year ending
December 31, 1997, in accordance with statements on standards for accounting and
review services issued by the American Institute of Certified Public
Accountants. All information included in these financial statements is the
representation of the management of Brampton Associates, L.P.
 
     A review consists principally of inquiries of company personnel and
analytical procedures applied to financial data. It is substantially less in
scope than an examination in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion regarding the
financial statements taken as a whole. Accordingly, we do not express such an
opinion.
 
     As described in Note 2, these financial statements were prepared on the
accounting basis used for income tax purposes and are not intended to be in
conformity with generally accepted accounting principles. As described in Note 6
and 8, we were unable to confirm the accrued interest receivable and the
Gaincred III note balance at December 31, 1997.
 
     Based on our review, we are not aware of any material modification that
should be made to the accompanying financial statements in order for them to be
in conformity with the basis of accounting described in Note 2.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE 1 --
 
  A. Organization
 
     Brampton Associates, L.P. (the "Partnership"), a Connecticut Limited
Partnership, was organized on December 17, 1985 to acquire, own, maintain and
operate a 224 unit apartment complex known as Brampton Moors (the "Project")
located in Cary, North Carolina.
 
  B. Purchase by RFC
 
     Pursuant to an acquisition agreement dated October 9, 1985, Resources
Funding Corp. ("RFC"), an affiliate of the former general partner, agreed to
acquire from Westminster Company (the "Seller") the land and the completed
improvements for an aggregate purchase price of $10,000,000 with $1,400,000
allocable to the land and $8,600,000 (which was subsequently reduced by $600,000
to $8,000,000 pursuant to a predetermined pricing formula) allocable to the
improvements. The portion allocable to the improvements is inclusive of interest
at the rate of 16% per annum on certain deferred payments.
 
     On December 31, 1985, the Partnership purchased the land for $1,400,000 and
simultaneously entered into a one year lease agreement with the Seller which
required the Seller to complete the construction of the improvements and to pay
$168,000 per annum in rent to the Partnership. Upon completion of the
improvements in December 1986, RFC paid $7,300,000 (the "Interim Payment") to
the Seller with the balance of $1,300,000 (the "Deferred Payment") payable upon
the occurrence of certain events. $700,000 of the Deferred Payment was paid to
the Seller on the first anniversary of the Interim Payment. The remaining
$600,000 balance of purchase price was not earned by the Seller as the project
did not attain certain predetermined performance levels, thus reducing the
purchase price. The benefit of such reduction in the purchase price was passed
on to the partnership by RFC.
 
  C. Purchase from RFC
 
     Pursuant to the terms of an assignment and assumption agreement dated
December 27, 1985, and a purchase agreement, the Partnership acquired the rights
of RFC under the acquisition agreement. The original purchase price (the
"Purchase Price") payable to RFC by the Partnership for such rights was
$4,080,763, which was reduced to $3,480,763 because of the adjustment to the
Purchase Price paid by RFC to the Seller (see Note 1B).
 
     The Partnership's obligation to pay the Purchase Price is non-recourse to
the general partner and limited partners of the Partnership. A portion of the
Purchase Price was paid with the proceeds of the Partnership borrowing from
Gaincred III Corp. (see Note 8). The limited partners' notes, together with the
collateral securing such notes (including the Project), are pledged to RFC to
secure payment of the Purchase Price or to Gaincred III Corp. to secure payment
of borrowing by the Partnership (see Note 6). On May 7, 1997, the Partnership
refinanced the property (see Note 7) and satisfied the note to RFC.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The financial statements of the Partnership are prepared on the accrual
basis of accounting, consistent with reporting for federal income tax purposes,
and include only those assets, liabilities, and results of operations of the
partnership, rather than those of the individual partners.
 
     The building and equipment are stated at cost and are being depreciated
using the accelerated cost recovery system ("ACRS") for assets placed in service
prior to January 1, 1987 and the modified accelerated cost recovery system
("MACRS") for assets placed in service after December 31, 1986.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Costs incurred in connection with the sale of the limited partnership units
were capitalized and are not being amortized.
 
     The income or loss of the Partnership is allocated 1% to the general
partner and 99% to the limited partners. There is no provision for income taxes
in the financial statements since the income or loss of the Partnership is
required to be reported by the partners on their respective income tax returns.
 
NOTE 3 -- CASH AND CASH EQUIVALENTS
 
     For purposes of the statement of cash flow, the Partnership considers all
highly liquid investment instruments with a maturity of three months or less to
be cash equivalents.
 
NOTE 4 -- PROPERTY, EQUIPMENT AND DEPRECIATION
 
     Depreciation is recorded at rates calculated to amortize the cost of the
assets as follows:

     Land, building, and equipment, with a cost of $10,262,811 are pledged as
collateral for the mortgage note payable.
 
     The costs of maintenance and repairs of the property and equipment are
charged to expense as incurred.

     Deferred expenses and the related amortization are set forth as follows:

</TABLE>
 
     The Partnership refinanced the mortgage on May 7, 1997, consequently, the
unamortized cost of acquiring the previous mortgage has been fully amortized in
1997. Syndication costs are a nondeductible expense and therefore are not being
amortized.
 
NOTE 6 -- NOTES RECEIVABLE (PARTNERS' CAPITAL CONTRIBUTIONS)
 
     The notes receivable represent capital contributions from the limited
partners. They are payable in quarterly installments of principal and interest
over either a four year or a seven year payment schedule, as elected by each
partner. The notes are unconditional and negotiable and bear interest at the
rate of 11.5% per annum. Interest has not been accrued on these notes for the
current year due to the transition of the general partners and the lack of
sufficient data available from the former general partner. Integrated Resources,
Inc. experienced serious financial difficulties and on February 13, 1990 filed a
voluntary petition for reorganization pursuant to the provisions of Chapter 11.
Notes receivable have been pledged as collateral to secure the Partnership
obligation of the Purchase Price payable to RFC and the note payable to Gaincred
III Corp. (See Notes 1C, 8, 9, and 10).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 7 -- MORTGAGE NOTES PAYABLE
 
     The Project was subject to a mortgage held by Legg Mason Real Estate
Service Inc. ("Mortgagee") in the original principal amount of $6,400,000. The
mortgage required monthly installments of $62,507 (based on a 35 year
amortization schedule), including interest at the rate of 11.5% per annum. The
mortgage matured on December 1, 1996.
 
     On May 7, 1997, the Partnership refinanced the property with Lehman
Brothers Holdings Inc., which subsequently sold the mortgage to First Union
National Bank of North Carolina. The proceeds of the mortgage were used to
satisfy the first and second mortgage as well as the note with Resources Funding
Corp ("RFC"). The Partnership borrowed $7,500,000.00 at 8.47% per annum. On June
1, 1997 the Partnership was required to pay a payment of interest only with a
constant payment of $57,509.13 commencing on July 1, 1997 and on the first day
of each calendar month thereafter to and including the first day of May, 2004.
The balance of the principal sum then outstanding and all the interest thereon
shall be due and payable on the first day of June, 2004. The Partnership shall
not have the privilege or right to prepay all or any portion of the unpaid
principal balance of the note until May 31, 2001.
 
     Land, building and equipment are pledged as collateral for the above
mortgage.
 
NOTE 8 -- NOTE PAYABLE -- GAINCRED III CORP.
 
     On December 22, 1988, the Partnership borrowed $1,069,925 from Gaincred III
Corp. evidenced by a single limited recourse promissory note. The note bears
interest at 12% per annum and is payable from the collections of certain limited
partners' notes as specified in the agreement. The proceeds of the borrowing
were used to paydown the Purchase Price (see note 1C). The sole security for
this obligation is certain limited partners notes and their limited partnership
interests. The balance of the note as of December 31, 1997 was unable to be
confirmed. However, since the partners notes are the only security for this
note, it has an immaterial effect on the financial statements taken as a whole.
 
NOTE 9 -- PURCHASE PRICE AND INTEREST ON PURCHASE PRICE PAYABLE
 
     This amount represented the unpaid balance of the purchase price payable to
RFC. On May 7, 1997 the balance of the note, along with the accrued interest was
satisfied with the proceeds of the refinancing with Lehman Brothers Holdings,
Inc. The obligation carried interest from December 31, 1985 at the rate of 14%
per annum prior to the Reorganization Plan and 9.5% per annum pursuant to the
Reorganization Plan, compounded quarterly (see note 1C).
 
NOTE 10 -- MANAGEMENT FEE
 
The Partnership entered into a management contract with Resources Property
Management Corp. ("RPMC"), an affiliate of the general partner. The contract
called for a fee of 4% of the gross receipts, as defined in the contract. The
management contract with RPMC was terminated effective June 1, 1991. A new
management contract was entered into by the Partnership with Drucker & Falk
effective June 1, 1991 on similar terms as with RPMC. This contract was
terminated effective November 1, 1993. Upon termination of their contract the
Partnership owed RPMC $45,169 for their services. However, pursuant to the
Reorganization Plan, the amount due to RPMC was reduced to $10,000 which was
paid in 1993. On November 1, 1993, a management contract was entered into with
NPI Property Management Corp. and in February 1996, Insignia Financial became
the new management company. Management fees paid to Insignia Financial for 1997
were $92,384.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 11 -- PETITION FOR RELIEF UNDER CHAPTER 11
 
     On December 18, 1991, the Partnership filed petitions for relief under
Chapter 11 of the United States Bankruptcy Code in the Federal Bankruptcy Court
for the Southern District of New York. The Reorganization Plan developed by the
Partnership was confirmed by the Federal Bankruptcy Court for the Southern
District of New York on September 15, 1992, effective September 30, 1992. Under
the Reorganization Plan, certain debts of the Partnership were reduced and the
terms of repayment modified as described in Notes 9, 10, and 11. In accordance
with the Internal Revenue Code, the reduction of the Purchase Price payable, as
described in Note 9 was applied to reduce the basis of the fixed assets, and the
reduction of the amounts due to Integrated and its affiliates (Note 11) and RPMC
(Note 10) which was recorded as cancellation of debt income in the 1992
financial statements.

     We have reviewed the accompanying balance sheets of Brampton Associates,
L.P., income tax basis, as of December 31, 1996, and the related statements of
income and partners' capital (deficit), income tax basis, for the year then
ended, and statement of cash flow, income tax basis, for the year ending
December 31, 1996, in accordance with statements on standards for accounting and
review services issued by the American Institute of Certified Public
Accountants. All information included in these financial statements is the
representation of the management of Brampton Associates, L.P.
 
     A review consists principally of inquiries of company personnel and
analytical procedures applied to financial data. It is substantially less in
scope than an examination in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion regarding the
financial statements taken as a whole. Accordingly, we do not express such an
opinion.
 
     As described in Note 2, these financial statements were prepared on the
accounting basis used for income tax purposes and are not intended to be in
conformity with generally accepted accounting principles. As described in Note 6
and 8, we were unable to confirm the accrued interest receivable and the
Gaincred III Note Balance at December 31, 1996.
 
     Based on our review, we are not aware of any material modification that
should be made to the accompanying financial statements in order for them to be
in conformity with the basis of accounting described in Note 2.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
NOTE 1 --
  A. Organization
 
     Brampton Associates, L.P. (the "Partnership"), a Connecticut limited
partnership, was organized on December 17, 1985 to acquire, own, maintain and
operate a 224 unit apartment complex known as Brampton Moors (the "Project")
located in Cary, North Carolina.
 
  B. Purchase by RFC
 
     Pursuant to an acquisition agreement dated October 9, 1985, Resources
Funding Corp. ("RFC"), an affiliate of the former general partner, agreed to
acquire from Westminster Company (the "Seller") the land and the completed
improvements for an aggregate purchase price of $10,000,000 with $1,400,000
allocable to the land and $8,600,000 (which was subsequently reduced by $600,000
to $8,000,000 pursuant to a predetermined pricing formula) allocable to the
improvements. The portion allocable to the improvements is inclusive of interest
at the rate of 16% per annum on certain deferred payments.
 
     On December 31, 1985, the partnership purchased the land for $1,400,000 and
simultaneously entered into a one year lease agreement with the seller which
required the seller to complete the construction of the improvements and to pay
$168,000 per annum in rent to the partnership. Upon completion of the
improvements in December 1986, RFC paid $7,300,000 (the "Interim Payment") to
the seller with the balance of $1,300,000 (the "Deferred Payment") payable upon
the occurrence of certain events. $700,000 of the deferred payment was paid to
the seller on the first anniversary of the interim payment. The remaining
$600,000 balance of purchase price was not earned by the seller as the project
did not attain certain predetermined performance levels, thus reducing the
purchase price. The benefit of such reduction in the purchase price was passed
on to the partnership by RFC.
 
  C. Purchase from RFC
 
     Pursuant to the terms of an assignment and assumption agreement dated
December 27, 1985, and a purchase agreement, the partnership acquired the rights
of RFC under the acquisition agreement. The original purchase price (the
"Purchase Price") payable to RFC by the partnership for such rights was
$4,080,763, which was reduced to $3,480,763 because of the adjustment to the
purchase price paid by RFC to the seller (see Note 1B).
 
     The partnership's obligation to pay the purchase price is non-recourse to
the general partner and limited partners of the partnership. A portion of the
purchase price was paid with the proceeds of the partnership borrowing from
Gaincred III Corp (see Note 8). The limited partners' notes, together with the
collateral securing such notes (including the project), are pledged to RFC to
secure payment of the purchase price or to Gaincred III Corp to secure payment
of borrowing by the partnership (see Note 6).
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The financial statements of the partnership are prepared on the accrual
basis of accounting, consistent with reporting for federal income tax purposes,
and include only those assets, liabilities, and results of operations of the
partnership, rather than those of the individual partners.
 
     The building and equipment are stated at cost and are being depreciated
using the Accelerated Cost Recovery System ("ACRS") for assets placed in service
prior to January 1, 1987 and the modified Accelerated Cost Recovery System
("MACRS") for assets placed in service after December 31, 1986.
 
     Costs incurred in connection with the sale of the limited partnership units
were capitalized and are not being amortized.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The income or loss of the partnership is allocated 1% to the general
partner and 99% to the limited partners. There is no provision for income taxes
in the financial statements since the income or loss of the partnership is
required to be reported by the partners on their respective income tax returns.
 
NOTE 3 -- CASH AND CASH EQUIVALENTS
 
     For purposes of the statement of cash flow, the partnership considers all
highly liquid investment instruments with a maturity of three months or less to
be cash equivalents.
 
NOTE 4 -- PROPERTY, EQUIPMENT AND DEPRECIATION
 
     Depreciation is recorded at rates calculated to amortize the cost of the
assets as follows:

     In addition, during 1996, legal fees of $10,475 and financing fees of
$16,175 were paid as part of the refinancing as discussed in Note 7. These fees
have not been subject to amortization until the refinancing is finalized.
Syndication costs are a nondeductable expense and therefore are not being
amortized.
 
NOTE 6 -- NOTES RECEIVABLE (PARTNERS' CAPITAL CONTRIBUTIONS)
 
     The notes receivable represent capital contributions from the limited
partners. They are payable in quarterly installments of principal and interest
over either a four year or a seven year payment schedule, as elected by each
partner. The notes are unconditional and negotiable and bear interest at the
rate of 11.5% per annum. Interest has not been accrued on these notes for the
current year due to the transition of the general partners and the lack of
sufficient data available from the former general partner. Integrated Resources,
Inc. experienced serious financial difficulties and on February 13, 1990 filed a
voluntary petition for reorganization pursuant to the provisions of Chapter 11.
Notes receivable have been pledged as collateral to secure the partnership
obligation of the purchase price payable to RFC and the note payable to Gaincred
III Corp. (See Notes 1C, 8, 9, and 10).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 7 -- MORTGAGE NOTES PAYABLE
 
     The project was subject to a mortgage held by Legg Mason Real Estate
Service Inc. ("Mortgagee") in the original principal amount of $6,400,000. The
mortgage required monthly installments of $62,507 (based on a 35 year
amortization schedule), including interest at the rate of 11.5% per annum. The
mortgage matured on December 1, 1996. The partnership is presently negotiating
refinancing with Lehman Brothers. Lehman Brothers is purchasing the mortgage
payable to both Legg Mason and Key Bank Society National Bank.
 
     As a condition to financing, the partnership was required to supply a
letter of credit or to place up to $2 million in escrow, the amount of such
funds to decline based on the amount of the shortfall from predetermined
property performance levels. If two years from the date of disbursement of the
mortgage loan, the project had not yet achieved the predetermined property
performance levels, the mortgage loan would be reduced by 95% of the amount then
held in escrow drawn under the letter of credit (the remaining 5% to be paid to
the lender as a reinvestment fee). RFC had agreed to advance to the partnership
the required letter of credit or escrow amount and in the event of a reduction
in the mortgage loan and payment of a reinvestment fee to the lender, RFC has
agreed to lend the total of such amounts to the partnership on the same
conditions as such amounts would have been due under the mortgage loan. However,
the partnership, and not RFC, posted the letter of credit. The partnership also
posted its demand note as security for nay drawings under the letter of credit
and Integrated Resources, Inc. guaranteed the obligation of the partnership in
connection with the letter of credit. In 1988, as a result of meeting certain
predetermined property performance levels, the amount of the letter of credit
was reduced to $500,000.
 
     As a result of the project not meeting certain predetermined performance
levels, on February 15, 1990, the escrow agent for the holder of the permanent
mortgage drew the entire amount of $500,000. Available under the letter of
credit. 95% of the drawn amount was applied towards the reduction of principal
of the mortgage loan and the remaining 5% of the drawn down amount was paid to
Crown Life Insurance Company, the former mortgagee, as a reinvestment fee. Due
to a reduction of the remaining principal balance, the mortgagee agreed to
reduce the monthly installment payments from $62,507 to $57,835 effective April
1, 1990. The mortgage note can be prepaid in full at a premium as described in
the mortgage note.
 
     As a result of a drawdown under the letter of credit as described above,
the demand note in the amount of $500,000 became payable to Society National
Bank ("Society"), (formerly Ameritrust Company National Associates) on February
15, 1990. Pursuant to a plan of reorganization approved by the bankruptcy court
under Chapter 11 of the United States Bankruptcy Code ("Reorganization Plan"),
the demand note due to Society was converted into a term loan in the amount of
$500,000 (the "Second Mortgage"). The second mortgage required monthly payments
of $4,491 (based on a 35 year amortization schedule), including interest at the
rate of 10.5% per annum and matured on December 1, 1996. The Society Mortgage
was part of the refinancing plan as discussed above.
 
     Land, building and equipment, carried at a net book value of $4,541,896 are
pledged as collateral for the above mortgages as well as the refinancing
mortgage.
 
NOTE 8 -- NOTE PAYABLE -- GAINCRED III CORP.
 
     On December 22, 1988, the partnership borrowed $1,069,925 form Gaincred III
Corp. evidenced by a single limited recourse promissory note. The note bears
interest at 12% per annum and is payable from the collections of certain limited
partners' notes as specified in the agreement. The proceeds of the borrowing
were used to paydown the purchase price (see Note 1C). The sole security for
this obligation is certain limited partners notes and their limited partnership
interests. The balance of the note as of December 31, 1996 was unable to be
confirmed during this period of transition. However, since the partners notes
are the only security for this note, it has an immaterial effect on the
financial statements taken as a whole.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 9 -- PURCHASE PRICE AND INTEREST ON PURCHASE PRICE PAYABLE
 
     This amount represents the unpaid balance of the purchase price payable to
RFC. The obligation carried interest from December 31, 1985 at the rate of 14%
per annum, compounded quarterly (see Note 1C). Pursuant to the reorganization
plan, the unpaid balance of the purchase price was reduced by $194,000. The new
RFC note with a current principal amount of $787,529 bears interest at 9.5% per
annum and is secured by certain notes from limited partners (see Note 1C).
Subject to certain restrictions, the new RFC note is to be paid from the
proceeds of collection of the notes receivable from limited partners, cash flows
from operations of the project and from sales proceeds of the project. The
partnership has incurred default interest in the amount of $30,500 which shall
bear interest at the rate of 9.5% per annum and shall be payable on December 1,
1997. This default amount will be waived if no future events of default occur.
This interest is not included in the financial statements due to its contingency
on future events.
 
NOTE 10 -- MANAGEMENT FEE
 
     The partnership entered into a management contract with Resources Property
Management Corp. ("RPMC"), an affiliate of the general partner. The contract
called for a fee of 4% of the gross receipts, as defined in the contract. The
management contract with RPMC was terminated effective June 1, 1991. A new
management contract was entered into by the partnership with Drucker & Falk
effective June 1, 1991 on similar terms as with RPMC. This contract was
terminated effective November 1, 1993. Upon termination of their contract the
partnership owed RPMC $45,169 for their services. However, pursuant to the
reorganization plan, the amount due to RPMC was reduced to $10,000 which was
paid in 1993. On November 1, 1993, a new management contract was entered into
with NPI Property Management Corp. which was an affiliate of the new general
partner. Management fees paid to NPI Property Management Corp. for the year
ended December 31, 1996 are $7,593.00. In February 1996, Insignia Financial
became the new management company. Management fees paid to Insignia Financial
for 1996 were $81,698.00.
 
NOTE 11 -- PETITION FOR RELIEF UNDER CHAPTER 11
 
     On December 18, 1991, the partnership filed petitions for relief under
Chapter 11 of the United States Bankruptcy Code in the Federal Bankruptcy Court
for the Southern District of New York. The Reorganization Plan developed by the
partnership was confirmed by the Federal Bankruptcy Court for the Southern
District of New York on September 15, 1992, effective September 30, 1992. Under
the Reorganization Plan, certain debts of the partnership were reduced and the
terms of repayment modified as described in Notes 9, 10, and 11. In accordance
with the Internal Revenue Code, the reduction of the purchase price payable, as
described in Note 9 was applied to reduce the basis of the fixed assets, and the
reduction of the amounts due to Integrated and its affiliates (Note 11) and RPMC
(Note 10) which was recorded as cancellation of debt income in the 1992
financial statements.

     We have reviewed the accompanying balance sheets of Brampton Associates,
L.P., income tax basis, as of December 31, 1995, and the related statements of
income and partners' capital (deficit), income tax basis, for the year then
ended, and statement of cash flow, income tax basis, for the year ending
December 31, 1995, in accordance with statements on standards for accounting and
review services issued by the American Institute of Certified Public
Accountants. All information included in these financial statements is the
representation of the management of Brampton Associates, L.P.
 
     A review consists principally of inquiries of company personnel and
analytical procedures applied to financial data. It is substantially less in
scope than an examination in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion regarding the
financial statements taken as a whole. Accordingly, we do not express such an
opinion.
 
     As described in Note 2, these financial statements were prepared on the
accounting basis used for income tax purposes and are not intended to be in
conformity with generally accepted accounting principles. As described in Note 6
and 8, we were unable to confirm the accrued interest receivable and the
Gaincred III note balance at December 31, 1995.
 
     Based on our review, we are not aware of any material modification that
should be made to the accompanying financial statements in order for them to be
in conformity with the basis of accounting described in Note 2.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
NOTE 1 --
  A. Organization
 
     Brampton Associates, L.P. (the "Partnership"), a Connecticut Limited
Partnership, was organized on December 17, 1985 to acquire, own, maintain and
operate a 224 unit apartment complex known as Brampton Moors (the "Project")
located in Cary, North Carolina.
 
  B. Purchase by RFC
 
     Pursuant to an acquisition agreement dated October 9, 1985, Resources
Funding Corp. ("RFC"), an affiliate of the former general partner, agreed to
acquire from Westminster Company (the "Seller") the land and the completed
improvements for an aggregate purchase price of $10,000,000 with $1,400,000
allocable to the land and $8,600,000 (which was subsequently reduced by $600,000
to $8,000,000 pursuant to a predetermined pricing formula) allocable to the
improvements. The portion allocable to the improvements is inclusive of interest
at the rate of 16% per annum on certain deferred payments.
 
     On December 31, 1985, the Partnership purchased the land for $1,400,000 and
simultaneously entered into a one year lease agreement with the Seller which
required the Seller to complete the construction of the improvements and to pay
$168,000 per annum in rent to the Partnership. Upon completion of the
improvements in December 1986, RFC paid $7,300,000 (the "Interim Payment") to
the Seller with the balance of $1,300,000 (the "Deferred Payment") payable upon
the occurrence of certain events. $700,000 of the Deferred Payment was paid to
the Seller on the first anniversary of the Interim Payment. The remaining
$600,000 balance of purchase price was not earned by the Seller as the project
did not attain certain predetermined performance levels, thus reducing the
purchase price. The benefit of such reduction in the purchase price was passed
on to the Partnership by RFC.
 
  C. Purchase from RFC
 
     Pursuant to the terms of an assignment and assumption agreement dated
December 27, 1985, and a purchase agreement, the Partnership acquired the rights
of RFC under the acquisition agreement. The original purchase price (the
"Purchase Price") payable to RFC by the Partnership for such rights was
$4,080,763, which was reduced to $3,480,763 because of the adjustment to the
purchase price paid by RFC to the Seller (see Note 1B).
 
     The Partnership's obligation to pay the Purchase Price is non-recourse to
the general partner and limited partners of the Partnership. A portion of the
purchase price was paid with the proceeds of the Partnership borrowing from
Gaincred III Corp (see Note 8). The limited partners' notes, together with the
collateral securing such notes (including the Project), are pledged to RFC to
secure payment of the Purchase Price or to Gaincred III Corp to secure payment
of borrowing by the Partnership (see Note 6).
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The financial statements of the Partnership are prepared on the accrual
basis of accounting, consistent with reporting for federal income tax purposes,
and include only those assets, liabilities, and results of operations of the
Partnership, rather than those of the individual partners.
 
     The building and equipment are stated at cost and are being depreciated
using the Accelerated Cost Recovery System ("ACRS") for assets placed in service
prior to January 1, 1987 and the Modified Accelerated Cost Recovery System
("MACRS") for assets placed in service after December 31, 1986.
 
     Costs incurred in connection with the sale of the limited partnership units
were capitalized and are not being amortized.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The income or loss of the Partnership is allocated 1% to the general
partner and 99% to the limited partners. There is no provision for income taxes
in the financial statements since the income or loss of the Partnership is
required to be reported by the partners on their respective income tax returns.
 
NOTE 3 -- CASH AND CASH EQUIVALENTS
 
     For purposes of the statement of cash flow, the Partnership considers all
highly liquid investments with a maturity of three months or less to be cash
equivalents.
 
NOTE 4 -- PROPERTY, EQUIPMENT AND DEPRECIATION
 
     Depreciation is recorded at rates calculated to amortize the cost of the
assets as follows:

     Syndication costs are a nondeductable expense and therefore are not being
amortized.
 
NOTE 6 -- NOTES RECEIVABLE (PARTNERS' CAPITAL CONTRIBUTIONS)
 
     The notes receivable represent capital contributions from the limited
partners. They are payable in quarterly installments of principal and interest
over either a four year or a seven year payment schedule, as elected by each
partner. The notes are unconditional and negotiable and bear interest at the
rate of 11.5% per annum. Interest has not been accrued on these notes for the
current year due to the transition of the general partners and the lack of
sufficient data available from the former general partner. Integrated Resources,
Inc. experienced serious financial difficulties and on February 13, 1990 filed a
voluntary petition for reorganization pursuant to the provisions of Chapter 11.
Notes receivable have been pledged as collateral to secure the Partnership
obligation of the Purchase Price payable to RFC and the note payable to Gaincred
III Corp. (See Notes 1C, 8, 9, and 10).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 7 -- MORTGAGE NOTES PAYABLE
 
     The project is subject to a mortgage held by Legg Mason Real Estate Service
Inc. ("Mortgagee") in the original principal amount of $6,400,000. The mortgage
required monthly installments of $62,507 (based on a 35 year amortization
schedule), including interest at the rate of 11.5% per annum. The mortgage
matures on December 1, 1996, therefore the remaining principal balance is
classified as current liability in the financial statements.
 
     As a condition to financing, the Partnership was required to supply a
letter of credit or to place up to $2 million in escrow, the amount of such
funds to decline based on the amount of the shortfall from predetermined
property performance levels. If two years from the date of disbursement of the
mortgage loan, the project had not yet achieved the predetermined property
performance levels, the mortgage loan would be reduced by 95% of the amount then
held in escrow drawn under the letter of credit (the remaining 5% to be paid to
the lender as a reinvestment fee). RFC had agreed to advance to the Partnership
the required letter of credit or escrow amount and in the event of a reduction
in the mortgage loan and payment of a reinvestment fee to the lender, RFC has
agreed to lend the total of such amounts to the Partnership on the same
conditions as such amounts would have been due under the mortgage loan. However,
the Partnership, and not RFC, posted the letter of credit. The Partnership also
posed its demand note as security for any drawings under the letter of credit
and Integrated Resources, Inc. guaranteed the obligation of the Partnership in
connection with the letter of credit. In 1988, as a result of meeting certain
predetermined property performance levels, the amount of the letter of credit
was reduced to $500,000.
 
     As a result of the project not meeting certain predetermined performance
levels, on February 15, 1990, the escrow agent for the holder of the permanent
mortgage drew the entire amount of $500,000, available under the letter of
credit. 95% of the drawn amount was applied towards the reduction of principal
of the mortgage loan and the remaining 5% of the drawn down amount was paid to
Crown Life Insurance Company, the former Mortgagee, as a reinvestment fee. Due
to a reduction of the remaining principal balance, the Mortgagee agreed to
reduce the monthly installment payments from $62,507 to $57,835 effective April
1, 1990. Interest aggregating $662,606 was paid during the year under this
mortgage note. The mortgage note can be prepaid in full at a premium as
described in the mortgage note.
 
     As a result of a drawdown under the letter of credit as described above,
the demand note in the amount of $500,000 became payable to Society National
Bank ("Society"), (formerly Ameritrust Company National Associates) on February
15, 1990. Pursuant to a plan of reorganization approved by the Bankruptcy Court
under Chapter 11 of the United States Bankruptcy Code ("Reorganization Plan"),
the demand note due to Society was converted into a term loan in the amount of
$500,000 (the "Second Mortgage"). The Second Mortgage requires monthly payments
of $4,491 (based on a 35 year amortization schedule), including interest at the
rate of 10.5% per annum and will mature on December 1, 1996. Interest in the
amount of $49,275 was paid on the demand note payable to Society.
 
     Land, building and equipment, carried at a net book value of $4,831,198 are
pledged as collateral for the above mortgages.
 
NOTE 8 -- NOTE PAYABLE -- GAINCRED III CORP.
 
     On December 22, 1998, the Partnership borrowed $1,069,925 from Gaincred III
Corp. evidenced by a single limited recourse promissory note. The note bears
interest at 12% per annum and is payable from the collections of certain limited
partners' notes as specified in the agreement. The proceeds of the borrowing
were used to paydown the Purchase Price (see Note 1C). The sole security for
this obligation is certain limited partners notes and their limited partnership
interests. The balance of the note as of December 31, 1995 was unable to be
confirmed during this period of transition. However, since the partners notes
are the only security for this note, it has an immaterial effect on the
financial statements taken as a whole.

NOTE 9 -- PURCHASE PRICE AND INTEREST ON PURCHASE PRICE PAYABLE
 
     This amount represents the unpaid balance of the Purchase Price payable to
RFC. The obligation carried interest from December 31, 1985 at the rate of 14%
per annum, compounded quarterly (see Note 1C). Pursuant to the Reorganization
Plan, the unpaid balance of the Purchase Price was reduced by $194,000. The new
RFC note with a principal amount of $989,932 bears interest at 9.5% per annum
and is secured by certain notes from limited partners (see Note 1C). Subject to
certain restrictions, the new RFC note is to be paid from the proceeds of
collection of the notes receivable from limited partners, cash flows from
operations of the Project and from sales proceeds of the Project. The
Partnership has incurred default interest in the amount of $30,500 which shall
bear interest at the rate of 9.5% per annum and shall be payable on December 1,
1997. This default amount will be waived if no future events of default occur.
This interest is not included in the financial statements due to its contingency
on future events.
 
NOTE 10 -- RESTRICTED CASH
 
     The restricted cash represented collections of notes receivable held in a
separate bank account subject to certain restrictions. This cash was used to
reduce the new RFC note (see Note 9) by $108,253 in principal and to pay the
interest accrued through August 7, 1995 of $131,213. In addition, $71,314 was
paid to reduce the Society National Bank Demand Note (see Note 7).
 
NOTE 11 -- MANAGEMENT FEE
 
     The Partnership entered into a management contract with Resources Property
Management Corp. ("RPMC"), an affiliate of the general partner. The contract
called for a fee of 4% of the gross receipts, as defined in the contract. The
management contract with RPMC was terminated effective June 1, 1991. A new
management contract was entered into by the Partnership with Drucker & Falk
effective June 1, 1991 on similar terms as with RPMC. This contract was
terminated effective November 1, 1993. Upon termination of their contract the
Partnership owed RPMC $45,169 for their services. However, pursuant to the
Reorganization Plan, the amount due to RPMC was reduced to $10,000 which was
paid in 1993. On November 1, a new management contract was entered into with NPI
Property Management Corp. which is an affiliate of the new general partner.
Management fees paid to NPI Property Management Corp. for the year ended
December 31, 1995 are $89,077.00.
 
NOTE 12 -- PETITION FOR RELIEF UNDER CHAPTER 11
 
     On December 18, 1991, the Partnership filed petitions for relief under
Chapter 11 of the United States Bankruptcy Code in the Federal Bankruptcy Court
for the Southern District of New York. The Reorganization Plan developed by the
Partnership was confirmed by the Federal Bankruptcy Court for the Southern
District of New York, on September 15, 1992, effective September 30, 1992. Under
the Reorganization Plan, certain debts of the Partnership were reduced and the
terms of repayment modified as described in Notes 9, 10 and 11. In accordance
with the Internal Revenue Code, the reduction of the Purchase Price payable, as
described in Note 9 was applied to reduce the basis of the fixed assets, and the
reduction of the amounts due to Integrated and its affiliates (Note 11) and RPMC
(Note 10) which was recorded as cancellation of debt income in the 1992
financial statements.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   501
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   502
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Buccaneer Trace Limited Partnership. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49   states, the District of Columbia and
     Puerto Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million,
     total debt of $1,314 million and stockholders' equity of $1,394 million. On
     a pro forma basis, giving effect to our recently completed merger with
     Insignia Financial Group, Inc. and related transactions, as of June 30,
     1998, AIMCO had total assets of $3,972 million, total debt of $1,626
     million and stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   507
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   508
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0 per unit for the six months ended
     June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   509
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   510
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   513
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   514
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   515
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   516
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   517
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   518
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %
Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If

to time (the "Letter of Transmittal"). To be eligible to receive Tax-Deferral
     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an

limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant

amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated

actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making

jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We

securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
 
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions, liquidity and
transfer and redemption rights. See "Comparison of Preferred OP Units and Class
I Preferred Stock" for a chart highlighting such differences.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In addition, we considered the recent decline in the market for equity
securities, including, those of REITS, and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely-accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the
 
                                      S-17
<PAGE>   523
 
fairness opinion. Based on its analysis, and subject to the assumptions,
limitations and qualifications cited in its opinion, Stanger concluded that our
offer consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 1/2 of
1% of the gross operating revenue of your partnership's property as a
partnership administration fee from your partnership and may receive
reimbursement for expenses generated in that capacity. The property manager
which received management fees of $74,140 in 1996, $79,405 in 1997 and $34,705
for the first six months of 1998. We have no current intention of changing the
fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. Buccaneer Trace Limited Partnership is a
South Carolina limited partnership which was formed on October 31, 1985 for the
purpose of owning and operating a single apartment property located in Savannah,
Georgia, known as "Buccaneer Trace Apartments". In 1985, it completed a private
placement of units that raised net proceeds of approximately $2,928,000.
Buccaneer Trace Apartments consists of 208 apartment units. Your partnership has
no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2013, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $6,987,056, payable to 1st Union and
Lehman, which bears interest at a rate of 8.94%. The mortgage debt is due in May
2004. Your partnership also has a second mortgage note outstanding of $142,290,
on the same terms as the first mortgage note. Your partnership's agreement of
limited partnership also allows your general partner to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   532
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   533
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of $0
with respect to your units, distributions with respect to the Preferred OP Units
and Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   534
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   535
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
                                      S-30
<PAGE>   536
 
       However, one class of outstanding Partnership Preferred Units has prior
       distribution rights and the Tax-Deferral   % Preferred OP Units rank
       equal to six other outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   538
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   539
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   540
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   541
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   542
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   543
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units
tendered pursuant to the offer, may postpone the purchase of, and payment for,

     contract, or results of operations or prospects of your partnership or
     local markets in which your partnership owns or operates its property,
     including any fire, flood, natural disaster, casualty loss, or act of God
     that, in the sole judgment of the AIMCO Operating Partnership, is or may be
     materially adverse to your partnership or the value of your units to the
     AIMCO Operating Partnership, or the AIMCO Operating Partnership shall have
     become aware of any facts relating to your partnership, its indebtedness or
     its operations which, in the sole judgment of the AIMCO Operating

     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   546
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   548
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   549
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   550
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   551
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             its affiliates may purchase or acquire shares of Class

                                                             of Class I Preferred Stock. The redemption price for
                                                             the Class I Preferred Stock (other than any portion

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   556
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   557
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In addition, we considered the recent decline in the market for equity
securities including those of REIT, and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   559
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   560
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the six months ended June, 1998 were $2,640 (equivalent to $5,280 on an
     annualized basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral   % Preferred OP Units, or distributions
     of $          per year on the number of Tax-Deferral Common OP Units, that
     you would receive in exchange for each of your partnership's units.
     Therefore, distributions with respect to the Preferred OP Units and Common
     OP Units that we are offering are expected to be        , immediately
     following our offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   561
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 1/2 of
1% of the gross operating revenue of your partnership's property as a
partnership administration fee from your partnership and may receive
reimbursement for expenses generated in its capacity as general partner. The
property manager received management fees of $74,140 in 1996, $79,405 in 1997
and 34,705 for the first six months of 1998. The AIMCO Operating Partnership has
no current intention of changing the fee structure for the manager of your
partnership property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Buccaneer Trace Limited Partnership is a South Carolina limited partnership
which raised net proceeds of approximately $2,928,000 in 1985 through a private
offering. The promoter for the private offering of your partnership was US
Shelter Corp. Insignia acquired your partnership in December 1990. AIMCO
acquired Insignia in October, 1998. There are currently a total of 56 limited
partners of your partnership and a total of 61 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on October 31, 1985 for the purpose of owning
and operating a single apartment property located in Savannah, Georgia, known as
"Buccaneer Trace Apartments." Your partnership property consists of 208
apartment units. There are 48 one-bedroom apartments and 160 two-bedroom
apartments. The total rentable square footage of your partnership's property is
203,184 square feet. Your partnership's property had an average occupancy rate
of approximately 97.12% in 1996 and 97.12% in 1997. The average annual rent per
apartment unit is approximately $6,682.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during the first six months of 1998 was
$34,705.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2013
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $6,987,056, payable to 1st Union and Lehman, which bears interest
at a rate of 8.94%. The mortgage debt is due in May 2004. Your partnership also
has a second mortgage note outstanding of $142,290, on the same terms as the
first mortgage note. Your partnership's agreement of limited partnership also
allows the general partner of your partnership to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Income
 
     Your partnership recognized a net loss of $121,053 for the six months ended
June 30, 1998, compared to a net loss of $59,459 for the six months ended June
30, 1997. The decrease in net income of $61,594, or 103.59% was primarily the
result of increases in operating and interest expenses. These factors are
discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$676,278 for the six months ended June 30, 1998, compared to $695,809 for the
six months ended June 30, 1997, a decrease of $19,531, or 2.81%.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $246,728 for the
six months ended June 30, 1998, compared to $235,838 for the six months ended
June 30, 1997, an increase of $10,890 or 4.62%. Management expenses totaled
$34,705 for the six months ended June 30, 1998, compared to $36,300 for the six
months ended June 30, 1997, a decrease of $1,595, or 4.39%.
 
     General and Administrative Expenses
 
     Not Applicable
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $318,088 for the six months ended June 30, 1998, compared to
$287,968 for the six months ended June 30, 1997, an increase of $30,120, or
10.46%. The increase is due to circumstances surrounding the refinancing of the
mortgage in May of 1997.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized a net loss of $200,301 for the year ended
December 31, 1997, compared to a net loss of $155,641 for the year ended
December 31, 1996. The decrease in net income of $44,660, or 28.69% was
primarily the result of a decrease in rental revenues in 1997 and an increase in
operating expenses, offset by a decrease in interest expense.
 
     Rental and other property revenues from the partnership's property totaled
$1,457,767 for the year ended December 31, 1997, compared to $1,508,799 for the
year ended December 31, 1996, a decrease of $51,032, or 3.38%.

<PAGE>   581
 
for the year ended December 31, 1997, compared to $490,811 for the year ended
December 31, 1996, an increase of $105,663 or 21.53%. The increase is primarily
due to an increase in rental concessions and promotions to offset decreased
occupancy levels and is also due to gutter repair and painting projects at the
property. Management expenses totaled $72,925 for the year ended December 31,
1997, compared to $74,140 for the year ended December 31, 1996, a decrease of

$712,508 for the year ended December 31, 1996, a decrease of $110,469, or
15.50%. The decrease is primarily due to lower interest rates and a reduced
principal balance as a result of the refinancing of the mortgage.

31, 1995
 
     Net Income

     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership is not
liable to your partnership or the limited partners for any loss or damage
resulting from any act or omission performed or omitted in good faith, which
does not constitute fraud, gross negligence or willful misconduct, pursuant of
the authority granted to promote the interests of your partnership. Moreover,
the general partner will not be liable to your partnership or the limited
partner because any taxing authorities disallow or adjust any deduction or
credits in your partnership income tax returns. As a result, unitholders might
have a more limited right of action in certain circumstances than they would
have in the absence of such a provision in your partnership's agreement of
limited partnership. The general partner of your partnership is owned by AIMCO.
See "Conflicts of Interest".
 
     Under your partnership's agreement of limited partnership, the general
partner of your partnership are indemnified for any loss or damage resulting
from any act or omission performed or omitted in good faith, which does not
constitute fraud, gross negligence or willful misconduct, pursuant of the
authority granted to promote the interests of your partnership. Such
indemnification includes reasonable fees and expenses of attorneys engaged by
the general partner in defense of such act or omission and other reasonable
costs and expenses of litigation and appeal. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not paid any distributions during the last five years.
The original cost per unit was $54,348.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $

such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   591
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]

     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;

     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   592
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Burgundy Court Associates, L.P. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   597
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   598
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,960 per unit for the six months
     ended June 30, 1998 (equivalent to $7,920 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the quarter ended June 30, 1998, we paid distributions of
     $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25 on
     an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $       per year on the number of Tax-Deferral Common OP
     Units that you would receive in an exchange for each of your partnership's
     units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   600
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the Unites
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 in 759 apartment properties for third party owners and
       affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   603
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   604
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   605
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
                                      S-10
<PAGE>   606
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland
 
                                      S-11
<PAGE>   607
 
corporation, we are subject to various Maryland laws which may have the effect
of discouraging offers to acquire us and of increasing the difficulty of
consummating any such offers, even if our acquisition would be in our
stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. "Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources." Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your partnership without the offer
     would deny you and your partners the benefits that your general partner
     expects to result from the offer. For example, a partner of your
     partnership would have no opportunity for
 
                                      S-12
<PAGE>   608
 
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly

with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will

     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore

                                      S-14
<PAGE>   610
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
 
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions, liquidity and
transfer and redemption rights. See "Comparison of Preferred OP Units and Class
I Preferred Stock" for a chart highlighting such differences.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   611
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives a
monthly fee equal to 1% of the gross collected income from your partnership's
property as an administrative service fee from your partnership and may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $76,344 in 1996, $79,518 in 1997 and $40,874 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Burgundy Court Associates, L.P. is a
Delaware limited partnership which was formed on January 31, 1985 for the
purpose of owning and operating a single apartment property
 
                                      S-18
<PAGE>   614
 
located in Cincinnati, Ohio, known as "Burgundy Court Apartments". In 1985, it
completed a private placement of units that raised net proceeds of approximately
$1,850,000. Burgundy Court Apartments consists of 234 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2008, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,175,948, payable to FNMA, which bears
interest at a rate of 7.60%. The mortgage debt is due in November 2002. Your
partnership also has a second mortgage note outstanding of $112,855, on the same
terms as the first mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   622
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   623
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $3,960 per unit (equivalent to
$7,920 on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
 
                                      S-28
<PAGE>   624
 
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation
 
                                      S-29
<PAGE>   625
 
methods to estimate the fair market value of your partnership's assets. Instead,
such assets would be valued through negotiations with prospective purchasers (in
many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties may improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your Partnership may require funding from its partners. Continuation of
its operations may be dependent on additional funding from partners or from
other sources." Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   626
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   628
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   629
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   630
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   631
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought, or both). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   632
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Operating Partnership shall have become aware of any facts relating to your
     partnership, its indebtedness or its operations which, in the sole judgment

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to your partnership's business, or that certain
parts of your partnership's business might not have to be disposed of or other
substantial conditions complied with in order to obtain such approval or action,
any of which could cause the
 
                                      S-40
<PAGE>   636
 
     AIMCO Operating Partnership to elect to terminate the offer without
purchasing units hereunder. The AIMCO Operating Partnership's obligation to
purchase and pay for units is subject to certain conditions, including
conditions related to the legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts
 
                                      S-41
<PAGE>   637
 
     distributable upon liquidation, dissolution or winding up in preference or
priority to the holders of such interest (the Common OP Units and such other
interests are collectively referred to herein as "Junior Units"); (ii) on a
parity with the Class B Partnership Preferred Units, the Class C Partnership
Preferred Units, the Class D Partnership Preferred Units, the Class G
Partnership Preferred Units, the Class H Partnership Preferred Units, and with
any other interest in the AIMCO Operating Partnership if the holders of such
interest and the Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in proportion to their respective amounts of accumulated, accrued and unpaid
distributions or stated preferences, without preference or priority of one over
the other ("Parity Units"); and (iii) junior to the Class F Partnership
Preferred Units and any other interest in the AIMCO Operating Partnership if the
holders of such interest shall be entitled to the receipt of distributions or
amounts distributable upon liquidation, dissolution or winding up in preference
or priority to the holders of the Preferred OP Units ("Senior Units"). Junior
Units, Parity Units and Senior Units may be issued from time to time by the
AIMCO Operating Partnership without any approval or consent by holders of the
Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for
 
                                      S-42
<PAGE>   638
 
     such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.

<PAGE>   639
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   640
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   641
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   646
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   647
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   649
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   650
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
the Common OP Units are $2.25, and distributions with respect to your units for
the six months ended June 30, 1998 were $3,960 (equivalent to $7,920 on an
annualized basis). Therefore, distributions with respect to the Preferred OP
Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP Units --
Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   651
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   652
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's

     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a

local

     market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or

     communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives a
monthly fee equal to 1% of the gross collected income from your partnership's
property as an administrative service fee from your partnership and may be
reimbursed for expenses generated in that capacity. The property manager
received management fees of $76,344 in 1996, $79,518 in 1997 and $40,874 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Burgundy Court Associates, L.P. is a Delaware limited partnership which
raised net proceeds of approximately $1,850,000 in 1985 through a private
offering. The promoter for the private offering of your partnership was
Jacques-Miller. Insignia acquired your partnership in December 1991. AIMCO
acquired Insignia in October, 1998. There are currently a total of 53 limited
partners of your partnership and a total of 50 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on January 31, 1985 for the purpose of owning
and operating a single apartment property located in Cincinnati, Ohio, known as
"Burgundy Court Apartments". Your partnership's property consists of 234
apartment units. There are 32 one-bedroom apartments, 140 two-bedroom apartments
and 62 three-bedroom apartments. The total rentable square footage of your
partnership's property is 210,574 square feet. Your partnership's property had
an average occupancy rate of approximately 94.44% in 1996 and 94.44% in 1997.
The average annual rent per apartment unit is approximately $6,569.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $76,344, $79,518 and $40,874, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2008
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,175,948, payable to FNMA, which bears interest at a rate of
7.60%. The mortgage debt is due in November 2002. Your partnership also has a
second mortgage note outstanding of $112,855, on the same terms as the first
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Burgundy Court Limited
as of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

General Partners
Burgundy Court, Limited:
 
     We have audited the accompanying balance sheets of Burgundy Court, Limited

changes in partners' deficit and cash flows for the years then ended. These
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, a well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Burgundy Court, Limited as

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Burgundy Court, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated January 31,
1985. The Partnership owns and operates a 234 unit apartment complex, Burgundy
Court Apartments, in Cincinnati, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the straight-line method
based upon the estimated useful lives of various classes of assets; buildings
are depreciated over 25 years and the personal property assets are depreciated
over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$67,530 and $80,721, respectively, which are amortized over the term of the
related borrowing. They are shown net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

General Partners
Burgundy Court, Limited:
 
     We have audited the accompanying balance sheets of Burgundy Court, Limited
as of December 31, 1996 and 1995 and the related statements of operations and
changes in partners' deficit and cash flows for the years then ended. These
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Burgundy Court, Limited as
of December 31, 1996 and 1995, and the results of its operations and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Burgundy Court, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated January 31,
1985. The Partnership owns and operates a 234 unit apartment complex, Burgundy
Court Apartments, in Cincinnati, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the straight-line method
based upon the estimated useful lives of various classes of assets; buildings
are depreciated over 25 years and the personal property assets are depreciated
over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 consist of deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of counsel's opinion, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  Burgandy Court Associates, L.P.
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
Burgandy Court Associates, L.P. (the "Partnership") (the Purchaser, AIMCO, the
General Partner and other affiliates and subsidiaries of AIMCO are referred to
herein collectively as the "Company"), is contemplating a transaction (the
"Offer") in which a minority of the outstanding limited partnership interests in
the Partnership (the "Units") will be acquired by the Purchaser in exchange for
an offer price per Unit of $       in cash, or        Common OP Units of the
Purchaser, or        Preferred OP Units of the Purchaser, or a combination of
any of such forms of consideration. The limited partners of the Partnership (the
"Limited Partners") will have the choice to maintain their current interest in
the Partnership or exchange their Units for any or a combination of such forms
of consideration. The amount of cash, Common OP Units or Preferred OP Units
offered per Unit is referred to herein as the "Offer Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   695
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   696
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Calmark/Fort Collins, Ltd. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   701
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   702
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $14,705.88 per unit for the six
     months ended June 30, 1998 (equivalent to $29,411.76 on an annual basis).
     We will pay fixed quarterly distributions of $               per unit on
     the Tax-Deferral   % Preferred OP Units before any distributions are paid
     to holders of Tax-Deferral Common OP Units. We pay quarterly distributions
     on the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $     per year
     on the number of Tax-Deferral   % Preferred OP Units or distributions of
     $     per year on the number of Tax-Deferral Common OP Units that you would
     receive in exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if more than 50% or
     more of the total interests in your partnership are transferred within a
     12-month period. If we acquire a significant percentage of the interest in
     your partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using
 
                                       S-4
<PAGE>   704
 
     our best judgment, but our valuation is just an estimate. Although the
     direct capitalization method is a widely-accepted way of valuing real
     estate, there are a number of other methods available to value real estate,
     each of which may result in different valuations of the property. The
     proceeds that you would receive if you sold your units to someone else or
     if your partnership were actually liquidated might be higher or lower than
     our offer consideration. An actual liquidation may also result in your
     paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the
 
                                       S-5
<PAGE>   705
 
     expiration of the offer, and you must follow the instructions provided with
     the Letter of Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   707
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   708
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence
 
                                       S-9
<PAGE>   709
 
on matters affecting the operation of the AIMCO Operating Partnership and third
parties may find it difficult to attempt to gain control or influence the
activities of our operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
                                      S-10
<PAGE>   710
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S.
 
                                      S-11
<PAGE>   711
 
Treasury Department. Changes to the Federal laws and interpretations thereof
could adversely affect our investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
          Liquidation. One alternative to our offer would be for your
     partnership to sell its assets, distribute the net liquidation proceeds to
     its partners in accordance with your partnership's agreement of limited
     partnership, and then dissolve. Partners would be at liberty to use the net
     liquidation proceeds after taxes for investment, business, personal or
     other purposes, at their option. If your partnership were to sell its
     assets and liquidate, you and your partners would not need to rely upon
     capitalization of income or other valuation methods to estimate the fair
     market value of your partnership's assets. Instead, such assets would be
     valued through negotiations with prospective purchasers. However, a
     liquidating sale of your partnership's property would be a taxable event
     for you and your partners and could result in significant amounts of
     taxable income to you and your partners. Under your partnership's agreement
     of limited partnership, a sale of your partnership's assets and the
     subsequent liquidation of your partnership could occur only with the
     consent of the limited partners holding at least a majority of the units of
     your partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your
 
                                      S-12
<PAGE>   712
 
     pro rata share of the fair market value of your partnership's property and
     might involve significant expense and delay.
 
        Continuation of Your Partnership Without the Offer. A second alternative
     would be for your partnership to continue its business without our offer. A
     number of advantages could result from the continued operation of your
     partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources. Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your partnership without the offer
     would deny you and your partners the benefits that your general partner
     expects to result from the offer. For example, a partner of your
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                      S-13
<PAGE>   713
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly

sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;

     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We

                                      S-15
<PAGE>   715
 
     expenses in making the offer (excluding the purchase price of the units
payable to you and your partners) will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
 
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions, liquidity and
transfer and redemption rights. See "Comparison of Preferred OP Units and Class
I Preferred Stock" for a chart highlighting such differences.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" OF THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rate. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a
widely-accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
                                      S-17

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you, from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, there is no limitation on the liability of your partnership's
general partners to your partnership or any of the limited partners for acts
performed in their capacity as general partner. The general partner of the AIMCO
Operating Partnership has no liability to the AIMCO Operating Partnership or any
of the holders of OP Units for acts performed by the general partner in good
faith.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $30,621 in 1996, $32,886 in 1997 and $17,036 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.

     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Calmark/Fort Collins, Ltd. is a
California limited partnership which was formed on January 29, 1982 for the
purpose of owning and operating a single apartment property located in Fort
Collins, Colorado, known as "Scotch Pines East." In 1982, it completed a private
placement of units that raised net proceeds of approximately $1,411,000. Scotch
Pines East consists of 102 apartment units. Your partnership has no employees.
 
     Property Management. Since 1992, your partnership's property has been
managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2031, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,786,929, payable to Lehman, which
bears interest at a rate of 7.34%. The mortgage debt is due in December 2004.
Your partnership also has a second mortgage note outstanding of $2,786,929, on
the same terms as the first mortgage note. Your partnership's agreement of
limited partnership also allows your general partner to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.

SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer price from a financial
point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.

     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-28
<PAGE>   728
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $3,460 per unit (equivalent to
$7,920 on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership
 
                                      S-29
<PAGE>   729
 
were to be reduced, and you do not tender all of your units pursuant to our
offer, you will be treated as receiving a hypothetical distribution of cash
resulting from a decrease in your share of the liabilities of your partnership.
Any such hypothetical distribution of cash would be treated as a nontaxable
return of capital to the extent of your adjusted tax basis in your units and
thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX
PURPOSES. If there is a sale or exchange of 50% or more of the total interest in
capital and profits of your partnership within any 12-month period, including
sales or exchanges resulting from the offer, your partnership will terminate for
Federal income tax purposes. Any such termination may, among other things,
subject the assets of your partnership to longer depreciable lives than those
currently applicable to the assets of your partnership. This would generally
decrease the annual average depreciation deductions allocable to you if you do
not tender all of your units (thereby increasing the taxable income allocable to
your units each year), but would have no effect on the total depreciation
deductions available over the useful lives of the assets of your partnership.
Any such termination may also change (and possibly shorten) your holding period
with respect to your units that you choose to retain.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
                                      S-30
<PAGE>   730
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our
 
                                      S-31
<PAGE>   731
 
offer would deny you and your partners the benefits of diversification into a
company which has a much larger and more diverse portfolio of apartment
properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral      % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   733
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   734
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first

for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-35
<PAGE>   735
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-36
<PAGE>   736
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-37
<PAGE>   737
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Operating Partnership shall have become aware of any facts relating to your
     partnership, its indebtedness or its operations which, in the sole judgment

     Partnership, might affect the extension of credit by banks or other lending
     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-41
<PAGE>   741
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other

<PAGE>   742
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-43
<PAGE>   743
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-44
<PAGE>   744
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   745
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46
<PAGE>   746
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   751
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   752
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-55
<PAGE>   755
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-56
<PAGE>   756
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the six months ended June 30, 1998 were $3,460 (equivalent to $7,920 on
     an annualized basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units, that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-57
<PAGE>   757
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-58

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
                                      S-59
<PAGE>   759
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of
 
                                      S-61

     your partnership. Stanger relied upon the representations of your
partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $30,621 in 1996, $32,886 in 1997 and $17,036 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

in October, 1998. There are currently a total of 37 limited partners of your
partnership and a total of 34 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property

television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since 1992, your partnership's property has been managed by an entity which
is now an affiliate of AIMCO. Pursuant to the management agreement between the
property manager and your partnership, the property manager operates your
partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $30,621, $32,886 and $17,036, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is not limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2031
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is not is

contributed to your partnership by the limited partners, as well as the debt
financing obtained by your partnership within the established borrowing
restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."

7.34%. The mortgage debt is due in December 2004. Your partnership also has a
second mortgage note outstanding of $2,786,929, on the same terms as the first
mortgage note. Your partnership's agreement of limited partnership also allows

Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Your partnership's agreement of
limited partnership does not limit the liability of the general partners to your
Partners or the limited partners for any act performed in their capacity as
general partner. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest".
 
     Your partnership's agreement of limited partnership provides that the
general partners of your partnership and their affiliates are entitled to
indemnification from any expense, liability or loss, including attorneys' fees
incurred in connection with the defense of any action, based on any act or
omission by the general partners within the scope of the authority conferred by
your partnership's agreement of limited partnership, including all such
liabilities under Federal and state securities laws as permitted by law, except
for acts or omissions constituting fraud, bad faith, willful misconduct or gross
negligence. Such attorneys' fees may be paid as incurred. If such a claim for
indemnification (other than for expenses incurred in a successful defense) is
asserted against your partnership, your partnership will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question of whether such indemnification
by it is against public policy and will be governed by the final adjudication of
such issue. Your partnership is provide indemnification to the extent of its
assets. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

     The following table sets forth the distributions paid per unit in the

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been
 
                                      S-78

     limited and sporadic. The general partner of your partnership monitors
transfers of the units (a) because the admission of the transferee as a
substitute limited partner in your partnership require the consent of the
general partner of your partnership under your partnership's agreement of
limited partnership, and (b) in order to track compliance with safe harbor
provisions to avoid treatment as a "publicly traded partnership" for tax
purposes. However, the general partner of your partnership does not monitor or
regularly receive or maintain information regarding the prices at which
secondary sale transactions in the units have been effectuated. The general
partner of your partnership estimates, based solely on the transfer records of
your partnership (or your partnership's transfer agent), that there have been no
units transferred in sale transactions (excluding transactions believed to be
between related parties, family members or the same beneficial owner).

any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Calmark/Ft. Collins as
of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with the accounting basis for federal income tax
reporting. Accordingly, they do not include all the information and footnotes
required by the accounting basis for federal income tax reporting for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

1. ORGANIZATION
 
  Description of Partnership
 
     Calmark/Fort Collins, Ltd., a California limited partnership (the
"Partnership"), was formed in January 1982 to acquire and operate a 102-unit
apartment complex in Fort Collins, Colorado. This property was acquired from
Calmark Asset Management, Inc. (CAMI), an affiliate of the Corporate General
Partner, Calmark/Fort Collins, Inc., a California corporation.
 
     The Partnership will terminate on December 31, 2031 unless terminated
sooner by the retirement or dissolution of the General Partners or unless the
Partners elect to continue the Partnership.
 
     The General Partners of the Partnership are Calmark/Fort Collins, Inc., a
California corporation (the Corporate General Partner) and Fort Collins Company,
Ltd., a California limited partnership (Associate General Partner). In January
1993, MAE California, Inc., an affiliate of Insignia Financial Group, Inc.,
purchased all of the outstanding stock of the Corporate General Partner and
assumed the role and obligations of the Managing General Partner of the
Partnership.
 
  Allocations to Partners
 
     In general, income and losses from operations and losses upon sale of the
property and/or dissolution of the Partnership are allocated 1% to the General
Partners and 99% to the Limited Partners.
 
     Income from disposition or partial disposition of the Partnership's
property and income upon termination and liquidation of the Partnership will be
allocated as follows:
 
          a. Ordinary income under Section 751(c) of the Internal Revenue Code
     will be allocated between the Partners as a class in the same proportion as
     such deductions were allocated to them.
 
          b. To Partners with negative adjusted capital account balances (as
     defined), after accounting for distributions described below, in proportion
     to their negative adjusted capital account balances.
 
          c. Any remaining income will be allocated so as to produce a 25:75
     ratio between the aggregate positive adjusted capital account balances of
     the General Partners and the aggregate positive adjusted capital account
     balances of the Limited Partners after accounting for the distributions
     described below.
 
  Cash Distributions
 
     Net cash from operations (as defined) is to be distributed not less than
quarterly and not later than ninety days after the end of each fiscal quarter of
the Partnership in the following order of priority:
 
          a. To the General Partners an amount equal to the excess gross rental
     income (as defined), not to exceed $66,500.
 
          b. 1% to the General Partners and 99% to the Limited Partners as a
     class until such time as the Limited Partners have received in the
     aggregate an amount equal to an 8% per annum cumulative (but not
     compounded) return on their adjusted investment interest (as defined).
 
          c. The remainder is allocated 25% to the General Partners and 75% to
     the Limited Partners as a class. In general, any proceeds remaining after
     the sale of the properties and dissolution of the Partnership shall be

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Method of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Apartment Property
 
     The apartment property is stated at cost. Depreciation of the apartment
property has been provided using the accelerated cost recovery method (1) for
real property over 15 years and (2) for personal property over 5 years for
additions prior to January 1, 1987. As a result of the Tax Reform Act of 1986,
for additions after December 31, 1986, the modified accelerated cost recovery
method is used for depreciation of (1) real property additions over 27 1/2 years
and (2) personal property additions over 7 years.
 
  Replacement Reserve
 
     A replacement reserve account was established with the mortgagee, and these
funds are to be used to make necessary repairs and replacements of existing
equipment and improvements. The Partnership may be required to deposit
additional amounts on a monthly basis if the mortgagee determines in its sole
discretion that conditions warrant the deposits. At December 31, 1997, the
balance in the reserve account was $6,063.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits". Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit.

  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Loan Costs
 
     Loan costs are being amortized by the straight-line method over the term of
the related debt.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

Mortgage note payable to Lehman Brothers Holdings, Inc.
  secured by a first deed of trust on the property. This
  note bears interest at 7.34% per annum. Principal and
  interest payments of $19,272 are payable monthly, with a
  balloon payment of $2,584,606 due on December 1, 2004.....   $2,800,000

</TABLE>
 
     During 1997, the Partnership refinanced its long-term debt. The Partnership
recognized a loss on extinguishment of the old debt of $182,437 primarily due to
writing off unamortized debt discount and loan costs. In addition, the
Partnership incurred $66,404 in costs associated with the new debt. The new debt
contains prepayment penalties if repaid prior to maturity.
 
     Scheduled principal payments of long-term debt subsequent to December 31,
are as follows:

1. ORGANIZATION
 
  Description of Partnership
 
     Calmark/Fort Collins, Ltd., a California limited partnership (the
"Partnership"), was formed in January 1982 to acquire and operate a 102-unit
apartment complex in Fort Collins, Colorado. This property was acquired from
Calmark Asset Management, Inc. (CAMI), an affiliate of the Corporate General
Partner, Calmark/Fort Collins, Inc., a California corporation.
 
     The Partnership will terminate on December 31, 2031 unless terminated
sooner by the retirement or dissolution of the General Partners or unless the
Partners elect to continue the Partnership.
 
     The General Partners of the Partnership are Calmark/Fort Collins, Inc., a
California corporation (the Corporate General Partner) and Fort Collins Company,
Ltd., a California limited partnership (Associate General Partner). In January
1993, MAE California, Inc., an affiliate of Insignia Financial Group, Inc.,
purchased all of the outstanding stock of the Corporate General Partner and
assumed the role and obligations of the Managing General Partner of the
Partnership.
 
  Allocations to Partners
 
     In general, income and losses from operations and losses upon sale of the
property and/or dissolution of the Partnership are allocated 1% to the General
Partners and 99% to the Limited Partners.
 
     Income from disposition or partial disposition of the Partnership's
property and income upon termination and liquidation of the Partnership will be
allocated as follows:
 
          a. Ordinary income under Section 751(c) of the Internal Revenue Code
     will be allocated between the Partners as a class in the same proportion as
     such deductions were allocated to them.
 
          b. To Partners with negative adjusted capital account balances (as
     defined), after accounting for distributions described below, in proportion
     to their negative adjusted capital account balances.
 
          c. Any remaining income will be allocated so as to produce a 25:75
     ratio between the aggregate positive adjusted capital account balances of
     the General Partners and the aggregate positive adjusted capital account
     balances of the Limited Partners after accounting for the distributions
     described below.
 
  Cash Distributions
 
     Net cash from operations (as defined) is to be distributed not less than

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Method of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Apartment Property
 
     The apartment property is stated at cost. Depreciation of the apartment
property has been provided using the accelerated cost recovery method (1) for
real property over 15 years and (2) for personal property over 5 years for
additions prior to January 1, 1987. As a result of the Tax Reform Act of 1986,
for additions after December 31, 1986, the modified accelerated cost recovery
method is used for depreciation of (1) real property additions over 27 1/2 years
and (2) personal property additions over 7 years.
 
  Replacement Reserve
 
     A replacement reserve account was established with the mortgagee, and these
funds are to be used to make necessary repairs and replacements of existing
equipment and improvements. The Partnership may be required to deposit
additional amounts on a monthly basis if the mortgagee determines in its sole
discretion that conditions warrant the deposits. At December 31, 1996, the
balance in the reserve account was $5,739.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Restricted Cash
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage.

  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Loan Costs
 
     Loan costs are being amortized by the straight-line method over the term of
the related debt.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

Mortgage note payable to Metmor Financial, Inc. secured by a
  first deed of trust on the property. This note bears
  interest at 8.25% per annum. Principal and interest
  payments of $18,064 are payable monthly, with a balloon
  payment of $1,663,990 due on January 1, 2003..............   $2,039,225
Promissory note payable to E.E. Mitchell and Co. This note
  bears interest at 8.8% per annum. Interest and principal
  payments based on cash flow (as defined in the note) are
  made monthly. The unpaid principal and interest is due on
  December 1, 1997..........................................      168,600

Less unamortized loan discount fee..........................     (148,618)
                                                               ----------
                                                               $2,059,207
                                                               ==========
</TABLE>
 
     The Partnership exercised an interest rate buy-down option for the
refinanced mortgage note payable. This loan discount fee, amortized on a
straight-line basis over the life of the loan, is reflected as a reduction of
the mortgage note payable and increases the effective rate of the debt to
10.25%. The mortgage note payable is secured by pledge of the apartment property
and by pledge of revenues from the apartment property.

"Partnership"), was formed in January 1982 to acquire and operate a 102-unit
apartment complex in Fort Collins, Colorado. This property was acquired from
Calmark Asset Management, Inc. (CAMI), an affiliate of the Corporate General
Partner, Calmark/Fort Collins, Inc., a California corporation.
 
     The Partnership will terminate on December 31, 2031 unless terminated
sooner by the retirement or dissolution of the General Partners or unless the
Partners elect to continue the Partnership.
 
     The General Partners of the Partnership are Calmark/Fort Collins, Inc., a
California corporation (the Corporate General Partner) and Fort Collins Company,
Ltd., a California limited partnership (Associate General Partner). In January
1993, MAE California, Inc., an affiliate of Insignia Financial Group, Inc.,
purchased all of the outstanding stock of the Corporate General Partner and
assumed the role and obligations of the Managing General Partner of the
Partnership.
 
  Allocations to Partners
 
     In general, income and losses from operations and losses upon sale of the
property and/or dissolution of the Partnership are allocated 1% to the General
Partners and 99% to the Limited Partners.
 
     Income from disposition or partial disposition of the Partnership's
property and income upon termination and liquidation of the Partnership will be
allocated as follows:
 
          a. Ordinary income under Section 751(c) of the Internal Revenue Code
     will be allocated between the Partners as a class in the same proportion as
     such deductions were allocated to them.
 
          b. To Partners with negative adjusted capital account balances (as
     defined), after accounting for distributions described below, in proportion
     to their negative adjusted capital account balances.
 
          c. Any remaining income will be allocated so as to produce a 25:75
     ratio between the aggregate positive adjusted capital account balances of
     the General Partners and the aggregate positive adjusted capital account
     balances of the Limited Partners after accounting for the distributions
     described below.
 
  Cash Distributions
 
     Net cash from operations (as defined) is to be distributed not less than
quarterly and not later than ninety days after the end of each fiscal quarter of
the Partnership in the following order of priority:
 
          a. To the General Partners an amount equal to the excess gross rental
     income (as defined), not to exceed $66,500.
 
          b. 1% to the General Partners and 99% to the Limited Partners as a
     class until such time as the Limited Partners have received in the
     aggregate an amount equal to an 8% per annum cumulative (but not
     compounded) return on their adjusted investment interest (as defined).
 
          c. The remainder is allocated 25% to the General Partners and 75% to
     the Limited Partners as a class. In general, any proceeds remaining after
     the sale of the properties and dissolution of the Partnership shall be
     distributed to the Partners in accordance with their capital accounts after
     payment of certain items specified in the Partnership Agreement.

                  INCOME TAX BASIS (UNAUDITED) -- (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Method of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Apartment Property
 
     The apartment property is stated at cost. Depreciation of the apartment
property has been provided using the accelerated cost recovery method (1) for
real property over 15 years and (2) for personal property over 5 years for
additions prior to January 1, 1987. As a result of the Tax Reform Act of 1986,
for additions after December 31, 1986, the modified accelerated cost recovery
method is used for depreciation of (1) real property additions over 27 1/2 years
and (2) personal property additions over 7 years.
 
  Replacement Reserve
 
     A replacement reserve account was established with the mortgagee, and these
funds are to be used to make necessary repairs and replacements of existing
equipment and improvements. The Partnership may be required to deposit
additional amounts on a monthly basis if the mortgagee determines in its sole
discretion that conditions warrant the deposits. At December 31, 1995, the
balance in the reserve account was $4,505.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Restricted Cash
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage.

                    NOTES TO FINANCIAL STATEMENTS -- FEDERAL
                  INCOME TAX BASIS (UNAUDITED) -- (CONTINUED)
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Loan Costs
 
     Loan costs are being amortized by the straight-line method over the term of
the related debt.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
3. OTHER ASSETS
 
     Other assets consist of the following at December 31, 1995:

4. LONG-TERM DEBT
 
     Long-term debt payable at December 31, 1995 consists of the following:
 
<TABLE>

Mortgage note payable to Metmor Financial, Inc. secured by a
  first deed of trust on the property. This note bears
  interest at 8.25% per annum. Principal and interest
  payments of $18,064 are payable monthly, with a balloon
  payment of $1,663,990 due on January 1, 2003..............   $2,081,931
Promissory note payable to E.E. Mitchell and Co. This note
  bears interest at 8.8% per annum. Interest and principal
  payments based on cash flow (as defined in the note) are
  made monthly. The unpaid principal and interest is due on
  December 1, 1997..........................................      242,841

Less unamortized loan discount fee..........................     (173,737)
                                                               ----------
                                                               $2,151,035
                                                               ==========
</TABLE>
 
     The Partnership exercised an interest rate buy-down option for the
refinanced mortgage note payable. This loan discount fee, amortized on a
straight-line basis over the life of the loan, is reflected as a reduction of
the mortgage note payable and increases the effective rate of the debt to
10.25%. The mortgage note payable is secured by pledge of the apartment property
and by pledge of revenues from the apartment property.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   810
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   811
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Calmark Heritage Park II Ltd. For each unit that you tender, you may choose
     to receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   816
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   817
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership has never made a distribution. We will pay fixed quarterly
     distributions of $               per unit on the Tax-Deferral   % Preferred
     OP Units before any distributions are paid to holders of Tax-Deferral
     Common OP Units. We pay quarterly distributions on the Tax-Deferral Common
     OP Units based on our funds from operations for that quarter. For the six
     months ended June 30, 1998, we paid distributions of $1.125 on each of the
     Tax-Deferral Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

<PAGE>   818
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if 50% or more of the
     total interests in your partnership are transferred within a 12-month
     period. If we acquire a significant percentage of the interest in your
     partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership. In addition, there is a sale or exchange of 50% or more of the
     total interest in capital and profits of your partnership within any
     12-month period, including sales or exchanges resulting from the offer,
     your partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your
 
                                       S-4
<PAGE>   819
 
     partnership using the direct capitalization method. This method involves
     applying a capitalization rate to your partnership's annual net operating
     income. We determined an appropriate capitalization rate using our best
     judgment, but our valuation is just an estimate. Although the direct
     capitalization method is a widely-accepted way of valuing real estate,
     there are a number of other methods available to value real estate, each of
     which may result in different valuations of the property. The proceeds that
     you would receive if you sold your units to someone else or if your
     partnership were actually liquidated might be higher or lower than our
     offer consideration. An actual liquidation may also result in your paying
     taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
                                       S-5
<PAGE>   820
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   822
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   823
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   824
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   825
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   826
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent the
     limited partners holding of at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
 
                                      S-12
<PAGE>   827
 
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership has required funding from its partners. Continuation of its
     operations is dependent on additional funding from partners or from other
     sources. Your partnership faces maturity or balloon payment dates on its
     mortgage loans and must either obtain refinancing or sell its property. If
     your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your partnership without the offer
     would deny you and your partners the benefits that your general partner
     expects to result from the offer. For example, a partner of your
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
                                      S-13
<PAGE>   828
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

on               , 1998, unless extended.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;

     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the
 
                                      S-17
<PAGE>   832
 
fairness opinion. Based on its analysis, and subject to the assumptions,
limitations and qualifications cited in its opinion, Stanger concluded that our
offer consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $333,000 in 1996, $269,000 in 1997 and $135,829 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.

     Property Management. Since 1992, your partnership's property has been
managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on March 9, 2011, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage notes outstanding on Heritage Park Escondido Apartments of
$6,150,000, Heritage Park Livermore Apartments of $6,870,000 and Heritage
Village Anaheim Apartments of $7,685,000 payable to Wells Fargo and First Trust

is $4,980,103, as of June 30, 1998. The note is payable to GMAC, bears interest

your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   841
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
 
                                      S-27
<PAGE>   842
 
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions, with respect
to the Preferred OP Units are $       , current annualized distributions with
respect to the Common OP Units are $2.25. The partnership has never made a
distribution to its limited partners. Therefore, distributions with respect to
the Preferred OP Units and Common OP Units that we are offering are expected to
be           , immediately following our offer, than the distribution with
respect to your units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your
 
                                      S-28
<PAGE>   843
 
partnership. Any such hypothetical distribution of cash would be treated as a
nontaxable return of capital to the extent of your adjusted tax basis in your
units and thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX
PURPOSES. If there is a sale or exchange of 50% or more of the total interest in
capital and profits of your partnership within any 12-month period, including
sales or exchanges resulting from the offer, your partnership will terminate for
Federal income tax purposes. Any such termination may, among other things,
subject the assets of your partnership to longer depreciable lives than those
currently applicable to the assets of your partnership. This would generally
decrease the annual average depreciation deductions allocable to you if you do
not tender all of your units (thereby increasing the taxable income allocable to
your units each year), but would have no effect on the total depreciation
deductions available over the useful lives of the assets of your partnership.
Any such termination may also change (and possibly shorten) your holding period
with respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own limited partnership interests in your partnership.
 
                                      S-29
<PAGE>   844
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your Partnership has required funding from its partners. Continuation of
its operations is dependent on additional funding from partners or from other
sources. Your
 
                                      S-30
<PAGE>   845
 
partnership faces maturity or balloon payment dates on its mortgage loans and
must either obtain refinancing or sell its property. If your partnership were to
continue operating as presently structured, your partnership could be forced to
borrow on terms that could result in net losses from operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership. However, one class of outstanding Partnership Preferred
       Units has prior distribution rights and the Tax-Deferral   % Preferred OP
       Units rank equal to six other outstanding classes of Partnership
       Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the
 
                                      S-31
<PAGE>   846
 
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   848
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   849
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

Obligation to Give Notice of Defects
 
                                      S-35
<PAGE>   850
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.

EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of considerations being offered, or increasing or decreasing the
percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
                                      S-37
<PAGE>   852
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments
 
                                      S-38
<PAGE>   853
 
     to your partnership's agreement of limited partnership. See "Comparison of
Your Units and AIMCO OP Units -- Voting Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

Partnership shall not be required to accept for payment and pay for any units

     existing at the time of the commencement of the offer, in the sole judgment
     of the AIMCO Operating Partnership, a material acceleration or worsening
     thereof; or

     action, proceeding, application or counterclaim by any Federal, state,

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to your partnership's business, or that certain
parts of your partnership's business might not have to be disposed of or other
substantial conditions complied with in order to obtain such approval or action,
any of which could cause the AIMCO Operating Partnership to elect to terminate
the offer without purchasing units hereunder. The
 
                                      S-41
<PAGE>   856
 
     AIMCO Operating Partnership's obligation to purchase and pay for units is
subject to certain conditions, including conditions related to the legal matters
discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such
 
                                      S-42
<PAGE>   857
 
     interest (the Common OP Units and such other interests are collectively
referred to herein as "Junior Units"); (ii) on a parity with the Class B
Partnership Preferred Units, the Class C Partnership Preferred Units, the Class
D Partnership Preferred Units, the Class G Partnership Preferred Units, the
Class H Partnership Preferred Units, and with any other interest in the AIMCO
Operating Partnership if the holders of such interest and the Preferred OP Units
shall be entitled to the receipt of distributions and amounts distributable upon
liquidation, dissolution or winding up in proportion to their respective amounts
of accumulated, accrued and unpaid distributions or stated preferences, without
preference or priority of one over the other ("Parity Units"); and (iii) junior
to the Class F Partnership Preferred Units and any other interest in the AIMCO
Operating Partnership if the holders of such interest shall be entitled to the
receipt of distributions or amounts distributable upon liquidation, dissolution
or winding up in preference or priority to the holders of the Preferred OP Units
("Senior Units"). Junior Units, Parity Units and Senior Units may be issued from
time to time by the AIMCO Operating Partnership without any approval or consent
by holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for
 
                                      S-43
<PAGE>   858
 
     payment by the AIMCO Operating Partnership with respect to any Parity
Units. Unless full cumulative distributions (including all accumulated, accrued
and unpaid distributions) on the Preferred OP Units have been declared and paid,
or declared and set apart for payment, for all past distribution periods, no
distributions (other than distributions or distributions paid in Junior Units or
options, warrants or rights to subscribe for or purchase Junior Units) may be
declared or paid or set apart for payment by the AIMCO Operating Partnership and
no other distribution of cash or other property may be declared or made,
directly or indirectly, by the AIMCO Operating Partnership with respect to any
Junior Units, nor shall any Junior Units be redeemed, purchased or otherwise
acquired (except for a redemption, purchase or other acquisition of Common OP
Units made for purposes of an employee incentive or benefit plan of AIMCO, the
AIMCO Operating Partnership or any subsidiary) for any consideration (or any
monies be paid to or made available for a sinking fund for the redemption of any
such Junior Units), directly or indirectly, by the AIMCO Operating Partnership
(except by conversion into or exchange for Junior Units, or options, warrants or
rights to subscribe for or purchase Junior Units), nor shall any other cash or
other property be paid or distributed to or for the benefit of holders of Junior
Units. Notwithstanding the foregoing provisions of this paragraph, the AIMCO
Operating Partnership shall not be prohibited from (i) declaring or paying or
setting apart for payment any distribution on any Parity Units or (ii)
redeeming, purchasing or otherwise acquiring any Parity Units, in each case, if
such declaration, payment, redemption, purchase or other acquisition is
necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.

REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46
<PAGE>   861
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   866
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   867
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-55
<PAGE>   870
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-56
<PAGE>   871
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions, with respect to the Preferred
     OP Units are $       , current annualized distributions with respect to the
     Common OP Units are $2.25. The partnership has never made a distribution to
     its limited partners. This is equivalent to distributions of $  per year on
     the number of Tax-Deferral Common OP Units, that you would receive in
     exchange for each of your partnership's units. Therefore, distributions
     with respect to the Preferred OP Units and Common OP Units that we are
     offering are expected to be           , immediately following our offer,
     than the distribution with respect to your units. See "Comparison of
     Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method
 
                                      S-57
<PAGE>   872
 
     described in "Valuation of Units" provides a meaningful indication of value
for residential apartment properties although there are other ways to value real
estate. A liquidation in the future might generate a higher price for holders of
units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   873
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF MATERIALS CONSIDERED
 
     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and
through June 30, 1998; (v) reviewed operating budgets for your partnership's
property for 1998, as prepared by your partnership; (vi) reviewed information
prepared by management relating to any debt encumbering your partnership's
property; (vii) reviewed information regarding market rental rates and
conditions for apartment properties in the general market area of your
partnership's property and other information relating to acquisition criteria
for apartment properties; (viii) reviewed internal financial analyses and
forecasts prepared by your partnership of the estimated current net liquidation
value of your partnership; (ix) reviewed information provided by AIMCO
concerning the AIMCO Operating Partnership, the Common OP Units and the
Preferred OP Units; and (x) conducted other studies, analysis and inquiries as
Stanger deemed appropriate.
 
     In addition, Stanger discussed with management of your partnership and
AIMCO the market conditions for apartment properties, conditions in the market
for sales/acquisitions of properties similar to that owned by your partnership,
historical, current and projected operations and performance of your
partnership's property and your partnership, the physical condition of your
partnership's property including any deferred maintenance, and other factors
influencing value of your partnership's property and your partnership. Stanger
also performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and

     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not

     limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the

     value of the partnership's property or other balance sheet assets and
liabilities or other information reviewed between the date of such information
provided and the date of the Fairness Opinion; that your partnership, AIMCO, and
the management of the partnership's property are not aware of any information or
facts that would cause the information supplied to Stanger to be incomplete or
misleading; that the highest and best use of the partnership's property is as
improved; and that all calculations were made in accordance with the terms of
your partnership's agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $333,000 in 1996, $269,000 in 1997 and $135,829 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under

$6,142,000 for the year ended December 31, 1996, compared to $6,272,954 for the
year ended December 31, 1995, a decrease of $130,954, or 2.09%.

the year ended December 31, 1996, compared to $2,509,899 for the year ended
December 31, 1995, a decrease of $125,899 or 5.02%. The decrease is primarily
due to reduced property expenses after the foreclosure of one of the
partnership's properties during 1996. Management expenses totaled $333,000 for
the year ended December 31, 1996, compared to $334,527 for the year ended

                                      S-77
<PAGE>   892
 
     primarily due to an increase in professional and other administration fees
associated with the bankruptcy proceedings.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $2,404,000 for the year ended December 31, 1996, compared to
$2,635,984 for the year ended December 31, 1995, a decrease of $231,984, or
8.80%. The decrease results from the extinguishment of one mortgage related to
the foreclosure of one of the properties in mid-1996.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $776,466 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Your partnership's agreement of
limited partnership does not limit the liability of the general partners to your
partnership or the limited partners for any act performed in their capacity as
general partner. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest."
 
     Your partnership's agreement of limited partnership does provide that your
partnership will indemnify the general partners of your partnership and their
affiliates are entitled to indemnification from any expense, liability or loss,
including attorney's fees incurred in connection with the defense of any action
or omission by the general partners performed within the scope of the authority
conferred by your partnership's agreement of limited partnership, except for
acts or omissions constituting fraud, bad faith, willful misconduct or gross
negligence. Notwithstanding the foregoing, your partnership will not indemnify
any person for any liabilities under federal and state securities law unless (i)
there has been a successful adjudication on the merits of each count involving
alleged securities law violations, (ii) such claims have been dismissed with
prejudice on the merits by a court of competent jurisdiction or (iii) a court of
competent jurisdiction approves a settlement of the claims. If a claim of
indemnification (other than for expenses incurred in a successful defense) is
asserted against your partnership, your partnership will notify the court of the
position of the SEC with respect to the issue of indemnification for securities
law violations. Such indemnification paid by your partnership will be to the
extent of your partnership assets. As part of its assumption of liabilities in
the consolidation, AIMCO will indemnify the general partner of your partnership
and their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     The general partners may, on behalf of your partnership, obtain a general
partner liability insurance policy at your partnership's expense that would
insure the general partners and their affiliates for liabilities they may incur
with respect to claims made against them for certain wrongful or allegedly
wrongful acts, including certain errors, misstatements, misleading statement,
omissions, neglect or breached of duty, provided that your partnership will not
be required to pay the premiums for this policy to the extent of coverage for
those acts and omission as to which the foregoing parties could not receive
indemnification under your partnership's agreement of limited partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not made distribution in the last five years. The
original cost per unit was $582,813.
 
                                      S-78
<PAGE>   893
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner) was as follows:

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

If the offer had been made in such prior periods, there would not have been any
material difference in the compensation and distributions that would have been
paid to the general partner of your partnership, or the company paid to the
property manager or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.
 
     Below is an itemized statement of the estimated expenses incurred and to be

NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Calmark Heritage Park II
Ltd. as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with generally accepted accounting principles
for interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that accounting measurements at interim dates inherently
involve greater reliance on estimates than at year-end. The results of
operations for the interim periods presented are not necessarily indicative of
the results for the entire year.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Calmark Heritage Park II Limited Partnership
 
     We have audited the accompanying balance sheet of Calmark Heritage Park II
Limited Partnership as of December 31, 1997, and the related statements of
operations, changes in partners' deficit and cash flows for the year then ended.
These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Calmark Heritage Park II
Limited Partnership at December 31, 1997, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.
 
     The accompanying financial statements have been prepared assuming that
Calmark Heritage Park II Limited Partnership will continue as a going concern.
As more fully described in Note A, the Partnership has incurred recurring
operating losses and is currently in default on a portion of its long-term debt.
In addition, the letters of credit which provide additional security on
$22,305,000 in indebtedness expire in June 1998. These conditions raise
substantial doubt about the Partnership's ability to continue as a going
concern. Management's plans in regard to these matters are also described in
Note A. The financial statements do not include any adjustments to reflect the
possible future effects on the recoverability and classification of assets or
the amounts and classification of liabilities that may result from the outcome
of this uncertainty.

                                 (IN THOUSANDS)
 
NOTE A -- GOING CONCERN
 
     The accompanying financial statements have been prepared assuming Calmark
Heritage Park II Limited Partnership (the "Partnership") will continue as a
going concern. The Partnership has incurred recurring operating losses and is in
default on a portion of its long term debt.
 
     The Partnership incurred an operating loss of approximately $498,000 for
the year ended December 31, 1997, before the gain recognized on the sale of an
investment property. As of December 31, 1997, there is a partners' deficit of
approximately $6,565,000. The Partnership realized positive cash flow of
approximately $598,000 for 1997, due primarily to net proceeds received from the
sale of an investment property.
 
     The Partnership has indebtedness under three 1992 Series A Bond Issues,
with a balance at December 31, 1997 of $22,305,000. These bonds are secured by
first deeds of trust on the Anaheim, Escondido, and Livermore properties. The
Letters of Credit on these bonds expired in November 1997, and the Partnership
has received extensions through June 1998. The bonds are in default due to a
violation of the loan agreements that require letters of credit for a minimum of
one year. Management is presently in negotiations with the Trustees to re-write
the bonds in order to obtain more favorable terms.
 
     The subordinated debt for Anaheim and Escondido matured in January 1997.
The Escondido note in the amount of $950,000, plus related accrued interest was
extended until March 1998; however, the extension has expired and such amounts
are in default due to nonpayment. The Partnership has received an extension
through May 15, 1998 for the Anaheim note. Management is also in negotiations to
modify these subordinated notes.
 
     There can be no assurance that these negotiations with the lenders will be
successful. Currently, there are no plans to sell any of the remaining
properties. The financial statements do not include any adjustments to reflect
the possible future effects on the recoverability and classification of assets
or amounts and classification of liabilities that may result from this
uncertainty.
 
NOTE B -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership was formed in November 1986 to acquire and operate senior
citizens apartment communities located in California and Nevada.
 
     The Partnership will terminate on March 9, 2011 unless terminated sooner by
vote of the Limited Partners or other dissolution. Other dissolution may occur
upon the bankruptcy or dissolution of a General Partner unless the Partners
elect to continue the Partnership.
 
     The General Partners of the Partnership are Heritage Park Investors, Inc.,
a California corporation (the Managing General Partner), Calmark Investors,
Ltd., a California Limited Partnership (the Associate General Partner), and
Heritage Park II, Inc., a Delaware corporation (the Lehman General Partner).
 
  Allocations to Partners
 
     Income and Losses
 
     Income from operations is allocated pro rata to the General Partners and to
the Limited Partners (collectively the "Partners") as a class in the same ratio
as cash distributions are made to such partners (see below). In the event that
no cash distributions are made to the Partners during any year, income from
operations shall be allocated 1% to the General Partners and 99% to the Limited
Partners.

                  CALMARK HERITAGE PARK II LIMITED PARTNERSHIP
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Losses from operations are generally allocated 1% to the General Partners
and 99% to the Limited Partners. Income from disposition or partial disposition
of Partnership property and income upon termination and liquidation of the
Partnership will be allocated as follows:
 
          a.  To Partners with negative adjusted capital account balances (as
              defined), after accounting for distributions described below, in

  Investment Properties
 
     Investment properties are recorded at cost. Depreciation is provided by the
straight-line method over the estimated lives of the investment properties and
related personal property.
 
  Loan Costs
 
     Loan costs are amortized on a straight-line basis over the lives of the
respective debt.
 
  Cash and Cash Equivalents

  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue

tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Indebtedness under three 1992 Series A Bond Issues to
  various housing authorities bearing interest at variable
  rates, secured by first deeds of trust on the Anaheim,
  Escondido, and Livermore properties. Interest payments to
  the trustee are required semi-annually; the rate is reset
  every seven days and is to be that which would produce a
  par bid if the bonds were sold on the first day of the
  next seven-day reset period. The average annual interest
  rates for 1997 was 3.5%. Two of the bond issues mature in
  2007 and one in 2022; they can be redeemed prior to

the Managing General Partner acquired, in the acquisition of a business, certain
financial obligations from an insurance agency which was later acquired by the
agent who placed the current year's master policy. The current agent assumed the
financial obligations to the affiliate of the Managing General Partner, who
received payments on these obligations from the agent. The amount of the
Partnership's insurance premiums that accrued to the benefit of the affiliate of
the Managing General Partner by virtue of the agent's obligations was not
significant.
 
NOTE F -- SALE OF PROPERTY
 
     On January 21, 1997, the Partnership sold Heritage Park Las Vegas to an
unaffiliated party. The buyer assumed the mortgage note payable which had an
outstanding balance of approximately $5,027,000. The Partnership received net
proceeds of approximately $907,000 after payment of closing costs. This
disposition resulted in a gain of approximately $1,532,000.
 
NOTE G -- YEAR 2000 (UNAUDITED)
 
     The Partnership is dependent upon Insignia for management and
administrative services. Insignia has completed an assessment and will have to
modify or replace portions of its software so that its computer systems will
function properly with respect to dates in the year 2000 and thereafter (the
"Year 2000 Issue"). The project is estimated to be completed not later than
December 31, 1998, which is prior to any anticipated impact on its operating
systems. Insignia believes that with modifications to existing software and
conversions to new software, the Year 2000 Issue will not pose significant
operational problems for its computer systems. However, if such modifications
and conversions are not made, or are not completed timely, the Year 2000 Issue
could have a material impact on the operations of the Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Calmark Heritage Park II Limited Partnership
 
     We have audited the accompanying balance sheet of Calmark Heritage Park II
Limited Partnership as of December 31, 1996, and the related statements of
operations, changes in partners' deficit and cash flows for the year then ended.
These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Calmark Heritage Park II
Limited Partnership at December 31, 1996, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.
 
     The accompanying financial statements have been prepared assuming that
Calmark Heritage Park II Limited Partnership will continue as a going concern.
As more fully described in Note A, the Partnership has incurred recurring
operating losses and is currently in default on substantially all of its
long-term debt. These conditions raise substantial doubt about the Partnership's
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note A. The financial statements do not include
any adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

                  CALMARK HERITAGE PARK II LIMITED PARTNERSHIP
 
                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
NOTE A -- GOING CONCERN
 
     The accompanying financial statements have-been prepared assuming Calmark
Heritage Park II Limited Partnership ("the Partnership") will continue as a
going concern.
 
     The Partnership is currently in default on substantially all of its
long-term debt. The Partnership has also incurred recurring operating losses and
has a partners' deficit at December 31, 1996. These conditions raise substantial
doubt about the Partnership's ability to continue as a going concern.
 
     Management is involved in discussions with its lenders in attempt to
restructure the debt which is in default. The outcome of these discussions is
not presently determinable and the financial statements do not include any
adjustments to reflect the possible future effects on the recover ability and
classification of assets or amounts and classification of liabilities that may
result from this uncertainty.
 
NOTE B -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership (formerly known as Shearson/Calmark Heritage Park II, Ltd.,
a California Limited Partnership) was formed in November 1986 to acquire and
operate senior citizens apartment communities located in California and Nevada.
 
     The Partnership will terminate on March 9, 2011 unless terminated sooner by
vote of the Limited Partners or other dissolution. Other dissolution may occur
upon the bankruptcy or dissolution of a General Partner unless the Partners
elect to continue the Partnership.
 
     The General Partners of the Partnership are Heritage Park Investors, Inc.,
a California corporation (the Managing General Partner), Calmark Investors,
Ltd., a California Limited Partnership (the Associate General Partner), and
Heritage Park II, Inc., a Delaware corporation (the Lehman General Partner).
 
  Allocations to Partners
 
     Income and Losses
 
     Income from operations is allocated pro rata to the General Partners and to
the Limited Partners (collectively the "Partners") as a class in the same ratio
as cash distributions are made to such partners (see below). In the event that
no cash distributions are made to the Partners during any year, income from
operations shall be allocated 1% to the General Partners and 99% to the Limited
Partners.
 
     Losses from operations are generally allocated 1% to the General Partners
and 99% to the Limited Partners. Income from disposition or partial disposition
of Partnership property and income upon termination and liquidation of the
Partnership will be allocated as follows:
 
          a.  To Partners with negative adjusted capital account balances (as
              defined), after accounting for distributions described below, in
              proportion to their negative adjusted capital account balances.
 
          b.  Any remaining income will be allocated 5% to the Lehman General
              Partner, 25% to the Managing General Partner and Associate General
              Partner and 70% to the Limited Partners.
 
     Losses from disposition or partial disposition of the Partnership property
and all losses upon the termination and liquidation of the Partnership shall be
allocated as follows:
 
          a.  To all Partners with positive adjusted capital balances in
              proportion to their adjusted capital balances.

                  CALMARK HERITAGE PARK II LIMITED PARTNERSHIP
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
          b.  Any remaining losses will be allocated 1% to the General Partners
              and 99% to the Limited Partners.
 
     Cash Distributions
 
     Cash from operations is to be distributed, when available, not less often
than quarterly and not later than ninety days after the end of each fiscal
quarter of the Partnership in the following order of priority:
 
          a.  1% collectively to the Managing General Partner and the Associate
              General Partner and 99% to the Limited Partners as a class until
              such time as the Limited Partners have received in the aggregate
              an amount equal to a 10% per annum cumulative (but not compounded)
              return on their adjusted interest investment (as defined).
 
          b.  The remainder is allocated 25% collectively to the Managing
              General Partner and the Associate General Partner, 5% to the
              Lehman General Partner and 70% to the Limited Partners as a class.
 
     In general, any proceeds remaining after the sale of the properties and
dissolution of the Partner ship shall be distributed to the Partners in
accordance with their capital accounts.
 
  Investment Properties
 
     The Partnership accounts for its investment properties under FASB Statement
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of", which requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount. The impairment loss is measured by
comparing the fair value of the asset to its carrying amount.
 
  Depreciation
 
     Depreciation is provided by the straight-line method over the estimated
lives of the investment properties and related personal property.
 
  Loan Costs
 
     Loan costs are amortized on a straight-line basis over the lives of the
respective debt.
 
  Cash and Cash Equivalents -- Unrestricted Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
NOTE C -- LONG-TERM DEBT
 
     Long-term debt at December 31, 1996 consists of the following (in
thousands):

  rates, secured by first deeds of trust on the Anaheim,
  Escondido, and Livermore properties. Interest payments to

  every seven days and is to be that which would produce a
  par bid if the bonds were sold on the first day of the
  next seven-day reset period. The average annual interest

  principal amounts are due in 2084. The Escondido note in
  the amount of $950,000 bears interest at 12% per annum,

Series A Bond Issues.
 
     The Partnership has irrevocable letters of credit with First Interstate
Bank in the amounts of $8,554,000 (Anaheim), $7,347,000 (Escondido) and
$7,668,000 (Livermore), respectively. These letters of credit are additional
security for the 1992 Series A Bond Issues, and are secured by second deeds of
trust on the Anaheim, Escondido and Livermore properties. The Partnership is
required to pay monthly servicing fees of

approximately 1% per annum, based on the out standing amounts. The Partnership
also has a standby letter of credit in the amount of $8,980,000 which is
additional security for the Anaheim letter of credit.
 
     The Partnership is required to fund a Cash Collateral Account and Debt
Service Reserve Account, based on monthly net cash flow as defined, from these
three properties, up to a maxi mum of $1,200,000 and $400,000, respectively. The
Debt Service Reserve Account is to be funded from monthly net cash flow after
the Cash Collateral Account has been fully funded. These Accounts serve as
additional collateral for the bonds. At December 31, 1996, the balances in the
Cash Collateral Account and Debt Service Reserve were $1,404,000 and $-0-,
respectively.
 
     The Partnership has a money market account which is restricted as
additional collateral for the Las Vegas mortgage note payable. The balance in
this cash collateral account at December 31, 1996 was $113,000.
 
     The debt encumbering Las Vegas Apartments matured in April 1996. The
Partnership negotiated with the lender an extension on the debt through July
1997. The property was subsequently sold in January 1997 to Heritage Park
Associates, LLC. See Note F concerning this sale.
 
     The mortgage note payable on the Las Vegas property and the subordinated
mortgage notes payable on the Anaheim, Escondido, and Livermore properties are
in default at December 31, 1996, due to cross default provisions on the Bonds.
In addition, the subordinated mortgage notes payable on the Anaheim and
Escondido properties were extended from their original maturity date of January
1, 1997 to February 1, 1997 (Anaheim) and March 1, 1997 (Escondido). The
Partnership was unable to pay off the debt at the extended maturity dates which
caused an additional event of default on this debt.
 
     In July 1996, Praedium Chesapeake, LLC executed a non-contested foreclosure
on the Norco property. The $2,158,000 mortgage note payable had been in default
since January 1995. As a result of the foreclosure, the mortgage note payable
was satisfied resulting in a gain to the Partnership of $1,004,000.
 
     Principal maturities of long-term debt at December 31, 1996 are as follows

     The Partnership insures its properties under a master policy through an
agency and insurer unaffiliated with the Managing General Partner. An affiliate
of the Managing General Partner acquired, in the acquisition of a business,
certain financial obligations from an insurance agency which was later acquired
by the agent who placed the current year's master policy. The current agent
assumed the financial obligations to the affiliate of the Managing General
Partner, who receives payments on these obligations from the agent. The amount
of the Partnership's insurance premiums accruing to the benefit of the affiliate
of the Managing General Partner by virtue of the agent's obligations is not
significant.
 
NOTE F -- SUBSEQUENT EVENT -- SALE OF PROPERTY
 
     On January 21, 1997, the Partnership sold Heritage Park Las Vegas to an
unaffiliated party. The buyer assumed the mortgage note payable which had an
outstanding balance of approximately $5,027,000. The Partnership received net
proceeds of approximately $900,000 after payment of closing costs. This
disposition resulted in a gain of approximately $1,500,000.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Calmark Heritage Park II Limited Partnership (formerly known as
Shearson/Calmark Heritage Park II, Ltd., a California Limited Partnership) ("the
Partnership"), was formed in November 1986 to acquire and operate senior
citizens apartment communities located in California and Nevada.
 
     The Partnership will terminate on March 9, 2011 unless terminated sooner by
vote of the Limited Partners or other dissolution. Other dissolution may occur
upon the bankruptcy or dissolution of a General Partner unless the Partners
elect to continue the Partnership.
 
     The General Partners of the Partnership are Heritage Park Investors, Inc.,
a California corporation (the Managing General Partner), Calmark Investors,
Ltd., a California Limited Partnership (the Associate General Partner), and
Heritage Park II, Inc., a Delaware corporation (the Lehman General Partner).
 
  Allocations to Partners
 
     Income and Losses
 
     Income from operations is allocated pro rata to the General Partners and to
the Limited Partners as a class in the same ratio as cash distributions are made
to such partners (see below). In the event that no cash distributions are made
to the Partners during any year, income from operations shall be allocated 1% to
the General Partners and 99% to the Limited Partners.
 
     Losses from operations are generally allocated 1% to the General Partners
and 99% to the Limited Partners. Income from disposition or partial disposition
of Partnership property and income upon termination and liquidation of the
Partnership will be allocated as follows:
 
          a.  To Partners with negative adjusted capital account balances (as
              defined), after accounting for distributions described below, in
              proportion to their negative adjusted capital account balances.
 
          b.  Any remaining income will be allocated 5% to the Lehman General
              Partner, 25% to the Managing General Partner and Associate General
              Partner and 70% to the Limited Partners.
 
     Losses from disposition or partial disposition of the Partnership property
and all losses upon the termination and liquidation of the Partnership shall be
allocated as follows:
 
          a.  To all Partners with positive adjusted capital balances in
              proportion to their adjusted capital balances.
 
          b.  Any remaining losses will be allocated 1% to the General Partners
              and 99% to the Limited Partners.
 
     Cash Distributions
 
     Cash from operations is to be distributed, when available, not less often
than quarterly and not later than ninety days after the end of each fiscal
quarter of the Partnership in the following order of priority:
 
          a.  1% collectively to the Managing General Partner and the Associate
              General Partner and 99% to the Limited Partners as a class until
              such time as the Limited Partners have received in the aggregate
              an amount equal to a 10% per annum cumulative (but not compounded)
              return on their adjusted interest investment (as defined).
 
          b.  The remainder is allocated 25% collectively to the Managing
              General Partner and the Associate General Partner, 5% to the
              Lehman General Partner and 70% to the Limited Partners as a class.

                  CALMARK HERITAGE PARK II LIMITED PARTNERSHIP
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     In general, any proceeds remaining after the sale of the properties and
dissolution of the Partnership shall be distributed to the Partners in
accordance with their capital accounts.
 
  Investment Properties
 
     During 1995, the Partnership adopted FASB Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of ", which requires impairment losses to be recorded on long-lived assets used
in operations when indicators of impairment are present and the undiscounted
cash flows estimated to be generated by those assets are less than the assets'
carrying amount. The impairment loss is measured by comparing the fair value of
the asset to its carrying amount. The effect of adoption was not material.
 
  Depreciation
 
     Depreciation is provided by the straight-line method over the estimated
lives of the investment properties and related personal property.
 
  Loan Costs
 
     Loan costs are amortized on a straight-line basis over the lives of the
respective debt.
 
  Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage.
 
  Fair Value
 
     In 1995, the Partnership implemented Statement of Financial Accounting
Standards No. 107, "Disclosure about Fair Value of Financial Instruments", which
requires disclosure of fair value information about financial instruments for
which it is practicable to estimate that value. The carrying amount of the
Partnership's cash approximates fair value. The Partnership estimates the fair
value of its fixed rate mortgages by discounted cash flow analysis, based on
estimated borrowing rates currently available to the Partnership. The carrying
amounts of bonds payable approximate fair value due to frequent re-pricing (Note
2).
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.

  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2.  LONG-TERM DEBT
 
     Long-term debt at December 31, 1995 consists of the following:

Indebtedness under three 1992 Series A Bond Issues to
  various housing authorities bearing interest at variable
  rates, secured by first deeds of trust on the Anaheim,
  Escondido, and Livermore properties. Interest payments to
  the trustee are required semi-annually; the rate is reset
  every seven days and is to be that which would produce a
  par bid if the bonds were sold on the first day of the
  next seven-day reset period. The average annual interest
  rates for 1995 ranged from 2.55% to 5.75%. Two of the bond
  issues mature in 2007 and one in 2022; they can be
  redeemed prior to maturity without penalty, subject to
  certain provisions........................................    $22,905,000
Mortgage notes payable to various mortgage companies bearing
  interest at rates ranging from 9.78% to 11.125% per annum,
  secured by first deeds of trust on the Villa Serena, Las
  Vegas and Norco properties. These notes require monthly
  payments of principal and interest ranging from
  approximately $21,000 to $50,000, with balloon payments of
  $5,059,160 (Las Vegas) and $2,140,414 (Norco) due in April
  1996 and $3,823,999 (Villa Serena) due in November 2007...     12,402,711
Subordinated mortgage notes payable on the Anaheim,
  Livermore and Escondido properties. The Anaheim note in
  the amount of $600,000 bears interest at 10.525% and
  requires monthly interest payments of approximately
  $4,100. All unpaid interest plus the principal amount is
  due in 1997. The Livermore note in the amount of $100,000
  bears interest at 5% per annum and the interest and
  principal amounts are due in 2084. The Escondido note in
  the amount of $950,000 bears interest at 12% per annum,
  with monthly payments of 25% of net cash flow as defined,
  applied first to unpaid interest and then to, principal;
  any remaining unpaid principal and interest amounts are
  due in 1997...............................................      1,650,000
                                                                -----------
                                                                $36,957,711
                                                                ===========
</TABLE>
 
     The estimated fair values of the Partnership's aggregate debt is
$37,840,000, which represents a general approximation of possible value and is
not necessarily indicative of the amounts the Partnership may pay in actual
market transactions.
 
     The Partnership is required to make semi-annual payments to a Bond Fund
which can be used to redeem the 1992 Series A Bond Issues. Under the
requirements of the reimbursement agreement, the Partnership is required to make
payments of $300,000 (1996), $315,000 (1997), $335,000 (1998), $365,000 (1999)
and $390,000 (2000) to the Bond Fund which is held by the Trustee, First
Interstate Bank. During 1995, the Partnership redeemed bonds in the amount of
$300,000 with funds held in the Bond Fund.
 
     The Partnership has irrevocable letters of credit with First Interstate
Bank in the amounts of $8,979,959 (Anaheim), $7,546,850 (Escondido) and
$7,668,410 (Livermore), respectively. These letters of credit are additional
security for the 1992 Series A Bond Issues, and are secured by second deeds of
trust on the Anaheim, Escondido and Livermore properties. The Partnership is
required to pay monthly servicing fees of
 
                                      F-34

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
approximately 1% per annum, based on the outstanding amounts. The Partnership
also has a standby letter of credit in the amount of $8,979,959 which is
additional security for the Anaheim letter of credit.
 
     The Partnership is required to fund a Cash Collateral Account and Debt
Service Reserve Account, based on monthly net cash flow as defined, from these
three properties, up to a maxi mum of $1,200,000 and $400,000, respectively. The
Debt Service Reserve Account is to be funded from monthly net cash flow after
the Cash Collateral Account has been fully funded. These Accounts serve as
additional collateral for the bonds. At December 31, 1995, the balances in the
Cash Collateral Account and Debt Service Reserve were $1,153,788 and $-0-,
respectively.
 
     The Partnership has a money market account which is restricted as
additional collateral for the Las Vegas mortgage note payable. The balance in
this cash collateral account at December 31, 1995 was $109,407.
 
     The debt encumbering Las Vegas Apartments matures in April 1996. The
Partnership is currently negotiating a sale of the property with a potential
buyer, however, there is no assurance that the negotiations will ultimately be
successful.
 
     In January 1995, the Partnership went into default on the mortgage note
payable for Norco due to the Partnership only paying one-half of the required
monthly mortgage payment. The Partner ship made one-half of the required monthly
mortgage payment through April 1995, after which the Partnership made no
payments. As a result of the default, the Partnership is incurring default
interest on the mortgage note balance at the time of the event of default at
13.125%, or 2% above the stated rate. In December 1995, the rights of the
mortgage note payable were assigned to Praedium Chesapeake, LLC ("Praedium"). In
January 1996, Praedium served a notice of default and entered into an agreement
with the Partnership to execute a non-contested foreclosure on the Norco
property. The agreement provides for monthly excess cash flow payments until the
fore closure is complete. The balance outstanding on this mortgage note payable
was $2,158,334 at December 31, 1995.
 
     Principal maturities of long-term debt at December 31, 1995 are as follows:

3.  GROUND LEASES
 
     The Livermore property is subject to a ground lease that expires in
November 2084. The lease provides for rental payments of $5,000 per month. In
addition, the Partnership is required to pay annually the difference between the
minimum monthly rent described above and 4 1/2% of gross rental income from the
Livermore property for the preceding 12 months.
 
     The Norco property is subject to a ground lease which expires in June 2051.
The lease provides for annual rent of $35,000 through June 1996 at which time
the rent is subject to an increase or decrease based on changes in the consumer
price index within certain limitations. The rent is again subject to adjustment
on every fifth anniversary date thereafter, through the year 2051.

     During 1995, the Partnership ceased making payments on the Norco ground
lease, which constitutes an event of default. Ground lease payments totaling
$20,417 are accrued and included in other liabilities at December 31, 1995.
 
     Future minimum lease payments at December 31, 1995 are summarized as

4.  TRANSACTIONS WITH AFFILIATED PARTIES
 
     An affiliate of Insignia Financial Group, Inc. ("Insignia"), owns the
capital stock of the Managing General Partner with certain affiliates of
Insignia providing property management and asset management services to the
Partnership.
 
     The following payments were made to Insignia and its affiliates in 1995:

Property management fees................................    $334,527
Reimbursement for services of affiliates................      46,404
</TABLE>
 
     The Partnership insures its properties under a master policy through an
agency and insurer unaffiliated with the Managing General Partner. An affiliate
of the Managing General Partner acquired, in the acquisition of a business,
certain financial obligations from an insurance agency which was later acquired
by the agent who placed the current year's master policy. The current agent
assumed the financial obligations to the affiliate of the Managing General
Partner, who receives payments on these obligations from the agent. The amount
of the Partnership's insurance premiums accruing to the benefit of the affiliate
of the Managing General Partner by virtue of the agent's obligations is not
significant.
 
NOTE 5 -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   932
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the

Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Catawba Club Associates, L.P. For each unit that you tender, you may choose
     to receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").

<PAGE>   938
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $       per unit for the six months
     ended June 30, 1998 (equivalent to $       on an annual basis). We will pay
     fixed quarterly distributions of $       per unit on the Tax-Deferral
          % Preferred OP Units before any distributions are paid to holders of
     Tax-Deferral Common OP Units. We pay quarterly distributions on the
     Tax-Deferral Common OP Units based on our funds from operations for that
     quarter. For the six months ended June 30, 1998, we paid distributions of
     $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25 on
     an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.

Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
                                       S-4
<PAGE>   941
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   944
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   945
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   946
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   947
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   948
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not any own
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership has required funding from its partners. Continuation of its
     operations is dependent on additional funding from partners or from other
     sources. Your partnership faces maturity or balloon payment dates on its
     mortgage loans and must either obtain refinancing or sell its property. If
     your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your partnership without the
 
                                      S-12
<PAGE>   949
 
     offer would deny you and your partners the benefits that your general
     partner expects to result from the offer. For example, a partner of your
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

<PAGE>   951
 
     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   952
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units

unit.

Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $56,001 in 1996, $60,499 in 1997 and $28,649 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.

     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Catawba Club Associates, L.P. is a
Delaware limited partnership which was formed on May 28, 1985 for the purpose of
owning and operating a single apartment property located in Columbus, Ohio,
known as "Catawba Club Apartments". In 1985, it completed a private placement of
units that raised net proceeds of approximately $1,996,400. Catawba Club
Apartments consists of 186 apartment units. Your partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2008, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,661,438, payable to Marine Midland,
Bank of America and FNMA, which bears interest at a rate of 7.60%. The mortgage
debt is due in November 2002. Your partnership also has a second mortgage note
outstanding of $130,106, on the same terms as the first mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,

                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   963
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   964
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to
your units for the six months ended June 30, 1998 were $     per unit
(equivalent to $      on an annualized basis). This is equivalent to
distributions of $       per year on the number of Tax-Deferral   % Preferred
OP Units, or distributions of $ per year on the number of Tax-Deferral Common
OP Units, that you would receive in exchange for each of your partnerships
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   966
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership has required funding from its partners. Continuation of
its operations is dependent on additional funding from partners or from other
sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
                                      S-30
<PAGE>   967
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   969
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   970
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   972
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   974
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     partnership, its indebtedness or its operations which, in the sole judgment

     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   977
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the

Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   979
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   980
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   982
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   987
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   988
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value, the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   990
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   991
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $     per unit (equivalent to
     $     on an annualized basis). This is equivalent to distributions of
     $       per year on the number of Tax-Deferral   % Preferred OP Units, or
     distributions of $     per year on the number of Tax-Deferral Common OP
     Units, that you would receive in exchange for each of your partnerships
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   992
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Price............................................    $
Alternatives:
  Prices on Secondary Market................................    Not available

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
                                      S-57
<PAGE>   994
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
[October 1, 1998], when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in such capacity. The property manager
received management fees of $56,001 in 1996, $60,499 in 1997 and $28,649 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Catawba Club Associates, L.P. is a Delaware limited partnership which
raised net proceeds of approximately $1,996,400 in 1985 through a private
offering. The promoter for the private offering of your partnership was
Jacques-Miller. Insignia acquired your partnership in December 1991. AIMCO
acquired Insignia in October, 1998. There are currently a total of 45 limited
partners of your partnership and a total of 30.5 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 28, 1985 for the purpose of owning and
operating a single apartment property located in Columbus, Ohio, known as
"Catawba Club Apartments." Your partnership's property consists of 186 apartment
units. There are 51 one-bedroom apartments, 119 two-bedroom apartments and 16
three-bedroom apartments. The total rentable square footage of your
partnership's property is 178,246 square feet. Your partnership's property had
an average occupancy rate of approximately 87.63% in 1996 and 87.63% in 1997.
The average annual rent per apartment unit is approximately $6,029.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $56,001, $60,499 and $28,649, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2008
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,661,438, payable to Marine Midland, Bank of America and FNMA,
which bears interest at a rate of 7.60%. The mortgage debt is due in November
2002. Your partnership also has a second mortgage note outstanding of $130,106,
on the same terms as the first mortgage note. A third unsecured promissory note
payable to Jacques-Miller Income Fund II matured in November 1997, which bears
interest at a rate of 12.5%. Your partnership's agreement of limited partnership
also allows the general partner of your partnership to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Income
 
     Your partnership recognized net income of $14,550 for the six months ended
June 30, 1998, compared to $105,944 for the six months ended June 30, 1997. The
decrease in net income of $91,394, or 86.27% was primarily the result of a
decrease in rental revenues and an increase in operating expenses. These factors
are discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$576,570 for the six months ended June 30, 1998, compared to $601,406 for the
six months ended June 30, 1997, a decrease of $24,836, or 4.13%.
 
     Expenses

received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, property taxes and insurance, totaled
$284,781 for the six months ended June 30, 1998, compared to $217,629 for the
six months ended June 30, 1997, an increase of $67,152 or 30.86%. The increase
is due primarily to an increase in maintenance expenses and advertising costs to
improve the curb appeal of the property. Management expenses totaled $28,649 for
the six months ended June 30, 1998, compared to $31,186 for the six months ended
June 30, 1997, a decrease of $2,537, or 8.14%. The decrease resulted from a
decrease in rental revenues.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $22,508 for the six months
ended June 30, 1998 compared to $18,773 for the six months ended June 30, 1997,
an increase of $3,735 or 19.90%. The increase is primarily due to the timing of
asset management expense.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $145,388 for the six months ended June 30, 1998, compared to
$149,676 for the six months ended June 30, 1997, a decrease of $4,288, or 2.86%.

     Your partnership recognized net income of $38,586 for the year ended
December 31, 1997, compared to $206 for the year ended December 31, 1996. The
increase in net income of $38,380, was primarily the result of an increase in
rental revenues offset by an increase in operating expenses. These factors are
discussed in more detail in the following paragraphs.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $50,846 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
     The Partnership had debt that has matured in 1997 and due to Jacques Miller
Income Fund II totaling $413,606. This amount remains unpaid and the Company may
either refinance or negotiate the purchase of this note. However, there can be
no assurance that such a refinancing or negotiation will occur.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership is not
liable to your partnership or any limited partner for any acts or failures to do
any act performed by it of them in the absence of its willful malfeasance or
gross negligence. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership's agreement of limited partnership does not provide for
indemnification of the general partner by your partnership for any acts or
omissions performed by them.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partner of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The
original cost per unit was $39,928.

</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

     Skadden, Arps, Slate, Meagher & Flom LLP will deliver an opinion to the
effect that the Common OP Units and the Preferred OP Units offered by this
Prospectus Supplement will be validly issued, fully paid and nonassessable.
Skadden, Arps, Slate, Meagher & Flom LLP will deliver an opinion as to the
status of AIMCO as a REIT. Skadden, Arps, Slate, Meagher & Flom LLP has
previously performed certain legal services on behalf of AIMCO and the AIMCO
Operating Partnership and their affiliates.
 
     The opinion of Skadden, Arps, Slate, Meagher & Flom LLP is not attached to
this Prospectus Supplement. However, upon receipt of a written request by a
unitholder or representative so designated in writing, a copy of such opinion
will be sent by the Information Agent.
 
                                    EXPERTS
 
     The financial statements of Catawba Club Associates, L.P. at December 31,
1997 and 1996, appearing in this Prospectus Supplement have been audited by KPMG
Peat Marwick LLP, independent auditors, as set forth in their reports thereon
appearing elsewhere herein, and are included in reliance upon such reports given
upon the authority of such firm as experts in accounting and auditing. The
auditors' report dated February 23, 1998 refers to the fact that the partnership
is not generating sufficient cash flows to meet its maturing debt service
requirements, which raises substantial doubt about its ability to continue as a
going concern. Management's plans in regard to these matters are described in
the related footnotes. The financial statements do not include any adjustments
that might result from the outcome of that uncertainty.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Catawba Club Associates,
Limited as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with generally accepted accounting principles
for interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                           DECEMBER 31, 1997 AND 1996

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Catawba Club Associates, Limited:
 
     We have audited the accompanying balance sheets of Catawba Club Associates,
Limited as of December 31, 1997 and 1996 and the related statements of
operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Catawba Club Associates,
Limited as of December 31, 1997 and 1996, and the results of its operations and
its cash flows for the years then ended, in conformity with generally accepted
accounting principles.
 
     The accompanying financial statements have been prepared assuming that the
Partnership will continue as a going concern. As discussed in Note E to the
financial statements, the Partnership is not generating sufficient cash flows to
meet its maturing debt service requirements, which raises substantial doubt
about its ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note E. The accompanying financial
statements do not include any adjustments relating to the recoverability and
classification of recorded asset amounts or the amounts and classification of
liabilities that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Catawba Club Associates, Limited (the "Partnership") was organized as a
limited partnership under the laws of the State of Delaware pursuant to a
Limited Partnership Agreement and Certificate of Limited Partnership dated May
28, 1985. The Partnership owns and operates a 186 unit apartment complex,
Catawba Club Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets as depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$64,946 and $78,156, respectively, which are amortized over the term of the
related borrowing. Deferred loan costs are shown net of accumulated
amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.

refinancing is expected to occur during the second quarter of 1998; however,
there is not assurance that such a refinancing will occur.

     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid principal
balance at the time of prepayment or the present value of the excess of interest
which would be incurred at the stated rate under the notes over the interest
which would be incurred at the Treasury constant maturity for U.S. Government
obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership has no administrative or management employees and is
dependent on the Managing General Partner and its affiliates for the management
and administration of all partnership activities. The Partnership is obligated
to pay a property management fee equal to 5% of gross monthly collections. In
addition to the management fee, the partnership agreement provides for payments
to affiliates of a partnership administration fee and reimbursement of certain
expenses incurred by affiliates on behalf of the Partnership.
 
     Transactions with the Managing General Partner and its affiliates, in
addition to those disclosed in Note C, are as follows:

</TABLE>
 
NOTE E -- GOING CONCERN
 
     The General Partner is attempting to refinance the existing debt. The
General Partner believes that it will be successful, however there can be no
assurance that refinancing will be obtained.
 
     The Partnership is not generating sufficient cash flows to meet its
maturing debt service requirements, which raises substantial doubt about its
ability to continue as a going concern. The financial statements have been
prepared assuming that the Partnership will continue as a going concern and do
not include any adjustments that might result from these uncertainties.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Catawba Club Associates, Limited (the "Partnership") was organized as a
limited partnership under the laws of the State of Delaware pursuant to a
Limited Partnership Agreement and Certificate of Limited Partnership dated May
28, 1985. The Partnership owns and operates a 186 unit apartment complex,
Catawba Club Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 consist of deferred loan costs
which are amortized over the term of the related borrowing. Deferred loan costs
are shown net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended

     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1039
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Cedar Tree Investors Limited Partnership. For each unit that you tender,
     you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1044
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1045
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $2,640 per unit for the six months
     ended June 30, 1998 (equivalent to $5,280 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $     per year
     on the number of Tax-Deferral   % Preferred OP Units or distributions of
     $     per year on the number of Tax-Deferral Common OP Units that you would
     receive in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer considerations of $     consideration is
     fair. However, your units are not listed on any national securities
     exchange nor quoted on the NASDAQ System, and there is no established
     trading market for your units. Secondary sales activity for the units has
     been limited and sporadic. Your general partner does not monitor or
     regularly receive or maintain information regarding the prices at which
     secondary sale transactions in the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   1047
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly, you
might receive more value if you retain your units
 
                                       S-8
<PAGE>   1051
 
until your partnership is liquidated. However, you may prefer to receive the
offer consideration now rather than wait for uncertain future net liquidation
proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-9
<PAGE>   1052
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                      S-10
<PAGE>   1053
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-11
<PAGE>   1054
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-12
<PAGE>   1055
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently don't own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources. Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your
 
                                      S-13
<PAGE>   1056
 
     partnership without the offer would deny you and your partners the benefits
     that your general partner expects to result from the offer. For example, a
     partner of your partnership would have no opportunity for liquidity unless
     he were to sell his units in a private transaction. Any such sale would
     likely be at a very substantial discount from the partner's pro rata share
     of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax Deferral      % Preferred OP
       Units rank equal to six other outstanding classes of Partnership
       Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the

or Tax-Deferral      % Preferred OP Units, if necessary.
 
     Delivery of OP Units and Cash. We will deliver OP Units and cash as soon as

Information Agent in connection with the offer (the "Information Agent"). Its
telephone number is (888) 349-2005 or (201) 896-1900.
 
     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
                                      S-15
<PAGE>   1058
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to
 
                                      S-17
<PAGE>   1060
 
     Stanger is accurate in all material respects. You should make your decision
whether to tender based upon a number of factors, including your financial
needs, other financial opportunities available to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

view. The full text of the opinion, which contains a description of the

certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.

COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership, but may receive
reimbursement for expenses generated in that capacity from the partnership. The
property manager received management fees of $94,152 in 1996, $96,106 in 1997
and $52,073 for the first six months of 1998. We have no current intention of
changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Cedar Tree Investors Limited Partnership
is a Kansas limited partnership which was formed on June 14, 1991 for the
purpose of owning and operating a single apartment property located in Shawnee,
Kansas, known as Cedar Tree Apartments. In 1991, it completed a private
placement of units that raised net proceeds of approximately $2,550,000. Cedar
Tree Apartments consists of 344 apartment units. Your partnership has no
employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.

     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2021, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $4,622,405, payable to FNMA, which bears
interest at a rate of 6.43%. The mortgage debt is due in September, 2008. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-27
<PAGE>   1070
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-28
<PAGE>   1071
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June, 1998 were $2,640 per unit (equivalent to
$5,280 on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral   % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would received in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high level of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-30
<PAGE>   1073
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your Partnership may require funding from its partners. Continuation of
its operations may be dependent on additional funding from partners or from
other sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
                                      S-31
<PAGE>   1074
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.

     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   1077
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
 Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation
 to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole
 
                                      S-35
<PAGE>   1078
 
discretion, which determination shall be final and binding on all parties. The
AIMCO Operating Partnership reserves the absolute right to reject any or all
tenders of any particular unit determined by it not to be in proper form or if
the acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other
 
                                      S-36
<PAGE>   1079
 
person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, by increasing or decreasing the number of Preferred OP Units or
Common OP Units, or the amount of cash offered, eliminating any of the
alternative types of consideration being offered, or increasing or decreasing
the percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-37
<PAGE>   1080
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     been publicly disclosed or the AIMCO Operating Partnership shall have
     otherwise learned that (i) any person or group shall have acquired or
     proposed or be attempting to

     acquire beneficial ownership of more than four percent of the units, or
     shall have been granted any option, warrant or right, conditional or
     otherwise, to acquire beneficial ownership of more than four percent of the
     units, or (ii) any person or group shall have entered into a definitive
     agreement or an agreement in principle or made a proposal with respect to a
     merger, consolidation, purchase or lease of assets, debt refinancing or
     other business combination with or involving your partnership.
 
     The foregoing conditions are for the sole benefit of the AIMCO Operating
Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to your partnership's business, or that certain
parts of your partnership's business might not have to be disposed of or other
substantial conditions complied with in order to obtain such approval or action,
any of which could cause the
 
                                      S-41
<PAGE>   1084
 
     AIMCO Operating Partnership to elect to terminate the offer without
purchasing units hereunder. The AIMCO Operating Partnership's obligation to
purchase and pay for units is subject to certain conditions, including
conditions related to the legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts
 
                                      S-42
<PAGE>   1085
 
     distributable upon liquidation, dissolution or winding up in preference or
priority to the holders of such interest (the Common OP Units and such other
interests are collectively referred to herein as "Junior Units"); (ii) on a
parity with the Class B Partnership Preferred Units, the Class C Partnership
Preferred Units, the Class D Partnership Preferred Units, the Class G
Partnership Preferred Units, the Class H Partnership Preferred Units, and with
any other interest in the AIMCO Operating Partnership if the holders of such
interest and the Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in proportion to their respective amounts of accumulated, accrued and unpaid
distributions or stated preferences, without preference or priority of one over
the other ("Parity Units"); and (iii) junior to the Class F Partnership
Preferred Units and any other interest in the AIMCO Operating Partnership if the
holders of such interest shall be entitled to the receipt of distributions or
amounts distributable upon liquidation, dissolution or winding up in preference
or priority to the holders of the Preferred OP Units ("Senior Units"). Junior
Units, Parity Units and Senior Units may be issued from time to time by the
AIMCO Operating Partnership without any approval or consent by holders of the
Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for
 
                                      S-43
<PAGE>   1086
 
     such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.

<PAGE>   1087
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   1088
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46
<PAGE>   1089
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from

DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   1094
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   1095
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   1097
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-55
<PAGE>   1098
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the six months ended June, 1998 were $2,640 (equivalent to $5,280 on an
     annualized basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral   % Preferred OP Units, or distributions
     of $          per year on the number of Tax-Deferral Common OP Units, that
     you would receive in exchange for each of your partnership's units.
     Therefore, distributions with respect to the Preferred OP Units and Common
     OP Units that we are offering are expected to be        , immediately
     following our offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-56
<PAGE>   1099
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.

     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders.

     We determined the offer consideration, and Stanger did not, and was not
requested to, make any recommendations as to the form or amount of consideration
to be paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.

     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,

AIMCO concerning,
 
                                      S-60
<PAGE>   1103
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $94,152 in 1996, $96,106 in 1997 and $52,073 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Cedar Tree Investors Limited Partnership is a Kansas limited partnership
which raised net proceeds of approximately $2,550,000 in 1991 through a private
offering. The promoter for the private offering of your partnership was United
Investors Equity Services, Inc. Insignia acquired your partnership in December
1990. AIMCO acquired Insignia in October, 1998. There are currently a total of
67 limited partners of your partnership and a total of 75 units of your
partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
single apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on June 14, 1991 for the purpose of owning and
operating a single apartment property located in Shawnee, Kansas, known as
"Cedar Tree Apartments." Your partnership's property consists of 344 apartment
units. There are 199 one-bedroom apartments and 144 two-bedroom apartments. The
total rentable square footage of your partnership's property is 231,040 square
feet. Your partnership's property had an average occupancy rate of approximately
92.44% in 1996 and 92.44% in 1997. The average annual rent per apartment unit is
approximately $5,235.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $94,152, $96,106 and $52,073, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2021
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $4,622,405, payable to FNMA, which bears interest at a rate of
6.43%. The mortgage debt is due in September, 2008. Your partnership's agreement
of limited partnership also allows the general partner of your partnership to
lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

increase in net income of $102,058, or 73.90% was primarily the result of an
increase in rental revenues offset by an increase in operating expenses. These
factors are discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,033,496 for the six months ended June 30, 1998, compared to $905,675 for the

the six months ended June 30, 1997, an increase of $6,379, or 13.96%. The
increase resulted from an increase in rental revenues, as management fees are as
management fees are calculated based on a percentage of revenue.

     General and administrative expenses totaled $15,276 for the six months
ended June 30, 1998 compared to $15,973 for the six months ended June 30, 1997,

31, 1996
 
     Net Income

year ended December 31, 1996, compared to $796,744 for the year ended December
31, 1995, a decrease of $47,920 or 6.01%. The decrease is primarily due to a
decrease in maintenance expenses due to an extensive exterior painting project
at the property in the fourth quarter of 1995. Management expenses totaled
$94,152 for the year ended December 31, 1996, compared to $91,253 for the year

Operating. Grouped the same way as in 1995, 1996 General and Administrative
expense would be $65,555.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the doing of any act or the failure to do any
act by the general partner, which does not constitute fraud, gross negligence or
willful malfeasance as determined a court of competent jurisdiction, in
pursuance of the authority granted to promote the interests of your partnership,
the effect of which causes or results in loss or damage to your partnership, if
done in good faith, will not subject the general partner or its affiliates to
any liability. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will indemnify and hold harmless the general partners and
their affiliates from any claim, loss, expense, liability, action or damage
resulting from any act or omission done in good faith which does not constitute
fraud, gross negligence or willful malfeasance as determined by a court of
competent jurisdiction, in pursuance of the authority granted to promote the
interests of your partnership, including, without limitation, reasonable fees
and expenses of attorneys engaged by the general partner in defense of such act
or omission and other reasonable costs and expenses of litigation and appeal.
All costs and expenses incurred in defending any proceeding or action or
otherwise will be advanced by your partnership. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Cedar Tree Investors
Limited Partnership (a Kansas Limited Partnership) as of June 30, 1998 and for
the six months ended June 30, 1998 and 1997 have been prepared in accordance
with generally accepted accounting principles for interim financial information.
Accordingly, they do not include all the information and footnotes required by
generally accepted accounting principles for complete financial statements. In
the opinion of management, all adjustments considered necessary for a fair
presentation have been included and all such adjustments are of a recurring
nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Cedar Tree Investors Limited Partnership
(A Kansas Limited Partnership):
 
     We have audited the accompanying balance sheet of Cedar Tree Investors
Limited Partnership (a Kansas Limited Partnership) (the "Partnership") as of
December 31, 1997, and the related statements of operations, changes in
partners' capital (deficit), and cash flows for each of the two years in the
period ended December 31, 1997. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Partnership as of December 31, 1997, and
the results of its operations and its cash flows for each of the two years in
the period ended December 31, 1997 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1997 AND 1996
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Cedar Tree Investors Limited Partnership (a Kansas Limited Partnership)
(the "Partnership") was formed to acquire, own and operate Cedar Tree
Apartments, a 344-unit multifamily residential complex located in Shawnee,
Kansas. The general partner of the Partnership is United Investors Real Estate,
Inc., a Delaware corporation.
 
  Basis of Accounting
 
     The accompanying financial statements of the Partnership are prepared on
the accrual basis and, therefore, revenue is recorded as earned and costs and
expenses are recorded as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash
 
     Cash and cash equivalents includes cash on hand and in banks, money market
funds and certificates of deposit with original maturities of less than three
months.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the leases and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Income Taxes
 
     For income tax purposes, the Partnership reports revenue and costs and
expenses on the accrual method. No income tax provisions have been shown in the
accompanying statements of operations since the partners are taxed individually.
 
  Investment Properties
 
     Investment properties are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over estimated useful
lives of 15 to 40 years for buildings and improvements and 5 to 12 years for
furniture and fixtures.
 
     The Partnership records impairment losses on long-lived assets used in
operations when events and circumstances indicate that the assets might be
impaired and the undiscounted cash flows estimated to be generated by those
assets are less than the carrying amounts of those assets.
 
  Other Assets
 
     Included in other assets are deferred charges which consist of loan costs
totaling $153,506 which are amortized over the term of the related note.
Accumulated amortization as of December 31, 1997 was $98,532.

  Advertising
 
     The Partnership expenses the cost of advertising as incurred. Advertising
expense, included in operating expenses, was $48,608 and $25,589 for the years
ended December 31, 1997 and 1996, respectively.
 
  Reclassifications
 
     Certain reclassifications of prior year balances have been made to conform
to the current year's presentation.
 
2.  MORTGAGE NOTE PAYABLE
 
     The mortgage note payable consists of a 10-year nonrecourse note
collateralized by Cedar Tree Apartments, payable in monthly installments of
$41,944, including interest. The interest rate is fixed at 9.75% per year. The
mortgage note payable matures on September 1, 2001. Scheduled maturities of
principal are as follows:

                         NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1996 AND 1995
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Cedar Tree Investors Limited Partnership (A Kansas Limited Partnership)
(the "Partnership") was formed to acquire, own and operate Cedar Tree
Apartments, a 344-unit multifamily residential complex located in Shawnee,
Kansas. The general partner of the Partnership is United Investors Real Estate,
Inc., a Delaware corporation.
 
  Basis of Accounting
 
     The accompanying financial statements of the Partnership are prepared on
the accrual basis and, therefore, revenue is recorded as earned and costs and
expenses are recorded as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash
 
     Cash and cash equivalents includes cash on hand and in banks, money market
funds and certificates of deposit with original maturities of less than three
months.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are considered restricted cash. Deposits are
refunded when the tenant vacates, provided the tenant has not damaged its space
and is current on its rental payments.
 
  Income Taxes
 
     For income tax purposes, the Partnership reports revenue and costs and
expenses on the accrual method. No income tax provisions have been shown in the
accompanying statements of operations since the partners are taxed individually.
 
  Apartment Properties
 
     Apartment properties are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over estimated useful
lives of 15 to 40 years for buildings and improvements and 5 to 12 years for
furniture and fixtures.
 
     During 1995, the Partnership adopted Statement of Financial Accounting
Standards ("SFAS") No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of, which requires impairment losses to
be recognized for long-lived assets used in operations when indicators of
impairment are present and the undiscounted cash flows are not sufficient to
recover the assets' carrying amounts. The impairment loss is measured by
comparing the fair value of the asset to its carrying amount. The adoption of
SFAS No. 121 had no effect on the Partnership's financial statements.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Deferred Charges
 
     Deferred charges consist of loan costs which are amortized over the term of
the related note.
 
  Advertising
 
     The Partnership expenses the cost of advertising as incurred. Advertising
expense, included in operating expenses, was $25,589 and $18,647 for the years
ended December 31, 1996 and 1995, respectively.
 
  Reclassifications
 
     Certain reclassifications of prior year balances have been made to conform
to the current year's presentation.
 
2.  MORTGAGE NOTE PAYABLE
 
     The mortgage note payable consists of a 30-year nonrecourse note
collateralized by Cedar Tree Apartments, payable in monthly installments of
$41,944, including interest. The interest rate is fixed at 9.75% per year.
Scheduled maturities of principal are as follows:

3.  PARTNERS' EQUITY
 
  Allocations of Profits and Losses
 
     In accordance with the partnership agreement, all profits and losses are to
be allocated 1% to the general partner and 99% to the limited partners.
 
  Distributions
 
     The Partnership allocates distributions 1% to the general partner and 99%
to the limited partners. Subsequent to December 31, 1996, the Partnership paid a
distribution to the partners of $101,000 on February 18, 1997.
 
4.  RELATED PARTY TRANSACTIONS
 
     During the years ended December 31, 1996 and 1995, the Partnership paid the
following amounts to affiliates of the general partner:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     In addition, affiliates of the general partner were paid $6,537 and $20,256
during 1996 and 1995, respectively, for construction oversight costs incurred in
conjunction with the Partnership's capital improvement and major repair
projects.
 
     The Partnership insures Cedar Tree Apartments under a master policy through
an agency and insurer unaffiliated with the general partner. An affiliate of the
general partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the general partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the general partner by
virtue of the agent's obligations is not significant.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Cedar Tree Investors Limited Partnership
(A Kansas Limited Partnership)
 
     We have audited the accompanying balance sheet of Cedar Tree Investors
Limited Partnership (A Kansas Limited Partnership) (the "Partnership") as of
December 31, 1995, and the related statements of operations, changes in
partners' capital (deficit), and cash flows for each of the two years in the
period ended December 31, 1995. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Partnership as of December 31, 1995, and
the results of its operations and its cash flows for each of the two years in
the period ended December 31, 1995 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1995 AND 1994
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Cedar Tree Investors Limited Partnership (A Kansas Limited Partnership) was
formed to acquire, own and operate Cedar Tree Apartments, a 344-unit multifamily
residential complex located in Shawnee, Kansas. The general partner of the
Partnership is United Investors Real Estate, Inc., a Delaware corporation.
 
  Basis of Accounting
 
     The accompanying financial statements of the Partnership are prepared on
the accrual basis and, therefore, revenue is recorded as earned and costs and
expenses are recorded as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash
 
     Cash and cash equivalents includes cash on hand and in banks, money market
funds and certificates of deposit with original maturities of less than three
months.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are considered restricted cash. Deposits are
refunded when the tenant vacates, provided the tenant has not damaged its space
and is current on its rental payments.
 
  Income Taxes
 
     For income tax purposes, the Partnership reports revenue and costs and
expenses on the accrual method. No income tax provisions have been shown in the
accompanying statements of operations since the partners are taxed in their
individual capacities.
 
  Apartment Properties
 
     Apartment properties are stated at cost less accumulated depreciation.
Depreciation is computed using straight-line methods over estimated useful lives
of 15 to 40 years for buildings and improvements and 5 to 12 years for furniture
and fixtures.
 
     During 1995, the Partnership adopted FASB Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of," which requires impairment losses to be recognized for long-lived assets
used in operations when indicators of impairment are present and the
undiscounted cash flows are not sufficient to recover the assets' carrying
amounts. The impairment loss is measured by comparing the fair value of the
asset to its carrying amount. The adoption of FASB No. 121 had no effect on the
Partnership's financial statements.
 
  Deferred Charges
 
     Deferred charges consist of loan costs which are amortized over the terms
of the related notes.

  Advertising
 
     The Partnership expenses the cost of advertising as incurred. Advertising
expense, included in operating expenses, was $18,647 and $17,759 for the years
ended December 31, 1995 and 1994, respectively.
 
  Fair Value
 
     In 1995, the Partnership implemented Statement of Financial Accounting
Standards No. 107, "Disclosure about Fair Value of Financial Instruments," which
requires disclosure of fair value information about financial instruments for
which it is practicable to estimate that value. The carrying amount of the
Partnership's cash and cash equivalents approximates fair value due to
short-term maturities. The Partnership estimates the fair value of its fixed
rate mortgages by discounted cash flow analysis, based on estimated borrowing
rates currently available to the Partnership.
 
  Reclassifications
 
     Certain reclassifications of prior year balances have been made to conform
to the current year presentation.
 
2.  MORTGAGE NOTE PAYABLE
 
     The mortgage note payable consists of a 10-year nonrecourse note
collateralized by Cedar Tree Apartments, payable in monthly installments of
$41,944, including interest. The interest rate is fixed at 9.75% per year.
Scheduled maturities of principal are as follows:

     The estimated fair value of the Partnership's aggregate debt is
approximately $5.1 million. This value represents a general approximation of
possible value and is not necessarily indicative of the amounts the Partnership
may pay in actual market transactions.

be allocated 1% to the general partner and 99% to the limited partners.
 
  Distributions
 
     The Partnership allocates distributions 1% to the general partner and 99%

     During the years ended December 31, 1995 and 1994, the Partnership paid the
following amounts to affiliates of the general partner:

Property management fees.................................  $91,253    $87,451
Reimbursement of expenses................................   15,000     10,000
</TABLE>
 
     The Partnership insures Cedar Tree Apartments under a master policy through
an agency and insurer unaffiliated with the general partner. An affiliate of the
general partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the general partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the general partner by
virtue of the agent's obligations is not significant.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   1155
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1156
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Chapel Hill, Limited. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1161
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1162
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of year tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0 per unit for the six months ended
     June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   1164
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1167
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   1168
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   1169
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   1170
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   1171
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 3.85% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   1172
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.

     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

<PAGE>   1174
 
     - terminate the offer and not accept for payment any units not theretofore

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF

     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND "FEDERAL INCOME TAXATION
OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME TAXATION OF THE AIMCO
OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX CONSEQUENCES" IN THE
ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING
OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness
 
                                      S-16
<PAGE>   1176
 
     to you of our offer consideration. Stanger is not affiliated with us or
your general partner. Stanger is one of the leaders in the field of analyzing
and evaluating complex real estate transactions. However, we provided much of
the information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. You should
make your decision whether to tender based upon a number of factors, including
your financial needs, other financial opportunities available to you and your
tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.

<PAGE>   1177
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $48,000
annually of your partnership and may also receive reimbursement for expenses
generated in its capacity as general partner. The property manager received
management fees of $116,896 in 1996, $119,469 in 1997 and $61,949 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Chapel Hill, Limited is a Tennessee
limited partnership which was formed on April 20, 1984 for the purpose of owning
and operating a small number of apartment properties located in Indianapolis,
Indiana, known as "Chapel Hill Apartments" and "Chapelwood Apartments." In 1984,
it completed a private placement of units that raised net proceeds of
approximately $4,888,000. Chapel Hill Apartments consists of 148 apartment units
and Chapelwood Apartments consists of 140 apartment units. Your partnership has
no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase
 
                                      S-18
<PAGE>   1178
 
of equipment and supplies, and the selection and engagement of all vendors,
suppliers and independent contractors. The property manager is affiliated with
us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on July 1, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding on Chapel Hill Apartments of $3,511,739,
payable to Marine Midland Bank, Bank of America and FNMA, which bears interest
at a rate of 7.60%. Such mortgage debt is due November 2002. Your partnership
also has a second mortgage note outstanding on the property of $124,785, on the
same terms as the current Chapel Hill Apartments mortgage note. There is also a
mortgage note on Chapelwood Apartments, the balance of which is $3,638,777, as
of June 30, 1998. The note is payable to Marine Midland Bank, Bank of America
and FNMA, bears interest at 7.60% and is due November 2002. Chapelwood
Apartments also secures a second mortgage note with a balance of $129,300 which
has the same terms as the first mortgage. Your partnership's agreement of
limited partnership also allows your general partner to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

            SUMMARY FINANCIAL INFORMATION OF AIMCO PROPERTIES, L.P.
 
     The historical summary financial data for AIMCO Properties, L.P. for the
six months ended June 30, 1998 and 1997 is unaudited. The historical summary
financial data for AIMCO Properties, L.P. for the years ended December 31, 1997,

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1186
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1187
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of $0
with respect to your units, distributions with respect to the Preferred OP Units
and Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   1188
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 3.85% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   1189
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral
 
                                      S-30
<PAGE>   1190
 
       % Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units. Your Partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1192
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1193
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   1194
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   1195
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.

     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     time of the commencement of the offer, in the sole judgment of the AIMCO

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   1200
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   1201
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-42
<PAGE>   1202
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the

and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations

     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   1205
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   1210
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   1211
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .

     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   1214
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions with respect to
     the Common OP Units of $2.25, and the 1998 distributions of $0 with respect
     to your units, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   1215
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   1216
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not
                                      S-58
<PAGE>   1218
 
     limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the
                                      S-59
<PAGE>   1219
 
     value of the partnership's property or other balance sheet assets and
liabilities or other information reviewed between the date of such information
provided and the date of the Fairness Opinion; that your partnership, AIMCO, and
the management of the partnership's property are not aware of any information or
facts that would cause the information supplied to Stanger to be incomplete or
misleading; that the highest and best use of the partnership's property is as
improved; and that all calculations were made in accordance with the terms of
your partnership's agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the

Federal securities laws. No portion of Stanger's fee is contingent upon
consummation of the offer or the content of Stanger's opinion. Stanger has

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer consideration for you, even as a subsidiary of AIMCO. It also has a
duty to remove the property manager for your partnership's property, under
certain circumstances, even though the property manager is also an affiliate of
AIMCO. The conflicts of interest include the fact that a decision to remove, for
any reason, the general partner of your partnership from its current position as
a general partner of your partnership would result in a decrease or elimination
of the substantial management fees paid to an affiliate of the general partner
of your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $48,000
annually from your partnership and may receive reimbursement for expenses
generated in its capacity as general partner. The Property Manager received
management fees of $116,896 in 1996, $119,469 in 1997 and $61,949 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Your partnership is a Tennessee limited partnership which raised net
proceeds of approximately $4,888,000 in 1984 through a private offering. The
promoter for the private offering of your partnership was Freeman Properties,
Inc. Insignia acquired your partnership in December 1991. AIMCO acquired
Insignia in October, 1998. There are currently a total of 74 limited partners of
your partnership and a total of 65 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the small number of apartment
properties described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on April 20, 1984 for the purpose of owning and
operating a small number of apartment properties located in Indianapolis,
Indiana, known as "Chapel Hill Apartments" and "Chapelwood Apartments". There
are 148 apartment units in Chapel Hill Apartments consisting of 28 one-bedroom
apartments, 80 two-bedroom apartments and 40 three-bedroom apartments. The total
rentable square footage is 183,600 square feet and the average annual rent per
apartment unit is $7,174. Chapel Hill Apartments had an average occupancy rate
of 95.27% in 1996 and 1997. Chapelwood Apartments has 140 apartment units. There
are 24 one-bedroom apartments, 32 two-bedroom apartments and 68 three-bedroom
apartments. The total rentable square footage is 220,300 square feet. In 1996,
Chapelwood Apartments had an average occupancy rate of approximately of 90.71%
and 90.71% in 1997. The average annual rent per apartment unit is $8,566.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all

INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on July 1, 2015 unless
earlier dissolved. Your partnership has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.

     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,511,739, payable to Marine Midland Bank, Bank of America and

partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
financial statements of your partnership included herein.

June 30, 1997

30, 1997. The decrease in net income of $162,701, or 144.81% was primarily the
result of an increase in operating expenses during 1998. These factors are
discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,231,112 for the six months ended June 30, 1998, compared to $1,181,549 for

received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, property taxes and insurance, totaled
$576,703 for the six months ended June 30, 1998, compared to $423,632 for the
six months ended June 30, 1997, an increase of $153,071 or 36.13%. The increase
is primarily due to an increase in accrued expenses for the interim period and
an increase in repairs and maintenance at both properties. Management expenses
totaled $61,949 for the six months ended June 30, 1998, compared to $59,112 for
the six months ended June 30, 1997, an increase of $2,837, or 4.80%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $53,903 for the six months
ended June 30, 1998 compared to $40,293 for the six months ended June 30, 1997,
an increase of $13,610 or 33.78%. The increase is primarily due to the timing of
audit fees.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $283,932 for the six months ended June 30, 1998, compared to
$292,305 for the six months ended June 30, 1997, $8,534 for the six months ended

December 31, 1996. The increase in net income of $76,397, or 53.88% was
primarily the result of an increase in rental revenues and a decrease in
property taxes offset by an increase in operating expenses. These factors are
discussed in more detail in the following paragraphs.

project at one of the properties in 1995. Management expenses totaled $116,896
for the year ended December 31, 1996, compared to $115,300 for the year ended

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $347,599 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable, in damages or
otherwise to your partnership or any limited partner for any acts performed by
any of them which are reasonably believed by them to be within the scope of the
authority conferred on them by your partnership's agreement of limited
partnership, excepting only acts of malfeasance, gross negligence or actual
misrepresentation. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest."
 
     The general partner and its affiliates are entitled to indemnification by
your partnership for any and all acts performed by them in the good faith belief
that the act or omission was in the best interests of your partnership and which
are reasonably within the scope of the authority conferred upon them by your
partnership's agreement of limited partnership or by your partnership, excepting
only acts of malfeasance, gross negligence or actual misrepresentation;
provided, however, that such indemnity will be paid out of and only to the
extent of partnership assets. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not made a distribution within the last five years.
The original cost per unit was $65,173.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer

necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

        (UNAUDITED -- SEE ACCOMPANYING ACCOUNTANTS' COMPILATION REPORT)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Chapel Hill, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated January 24,
1975. The Partnership owns and operates Chapel Woods Townhouses a 140 townhouse
complex, and Chapel Hill Apartments, a 148 unit apartment complex, both located
in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Davidson Properties, Inc., an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded, as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$121,706 and $146,355, respectively, which are amortized over the term of the
related borrowing. They are shown net of accumulated amortization. Also included
in other assets are syndication costs of $336,142 which are not amortized.

        (UNAUDITED -- SEE ACCOMPANYING ACCOUNTANTS' COMPILATION REPORT)
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1996 AND 1995
        (UNAUDITED -- SEE ACCOMPANYING ACCOUNTANTS' COMPILATION REPORT)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Chapel Hill, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated January 24,
1975. The Partnerships owns and operates Chapel Woods Townhouses a 140 townhouse
complex, and Chapel Hill Apartments, a 148 unit apartment complex, both located
in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Davidson Properties, Inc., an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1996 include deferred loan costs which are
amortized over the term of the related borrowing. They are shown net of
accumulated amortization. Also included in other assets are utility deposits and
syndication costs which are not amortized.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
                                       A-1
<PAGE>   1258
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1259
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Chestnut Hill Associates Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
                                       S-1
<PAGE>   1264
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions
 
                                       S-2
<PAGE>   1265
 
      paid on the Tax-Deferral Common OP Units have been equivalent to the
      dividends paid on AIMCO's Class A Common Stock. We expect this to continue
      in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $4,000 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $
     per year on the number of Tax-Deferral   % Preferred OP Units or
     distributions of $     per year on the number of Tax-Deferral Common OP
     Units that you would receive in an exchange for each of your partnership's
     units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL

<PAGE>   1266
 
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general

Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1270
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   1271
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   1272
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   1273
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   1274
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 22.25% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   1275
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Preferred OP Units has prior
       distribution rights and the Tax-Deferral   % Preferred OP Units rank
       equal to six other outstanding classes of Preferred OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

<PAGE>   1277
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we
 
                                      S-16
<PAGE>   1279
 
provided much of the information used by Stanger in forming its fairness
opinion. We believe the information provided to Stanger is accurate in all
material respects. You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, the general partner is entitled to compensation for its services
as general partner while the general partner of the AIMCO Operating Partnership
is not entitled to any fees.

<PAGE>   1280
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. Your partnership's agreement of limited partnership
provides that the general partner of your partnership receives a cumulative
annual fee of $75,000 increased by 6% per annum, compounded annually, from your
partnership and may also receive reimbursement for expenses generated in its
capacity as general partner. The property manager received management fees of
$248,814 in 1996, $301,301 in 1997 and $231,420 for the first six months of
1998. We have no current intention of changing the fee structure for your
property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Chestnut Hill Associates Limited
Partnership is a Delaware limited partnership which was formed on July 21, 1986
for the purpose of owning and operating a single apartment property located in
Philadelphia, Pennsylvania, known as "Chestnut Hill Village." Chestnut Hill
Village consists of 830 apartment units. Your partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors.

<PAGE>   1281
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2036, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $26,203,796, payable to Chase Manhattan
Bank, which bears interest at a rate of 8.38%. The mortgage debt is due in
January 2007. Your partnership's agreement of limited partnership also allows
your general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1289
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1290
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the year ended December 31, 1997 were $4,000 per unit. This is
equivalent to distributions of $     per year on the number of Tax-Deferral   %
Preferred OP Units, or distributions of $     per year on the number of
Tax-Deferral Common OP Units, that you would receive in an exchange for each of
your partnership's units. Therefore, distributions with respect to the Preferred
OP Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 22.25% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   1292
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   1293
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to five other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1295
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1296
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   1297
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   1298
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of considerations being offered, or increasing or decreasing the
percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   1300
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory
 
                                      S-40
<PAGE>   1303
 
permits that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class E
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
 
                                      S-42
<PAGE>   1305
 
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
 
                                      S-43
<PAGE>   1306
 
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership
 
                                      S-45
<PAGE>   1308
 
will not then or in the future jeopardize AIMCO's status as a REIT. As a
condition of such waiver, the AIMCO board of directors may require opinions of
counsel satisfactory to it and/or an undertaking from the applicant with respect
to preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   1313
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   1314
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53

     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   1317
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the year ended December 31, 1997 were $4,000. This is equivalent to
     distributions of $     per year on the number of Tax-Deferral   % Preferred
     OP Units, or distributions of $     per year on the number of Tax-Deferral
     Common OP Units, that you would receive in exchange for each of your
     partnership's units. Therefore, distributions with respect to the Preferred
     OP Units and Common OP Units that we are offering are expected to be
            , immediately following our offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   1318
 
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment properties although there are
other ways to value real estate. A liquidation in the future might generate a
higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
 
                                      S-59

AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives a
cumulative annual fee of $75,000 in 1986, increasing by 6% per annum from your
partnership. The property manager received management fees of $248,814 in 1996,
$301,301 in 1997 and $231,420 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Chestnut Hill Associates Limited Partnership is a Delaware limited
partnership. Insignia acquired your partnership in November 1997. AIMCO acquired
Insignia in October, 1998. There are currently a total of 194 limited partners
of your partnership and a total of 250 units of your partnership outstanding.
Your partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on July 21, 1986 for the purpose of owning and
operating a single apartment property located in Philadelphia, Pennsylvania,
known as "Chestnut Hill Village." Your partnership's property consists of 830
apartment units. There are 478 one-bedroom apartments, 307 two-bedroom
apartments and 36 three-bedroom apartments. The total rentable square footage of
your partnership's property is 821,141 square feet. The average annual rent per
apartment unit is approximately $8,644.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $248,814, $301,301 and $231,420, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2036
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All
 
                                      S-71
<PAGE>   1334
 
capital improvement and renovation costs are expected to be paid from operating
cash flows, cash reserves, or from short-term or long-term borrowings. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $26,203,796, payable to Chase Manhattan Bank, which bears
interest at a rate of 8.38%. The mortgage debt is due in January 2007. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

result of increased revenues. These factors are discussed in more detail in the
following paragraphs.

equivalents. Your partnership's principal demands for liquidity include normal

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable, in damages or
otherwise to your partnership or any limited partner for any acts performed or
any failure to act by any of them if they determined, in good faith, that such
act or failure to act was in the best interests of your partnership and such
course of conduct did not constitute negligence or misconduct on the part of the
general partner. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss, damage, liability, cost or expense incurred
by them in connection with your partnership, provided that such loss, damage,
liability, cost or expense was not the result of negligence or misconduct of any
such entity provided, however, that such indemnity will be paid out of and only
to the extent of Partnership assets. Neither the general partner, any of its
affiliates nor any placing brokers will be indemnified for any loss, damage or
cost resulting from the violation of any Federal or state securities law unless
either (a) either (1) there has been a successful adjudication on the merits of
each count involving such securities law violations, (2) such claims have been
dismissed with prejudice on the merits by a court of competent jurisdiction or
(3) a court of competent jurisdiction approves such a settlement and (b) a court
either (1) approves the settlement and finds that indemnification of the
settlement and related costs should be made or (2) approves indemnification of
litigation costs if a successful defense is made. In such claim for
indemnification for Federal or state securities law violation, the party seeking
indemnification must place before the court the position of the SEC and any
other applicable regulatory agency with respect of the issue of indemnification
for securities law violations. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     Your partnership will not incur the cost of the portion of any insurance
which insures any party against any liabilities as to which such part is
prohibited from being indemnified under your partnership's agreement of limited
partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or
 
                                      S-76
<PAGE>   1339
 
maintain information regarding the prices at which secondary sale transactions
in the units have been effectuated. The general partner of your partnership
estimates, based solely on the transfer records of your partnership (or your
partnership's transfer agent), that there have been no units transferred in sale
transactions (excluding transactions believed to be between related parties,
family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     AIMCO currently owns a 22.25% limited partnership interest in your
partnership. Except as described above, neither AIMCO, nor, to the best of its
knowledge, any of its affiliates, (i) beneficially own or have a right to
acquire any units, (ii) have effected any transaction in the units, or (iii)
have any contract, arrangement, understanding or relationship with any other
person with respect to any securities of your partnership, including, but not
limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) management fees in its capacity as general partner

as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Chestnut Hill Associates
Limited Partnership as of June 30, 1998 and for the six months ended June 30,
1998 have been prepared in accordance with generally accepted accounting
principles for interim financial information. Accordingly, they do not include
all the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments considered necessary for a fair presentation have been included and
all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
Chestnut Hill Associates Limited Partnership
 
     We have audited the accompanying balance sheets of Chestnut Hill Associates
Limited Partnership, a Delaware limited partnership, as of December 31, 1997 and
1996, and the related statements of operations, partners' equity and cash flows
for the years then ended. These financial statements are the responsibility of
the Partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Chestnut Hill Associates
Limited Partnership as of December 31, 1997 and 1996, and the results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Chestnut Hill Associates Limited Partnership, a Delaware limited
partnership, was formed in July 1986 to acquire, renovate and operate an
apartment complex known as Chestnut Hill (the "Property"). The Property consists
of an 830-unit garden apartment and townhouse development located on 31.2 acres
of land in Philadelphia, Pennsylvania. The Partnership will terminate on
December 31, 2036, or earlier upon the occurrence of certain events specified in
the Partnership Agreement. The general partner of the Partnership was Winthrop
Financial Associates. A Limited Partnership, a Maryland Limited Partnership
("WFA"). The initial limited partners of the Partnership were The Winthrop
Properties, Inc. and WFA.
 
     Prior to December 16, 1996 profits and losses from normal operations were
allocated 7% to WFA and 93% to the Investor Limited Partners. Cash flow from
operations were allocated 3% to WFA and 97% to the Investor Limited Partners.
 
     Effective December 16, 1996, WFA withdrew from the partnership as the
general partner and assigned 1% of 7% interest to the new general partner, CHA
Properties, Inc. ("CHA"). WFA retained its remaining 6% interest which was
converted to a limited partnership interest but is not considered an investor
limited partner. Profits, losses and distributions of the partnership are
allocated 1% to the general partner, 6% to WFA and 93% to the investor limited
partners.
 
  Basis of Presentation
 
     The partnership prepares its financial statements on the accrual basis of
accounting.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. The Partnership depreciates
the property on the straight-line method over their estimated useful lives for
financial statement purposes. For income tax purposes, accelerated methods and
lives are used.
 
  Amortization
 
     Mortgage costs are amortized over the term of the mortgage loan using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for federal, state or local income taxes in the
financial statements of the Partnership. The Partners are required to report on
their individual income tax returns their allocable share of income, gains,
losses, deductions and credits of the Partnership. The Partnership files its own
tax return on the accrual basis.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the Partnership and
tenants of the property are operating leases.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For the purpose of the statement of cash flows, the partnership considers
all highly liquid investments to be cash equivalents. The carrying amount in
1997 of $2,059,961 and in 1996 of $3,873,025 approximates fair value because of
the short maturity of this instrument.

the Partnership is required to develop, implement and carry out an operations
and maintenance plan for "Lead Based Paint" on the Property ("O & M Plan"). The
"O & M Plan" requires that in event the Partnership desires to make renovations
to or demolish the Property or any portion, thereof, the Partnership is required
to have all painted surfaces (including all underlying paint layers) at the
Property that are being renovated or demolished tested for the presence of Lead

presence of Lead Based Paint at the Property, the Partnership is required at
their expense, to remove all Lead Based Paint in accordance with all applicable
local, state and federal laws.
 
  Asbestos Operations and Maintenance Agreement
 
     As a condition of making the loan, the Partnership has agreed to develop an
operations and maintenance program for the Property with respect to the presence
of asbestos (the "O & M Program"). The Operations and Maintenance Program has

1995, and the related statements of operations, partners' equity and cash flows
for the years then ended. These financial statements are the responsibility of
the Partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Chestnut Hill Associates
Limited Partnership as of December 31, 1996 and 1995, and the results of its

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Chestnut Hill Associates Limited Partnership, a Delaware limited
partnership, was formed in July 1986 to acquire, renovate and operate an
apartment complex known as Chestnut Hill (the "Property"). The Property consists
of an 830-unit garden apartment and townhouse development located on 31.2 acres
of land in Philadelphia, Pennsylvania. The Partnership will terminate on
December 31, 2036, or earlier upon the occurrence of certain events specified in
the Partnership Agreement. The general partner of the Partnership was Winthrop
Financial Associates, a Limited Partnership, a Maryland Limited Partnership
("WFA"). The initial limited partners of the Partnership were Three Winthrop
Properties, Inc. and WFA.
 
     Profits and losses from normal operations were allocated 7% to WFA and 93%
to the Investor Limited Partners. Cash flow from operations were allocated 3% to
WFA and 97% to the Investor Limited Partners.
 
     Effective December 16, 1996, WFA withdrew from the partnership as the
general partner and assigned 1% of 7% interest to the new general partner, CHA
Properties Inc. ("CHA"). WFA retained its remaining 6% interest which was
converted to a limited partnership interest but is not considered an investor
limited partner. Profits, losses and distributions of the partnership are
allocated 1% to the general partner, 6% to WFA and 93% to the investor limited
partners.
 
  Basis of Presentation
 
     The Partnership prepares its financial statements on the accrual basis of
accounting.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. The Partnership depreciates
the property on the straight-line method over their estimated useful lives for
financial statement purposes. For income tax purposes, accelerated methods and
lives are used.
 
  Deferred Costs
 
     Deferred costs are capitalized and amortized on the straight-line method
over the term of the related agreements as discussed in note B.
 
  Income Taxes
 
     No provision has been made for federal, state or local income taxes in the
financial statements of the Partnership. The Partners are required to report on
their individual income tax returns their allocable share of income, gains,
losses, deductions and credits of the Partnership. The Partnership files its own
tax return on the accrual basis.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the Partnership and
tenants of the property are operating leases.

  Cash Equivalents
 
     For the purpose of the statement of cash flows, the partnership considers
all highly liquid investments to be cash equivalents. The carrying amount in
1996 of $3,873,025 and in 1995 of $431,651 approximates fair value because of
the short maturity of this instrument.
 
     The following is a summary of deferred costs at December 31, 1996 and 1995:

NOTE I -- COMMITMENTS
 
  Lead Based Paint Agreement
 
     In connection with the refinancing of the mortgage note, the Partnership
was required to perform an environmental assessment of the Property. It was
determined through sampling and analysis that part of the Property may contain
"Lead Based Paint". As a condition to the making of the mortgage note, the
Partnership is required to develop, implement and carry out an operations and
maintenance plan for "Lead Based Paint" on the Property ("O & M Plan"). The "O &
M Plan" requires that in event the Partnership desires to make renovations to or
demolish the Property or any portion, thereof, the Partnership is required to
have all painted surfaces (including all underlying paint layers) at the
Property that are being renovated or demolished tested for the presence of Lead
Based Paint by a qualified environmental consultant. If such tests indicate the
presence of Lead Based Paint at the Property, the Partnership is required at
their expense, to remove all Lead Based Paint in accordance with all applicable
local, state and federal laws.
 
  Asbestos Operations and Maintenance Agreement
 
     As a condition of making the loan, the Partnership has agreed to develop an
operations and maintenance program for the Property with respect to the presence
of asbestos (the "O & M Program"). The Operations and Maintenance Program has
been established to minimize potential exposures to asbestos fibers from
asbestos containing material ("ACM") present in the property. The program has
been designed to reduce the possibility of disturbing ACM during maintenance,

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   1369
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1370
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.

     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1376
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     -  Immediate liquidity. If you tender your units for cash, you will receive
        $     per unit. However, tendering your units for cash may cause you to
        recognize taxable gain for Federal income tax purposes.
 
     -  Ease of tax reporting. After this year, you will not receive a Schedule
        K-1 tax form containing tax information used for preparing your Federal
        income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $1,113.75 per unit for the six
     months ended June 30, 1998 (equivalent to $2,227.50 on an annual basis). We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if 50% or more of the
     total interests in your partnership are transferred within a 12-month
     period. If we acquire a significant percentage of the interest in your
     partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership. In addition, there is a sale or exchange of 50% or more of the
     total interest in capital and profits of your partnership within any
     12-month period, including sales or exchanges resulting from the offer,
     your partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your
 
                                       S-4
<PAGE>   1378
 
     partnership using the direct capitalization method. This method involves
     applying a capitalization rate to your partnership's annual net operating
     income. We determined an appropriate capitalization rate using our best
     judgment, but our valuation is just an estimate. Although the direct
     capitalization method is a widely-accepted way of valuing real estate,
     there are a number of other methods available to value real estate, each of
     which may result in different valuations of the property. The proceeds that
     you would receive if you sold your units to someone else or if your
     partnership were actually liquidated might be higher or lower than our
     offer consideration. An actual liquidation may also result in your paying
     taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.

Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.

     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being

RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1381
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code.
 
     The particular tax consequences to you of the exchange will depend upon a
number of factors related to your individual tax situation, including your tax
basis in your units, whether you dispose of all of your units in your
partnership, and whether the "passive loss" rules apply to your investments.
Because the income tax consequences of an exchange of units will not be the same
for everyone, you should consult your tax advisor before determining whether to
tender your units pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   1382
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   1383
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   1384
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   1385
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the
 
                                      S-12
<PAGE>   1386
 
     continued operation of your partnership. Given improving rental market
     conditions, the level of distributions might increase over time. We believe
     it is possible that the private resale market for apartment and retail
     properties could improve over time, making a sale of your partnership's
     property in a private transaction at some point in the future a more viable
     option than it is currently. However, there are several risks and
     disadvantages that result from continuing the operations of your
     partnership without the offer. Your partnership faces maturity or balloon
     payment dates on its mortgage loans and must either obtain refinancing or
     sell its property. If your partnership were to continue operating as
     presently structured, it could be forced to borrow on terms that could
     result in net losses from operations. In addition, continuation of your
     partnership without the offer would deny you and your partners the benefits
     that your general partner expects to result from the offer. For example, a
     partner of your partnership would have no opportunity for liquidity unless
     he were to sell his units in a private transaction. Any such sale would
     likely be at a very substantial discount from the partner's pro rata share
     of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future
                                      S-13
<PAGE>   1387
 
      increase in the AIMCO stock price and from any future increase in
      distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."
 
TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %
Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any combination
of such forms of consideration for your units. The offer is made upon the terms
and subject to the conditions set forth in this Prospectus Supplement, the
accompanying Prospectus and the accompanying Letter of Transmittal, including
the instructions thereto, as the same may be supplemented or amended from time
to time (the "Letter of Transmittal"). To be eligible to receive Tax-Deferral
     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an
opportunity to increase our investment in apartment properties, and provide you

       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making

jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
 
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions, liquidity and
transfer and redemption rights. See "Comparison of Preferred OP Units and Class
I Preferred Stock" for a chart highlighting such differences.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents 100% of the closing price of
AIMCO's Class A Common Stock on the NYSE on a recent date before we commenced
this offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 1/4 of
1% of gross operating revenues of your partnership's property, payable monthly,
and may receive reimbursement for expenses generated in its capacity as general
partner of your partnership. The property manager received management fees of
$82,000 in 1996, $87,000 in 1997 and $44,102 for the first six months of 1998.
We have no current intention of changing the fee structure for your property
manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine
 
                                      S-18
<PAGE>   1392
 
precisely the confines of the market area for particular properties and some
competition may exist. Furthermore, you should bear in mind that we anticipate
acquiring properties in general market areas where your partnership's property
is located. It is believed that this concentration of properties in a general
market area will facilitate overall operations through collective advertising
efforts, staffing and other operational efficiencies. In managing our
properties, we will attempt to reduce such conflicts between competing
properties by referring prospective tenants to the property considered to be
most conveniently located for the tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Coastal Commons Limited Partnership is a
South Carolina limited partnership which was formed on June 29, 1984 for the
purpose of owning and operating a single apartment property located in Mt.
Pleasant, South Carolina, known as "Hibben Ferry Apartments". In 1984, it
completed a private placement of units that raised net proceeds of approximately
$15,300,000. Hibben Court Apartments consists of 240 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2014, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $6,209,522, payable to First Union
National Bank, which bears interest at a rate of 8.08%. The mortgage debt is due
in July, 2002. Your partnership's agreement of limited partnership also allows
your general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1400
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units solely for
purchase. Accordingly, following the purchase of your units, we would be
entitled to receive any future distributions from the operations of your
partnership to the extent of the units we acquire. Similarly, if you tender your
units for OP Units, you will be entitled to future distributions from the
operations of the AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single
 
                                      S-27
<PAGE>   1401
 
apartment property. In contrast, the AIMCO Operating Partnership is in the
business of acquiring, marketing, managing and operating a large portfolio of
apartment properties. While diversification of assets may reduce certain risks
of investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 1998 were $1,113.75 per unit (equivalent to
$2,227.50 on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations
 
                                      S-28
<PAGE>   1402
 
may cause your general partner to reduce the liabilities of your partnership. If
the liabilities of your partnership were to be reduced, and you do not tender
all of your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     Your partnership's agreement of limited partnership prohibits any transfer
of units without the consent of the general partner. Such consent may be
withheld by the general partner in its sole discretion. The general partner may
withhold its consent if such transfer would result in the termination of your
partnership for tax purposes which will occur if more than 50% or more of the
total interests in your partnership are transferred within a 12-month period. If
we acquire a significant percentage of the interest in your partnership, the
general partner may not consent to a transfer for a 12-month period following
the offer.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO to
negative from stable to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same, Moody's confirmed its
existing rating on AIMCO's existing preferred stock and senior debt.

                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction.
 
                                      S-30
<PAGE>   1404
 
Any such sale likely would be at a very substantial discount from your pro rata
share of the fair market value of your partnership's property and might involve
significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral      % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
                                      S-31
<PAGE>   1405
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   1407
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   1408
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-35
<PAGE>   1409
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-36
<PAGE>   1410
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
                                      S-37
<PAGE>   1411
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.

     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     or other lending institutions, or (viii) in the case of any of the

<PAGE>   1414
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced
     or publicly proposed to be made by another person or "group" (as defined in
     Section 13(d)(3) of the Securities Exchange Act of 1934), or it shall have

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-41
<PAGE>   1415
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-43
<PAGE>   1417
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-44
<PAGE>   1418
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   1425
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   1426
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including

     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-56
<PAGE>   1430
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 1998 were 1,113.75 (equivalent to 2,227.50 on an
     annualized basis. This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units, that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-57
<PAGE>   1431
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-58

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Price............................................    $

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
                                      S-59
<PAGE>   1433
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

<PAGE>   1434
 
     performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-61

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 1/4 of
1% of gross operating revenues of your partnership's property, payable monthly,
and may receive reimbursement for expenses generated in its capacity as general
partner from your partnership. The property manager received management fees of
$82,000 in 1996, $87,000 in 1997 and $44,102 for the first six months of 1998.
The AIMCO Operating Partnership has no current intention of changing the fee
structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Coastal Commons Limited Partnership is a South Carolina limited partnership
which raised net proceeds of approximately $15,300,000 in 1984 through a private
offering. The promoter for the private offering of your partnership was US
Shelter Corporation. Insignia acquired your partnership in December 1990. AIMCO
acquired Insignia in October, 1998. There are currently a total of 229 limited
partners of your partnership and a total of 200 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on June 29, 1984 for the purpose of owning and
operating a single apartment property located in Mt. Pleasant, South Carolina,
known as "Hibben Ferry Apartments." Your partnership's property consists of 240
apartment units. There are 48 one-bedroom apartments and 192 two-bedroom
apartments. The total rentable square footage of your partnership's property is
234,480 square feet. Your partnership's property had an average occupancy rate
of approximately 92.92% in 1996 and 92.92% in 1997. The average annual rent per
apartment unit is approximately $6,844.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $82,000, $87,000 and $44,102, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2014
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $6,209,522, payable to First Union National Bank, which bears
interest at a rate of 8.08%. The mortgage debt is due in July, 2002. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

costs, totaled $265,126 for the six months ended June 30, 1998, compared to

$1,668,000 for the year ended December 31, 1996, compared to $1,539,954 for the
year ended December 31, 1995, an increase of $128,046, or 8.31%. This increase
was primarily a result of an increase in demand for corporate units from the
Coast Guard and a steel company.

     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $853,000 for the
year ended December 31, 1996, compared to $656,850 for the year ended December

compared to $77,155 for the year ended December 31, 1995, an increase of $4,845,

December 31, 1996 compared to $74,334 for the year ended December 31, 1995, a
decrease of $46,334 or 62.33%. The decrease is primarily due to a decrease in
legal and professional expenses as well as reclassing various general and
administrative expenses for 1995 to operating expenses for 1996.
 
                                      S-78
<PAGE>   1452
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $539,000 for the year ended December 31, 1996, compared to
$577,734 for the year ended December 31, 1995, a decrease of $38,734, or 6.70%.
The decrease is due primarily to refinancing mortgage note payable which was due
April 1995.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $404,974 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable to your partnership or any limited partner for any
acts performed or any failure to act by any of them performed or omitted in good
faith, provided that such course of conduct did not constitute fraud, gross
negligence or willful misconduct. As a result, unitholders might have a more
limited right of action in certain circumstances than they would have in the
absence of such a provision in your partnership's agreement of limited
partnership. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest".
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss or damage resulting from any act or omission
performed or omitted in good faith, which does not constitute fraud, gross
negligence or willful misconduct. Moreover, the general partner is not liable to
your partnership or the limited partners because any taxing authorities
disallowed or adjusted any deductions or credits in your partnership income tax
returns. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because

admission of the transferee as a substitute limited partner in your partnership
require the consent of the general partner of your partnership under your
partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner) was as follows:

                                  (UNAUDITED)
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Coastal Commons Limited
Partnership as of June 30, 1998 and for the six months ended June 30, 1998 and
1997 have been prepared in accordance with the accounting basis for federal
income tax reporting. Accordingly, they do not include all the information and
footnotes required by the accounting basis for federal income tax reporting for
complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

The Partners
Coastal Commons Limited Partnership
 
     We have audited the accompanying consolidated balance sheet of Coastal
Commons Limited Partnership as of December 31, 1997 and the related consolidated
statements of operations, changes in partners' deficit and cash flows for the
year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Coastal Commons
Limited Partnership at December 31, 1997 and the consolidated results of its
operations and cash flows for the year then ended in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Coastal Commons Limited Partnership (the "Partnership") was organized as a
limited partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated June 29, 1984 and
extending to December 31, 2014, unless terminated sooner. Two hundred units of
limited partnership interests, an individual general partner interest and two
corporate general partner interests were issued. The Partnership owns and
operates a 240-unit apartment complex, Hibben Ferry Apartments, in Mt. Pleasant,
South Carolina.
 
  Principles of Consolidation
 
     The consolidated financial statements include all of the accounts of the
Partnership's 79%-owned subsidiary Hibben Ferry Recreation Center, which owns
recreational property used jointly by Hibben Ferry Apartments and a condominium
complex owned and operated by an unaffiliated party. All significant
intercompany accounts have been eliminated in consolidation. Minority interest
represents the 21% non-affiliated ownership interest in Hibben Ferry Recreation
Center.
 
  Investment Property
 
     Investment property is stated at cost. Acquisition fees are capitalized as
a cost of real estate. The Partnership records impairment losses on long-lived
assets used in operations when events and circumstances indicated that the
assets might be impaired and the undiscounted cash flows estimated to be
generated by those assets are less than the carrying amounts of those assets. No
adjustments for impairment of value were necessary for the year ended December
31, 1997.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Risks and Uncertainties
 
     The real estate business is highly competitive. The Partnership's real
property investments are subject to competition from similar types of properties
in the vicinities in which they are located and the Partnership is not a
significant factor in its industry. In addition, various limited partnerships
have been formed by related parties to engage in business which may be
competitive with the Partnership.
 
  Cash and Cash Equivalents
 
     Cash on hand and in banks, and money market funds and certificates of
deposit with original maturities of three months or less are considered to be
unrestricted cash. At certain times, the amount of cash deposited at a bank may
exceed the limit on insured deposits.
 
  Fair Value of Financial Instruments
 
     The Partnership believes that the carrying amount of its financial
instruments (except for long term debt) approximates their fair value due to the
short term maturity of these instruments. The fair value of the Partnership's
long-term debt, after discounting the scheduled loan payments at an estimated
borrowing rate currently available to the Partnership, approximates its carrying
value.

                      COASTAL COMMONS LIMITED PARTNERSHIP
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the loan.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits." Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit and the tenant is current on its rental payments.
 
  Restricted Escrows
 
     A Replacement Reserve was established at the time of the refinancing of the
mortgage note payable encumbering the apartment property to cover necessary
costs and expenses incurred for capital improvements. The Partnership is
required to make a monthly deposit of $4,000 to the reserve. At December 31,
1997, the account balance was approximately $125,000. There is also
approximately $35,000 in replacement reserves for the Hibben Ferry Recreation
Center.
 
  Partnership Allocations
 
     Net earnings or loss, distributions to partners, and taxable income or loss
are allocated to the partners in accordance with the partnership agreement.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less. Rental revenue is recognized as earned.
 
  Advertising Costs
 
     The Partnership expenses the costs of advertising as incurred.
 
  Depreciation
 
     Building and improvements are depreciated using the straight-line method
over the estimated useful lives of the assets, ranging from 5 to 30 years.
 
NOTE B -- MORTGAGE NOTE PAYABLE
 
     The mortgage note of approximately $6,240,000 bears interest at 8.08% and
is payable in monthly principal and interest installments of approximately
$47,000 with a balloon payment of approximately $5,909,000 at maturity on July
1, 2002.
 
     The mortgage note payable is non-recourse and requires prepayment penalties
if repaid prior to maturity and prohibits resale of the property subject to the
existing indebtedness. The mortgage note payable is secured by pledge of the
apartment property and by pledge of revenues from the apartment property.

NOTE C -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     Affiliates of Insignia Financial Group, Inc. ("Insignia") own the
controlling ownership interest in the Partnership's Managing General Partner,
with certain affiliates of Insignia providing property management and asset
management services to the Partnership.
 
     The following payments were made to Insignia and its affiliates in 1997 (in
thousands):

Property management fees....................................   $87
General partner expenses....................................    12
Asset management fees.......................................     4
</TABLE>
 
     Insignia entered into an Agreement and Plan of Merger, dated as of May 26,
1998, (as subsequently amended and restated, the "Merger Agreement") with
Apartment Investment and Management Company ("AIMCO"), pursuant to which
Insignia will merge its national residential property management operations and
its controlling interest in Insignia Properties Trust with and into AIMCO, with
AIMCO as the survivor. Consummation of the Merger, which is anticipated to occur
in the third quarter of 1998, is subject to certain conditions, including the
approval of the stockholders of Insignia (but not the approval of the
stockholders of AIMCO). If the closing occurs, AIMCO will then control the
General Partner of the Partnership.
 
     For the period of January 1, 1997, to August 31, 1997, the Partnership
insured its property under a master policy through an agency and insurer
unaffiliated with the Managing General Partner. An affiliate of the Managing
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the master policy. The agent assumed the financial obligations to the
affiliate of the Managing General Partner who received payments on these
obligations from the agent. The amount of the Partnership's insurance premiums
that accrued to the benefit of the affiliate of the Managing General Partner by
virtue of the agent's obligations was not significant.

NOTE F -- YEAR 2000 (UNAUDITED)
 
     The Partnership is dependent upon the General Partner and Insignia for
management and administrative services. Insignia has completed an assessment and
will have to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter (the "Year 2000 Issue"). The project is estimated to be completed not
later than December 31, 1998, which is prior to any anticipated impact on its
operating systems. The General partner believes that with modifications to
existing software and conversions to new software, the Year 2000 Issue will not
pose significant operational problems for its computer systems. However, if such
modifications and conversions are not made, or are not completed timely, the
Year 2000 Issue could have a material impact on the operations of the
Partnership.
 
NOTE G -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Coastal Commons Limited Partnership
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Coastal Commons Limited
Partnership (the "Partnership") as of December 31, 1997, and the related
statement of revenues, expenses and changes in partners' deficit -- Federal
income tax basis for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note A, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Coastal Commons Limited Partnership at December 31, 1997, and its revenues,
expenses and changes in partners' deficit for the year then ended, on the basis
of accounting described in Note A.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Coastal Commons Limited Partnership (the "Partnership") was organized as a
limited partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated June 29, 1984 and
extending to December 31, 2014, unless terminated sooner. The Partnership owns
and operates a 240-unit apartment complex, Hibben Ferry Apartments, in Mt.
Pleasant, South Carolina.
 
     In addition, the Partnership owns 240 of the 304 outstanding shares of
Hibben Ferry Recreation, Inc., a non-profit corporation which owns recreational
property used jointly by Hibben Ferry Apartments and a condominium complex owned
and operated by an unaffiliated party.
 
  Basis of Accounting
 
     The financial statements are prepared on the accrual basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The tax basis used differs
from GAAP primarily because on the tax basis (1) certain rental income received
in advance is recorded as income in the year received rather than in the year
earned, (2) buildings and related personal property are depreciated using the
lives specified under the accelerated cost recovery system ("ACRS") or the
modified accelerated cost recovery system ("MACRS") instead of over the
estimated lives of the assets, and (3) the investment in Hibben Ferry
Recreation, Inc. is carried on the cost method instead of consolidating the
accounts of this majority-owned subsidiary, and (4) recognition and amortization
of syndication costs.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Under ACRS, depreciation is based on accelerated methods (1) for real
property over 18 years for additions before May 9, 1985 and 19 years for
additions after May 8, 1985 and before January 1, 1987 and (2) for personal
property over 5 years for additions prior to January 1, 1987. As a result of the
Tax Reform Act of 1986, MACRS is used (1) for real property over 27 1/2 years
for additions after December 31, 1986 and (2) for personal property over 7 years
for additions after December 31, 1986.
 
  Restricted Escrows
 
     Replacement Reserve -- At the time of the refinancing of Hibben Ferry
Apartments in 1995, a replacement reserve was established to cover necessary
costs and expenses incurred for capital improvements. The Partnership is
required to make a monthly deposit of $4,000 to the reserve. At December 31,
1997, the account balance was approximately $125,000.
 
  Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital of
approximately $1,605,000 have been capitalized and represent a deferred charge
deductible upon termination of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.

investments with a maturity of three months or less as cash equivalents. At
certain times, the amount of cash deposited at a bank may exceed the limit on
insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and includes the deposits in "Receivables and deposits".
Deposits are refunded when the tenant vacates the apartment if there has been no
damage to the unit.
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the loan.
 
  Income Taxes
 
     No provision has been made for income taxes in the accompanying financial
statements since such taxes, if any, are the liability of the individual
partners.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
NOTE B -- MORTGAGE NOTE PAYABLE
 
     The mortgage note of approximately $6,240,000 bears interest at 8.08% and
is payable in monthly principal and interest installments of approximately
$47,000 with a balloon payment of approximately $5,909,000 at maturity on July
1, 2002.
 
     The mortgage note payable is non-recourse and requires prepayment penalties
if repaid prior to maturity and prohibits resale of the property subject to the
existing indebtedness. The mortgage note payable is secured by pledge of the
apartment property and by pledge of revenues from the apartment property.
 
     Scheduled principal payments of the mortgage note payable subsequent to
December 31, are as follows (in thousands):

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Coastal Commons Limited Partnership
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Coastal Commons Limited
Partnership (the "Partnership") as of December 31, 1996, and the related
statement of revenues, expenses and changes in partners' deficit -- Federal
income tax basis for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note A, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Coastal Commons Limited Partnership as of December 31, 1996, and its revenues,
expenses and changes in partners' deficit for the year then ended, on the basis
of accounting described in Note A.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Coastal Commons Limited Partnership (the "Partnership") was organized as a
limited partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated June 29, 1984 and
extending to December 31, 2014, unless terminated sooner. The Partnership owns
and operates a 240-unit apartment complex, Hibben Ferry Apartments, in Mt.
Pleasant, South Carolina.
 
     In addition, the Partnership owns 240 of the 304 outstanding shares of
Hibben Ferry Recreation, Inc., a non-profit corporation which owns recreational
property used jointly by Hibben Ferry Apartments and a condominium complex owned
and operated by an unaffiliated party.
 
  Basis of Accounting
 
     The financial statements are prepared on the accrual basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The tax basis used differs
from GAAP primarily because on the tax basis (1) certain rental income received
in advance is recorded as income in the year received rather than in the year
earned, (2) buildings and related personal property are depreciated using the
lives specified under the accelerated cost recovery system ("ACRS") or the
modified accelerated cost recovery system ("MACRS") instead of over the
estimated lives of the assets, and (3) the investment in Hibben Ferry
Recreation, Inc. is carried on the cost method instead of consolidating the
accounts of this majority-owned subsidiary, and (4) recognition and amortization
of syndication costs.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Under ACRS, depreciation is based on accelerated methods (1) for real
property over 18 years for additions before May 9, 1985 and 19 years for
additions after May 8, 1985 and before January 1, 1987 and (2) for personal
property over 5 years for additions prior to January 1, 1987. As a result of the
Tax Reform Act of 1986, MACRS is used (1) for real property over 27 1/2 years
for additions after December 31, 1986 and (2) for personal property over 7 years
for additions after December 31, 1986.
 
  Restricted Escrows
 
     Replacement Reserve -- At the time of the refinancing of Hibben Ferry
Apartments in 1995, a replacement reserve was established to cover necessary
costs and expenses incurred for capital improvements. The Partnership is
required to make a monthly deposit of $4,000 to the reserve. At December 31,
1996, the account balance was approximately $71,000.
 
  Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital of
approximately $1,605,000 have been capitalized and represent a deferred charge
deductible upon termination of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.

    NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS -- (CONTINUED)
 
  Cash and Cash Equivalents -- Unrestricted Cash
 
     It is the Partnership's policy to classify all liquid short-term
investments with a maturity of three months or less as cash equivalents. At
certain times, the amount of cash deposited at a bank may exceed the limit on
insured deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and considers the deposits to be restricted cash. Deposits
are refunded when the tenant vacates the apartment if there has been no damage
to the unit.
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the loan.
 
  Income Taxes
 
     No provision has been made for income taxes in the accompanying financial
statements since such taxes, if any, are the liability of the individual
partners.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
NOTE B -- MORTGAGE NOTE PAYABLE
 
     The mortgage note of approximately $6,299,000 bears interest at 8.08% and
is payable in monthly principal and interest installments of approximately
$47,000 with a balloon payment of approximately $5,909,000 at maturity on July
1, 2002.
 
     The mortgage note payable is non-recourse and requires prepayment penalties
if repaid prior to maturity and prohibits resale of the property subject to the
existing indebtedness. The mortgage note payable is secured by pledge of the
apartment property and by pledge of revenues from the apartment property.

December 31, are as follows (in thousands):

The Partners
Coastal Commons Limited Partnership
 
     We have audited the accompanying statement of assets, liabilities and

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1995
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Coastal Commons Limited Partnership (the "Partnership") was organized as a
limited partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated June 29, 1984 and
extending to December 31, 2014, unless terminated sooner. The Partnership owns
and operates a 240-unit apartment complex, Hibben Ferry Apartments, in Mt.
Pleasant, South Carolina.
 
     In addition, the Partnership owns 240 of the 304 outstanding shares of
Hibben Ferry Recreation, Inc., a non-profit corporation which owns recreational
property used jointly by Hibben Ferry Apartments and a condominium complex owned
and operated by an unaffiliated party.
 
  Basis of Accounting
 
     The financial statements are prepared on the accrual basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The tax basis used differs
from GAAP primarily because on the tax basis (1) certain rental income received
in advance is recorded as income in the year received rather than in the year
earned, (2) buildings and related personal property are depreciated using the
lives specified under the accelerated cost recovery system ("ACRS") or the
modified accelerated cost recovery system ("MACRS") instead of over the
estimated lives of the assets, and (3) the investment in Hibben Ferry
Recreation, Inc. is carried on the cost method instead of consolidating the
accounts of this majority-owned subsidiary, and (4) recognition and amortization
of syndication costs.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Under ACRS, depreciation is based on accelerated methods (1) for real
property over 18 years for additions before May 9, 1985 and 19 years for
additions after May 8, 1985 and before January 1, 1987 and (2) for personal
property over 5 years for additions prior to January 1, 1987. As a result of the
Tax Reform Act of 1986, MACRS is used (1) for real property over 27 1/2 years
for additions after December 31, 1986 and (2) for personal property over 7 years
for additions after December 31, 1986.
 
  Restricted Escrows
 
     Repair and Remediation Reserve -- At the time of the refinancing of Hibben
Ferry Apartments in 1995, $104,875 was designated for a repair and remediation
reserve for general maintenance, repairs, or corrective work at the property to
be completed in 1995. At December 31, 1995, the entire balance remained in the
escrow. All work has been completed and the funds will be released upon
inspection of the work by the Mortgagee in 1996.
 
     Replacement Reserve -- In addition to the Repair and Remediation Reserve
established in 1995, a replacement reserve was established to cover necessary
costs and expenses incurred for capital improvements. The Partnership is
required to make a monthly deposit of $4,140 to the reserve. At December 31,
1995, the account balance was $20,700.

                      COASTAL COMMONS LIMITED PARTNERSHIP
 
    NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS -- (CONTINUED)
 
  Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital of
$1,605,036 have been capitalized and represent a deferred charge deductible upon
termination of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage to the unit.
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the loan.
 
  Income Taxes
 
     No provision has been made for income taxes in the accompanying financial
statements since such taxes, if any, are the liability of the individual
partners.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
2. MORTGAGE NOTE PAYABLE
 
     The mortgage note of $6,353,672 bears interest at 8.08% and is payable in
monthly principal and interest installments of $47,134 with a balloon payment of
$5,901,749 at maturity on July 1, 2002.
 
     The mortgage note payable is non-recourse and requires prepayment penalties
if repaid prior to maturity and prohibits resale of the property subject to the
existing indebtedness. The mortgage note payable is secured by pledge of the
apartment property and by pledge of revenues from the apartment property.

NOTE 4 -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   1489
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the Partnership's present capitalization or distribution policy; or
any other material changes in the Partnership's structure or business.

<PAGE>   1490
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     DFW Apartment Investors Limited Partnership. For each unit that you tender,
     you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,394 million and stockholders' equity of $1,314 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972, total debt of $1,626 and stockholders' equity
     of $1,844.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner (the "general partner") of
     your partnership and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1495
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1496
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $2,600 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $     per year on the number of Tax-Deferral
       % Preferred OP Units, or distributions of $     year on the number of
     Tax-Deferral Common OP Units, that you would receive in an exchange for
     each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income
 
                                       S-3
<PAGE>   1497
 
     tax purposes, as a partial sale of such units for cash, and as a partial
     tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   1498
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1501
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   1502
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   1503
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   1504
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   1505
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 13.35% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   1506
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore

<PAGE>   1508
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by

Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a
 
                                      S-16
<PAGE>   1510
 
     number of factors, including your financial needs, other financial
opportunities available to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, the general partner of your partnership is entitled to fees for
its services as general partner while the general partner of the AIMCO Operating
Partnership is not entitled to such fees.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment,
 
                                      S-17
<PAGE>   1511
 
voting rights, distributions and liquidity and transferability/redemption. For
example, unlike the AIMCO OP Units, you have no redemption rights with respect
to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of $40,000 beginning in 1990 and increasing annually at a rate of 5%
beginning in 1991 and may receive reimbursement for expenses generated in its
capacity as general partner from your partnership. The property manager received
management fees of $195,660 in 1996, $209,666 in 1997 and $107,798 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager. The general partner of your partnership receives an
annual fee of $40,000 beginning in 1990 and increasing annually at a rate of 5%
beginning in 1991 from your partnership.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. DFW Apartment Investors Limited
Partnership is a Delaware limited partnership which was formed on May 2, 1990
for the purpose of owning and operating a small number of apartment properties
located in Irving, Texas, Arlington, Texas and Euless, Texas, known as "Heather

respectively. In 1990, it completed a private placement of units that raised net
proceeds of approximately $20,600,000. Heather Ridge Apartments and Oak Forest
Apartments each consists of 204 apartment units and Hillcrest Apartments
consists of 298 apartment units. Your partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and

suppliers and independent contractors. The property manager is affiliated with
us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2040, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
current mortgage notes outstanding on "Heather Ridge Apartments" of $3,744,013,
on "Hillcrest Apartments" of $3,775,476 and on "Oak Forest Apartments" of
$2,898,497. All three mortgage notes are payable to AMI Capital, bear interest
at a rate of 7.53% and are due May 2003. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has a loan outstanding to
your partnership of $     , bearing interest at a rate of      %, due      .
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1520
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1521
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and the distributions with respect to
your units for the year ended December 31, 1997 were $2,600 per unit. This is
equivalent to distributions of $     per year on the number of Tax-Deferral   %
Preferred OP Units, or distributions of $     year on the number of Tax-Deferral
Common OP Units, that you would receive in an exchange for each of your
partnership's units. Therefore, distributions with respect to the Preferred OP
Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 13.35% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   1523
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   1524
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Preferred Quarterly Distributions. We pay quarterly distributions on the
       Common OP Units. For the quarter ended June 30, 1998, we paid
       distributions of Common OP Units. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1526
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1527
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

 Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation
 to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   1529
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought. Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   1531
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

        (f) a tender or exchange offer for any units shall have been commenced

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   1534
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42

     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   1537
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   1539
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   1544
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   1545
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   1547
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   1548
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and the distributions with respect to your
     units for the year ended December 31, 1997 were $2,600. This is equivalent
     to distributions of $          per year on the number of Tax-Deferral
          % Preferred OP Units, or distributions of $          per year on the
     number of Tax-Deferral Common OP Units, that you would receive in exchange
     for each of your partnership's units. Therefore, distributions with respect
     to the Preferred OP Units and Common OP Units that we are offering are
     expected to be        , immediately following our offer, than the
     distributions with respect to your units. See "Comparison of Ownership of
     Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   1549
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and
through June 30, 1998; (v) reviewed operating budgets for your partnership's

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,

     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with
respect to your partnership. In addition, Stanger is entitled to reimbursement
for reasonable legal, travel and out-of-pocket expenses incurred in making the
site visits and preparing the Fairness Opinion, and is entitled to
indemnification against certain liabilities, including certain liabilities under
Federal securities laws. No portion of Stanger's fee is contingent upon
consummation of the offer or the content of Stanger's opinion. Stanger has
performed other services for AIMCO in the past, including: general financial
advisory services relating to a potential acquisition by AIMCO. However, such
acquisition was never completed and no fee was paid to Stanger.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of $40,000 beginning in 1990 and increasing annually at a rate of 5%
beginning in 1991 and you may receive reimbursement for expenses generated in
that capacity from your partnership. The property manager received management
fees of $195,660 in 1996, $209,666 in 1997 and $107,798 for the first six months
of 1998. The AIMCO Operating Partnership has no current intention of changing
the fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     La Colina Partners, Ltd. is a Delaware limited partnership which raised net
proceeds of approximately $20,600,000 in 1990 through a private offering. The

PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $195,660, $209,666 and $107,798, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2040
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.

     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES

also allows the general partner of your partnership to lend funds to your
partnership. Currently, the general partner of your partnership has a loan
outstanding to your partnership of $       , bearing interest at a rate of   %,
due                .
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not

increased expenses over increased revenues. These factors are discussed in more
detail in the following paragraphs.

for the year ended December 31, 1997, compared to $195,660 for the year ended

     outstanding debt, capital improvements, and distributions paid to limited
partners. Your partnership has adequate sources of cash to finance its
operations, both on a short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable for damages or
otherwise to your partnership or any limited partner for any acts performed or
any failure to act by any of them if they determined, in good faith, that such
acts or failure to act was in the best interests of your partnership, and such
course of conduct did not constitute negligence or misconduct on the part of
such party. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss, damage, liability, cost or expense sustained
by it or them in connection with your partnership, provided that such loss,
damage, liability, cost or expense was not the result of negligence or
misconduct by such party. However, neither the general partner nor any affiliate
will be indemnified for any loss, damage or cost resulting from the violation of
any Federal or state securities laws in connection with the sale of units and
will be liable for such violations unless (i) there has been a successful
adjudication on the merits of each count involving the securities law
violations, (ii) such claims have been dismissed with prejudice on the merits by
a court of competent jurisdiction or (iii) or court of competent jurisdiction
approves a settlement of such claims. In such claim for indemnification for
Federal or state securities law violation, the party seeking indemnification
must place before the court the position of the SEC and any other applicable
regulatory agency with respect of the issue of indemnification for securities
law violations. Any such indemnity provided shall be paid, from and only to the
extent of, partnership assets. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     No partnership funds will be used to purchase any insurance that insures
any party against any liability for which indemnification is not available
pursuant to your partnership's agreement of limited partnership.

     The following table sets forth the distributions paid per unit in the

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in
 
                                      S-76
<PAGE>   1570
 
     order to track compliance with safe harbor provisions to avoid treatment as
a "publicly traded partnership" for tax purposes. However, the general partner
of your partnership does not monitor or regularly receive or maintain
information regarding the prices at which secondary sale transactions in the
units have been effectuated. The general partner of your partnership estimates,
based solely on the transfer records of your partnership (or your partnership's
transfer agent), that there have been no units transferred in sale transactions
(excluding transactions believed to be between related parties, family members
or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     AIMCO currently owns a 13.35% limited partnership interest in your
partnership. Except as described above, Neither AIMCO, nor, to the best of its
knowledge, any of its affiliates, (i) beneficially own or have a right to
acquire any units, (ii) have effected any transaction in the units, or (iii)
have any contract, arrangement, understanding or relationship with any other
person with respect to any securities of your partnership, including, but not
limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of DFW Apartment Investors
Limited Partnership as of June 30, 1998 and for the six months then ended have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
DFW Apartment Investors Limited Partnership
 
     We have audited the accompanying balance sheets of DFW Apartment Investors
Limited Partnership as of December 31, 1997, and 1996, and the related
statements of income, partners' capital and cash flows for the years then ended.
These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on the financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of DFW Apartment Investors
Limited Partnership as of December 31, 1997, and 1996, and the results of its
operations, changes in partners' capital and cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     DFW Apartment Investors Limited Partnership (the "Partnership") was formed
April 25, 1990 under the laws of the State of Delaware for the purposes of
acquiring, renovating, operating and otherwise dealing with certain residential
apartments located in the Dallas/Fort Worth, Texas metropolitan area. The
Partnership will terminate on December 31, 2040, or earlier upon the occurrence
of certain events specified in the Partnership Agreement.
 
     The general partner of the Partnership is Winthrop Financial Associates, a
Maryland Limited Partnership ("WFA"). WFC Realty Co., Inc., a Massachusetts
Corporation ("WFC Realty"), a wholly-owned subsidiary of WFA, was the initial
limited partner of the Partnership and withdrew as limited partner upon the
first admission of investors. The Partnership sold 206 limited partnership units
at $100,000 per unit.
 
     In accordance with the Partnership Agreement, losses and cash flow shall be
allocated 99% to investor limited partners and 1% to WFA; income shall be
allocated to the partners in proportion to the cash available for distribution
distributable to the partners. If there is no such cash available for
distribution, income will be allocated 95% to limited partners and 5% to WFA.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with generally accepted accounting principles.
 
  Rental Property
 
     Rental property is carried at cost. Depreciation is provided for in amounts
sufficient to relate the cost of depreciable assets to operations over their
estimated service lives by use of the straight-line method for financial
reporting purposes. For income tax purposes, accelerated lives and methods are
used.
 
  Deferred Costs
 
     Deferred costs are amortized using the straight-line method over the term
of the related agreement.
 
  Income Taxes
 
     No provision will be made for federal, state or local income taxes in the
financial statements of the Partnership. Partners will be required to report on
their tax returns their allocable shares of income, gains, losses, deductions
and credits of the Partnership.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the Partnership and
tenants of the Properties are operating leases.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the Partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents.
 
NOTE B -- ACQUISITION OF THE PROPERTIES
 
     The Partnership acquired three separate residential apartment complexes
(the "Properties") in 1990 for an aggregate purchase price of $14,013,732. The
purchase represents an aggregate of 707 market-rate rental apartments in the
Dallas, Texas area.
 
     On June 8, 1990, the Partnership acquired Heather Ridge Apartments for
$5,104,350. On August 16, 1990 and September 19, 1990, the Partnership acquired
Oak Forest Apartments and Summit on Post Oak Apartments for $4,409,382 and
$4,500,000, respectively. The purchases were financed by a loan from Citibank,
N.A. and an advance from WFA.
 
NOTE C -- MORTGAGES PAYABLE
 
     On April 15, 1996, the Partnership obtained three mortgage loans by the
same lender in the aggregate amount of $10,757,500 which are collateralized by
deeds of trust on the three rental properties. The notes bear interest at a rate
of 7.53%. Principal and interest are payable by the Partnership in monthly
installments of $79,707. A balloon payment of approximately $9,492,902 and the

To the Partners
DFW Apartment Investors Limited Partnership
 
     We have audited the accompanying balance sheets of DFW Apartment Investors
Limited Partnership as of December 31, 1996, and 1995, and the related
statements of income, partners' capital and cash flows for the years then ended.
These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on the financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of DFW Apartment Investors
Limited Partnership as of December 31, 1996, and 1995, and the results of its
operations, changes in partners' capital and cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     DFW Apartment Investors Limited Partnership (the "Partnership") was formed
April 25, 1990 under the laws of the State of Delaware for the purposes of
acquiring, renovating, operating and otherwise dealing with certain residential
apartments located in the Dallas/Fort Worth, Texas metropolitan area. The
Partnership will terminate on December 31, 2040, or earlier upon the occurrence
of certain events specified in the Partnership Agreement.
 
     The general partner of the Partnership is Winthrop Financial Associates, a
Maryland limited partnership ("WFA"). WFC Realty Co., Inc., a Massachusetts
corporation ("WFC Realty"), a wholly-owned subsidiary of WFA, was the initial
limited partner of the partnership and withdrew as limited partner upon the
first admission of investors. The partnership sold 206 limited partnership units
at $100,000 per unit.
 
     In accordance with the Partnership Agreement, losses and cash flow shall be
allocated 99% to investor limited partners and 1% to WFA; income shall be
allocated to the partners in proportion to the cash available for distribution
distributable to the partners. If there is no such cash available for
distribution, income will be allocated 95% to limited partners and 5% to WFA.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with generally accepted accounting principles.
 
  Rental Property
 
     Rental property is carried at cost. Depreciation is provided for in amounts
sufficient to relate the cost of depreciable assets to operations over their
estimated service lives by use of the straight-line method for financial
reporting purposes. For income tax purposes, accelerated lives and methods are
used.
 
  Deferred Costs
 
     Deferred costs are amortized using the straight-line method over the term
of the related agreement.
 
  Income Taxes
 
     No provision will be made for federal, state or local income taxes in the
financial statements of the Partnership. Partners will be required to report on
their tax returns their allocable shares of income, gains, losses, deductions
and credits of the Partnership.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the partnership and
tenants of the properties are operating leases.

  Cash Equivalents
 
     For purposes of the statement of cash flows, the partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents. The carrying amount of $528,585 approximates fair value because of
the short maturity of this investment.
 
NOTE B -- ACQUISITION OF THE PROPERTIES
 
     The Partnership acquired three separate residential apartment complexes
(the "Properties") in 1990 for an aggregate purchase price of $14,013,732. The
purchase represents an aggregate of 707 market-rate rental apartments in the
Dallas, Texas area.
 
     On June 8, 1990, the Partnership acquired Heather Ridge Apartments for
$5,104,350. On August 16, 1990 and September 19, 1990, the Partnership acquired
Oak Forest Apartments and Summit on Post Oak Apartments for $4,409,382 and
$4,500,000, respectively. The purchases were financed by a loan from Citibank.,
N.A. and an advance from WFA.
 
NOTE C -- MORTGAGES PAYABLE
 
     On April 15, 1996, the Partnership obtained three mortgage loans by the
same lender in the aggregate amount of $10,757,500 and are collateralized by
deeds of trust on the rental properties. The notes bear interest at a rate of
7.53%. Principal and interest are payable by the partnership in monthly
installments of $79,707. A balloon payment of approximately $9,492,902 and the
accrued interest is payable in full on May 1, 2003.
 
     Under agreements with the mortgage lender, the Partnership is required to
make monthly escrow deposits for taxes and insurance.
 
     The liability of the Partnership under the mortgage notes are limited to
the underlying value of the real estate collateral plus other amounts deposited
with the lender.
 
     Aggregate annual maturities of the mortgage payable over each of the next
five years are as follows:

NOTE D -- MORTGAGE RESERVES HELD IN ESCROW
 
     The Partnership has set up various reserve escrows with the Mortgage Lender
in connection with the Mortgage Loan.
 
     The Replacement Reserve in the amount of $368,782 and $0 at December 31,
1996 and 1995 secures the Partnership's agreement to undertake certain
improvements to the Property over the life of the mortgage loan. The amount of
this Reserve will be reduced as improvements are completed.
 
     An escrow for taxes and insurance has been set up under the Mortgage
Agreement. All taxes and insurance will be paid by the Mortgage Lender out of
these escrow accounts. The amounts held in escrow for insurance and taxes at
December 31, 1996 and 1995 is $399,027 and $0.
 
     The Mortgage Lender has the right to draw upon these escrows in the event
that the Partnership defaults in the performance of its obligations under the
Mortgage Loan, including its obligations to pay principal and

     The Partnership has incurred charges and commitments to companies
affiliated with the general partner. Related party transactions with WFA and its
affiliates include the following:
 
     The Partnership pays to an affiliate of WFA an annual property management
fee equal to 5% of gross operating revenues for the properties. Fees of $195,660
and $186,505 were charged to operations during the years ended December 31, 1996
and December 31, 1995, respectively.
 
     The Partnership pays to WFA an annual administration and investor service
fee of $40,000. This fee increased 5% annually from 1991 to 1995, and commencing
in 1996 the fee is increased 6% annually. Fees of $54,114 and $51,051,
respectively, were charged to operations during the years ended December 31,
1996 and 1995, respectively.
 
NOTE F -- CONCENTRATION OF CREDIT RISK

held by the Mortgage Lender. The account is insured by the Federal Deposit
Insurance Corporation up to $100,000 an account. The uninsured portion of this

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   1598
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1599
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     DFW Residential Investors Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1604
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1605
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tending units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $1,400 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $          per year on the number of
     Tax-Deferral   % Preferred OP Units, or distributions of $       per year
     on the number of Tax-Deferral Common OP Units, that you would receive in an
     exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income
 
                                       S-3
<PAGE>   1606
 
     tax purposes, as a partial sale of such units for cash, and as a partial
     tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration of $          consideration
     is fair. However, your units are not listed on any national securities
     exchange nor quoted on the NASDAQ System, and there is no established
     trading market for your units. Secondary sales activity for the units has
     been limited and sporadic. Your general partner does not monitor or
     regularly receive or maintain information regarding the prices at which
     secondary sale transactions in the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   1607
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1610
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code.
 
     The particular tax consequences to you of the exchange will depend upon a
number of factors related to your individual tax situation, including your tax
basis in your units, whether you dispose of all of your units in your
partnership, and whether the "passive loss" rules apply to your investments.
Because the income tax consequences of an exchange of units will not be the same
for everyone, you should consult your tax advisor before determining whether to
tender your units pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   1611
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   1612
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   1613
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11

authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 11.40% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   1615
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

operations substantially as they are currently being conducted. We do not have

actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making

COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
 
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions, liquidity and
transfer and redemption rights. See "Comparison of Preferred OP Units and Class
I Preferred Stock" for a chart highlighting such differences.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   1618
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, the general partner of your partnership is entitled to fees for
its services as general partner while the general partner of the AIMCO Operating
Partnership is not entitled to such fees.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of $25,000 beginning in 1990 and increasing annually at a rate of 5%
beginning in 1991 from your partnership and may receive reimbursement for
expenses generated in its capacity as general partner. The property manager
which received management fees of $125,608 in 1996, $129,884 in 1997 and $68,056
for the first six months of 1998. We have no current intention of changing the
fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. DFW Residential Investors Limited
Partnership is a Delaware limited partnership which was formed on January 11,
1990 for the purpose of owning and operating a small number of apartment
properties located in Euless, Texas and North Arlington, Texas, known as "Hunt
Club Apartments" and "Riverbend Village Apartments," respectively. In 1990, it
completed a private placement of units that raised net proceeds of approximately
$13,600,000. Hunt Club and consists of 204 apartment units and Riverbend Village
Apartments consists of 201 apartment units. Your partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now an affiliate of ours. Pursuant to the
management agreement between the property manager and your partnership, the
property manager operates your partnership's property, establishes rental
policies and rates and directs marketing activities. The property manager also
is responsible for maintenance, the purchase of equipment and supplies, and the
selection and engagement of all vendors, suppliers and independent contractors.
The property manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2040, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage notes outstanding on "Hunt Club Apartments" of $3,342,334 and
on "River Bend Apartments" of $3,716,129, payable to AMI Capital, which bear
interest at a rate of 7.61%. The mortgage debt is due December 2002. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     minimum annual provision for capital replacements of $300 per owned
     apartment unit.

     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be

     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated

     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1629
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1630
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the year ended December 31, 1997 were $1,400 per unit. This is
equivalent to distributions of $          per year on the number of Tax-Deferral
  % Preferred OP Units, or distributions of $       per year on the number of
Tax-Deferral Common OP Units, that you would receive in an exchange for each of
your partnership's units. Therefore, distributions with respect to the Preferred
OP Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own an 11.40% limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   1632
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
                                      S-30
<PAGE>   1633
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1635
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1636
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   1637
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   1638
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   1640
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

units tendered, and may terminate or amend the offer if at any time from or

     become aware of any facts relating to your partnership, its indebtedness or
     its operations which, in the sole judgment of the AIMCO Operating

                                      S-38

     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or

<PAGE>   1642
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced
     or publicly proposed to be made by another person or "group" (as defined in
     Section 13(d)(3) of the Securities Exchange Act of 1934), or it shall have

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   1643
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   1645
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   1646
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   1648
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   1653
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   1654
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   1656
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   1657
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units the $2.25, and distributions with respect to your units for
     the year ended December 31, 1997 were $1,400. This is equivalent to
     distributions of $          per year on the number of Tax-Deferral   %
     Preferred OP Units, or distributions of $       per year on the number of
     Tax-Deferral Common OP Units, that you would receive in an exchange for
     each of your partnership's units. Therefore, distributions with respect to
     the Preferred OP Units and Common OP Units that we are offering are
     expected to be        , immediately following our offer, than the
     distributions with respect to your units. See "Comparison of Ownership of
     Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   1658
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

apartment properties, the manner in which your partnership's property is sold
and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Price............................................    $

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
                                      S-59
<PAGE>   1662
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of $25,000 beginning in 1990 and increasing annually at a rate of 5%
beginning in 1991 from your partnership and may receive reimbursement for
expenses generated in its capacity as general partner. The property manager
received management fees of $125,608 in 1996, $129,884 in 1997 and $68,056 for
the first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     DFW Residential Investors Limited Partnership is a Delaware limited
partnership which raised net proceeds of approximately $13,600,000 in 1990
through a private offering. The promoter for the private offering of your
partnership was Winthrop Securities Co., Inc. Insignia acquired your partnership
in November 1997. AIMCO acquired Insignia in October, 1998. There are currently
a total of 130 limited partners of your partnership and a total of 136 units of
your partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
small number of apartment properties described below. Your partnership has no
employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on January 11, 1990 for the purpose of owning
and operating a small number of apartment properties located in Euless, Texas
and North Arlington, Texas, known as "Hunt Club Apartments" and "Riverbend
Village Apartments," respectively. There are 204 apartment units in "Hunt Club
Apartments" consisting of 120 one-bedroom apartments, 75 two-bedroom apartments
and 9 three-bedroom apartments. The total rentable square footage is 175,780
square feet and the average annual rent per apartment unit is $6,904. "River
Bend Apartments" has 201 apartment units. There are 120 one-bedroom apartments
and 81 two-bedroom apartments. The total rentable square footage is 151,799
square feet. The average annual rent per apartment unit is $5,861.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $125,608, $129,884 and $68,056, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2040
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,

December 31, 1996 compared to $144,085 for the year ended December 31, 1995, an

equivalents. Your partnership's principal demands for liquidity include normal

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable for damages or
otherwise to your partnership or any limited partner for any acts performed or
any failure to act by any of them if they determined, in good faith, that such
acts or failure to act was in the best interests of your partnership, and such
course of conduct did not constitute negligence or misconduct on the part of
such person. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest."
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss, damage, liability, cost or expense sustained
by it or them in connection with your partnership, provided that such loss,
damage, liability, cost or expense was not the result of negligence or
misconduct by such person. However, neither the general partner nor any
affiliate will be indemnified for any loss, damage or cost resulting from the
violation of any Federal or state securities laws in connection with the sale of
units unless (i) there has been a successful adjudication on the merits of each
count involving the securities law violations, (ii) such claims have been
dismissed with prejudice on the merits by a court of competent jurisdiction or
(ii) or court of competent jurisdiction approves a settlement of such claims. In
such claim for indemnification for Federal or state securities law violation,
the party seeking indemnification must place before the court the position of
the SEC and any other applicable regulatory agency with respect of the issue of
indemnification for securities law violations. Any such indemnity provided shall
be paid, from and only to the extent of, partnership assets. As part of its
assumption of liabilities in the consolidation, AIMCO will indemnify the general
partner of your partnership and their affiliates for periods prior to and
following the consolidation to the extent of the indemnity under the terms of
your partnership's agreement of limited partnership and applicable law.
 
     No partnership funds will be used to purchase any insurance that insures
any party against any liability for which indemnification is not available
pursuant to your partnership's agreement of limited partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale

     transactions (excluding transactions believed to be between related
parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     AIMCO currently owns an 11.40% limited partnership interest in your
partnership. Except as described above, neither AIMCO, nor, to the best of its
knowledge, any of its affiliates, (i) beneficially own or have a right to
acquire any units, (ii) have effected any transaction in the units, or (iii)
have any contract, arrangement, understanding or relationship with any other
person with respect to any securities of your partnership, including, but not
limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of DFW Residential
Investors Limited Partnership as of June 30, 1998 and for the six months then
ended have been prepared in accordance with generally accepted accounting
principles for interim financial information. Accordingly, they do not include
all the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments considered necessary for a fair presentation have been included and
all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
DFW Residential Investors Limited Partnership
 
     We have audited the accompanying balance sheets of DFW Residential
Investors Limited Partnership as of December 31, 1997 and 1996, and the related
statements of income, partners' capital and cash flows for the years then ended.
These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of DFW Residential Investors
Limited Partnership as of December 31, 1997 and 1996, and the results of its
operations, changes in partners' capital and its cash flows for the years then
ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     DFW Residential Investors Limited Partnership (the "Partnership"), a
limited partnership, was formed on January 11, 1990 under the laws of the State
of Delaware for the purposes of acquiring, renovating, operating and otherwise
dealing with certain residential apartments located in the Dallas, Texas,
metropolitan area. The Partnership will terminate on December 31, 2040 or
earlier upon the occurrence of certain events specified in the partnership
agreement.
 
     The general partner of the Partnership is Winthrop Financial Associates, A
Limited Partnership, a Maryland limited partnership ("WFA"). WFC Realty Co.,
Inc., a Massachusetts Corporation ("WFC Realty"), a wholly-owned subsidiary of
WFA, was the initial limited partner of the Partnership and withdrew as a
limited partner upon the first admission of investors. The Partnership sold 136
limited partnership units at $100,000 per unit.
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with generally accepted accounting principles.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Investment in Real Estate
 
     Real estate is carried at cost. The Partnership provides for depreciation
of buildings, improvements and personal property on the straight-line method
over their estimated useful lives for financial reporting purposes. For income
tax purposes, accelerated methods and lives are used.
 
  Deferred Costs
 
     Deferred costs are capitalized and amortized using the straight-line method
over the term of the related agreement.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the Partnership and
tenants of the property are operating leases.
 
  Income Taxes
 
     No provision will be made for federal, state or local income taxes in the
financial statements of the Partnership. Partners will be required to report on
their tax returns their allocable shares of taxable income, gains, losses,
deductions and credits of the Partnership.
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the Partnership considers all
highly liquid investments with maturities of less than three months to be cash
equivalents.

  Reclassifications
 
     Certain reclassifications have been made in the accompanying financial
statements for 1996 in order to conform to the current year presentation.
 
NOTE B -- ACQUISITION OF THE PROPERTIES
 
     The Partnership acquired two separate residential apartment complexes (the
"Properties") in 1990 for an aggregate purchase price of $9,624,448. The
purchase represents an aggregate of 405 market-rate rental apartments in the
Dallas, Texas, metropolitan area.
 
     On January 12, 1990, the Partnership acquired The Hunt Club Apartments for
$5,351,851 and, on April 5, 1990, the Partnership acquired Riverbend Apartments
for $4,272,597. Both purchases were financed by a loan from W.F.A., which was
repaid during 1993.
 
NOTE C -- MORTGAGES PAYABLE
 
     On December 28, 1995, the Partnership obtained two mortgage loans from the
same lender in the aggregate amount of $7,318,515, and they are collateralized
by deeds of trust on the rental properties. The notes bear interest at a rate of
7.61%. Principal and interest are payable by the Partnership in monthly
installments of $54,608. A balloon payment of approximately $6,434,516 and the
accrued interest is payable in full on December 29, 2002.
 
     Under agreements with the mortgage lender, the Partnership is required to
make monthly escrow deposits for taxes and insurance.
 
     The liability of the Partnership under the mortgage notes is limited to the
underlying value of the real estate collateral plus other amounts deposited with
the lender.
 
     Aggregate annual maturities of the mortgages payable over each of the next
five years are as follows:

To the Partners of
DFW Residential Investors Limited Partnership
 
     We have audited the accompanying balance sheets of DFW Residential
Investors Limited Partnership as of December 31, 1995 and 1994, and the related
statements of income, partners' capital and cash flows for the years then ended.
These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of DFW Residential Investors
Limited Partnership as of December 31, 1995 and 1994, and the results of its
operations, changes in partners' capital and its cash flows for the years then
ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     DFW Residential Investors Limited Partnership (the "Partnership"), a
limited partnership, was formed on January 11, 1990 under the laws of the State
of Delaware for the purposes of acquiring, renovating, operating and otherwise
dealing with certain residential apartments located in the Dallas, Texas
metropolitan area. The Partnership will terminate on December 31, 2040 or
earlier upon the occurrence of certain events specified in the Partnership
Agreement.
 
     The general partner of the Partnership is Winthrop Financial Associates, A
Limited Partnership, a Maryland limited partnership ("WFA"). WFC Realty Co.,
Inc., a Massachusetts Corporation ("WFC Realty"), a wholly-owned subsidiary of
WFA, was the initial limited partner of the Partnership and withdrew as a
limited partner upon the first admission of investors. The partnership sold 136
limited partnership units at $100,000 per unit.
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with generally accepted accounting principles.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Investment in Rental Property
 
     Real estate is carried at cost. The Partnership provides for depreciation
of buildings and improvements on the straight-line method over their estimated
useful lives for financial reporters purposes. For income tax purposes,
accelerated methods and lives are used.
 
  Deferred Costs
 
     Deferred costs are capitalized and amortized using the straight-line method
over the term of the related agreement as discussed in Note F.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the partnership and
tenants of the property are operating leases.
 
  Income Taxes
 
     No provision will be made for federal, state or local income taxes in the
financial statements of the Partnership. Partners will be required to report on
their tax returns their allocable shares of taxable income, gains, losses,
deductions and credits of the Partnership.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents. The carrying amount of $842,997 approximates fair value because of
the short maturity of this instrument.
 
NOTE B -- ACQUISITION OF THE PROPERTIES
 
     The Partnership acquired two separate residential apartment complexes (the
"Properties") in 1990 for an aggregate purchase price of $9,624,448. The
purchase represents an aggregate of 405 market-rate rental apartments in the
Dallas, Texas metropolitan area.
 
     On January 12, 1990, the Partnership acquired The Hunt Club Apartments for
$5,351,851 and on April 5, 1990 the Partnership acquired Riverbend Apartments
for $4,272,597. Both purchases were financed by a loan from WFA, which was
repaid during 1993.
 
NOTE C -- MORTGAGES PAYABLE
 
     On December 28, 1995, the partnership obtained two mortgage loans from the
same lender in the aggregate amount of $7,318,515 and are collateralized by
deeds of trust on the rental properties. The notes bear interest at a rate of
7.61%. Principal and interest are payable by the partnership in monthly
installments of $54,608. A balloon payment of approximately $6,434,516 and the
accrued interest is payable in full on December 29, 2002.
 
     Under agreements with the mortgage lender, the partnership is required to
make monthly escrow deposits for taxes and insurance.
 
     The liability of the partnership under the mortgage notes are limited to
the underlying value of the real estate collateral plus other amounts deposited
with the lender.
 
     The carrying amount of the partnerships long term debt approximates fair
value.
 
     Aggregate annual maturities of the mortgages payable over each of the next
five years are as follows:

NOTE D -- DUE TO AFFILIATE

upon the completion of the syndication. The remaining balance was paid during
1994.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   1705
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1706
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Four Quarters Habitat Apartments Associates, Ltd.. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1711
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1712
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid $0 per unit for the six months ended June 30, 1998.
     We will pay fixed quarterly distributions of $               per unit on
     the Tax-Deferral   % Preferred OP Units before any distributions are paid
     to holders of Tax-Deferral Common OP Units. We pay quarterly distributions
     on the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   1713
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our consideration is fair. However, your units are
     not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   1714
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1717
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   1718
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   1719
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   1720
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   1721
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources. Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your
 
                                      S-12
<PAGE>   1722
 
     partnership without the offer would deny you and your partners the benefits
     that your general partner expects to result from the offer. For example, a
     partner of your partnership would have no opportunity for liquidity unless
     he were to sell his units in a private transaction. Any such sale would
     likely be at a very substantial discount from the partner's pro rata share
     of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
                                      S-13
<PAGE>   1723
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any combination
of such forms of consideration for your units. The offer is made upon the terms

     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   1725
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 28.58%
of the remaining Cash Flow after distributions of 12% per annum of each limited
partner's capital contribution has been made to each limited partner and may
receive reimbursement for expenses generated in its capacity as general partner
from your partnership. The property manager received management fees of $57,825
in 1996, $57,535 in 1997 and $27,845 for the first six months of 1998. We have
no current intention of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Four Quarters Habitat Apartments
Associates, Ltd. is a Florida limited partnership which was formed on May 11,
1983 for the purpose of owning and operating a single
 
                                      S-18
<PAGE>   1728
 
apartment property located in Miami, Florida, known as "Four Quarters Habitat".
In 1983, it completed a private placement of units that raised net proceeds of
approximately $8,550,000. Four Quarters Habitat consists of 336 apartment units.
Your partnership has no employees.
 
     Property Management. Since December 1993, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2030, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $10,636,937, payable to LP Commercial
Conduit Mfg. Trust, which bears interest at a rate of 9.84%. The mortgage debt
is due in October 2001. Your partnership's agreement of limited partnership also
allows your general partner to lend funds to your partnership. Currently, the
general partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1736
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1737
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$       with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of $0
with respect to your units, distributions with respect to the Preferred OP Units
and Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO to
negative from stable to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   1738
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the proposed Series I Preferred Stock and confirmed its previous
ratings related to AIMCO's preferred stock and debt in its shelf registration
statement. Moody's indicated that its rating action continues to reflect AIMCO's
increasing leveraged profile, including high levels of secured debt and
preferred stock, limited financial flexibility and integration risks resulting
from the merger with Insignia. Moody's also noted AIMCO's high levels of
encumbered properties and material investments in loans to highly leveraged
partnerships in which AIMCO owns a general partnership interest.

                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
                                      S-29
<PAGE>   1739
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent the limited
partners holding of at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership may require funding from its partners. Continuation of
its operations may be dependent on additional funding from partners or from
other sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership
 
                                      S-30

interest in the property owned by your partnership while providing you and other
investors with an opportunity to retain or liquidate your investment or to
invest in the AIMCO Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units. Your Partnership has
       not paid any distributions on your units since the inception of your
       partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your units
       since the inception of your partnership. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1742
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1743
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

 Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation
 to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   1745
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   1746
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   1747
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     that any debt of your partnership or any of its subsidiaries secured by any

        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   1750
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $       .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   1752
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   1753
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   1760
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   1761
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity Securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value, the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   1763
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   1764
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.

     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on

        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $       with
     respect to the Preferred OP Units, current annualized distributions of
     $2.25 with respect to the Common OP Units and the 1998 distributions of
     $0.00 with respect to your units, distributions with respect to the
     Preferred OP Units and Common OP Units being offered are expected to be
            , immediately following our offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   1765
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local
 
                                      S-58
<PAGE>   1768
 
     market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect
 
                                      S-59
<PAGE>   1769
 
     the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the partnership's property or
other balance sheet assets and liabilities or other information reviewed between
the date of such information provided and the date of the Fairness Opinion; that
your partnership, AIMCO, and the management of the partnership's property are
not aware of any information or facts that would cause the information supplied
to Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with
respect to your partnership. In addition, Stanger is entitled to reimbursement
for reasonable legal, travel and out-of-pocket expenses incurred in making the

Federal securities laws. No portion of Stanger's fee is contingent upon
consummation of the offer or the content of Stanger's opinion. Stanger has

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 28.58%
of the remaining Cash Flow after distributions of 12% per annum of each limited
partner's capital contribution has been made to each limited partner and may
receive reimbursement for expenses generated in its capacity as general partner
from your partnership. The property manager received management fees of $57,825
in 1996, $57,535 in 1997 and $27,895 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Four Quarters Habitat Apartments Associates, Ltd. is a Florida limited
partnership which raised net proceeds of approximately $8,550,000 in 1983
through a private offering. The promoter for the private offering of your
partnership was Van Kampen Merrit, Inc. Insignia acquired your partnership in
December 1993. AIMCO acquired Insignia in October, 1998. There are currently a
total of 100 limited partners of your partnership and a total of 98 units of
your partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
single apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 11, 1983 for the purpose of owning and
operating a single apartment property located in Miami, Florida, known as "Four
Quarters Habitat." Your partnership's property consists of 336 apartment units.
There are 80 one-bedroom apartments and 256 two-bedroom apartments. The total
rentable square footage of your partnership's property is 364,480 square feet.
Your partnership's property had an average occupancy rate of approximately
95.54% in 1996 and 95.54% in 1997. The average annual rent per apartment unit is
approximately $8,357.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1993, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $57,825, $57,535 and $27,845, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2030
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $10,636,937, payable to LP Commercial Conduit Mfg. Trust, which
bears interest at a rate of 9.84%. The mortgage debt is due in October 2001.
Your partnership's agreement of limited partnership also allows the general
partner of your partnership to lend funds to your partnership. Currently, the
general partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $267,159 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership is not
liable to your partnership or any limited partner for loss or damage that may be
caused by any act performed by it or any failure to act if such acts were done
in good faith and in accordance with sound business practices and in accordance
with the terms of your partnership's agreement of limited partnership. As a
result, unitholders might have a more limited right of action in certain
circumstances than they would have in the absence of such a provision in your
partnership's agreement of limited partnership. The general partner of your
partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any claim, loss, damage, liability, action or expense
sustained by it or them as a result of any act or omission done in good faith
and in accordance with sound business practices and in accordance with the terms
of your partnership's agreement of limited partnership, provided that such acts
do not constitute fraud, bad faith, breach of fiduciary duty, gross negligence
or intentional misconduct. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partner of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has paid no distributions in the last five years. The
original cost per unit was $251,471.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Four Quarters Habitat
Apartments Associates, LTD. as of June 30, 1998 and for the six months ended
June 30, 1998 and 1997 have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     It should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                            AIMCO Properties, L.P.

1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   1797
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1798
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Georgetown of Columbus Associates, L.P. For each unit that you tender, you
     may choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner (the "general partner") of
     your partnership and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1803
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1804
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0 per unit for the six months ended
     June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   1805
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   1806
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1809
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   1810
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   1811
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   1812
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   1813
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently do not own any limited partnership interest in
your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   1814
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.

     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other

contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a

wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will

       delay acceptance of, and payment for, any tendered units;
 
                                      S-14
<PAGE>   1816
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will also pay all costs and expenses of printing and mailing
this Prospectus Supplement and the legal fees and expenses in connection
therewith. We will also pay the fees of Stanger for providing the fairness
opinions for the offer. We estimate that our total costs and expenses in making
the offer (excluding the purchase price of the units payable to you and your
partners) will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are

$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much
 
                                      S-16
<PAGE>   1818
 
     of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you, from a financial point of view. Stanger did not
analyze the fairness of the number of Tax-Deferral  % Preferred OP Units or
Tax-Deferral Common OP Units that we are offering for your units.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.

<PAGE>   1819
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of 1% of the gross collected income of your partnership's property
for its services as general partner of your partnership and may receive
reimbursement for expenses generated in that capacity from your partnership. The
property manager received management fees of $51,864 in 1996, $55,922 in 1997
and $28,257 for the first six months of 1998. We have no current intention of
changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Georgetown of Columbus Associates, L.P.
is a Delaware limited partnership which was formed on October 5, 1983 for the
purpose of owning and operating a single apartment property located in Columbus,
Ohio, known as "Georgetown of Columbus Apartments." In 1983, it completed a
private placement of units that raised net proceeds of approximately $2,500,000.
Georgetown of Columbus Apartments consists of 150 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase
 
                                      S-18
<PAGE>   1820
 
of equipment and supplies, and the selection and engagement of all vendors,
suppliers and independent contractors. The property manager is affiliated with
us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2026, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,706,761, payable to FNMA, which bears
interest at a rate of 7.60%. The mortgage debt is due in November 2002. Your
partnership also has a second mortgage note outstanding of $131,718, on the same
terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration, from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1828
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     The summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1829
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $0.00. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
                                      S-28
<PAGE>   1830
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   1831
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units. However, one
       class of outstanding Partnership Preferred Units has prior distribution
       rights and the Tax-Deferral   % Preferred OP Units rank equal to six
       other outstanding classes of Partnership Preferred Units.
 
                                      S-30
<PAGE>   1832
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your units
       since the inception of your partnership. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1834
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1835
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   1836
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   1837
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   1838
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   1842
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   1843
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
                                      S-42
<PAGE>   1844
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income gain will be made to any
holder of Junior Units upon the liquidation, dissolution or winding up of the
AIMCO Operating Partnership. If, upon any liquidation, dissolution or winding up
of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have
                                      S-43
<PAGE>   1845
 
     been made in full to the holders of Preferred OP Units and any Parity Units
to enable them to receive their Liquidation Preference, any Junior Units shall
be entitled to receive any and all assets remaining to be paid or distributed,
and the holders of the Preferred OP Units and any Parity Units shall not be
entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP

applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   1852
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   1853
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   1855
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.

     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June, 1998 were $0.00. Therefore, distributions with
     respect to the Preferred OP Units and Common OP Units that we are offering
     are expected to be        , immediately following our offer, than the
     distributions with respect to your units. See "Comparison of Ownership of
     Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   1857
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
                                      S-59
<PAGE>   1861
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of 1% of the gross collected income from your partnership's property
and may receive reimbursement for expenses generated in that capacity from your
partnership. The property manager received management fees of $51,864 in 1996,
$55,922 in 1997 and $28,257 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Georgetown of Columbus Associates, L.P. is a Delaware limited partnership
which raised net proceeds of approximately $2,500,000 in 1983 through a private
offering. The promoter for the private offering of your partnership was
Jacques-Miller. Insignia acquired your partnership in December 1991. AIMCO
acquired Insignia in October, 1998. There are currently a total of 53 limited
partners of your partnership and a total of 25 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on October 5, 1983 for the purpose of owning
and operating a single apartment property located in Columbus, Ohio, known as
"Georgetown of Columbus Apartments." Your partnership's property consists of 150
apartment units. There are 9 one-bedroom apartments, 130 two-bedroom apartments,
10 three-bedroom apartments and 1 four-bedroom apartment. The total rentable
square footage of your partnership's property is 128,892 square feet. Your
partnership's property had an average occupancy rate of approximately 95.33% in
1996 and 95.33% in 1997. The average annual rent per apartment unit is
approximately $7,121.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $51,864, $55,922 and $28,257, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2026
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,706,761, payable to FNMA, which bears interest at a rate of
7.60%. The mortgage debt is due in November 2002. Your partnership also has a
second mortgage note outstanding of $131,718, on the same terms as the current
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
financial statements of your partnership included herein.
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Income
 
     Your partnership recognized net income of $73,310 for the six months ended
June 30, 1998, compared to $80,920 for the six months ended June 30, 1997. The
decrease in net income of $7,610, or 9.40% was primarily the result of an
increase in operating expenses offset by an increase in total revenue. These
factors are discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$560,900 for the six months ended June 30, 1998, compared to $550,891 for the
six months ended June 30, 1997, a increase of $10,009, or 1.82%.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $208,409 for the
six months ended June 30, 1998, compared to $206,265 for the six months ended
June 30, 1997, an increase of $2,144 or 1.04%. Management expenses totaled
$28,257 for the six months ended June 30, 1998, compared to $27,941 for the six
months ended June 30, 1997, an increase of $316, or 1.13%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $19,990 for the six months
ended June 30, 1998 compared to $17,414 for the six months ended June 30, 1997,
an increase of $2,576 or 14.79%. This increase was primarily due to an increase
in general partner reimbursements.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $164,465 for the six months ended June 30, 1998, compared to
$151,529 for the six months ended June 30, 1997, an increase of $12,936, or
8.54%.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized net income of $55,874 for the year ended
December 31, 1997, compared to a net loss of $29,605 for the year ended December
31, 1996. The increase in net income of $ 85,479, or 288.73% was primarily the
result of increasing rental revenue while maintaining stable operating expenses.
These factors are discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,120,563 for the year ended December 31, 1997, compared to $1,045,905 for the
year ended December 31, 1996, an increase of $74,658, or 7.14%. This increase
was primarily the result of an increase in occupancy and rental rates.

the year ended December 31, 1997, compared to $51,864 for the year ended

an increase in rental revenues as management fees are calculated based on a
percentage of revenue.

December 31, 1997 compared to $38,664 for the year ended December 31, 1996, a

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $24,777 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership will
not incur any liability to your partnership or any limited partner for any
mistakes or errors in judgment or for any acts or omission believed by the
general partner in good faith to be within the scope of authority conferred upon
it by your partnership agreement. As a result, unitholders might have a more
limited right of action in certain circumstances than they would have in the
absence of such a provision in your partnership's agreement of limited
partnership. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest".
 
     Your partnership will, to the extent permitted by law, indemnify and save
harmless the general partner against and from any personal loss, liability
(including attorneys' fees) or damage incurred by it as the result of any act or
omission in its capacity as general partner unless such loss, liability or
damage results from gross negligence or willful misconduct by the general
partner. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not made a distribution within the last five years.
The original cost per unit was $25,510.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or
 
                                      S-76
<PAGE>   1878
 
voting thereof, joint ventures, loan or option arrangements, puts or calls,
guarantees of loans, guarantees against loss or the giving or withholding of
proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the compensation paid to the property
manager or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.
 
     Below is an itemized statement of the estimated expenses incurred and to be

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Burgundy Court Limited
as of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Georgetown of Columbus Associates, Limited:
 
     We have audited the accompanying balance sheets of Georgetown of Columbus
Associates, Limited as of December 31, 1997 and 1996, and the related statements
of operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Georgetown of Columbus
Associates, Limited as of December 31, 1997 and 1996, and the results of its
operations and its cash flows for the years then ended, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Georgetown of Columbus Associates, Limited (the "Partnership") was
organized as a limited partnership under the laws of the State of Delaware
pursuant to a Limited Partnership Agreement and Certificate of Limited
Partnership dated October 13, 1983. The Partnership owns and operates a 150 unit
apartment complex, Georgetown of Columbus Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 10 to 25 years and the personal
property assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$63,389 and $76,344, respectively, which are amortized over the term of the
related borrowing. Deferred loan costs are presented net of accumulated
amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the

obligations.

General Partners
Georgetown of Columbus Associates, Limited:
 
     We have audited the accompanying balance sheets of Georgetown of Columbus
Associates, Limited as of December 31, 1996 and 1995, and the related statements
of operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Georgetown of Columbus
Associates, Limited as of December 31, 1996 and 1995, and the results of its
operations and its cash flows for the years then ended, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Georgetown of Columbus Associates, Limited (the "Partnership") was
organized as a limited partnership under the laws of the State of Delaware
pursuant to a Limited Partnership Agreement and Certificate of Limited
Partnership dated October 13, 1983. The Partnership owns and operates a 150 unit
apartment complex, Georgetown of Columbus Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 10 to 25 years and the personal
property assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 consist of deferred loan costs
which are amortized over the term of the related borrowing. Deferred loan costs
are presented net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.

     The principal balance of the mortgage notes may not be prepaid, in whole or
in part, prior to November 15, 1997. Thereafter the principal may be prepaid in
whole upon payment of a penalty of the greater of one percent of the unpaid
principal balance at the time of prepayment or the present value of the excess
of interest which would be incurred at the stated rate under the notes over the
interest which would be incurred at the Treasury constant maturity for U.S.
Government obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership has no administrative or management employees and is
dependent on the Managing General Partner and its affiliates for the management
and administration of all partnership activities. The Partnership is obligated
to pay a property management fee equal to 5% of gross monthly collections. In
addition to the management fee, the partnership agreement provides for payments
to affiliates of a partnership administration fee and reimbursement of certain
expenses incurred by affiliates on behalf of the Partnership.

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
                                       A-1
<PAGE>   1902
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   1903
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49   states, the District of Columbia and
     Puerto Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million,
     total debt of $1,314 million and stockholders' equity of $1,394 million. On
     a pro forma basis, giving effect to our recently completed merger with
     Insignia Financial Group, Inc. and related transactions, as of June 30,
     1998, AIMCO had total assets of $3,972 million, total debt of $1,626
     million and stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner (the "general partner") of
     your partnership and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   1908
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   1909
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $385 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to a distribution of $     per year on the number of
     Tax-Deferral   % Preferred OP Units, or distributions of $     per year on
     the number of Tax-Deferral Common OP Units, that would receive in an
     exchange of your partnership units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   1911
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit date compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   1914
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   1915
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   1916
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service revised its outlook for the ratings of AIMCO from
stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
                                      S-10
<PAGE>   1917
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland
 
                                      S-11
<PAGE>   1918
 
corporation, we are subject to various Maryland laws which may have the effect
of discouraging offers to acquire us and of increasing the difficulty of
consummating any such offers, even if our acquisition would be in our
stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently do not own any limited partnership interest in
your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private
 
                                      S-12
<PAGE>   1919
 
     transaction. Any such sale would likely be at a very substantial discount
     from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."
 
TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %

     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

(1) As of June 30, 1998
 
     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a
 
                                      S-16
<PAGE>   1923
 
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, unlike the AIMCO Operating Partnership's agreement of limited
partnership, your partnership's agreement of limited partnership does not limit
the liability of the general partners to your partnership or the limited
partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment,
 
                                      S-17
<PAGE>   1924
 
voting rights, distributions and liquidity and transferability/redemption. For
example, unlike the AIMCO OP Units, you have no redemption rights with respect
to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual management fee equal to the greater of an amount equal to 7.5% of the Net
Cash Flow or $10,000, payable monthly in addition to reimbursement for expenses
generated in its capacity as general partner. The property manager received
management fees of $80,878 in 1996, $83,502 in 1997 and $44,072 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. La Colina Partners, Ltd. is a California
limited partnership which was formed on January 1, 1993 for the purpose of
owning and operating a single apartment property located in Denton, Texas, known
as "La Colina Ranch Apartments." In 1983, it completed a private placement of
units that raised net proceeds of approximately $2,548,000. La Colina Ranch
Apartments consists of 264 apartment units. Your partnership has no employees.
 
     Property Management. Since November 1992, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new
 
                                      S-18
<PAGE>   1925
 
properties. Your partnership will terminate on December 31, 2023, unless earlier
dissolved. Your general partner has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period. An investment in your partnership is a finite life investment in which
partners receive regular cash distributions out of your partnership's
distributable cash flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $5,014,155, payable to FNMA, which bears
interest at a rate of 7.83%. The mortgage debt is due in October 2003. Your
partnership also has a second mortgage note outstanding of $163,710, on the same
terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   1933
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   1934
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of
$0.00 with respect to your units, distributions with respect to the Preferred OP
Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   1935
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   1936
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
                                      S-30
<PAGE>   1937
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   1939
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   1940
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   1941
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   1942
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   1943
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   1944
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     offer, (ii) seeks to make the purchase of, or payment for, some or all of

circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   1947
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   1949
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   1950
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   1951
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   1952
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the

shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             of Class I Preferred Stock. The redemption price for
                                                             the Class I Preferred Stock (other than any portion

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   1957
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   1958
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   1960
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   1961
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $ with
     respect to the Common OP Units and the 1998 distributions of $385 with
     respect to your units, distributions with respect to the Preferred OP Units
     and Common OP Units being offered are expected to be      , immediately
     following the offer, than the distributions with respect to your units.
     This is equivalent to a distribution of $     per year on the number of
     Tax-Deferral   % Preferred OP Units, or distributions of $     per year on
     the number of Tax-Deferral Common OP Units, that would receive in an
     exchange of your partnership units. See "Comparison of Ownership of Your
     Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   1962
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.

     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,

AIMCO concerning,
 
                                      S-59

     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the

transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual management fee equal to the greater of an amount equal to 7.5% of the Net
Cash Flow or $10,000, payable monthly in addition to reimbursement for expenses
generated in its capacity as general partner, which received management fees of
80,878 in 1996, 83,502 in 1997 and 44,072 for the first six months of 1998. The
AIMCO Operating Partnership has no current intention of changing the fee
structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     La Colina Partners, Ltd. is a California limited partnership which raised
net proceeds of approximately $2,548,000 in 1983 through a private offering. The
promoter for the private offering of your partnership was Angeles Properties,
Inc. Insignia acquired your partnership in November 1992. AIMCO acquired
Insignia in October, 1998. There are currently a total of 51 limited partners of
your partnership and a total of 52 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on January 1, 1993 for the purpose of owning
and operating a single apartment property located in Denton, Texas, known as "La
Colina Ranch Apartments." Your partnership's property consists of 264 apartment
units. There are 112 one-bedroom apartments and 152 two-bedroom apartments. The
total rentable square footage of your partnership's property is 194,304 square
feet. Your partnership's property had an average occupancy rate of approximately
98.11% in 1996 and 98.11% in 1997. The average annual rent per apartment unit is
approximately $6,054.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1992, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $80,878, $83,502 and $44,072, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2023
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $5,014,155, payable to FNMA, which bears interest at a rate of
7.83%. The mortgage debt is due in October 2003. Your partnership also has a
second mortgage note outstanding of $163,710, on the same terms as the current
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.

June 30, 1997
 
     Net Income

June 30, 1998, compared to $188,035 for the six months ended June 30, 1997, an
increase in net income of $7,592, or 4.04%. This increase was primarily the
result of a greater increase in revenue than in expenses. These factors are
discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$878,535 for the six months ended June 30, 1998, compared to $857,460 for the
six months ended June 30, 1997, an increase of $21,075, or 2.46%.
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $349,534 for the
six months ended June 30, 1998, compared to $310,583 for the six months ended
June 30, 1997, an increase of $38,951 or 12.54%. This increase is due primarily
to an increase in non-capitalizable exterior maintenance and landscaping.
Management expenses totaled $44,072 for the six months ended June 30, 1998,
compared to $42,375 for the six months ended June 30, 1997, an increase of
$1,697, or 4.00%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $17,115 for the six months
ended June 30, 1998 compared to $14,888 for the six months ended June 30, 1997,
an increase of $2,227 or 14.96%.
 
     Interest Expense

costs, totaled $203,517 for the six months ended June 30, 1998, compared to
$237,122 for the six months ended June 30, 1997, a decrease of $33,605, or
14.17%. The decrease was due to the partnership's note payable to Angeles
Acceptance pool being retired in the third quarter of 1997.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized net income of $285,242 for the year ended
December 31, 1997, compared to $120,051 for the year ended December 31, 1996.
The increase in net income of $165,191, or 137.60% was primarily the result of
an increase in revenues and a decrease in operating expenses. These factors are
discussed in more detail in the following paragraphs.

year ended December 31, 1997, compared to $799,570 for the year ended December
31, 1996, a decrease of $111,594 or 13.96%. This is due to a reduction in
non-capitalized exterior maintenance and landscaping. Management expenses
totaled $83,502 for the year ended December 31, 1997, compared to $80,878 for
the year ended December 31, 1996, an increase of $2,624, or 3.24%.

December 31, 1997 compared to $53,865 for the year ended December 31, 1996, a
decrease of $14,799 or 27.47%. The decrease is primarily due to a decrease in
General Partner reimbursement fees.

costs, totaled $505,679 for the year ended December 31, 1997, compared to

received from tenants), contract services, turnover costs, repairs and

year ended December 31, 1996, compared to $606,324 for the year ended December

  Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $646,622 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Your partnership's agreement of
limited partnership does not limit the liability of the general partners to your
partnership or any limited partners for acts done in their capacity as general
partner. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest."
 
     Under your partnership's agreement of limited partnership, the general
partners of your partnership are indemnified for any loss or damage, including
legal fees and expenses and amounts paid in settlement, incurred by such parties
by reason of any act performed or omitted by such parties on behalf of your
partnership or in furtherance of your partnership's interest, provided that the
party sued will not be entitled to indemnification for losses sustained by
reason of their gross negligence, willful misconduct or breach of fiduciary
obligations. As part of its assumption of liabilities in the consolidation,
AIMCO will indemnify the general partner of your partnership and their
affiliates for periods prior to and following the consolidation to the extent of
the indemnity under the terms of your partnership's agreement of limited
partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The
original cost per unit was $49,000.

1998 (through June 30)......................................         0.00
</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES

includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in respect of its capacity as general partner of
your partnership as described in the following table:

any material difference in the compensation that would have been paid to the
general partner of your partnership, or the compensation paid to the property
manager or AIMCO and its affiliates.

     The AIMCO Operating Partnership expects that approximately $

          NOTES TO CONDENSED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of La Colina Partners,
Limited as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with the accounting basis for Federal income
tax reporting. Accordingly, they do not include all the information and
footnotes required by the accounting basis for Federal income tax reporting for
complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
La Colina Partners, Limited:
 
     We have audited the consolidated statement of assets, liabilities and
partners' deficit -- income tax basis of La Colina Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1997, and
the related consolidated statements of revenues and expenses and changes in
partners' deficit -- income tax basis and cash flows -- income tax basis for the
year then ended. These consolidated financial statements are the responsibility
of the partnership's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting La Colina Partners, Limited uses for Federal
income tax purposes, which is a comprehensive basis of accounting other than
generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of La Colina
Partners, Limited and its limited partnership interest as of December 31, 1997,
and the results of their operations and their cash flows for the year then
ended, on the basis of accounting described in Note A.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of La Colina
Partners, Limited (the "Partnership"), and its Limited Partnership interest in
La Colina Ranch Apartments, Limited (the "Project Partnership"). The Partnership
was organized solely to invest in the Project Partnership. The Project
Partnership owns and operates a 264 unit apartment complex, located in Denton,
Texas.
 
     The Partnership was organized as a California limited partnership on July
15, 1983. The Managing General Partner of the Partnership is Angeles Properties,
Inc. ("API"). The non-managing general partners, who also serve as non-managing
general partners of the Project Partnership, are the Elliott Family Partnership,
Ltd. (a California limited partnership) and the Elliott Accommodation Trust (a
California limited partnership). The general partners act as general partners in
other limited partnerships and are affiliates of Angeles Investment Properties,
Inc. ("AIPI"), the Project Partnership's managing general partner. Pursuant to
the terms of the Agreement and Amended Certificate of Limited Partnership (the
"Agreement"), the general partners have contributed $26,000 to the Partnership
for which they are entitled to a 2% interest in the operating profits, losses,
credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $2,548,000.
Pursuant to the terms of the Agreement, the limited partners will receive a 98%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership has made capital contributions to the Project Partnership
and is entitled to a 98% interest in the operating profits, losses, credits and
cash distributions of the Project Partnership. The Project Partnership's general
partners are entitled to the remaining 2% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership tax returns. The tax basis used differs from GAAP primarily because
on the tax basis (1) certain rental income received in advance is recorded as
income in the year received rather than in the year earned, (2) buildings and
related personal property are depreciated using the lives specified under the
accelerated cost recovery system ("ACRS") or the modified accelerated cost
recovery system ("MACRS") instead of over the estimated lives of the assets, (3)
syndication costs are carried at their original value, instead of being
amortized over the estimated life of assets, and (4) income is recorded at the
partnership level based on the partnership agreement and the Internal Revenue
Code instead of being recorded based solely on the percentage of ownership
interest.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property.
 
  Other Assets
 
     Other assets at December 31, 1997 include deferred loan costs of $122,974,
which are amortized over the term of the related borrowing. Deferred loan costs
are shown net of accumulated amortization. Also included in other assets at
December 31, 1997 are $333,392 of syndication fees which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 were $115,192 and consist
of a reserve escrow established with a portion of the proceeds of the loan. The
funds are used for certain repair work, debt service, expenses and property
taxes or insurance. The funds in the reserve escrow exceed the minimum balance
required to be maintained by the lender during the term of the loan.
 
NOTE C -- NOTES PAYABLE
 
     Notes payable at December 31, 1997 consist of the following:

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid principal
balance at the time of prepayment or the present value of the excess of interest
which would be incurred at the stated rate under the notes over the interest
which would be incurred at the Treasury constant maturity for U.S. Government
obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the general partners for the
management and administration of all partnership activities. The Project
Partnership is obligated to pay a property management fee equal to 5% of gross
monthly collections. In addition to the management fee, the partnership
agreement provides for payments of a partnership administration fee to general
partners and reimbursement of certain expenses incurred by general partners on
behalf of the Partnership and the Project Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
La Colina Partners, Limited:
 
     We have audited the consolidated statement of assets, liabilities and
partners' deficit -- income tax basis of La Colina Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1996, and
the related consolidated statement of revenues and expenses and changes in
partners' deficit -- income tax basis and cash flows -- income tax basis for the
year then ended. These consolidated financial statements are the responsibility
of the partnership's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting La Colina Partners, Limited uses for Federal
income tax purposes, which is a comprehensive basis of accounting other than
generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of La Colina
Partners, Limited and its limited partnership interest as of December 31, 1996,
and the results of their operations and their cash flows for the year then
ended, on the basis of accounting described in Note A.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                               DECEMBER 31, 1996
 
NOTE A  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of La Colina
Partners, Limited (the "Partnership"), and its Limited Partnership interest in
La Colina Ranch Apartments, Limited (the "Project Partnership"). The Partnership
was organized solely to invest in the Project Partnership. The Project
Partnership owns and operates a 264 unit apartment complex, located in Denton,
Texas.
 
     The Partnership was organized as a California limited partnership on July
15, 1983. The Managing General Partner of the Partnership is Angeles Properties,
Inc. ("API"). The non-managing general partners, who also serve as non-managing
general partners of the Project Partnership, are the Elliott Family Partnership,
Ltd. (a California limited partnership) and the Elliott Accommodation Trust (a
California limited partnership). The general partners act as general partners in
other limited partnerships and are affiliates of Angeles Investment Properties,
Inc. ("AIPI"), the Project Partnership's managing general partner. Pursuant to
the terms of the Agreement and Amended Certificate of Limited Partnership (the
"Agreement"), the general partners have contributed $26,000 to the Partnership
for which they are entitled to a 2% interest in the operating profits, losses,
credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $2,548,000.
Pursuant to the terms of the Agreement, the limited partners will receive a 98%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership has made capital contributions to the Project Partnership
and is entitled to a 98% interest in the operating profits, losses, credits and
cash distributions of the Project Partnership. The Project Partnership's general
partners are entitled to the remaining 2% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership tax returns. The tax basis used differs from GAAP primarily because
on the tax basis (1) certain rental income received in advance is recorded as
income in the year received rather than in the year earned, (2) buildings and
related personal property are depreciated using the lives specified under the
accelerated cost recovery system ("ACRS") or the modified accelerated cost
recovery system ("MACRS") instead of over the estimated lives of the assets, (3)
syndication costs are carried at their original value, instead of being
amortized over the estimated life of assets, and (4) income is recorded at the
partnership level based on the partnership agreement and the Internal Revenue
Code instead of being recorded based solely on the percentage of ownership
interest.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property.
 
  Other Assets
 
     Other assets at December 31, 1996 include deferred loan costs of $143,870,
which are amortized over the term of the related borrowing. Deferred loan costs
are shown net of accumulated amortization. Also included in other assets at
December 31, 1996 are $333,392 of syndication fees which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1996 were $110,457 and consist
of a reserve escrow established with a portion of the proceeds of the loan. The
funds are used for certain repair work, debt service, expenses and property
taxes or insurance. The funds in the reserve escrow exceed the minimum balance
required to be maintained by the lender during the term of the loan.
 
NOTE C -- NOTES PAYABLE
 
     Notes payable at December 31, 1996 consist of the following:

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
La Colina Partners, Limited:
 
     We have audited the consolidated statements of assets, liabilities and
partners' deficit -- income tax basis of La Colina Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1995 and
1994, and the related consolidated statements of revenues and expenses and
changes in partners' deficit -- income tax basis and cash flows -- income tax
basis for the years then ended. These consolidated financial statements are the
responsibility of the partnership's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting La Colina Partners, Limited uses for Federal
income tax purposes, which is a comprehensive basis of accounting other than
generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of La Colina
Partners, Limited and its limited partnership interest as of December 31, 1995
and 1994, and the results of their operations and their cash flows for the years
then ended, on the basis of accounting described in Note A.

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS --
                                INCOME TAX BASIS
                           DECEMBER 31, 1995 AND 1994
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of La Colina
Partners, Limited (the "Partnership"), and its Limited Partnership interest in
La Colina Ranch Apartments, Limited (the "Project Partnership"). The Partnership
was organized solely to invest in the Project Partnership. The Project
Partnership owns and operates a 264 unit apartment complex, located in Denton,
Texas.
 
     The Partnership was organized as a California limited partnership on July
15, 1983. The Managing General Partner of the Partnership is Angeles Properties,
Inc. ("API"). The non-managing general partners, who also serve as non-managing
general partners of the Project Partnership, are the Elliott Family Partnership,
Ltd. (a California limited partnership) and the Elliott Accommodation Trust (a
California limited partnership). The general partners act as general partners in
other limited partnerships and are affiliates of Angeles Investment Properties,
Inc. ("AIPI"), the Project Partnership's managing general partner. Pursuant to
the terms of the Agreement and Amended Certificate of Limited Partnership (the
"Agreement"), the general partners have contributed $26,000 to the Partnership
for which they are entitled to a 2% interest in the operating profits, losses,
credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $2,548,000.
Pursuant to the terms of the Agreement, the limited partners will receive a 98%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership has made capital contributions to the Project Partnership
and is entitled to a 98% interest in the operating profits, losses, credits and
cash distributions of the Project Partnership. The Project Partnership's general
partners are entitled to the remaining 2% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership tax returns. The tax basis used differs from GAAP primarily because
on the tax basis (1) certain rental income received in advance is recorded as
income in the year received rather than in the year earned, (2) buildings and
related personal property are depreciated using the lives specified under the
accelerated cost recovery system ("ACRS") or the modified accelerated cost
recovery system ("MACRS") instead of over the estimated lives of the assets, (3)
syndication costs are carried at their original value, instead of being
amortized over the estimated life of assets, and (4) subsidiary income is
recorded at the partnership level based on the partnership agreement and the
Internal Revenue Code instead of being recorded based solely on the percentage
of ownership interest.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

                        INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property.
 
  Other Assets
 
     Other assets at December 31, 1995 and 1994 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization. Also included in other assets at December 31, 1995
and 1994 are $69,622 of syndication fees which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers cash and
all highly liquid investments, with an original maturity of three months or less
when purchased, to be cash and cash equivalents.
 
  Reclassifications
 
     Certain 1994 amounts have been reclassified to conform to the 1995
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrows at December 31, 1995 and 1994 consist of the following:

     In July 1993, Angeles Mortgage Investment Trust ("AMIT"), a real estate
investment trust, initiated litigation against the Partnership and other
partnerships which loaned money to AMIT seeking to avoid repayment of such
obligations. The Partnership subsequently filed a counterclaim against AMIT
seeking to enforce the obligation, the principal amount of which is $650,000
plus accrued interest from March 1993 ("AMIT Obligation"). In 1993, the
Partnership wrote off this receivable as a bad debt.
 
     MAE GP Corporation ("MAE GP"), an affiliate of the Managing General
Partner, owns 1,675,113 Class B Shares of AMIT. MAE GP has the option to convert
these Class B Shares, in whole or in part, into Class A Shares on the basis of 1
Class A Share for every 49 Class B Shares. These Class B Shares entitle MAE GP
to receive 1.2% of the distributions of net cash distributed by AMIT. These
Class B Shares also entitle MAE GP to vote on the same basis as Class A Shares
which allows MAE GP to vote approximately 37% of the total shares (unless and
until converted to Class A Shares at which time the percentage of the vote
controlled represented by the shares held by MAE GP would approximate 1.2% of
the vote). Between the date of acquisition of these shares (November 24, 1992)
and March 31, 1995, MAE GP has declined to vote these shares. Since that date,
MAE GP voted its shares at the 1995 annual meeting in connection with the
election of trustees and other matters. MAE GP has not exerted and continues to
decline to exert any management control over or participate in the management of
AMIT. MAE GP may choose to vote these shares as it deems appropriate in the
future. In addition, Liquidity Assistance, LLC, ("LAC"), an affiliate of the
Managing General Partner and an affiliate of Insignia Financial Group, Inc.,
which provides property management and partnership administration services to
the Partnership, owns 63,200 Class A Shares of AMIT. These Class A Shares
entitle LAC to vote approximately 1.5% of the total shares.
 
     On November 9, 1994, the Partnership executed a definitive Settlement
Agreement to settle the dispute with respect to the AMIT Obligation. The actual
closing of the Settlement occurred April 14, 1995. The Partnership's claim was
satisfied by a cash payment to the Partnership totaling $544,116 (the
"Settlement Amount") at closing. Income was recorded in 1995 equal to the cash
payment and is included in other income.
 
     As part of the above described settlement, MAE GP granted to AMIT an option
to acquire the Class B shares owned by it. This option can be exercised at the
end of 10 years or when all loans made by AMIT to partnerships affiliated with
MAE GP as of November 9, 1994, which is the date of execution of the Settlement
Agreement, have been paid in full, but in no event prior to November 9, 1997.
AMIT delivered to MAE GP cash in the sum of $250,000 at closing, which occurred
April 14, 1995, as payment for the option. Upon exercise of the option, AMIT
would remit to MAE GP an additional $94,000.

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS --
                        INCOME TAX BASIS -- (CONTINUED)
 
     Simultaneously with the execution of the option agreement, MAE GP executed
an irrevocable proxy in favor of AMIT the result of which is MAE GP will be able
to vote the Class B shares on all matters except those involving transactions
between AMIT and MAE GP affiliated borrowers or the election of any MAE GP
affiliate as an officer or trustee of AMIT. On those matters, MAE GP granted to
the AMIT trustees, in their capacity as trustees of AMIT, proxies with regard to
the Class B shares instructing such trustees to vote said Class B shares in
accordance with the vote of the majority of the Class A Shares voting to be
determined without consideration of the votes of "Excess Class A Shares" as
defined in section 6.13 of the Declaration of Trust of AMIT.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2017
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2018
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Lake Eden Associates, L.P. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner (the "general partner") of
     your partnership and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2023
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2024
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $1,319.86 per unit for the six
     months ended June 30, 1998 (equivalent to $2,639.72 on an annual basis). We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $     per year
     on the number of Tax-Deferral   % Preferred OP Units, or distributions of
     $     per year on the number of Tax-Deferral Common OP Units, that you
     would receive in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
 
                                       S-4
<PAGE>   2026
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;

  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2029
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   2030
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   2031
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   2032
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   2033
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently do not own any limited partnership interest in
your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   2034
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an
opportunity to increase our investment in apartment properties, and provide you
and your partners with an opportunity to liquidate your current investment and
to invest in our operating partnership or receive cash, or to retain your units.
 
     Fractional OP Units. We will issue fractional Tax-Deferral Common OP Units
or Tax-Deferral      % Preferred OP Units, if necessary.

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

                                      S-14
<PAGE>   2036
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-average market mortgage interest rates.
In addition, we considered the recent decline in the market for equity
securities, including those of REITs and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely-accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
                                      S-16
<PAGE>   2038
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.

CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $104,498 in 1996, $111,851 in 1997 and $54,902 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Lake Eden Associates, L.P. is a Delaware
limited partnership which was formed on January 11, 1985 for the purpose of
owning and operating a single apartment property located in Columbus, Ohio,
known as "Lake Eden/Lebanon Station Apartments". In 1985, it completed a private
placement of units that raised net proceeds of approximately $2,045,000. Your
partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2008, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.

<PAGE>   2040
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $7,041,590, payable to Marine Midland and
Bank of America, which bears interest at a rate of 7.60%. The mortgage debt is
due in November 2002. Your partnership also has a second mortgage note
outstanding of $250,216, on the same terms as the current mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loans outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2048
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code.
 
     The particular tax consequences for you of our offer will depend upon a
number of factors related to your tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership (and
therefore are no longer subject to the "passive" loss rules with respect to your
partnership). Because the income tax consequences of tendering units will not be
the same for everyone, you should consult your own tax advisor with specific
reference to your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I
 
                                      S-27
<PAGE>   2049
 
Preferred Stock or the Class A Common Stock will trade following the time at
which Preferred OP Units or Common OP Units may be redeemed for shares of Class
I Preferred Stock or Class A Common Stock. Furthermore, the liquidity of the
Class I Preferred Stock and the Class A Common Stock at the time at which OP
Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $1,319.86 (equivalent to
$2,639.72 on an annualized basis). This is equivalent to distributions of $
per year on the number of Tax-Deferral   % Preferred OP Units, or distributions
of $     per year on the number of Tax-Deferral Common OP Units, that you would
receive in an exchange for each of your partnership's units. Therefore
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns
 
                                      S-28
<PAGE>   2050
 
surrounding AIMCO's ability to successfully implement its financial strategy
while maintaining a prudent capital structure as a result of the more difficult
general capital market conditions. Moody's noted that AIMCO's access to the
public markets may prove challenging in light of the volatility in both the
equity and capital markets for REITs. Moody's assigned a "ba3" rating to the
Class I Preferred Stock proposed to be issued by AIMCO, and confirmed its
previous ratings related to AIMCO's increasing leveraged profile, including high
levels of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation
 
                                      S-29
<PAGE>   2051
 
methods to estimate the fair market value of your partnership's assets. Instead,
such assets would be valued through negotiations with prospective purchasers (in
many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.

     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2054
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2055
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   2056
Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation
to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   2057
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of considerations being offered, or increasing or decreasing the
percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   2058
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   2059
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units
tendered pursuant to the offer, may postpone the purchase of, and payment for,
units tendered, and may terminate or amend the offer if at any time from or
after           , 1998 and at or before the time of acceptance for payment of
any such units (whether or not any units have theretofore been accepted for
payment and paid for) pursuant to the offer, any of the following shall occur:
 
        (a) any change (or any condition, event or development involving a
     prospective change) shall have occurred or been threatened in the business,
     properties, assets, liabilities, indebtedness, capitalization, condition
     (financial or otherwise), operations, licenses or franchises, management
     contract, or results of operations or prospects of your partnership or
     local markets in which your partnership owns or operates its property,
     including any fire, flood, natural disaster, casualty loss, or act of God
     that, in the sole judgment of the AIMCO Operating Partnership, is or may be
     materially adverse to your partnership or the value of your units to the
     AIMCO Operating Partnership, or the AIMCO Operating Partnership shall have
     become aware of any facts relating to your partnership, its indebtedness or
     its operations which, in the sole judgment of the AIMCO Operating
     Partnership, has or may have material significance with respect to the
     value of your partnership or the value of your units to the AIMCO Operating
     Partnership; or
 
          (b) there shall have occurred (i) any general suspension of trading
     in, or limitation on prices for, securities on any national securities
     exchange or the over-the-counter market in the United States, (ii) a
     decline in the closing share price of AIMCO's Class A Common Stock of more
     than 7.5% per share, from           , 1998 (iii) any extraordinary or
     material adverse change in the financial, real estate or money markets or

     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   2062
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   2064
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   2065
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   2066
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,

     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             of Class I Preferred Stock. The redemption price for

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   2072
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   2073
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-average market mortgage interest rates.
In addition, we considered the recent decline in the market for equity
securities, including those of REITs, and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   2075
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   2076
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $1,319.86 (equivalent to $2,639.72
     on an annualized basis). This is equivalent to distributions of $     per
     year on the number of Tax-Deferral   % Preferred OP Units, or distributions
     of $     per year on the number of Tax-Deferral Common OP Units, that you
     would receive in an exchange for each of your partnership's units.
     Therefore distributions with respect to the Preferred OP Units and Common
     OP Units that we are offering are expected to be        , immediately
     following our offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions." See "Comparison of Ownership of Your Units and
     AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method
 
                                      S-55
<PAGE>   2077
 
     described in "Valuation of Units" provides a meaningful indication of value
for residential apartment properties although there are other ways to value real
estate. A liquidation in the future might generate a higher price for holders of
units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

apartment properties, the manner in which your partnership's property is sold
and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

     performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
                                      S-59
<PAGE>   2081
 
     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $104,498 in 1996, $111,851 in 1997 and $54,902 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Lake Eden Associates, L.P. is a Delaware limited partnership which raised
net proceeds of approximately $2,045,000 in 1985 through a private offering. The
promoter for the private offering of your partnership was Jacques-Miller.
Insignia acquired your partnership in December 1991. AIMCO acquired Insignia in
October, 1998. There are currently a total of 64 limited partners of your
partnership and a total of 35.3 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on January 11, 1985 for the purpose of owning
and operating a single apartment property located in Columbus, Ohio, known as
"Lake Eden/Lebanon Station Apartments." Your partnership's property consists of
387 apartment units. There are 184 one-bedroom apartments, 173 two-bedroom
apartments and 30 three-bedroom apartments. The total rentable square footage of
your partnership's property is 293,708 square feet. Your partnership's property
had an average occupancy rate of approximately 96.90% in 1996 and 96.90% in
1997. The average annual rent per apartment unit is approximately $5,432.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $104,498, $111,851 and $54,902, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2008
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $7,041,590, payable to Marine Midland and Bank of America, which
bears interest at a rate of 7.60%. The mortgage debt is due in November 2002.
Your partnership also has a second mortgage note outstanding of $250,216, on the
same terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows the general partner of your partnership to lend funds to
your partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.

     Your partnership recognized net income of $117,218 for the six months ended
June 30, 1998, compared to $76,594 for the six months ended June 30, 1997. The
increase in net income of $40,624, or 53.04% was primarily the result of a
decrease in operating expenses partially offset by a slight decrease in total
revenues. These factors are discussed in more detail in the following
paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,090,117 for the six months ended June 30, 1998, compared to $1,105,569 for
the six months ended June 30, 1997, a decrease of $15,452, or 1.40%.
 
     Expenses
 
     Operating expenses, consisting of, utilities net of reimbursements received
from tenants, contract services, turnover costs, repairs and maintenance,
advertising and marketing, and insurance, totaled $467,873 for the six months
ended June 30, 1998, compared to $525,909 for the six months ended June 30,
1997, a decrease of $58,036 or 11.04%. This decrease was primarily due to a
decrease in exterior painting and other non-capitalizable property improvement
expenses. Management expenses totaled $54,902 for the six months ended June 30,
1998, compared to $55,956 for the six months ended June 30, 1997, a decrease of
$1,054, or 1.88%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $43,187 for the six months
ended June 30, 1998 compared to $32,754 for the six months ended June 30, 1997,
an increase of $10,433 or 31.85%. The increase is primarily due to increases in
asset management fees and general partner reimbursements.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $279,607 for the six months ended June 30, 1998, compared to
$287,853 for the six months ended June 30, 1997, a decrease of $8,246, or 2.86%.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized net income of $252,740 for the year ended
December 31, 1997, compared to $48,490 for the year ended December 31, 1996. The
increase in net income of $204,250, or 421.22% was primarily the result of an
increase in rental revenue and other income and a decrease in operating
expenses. These factors are discussed in more detail in the following
paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$2,249,681 for the year ended December 31, 1997, compared to $2,115,254 for the
year ended December 31, 1996, an increase of $134,427, or 6.36%. This increase
was primarily the result of an increase in occupancy.

Management expenses totaled $111,851 for the year ended December 31, 1997
compared to $104,498 for the year ended December 31, 1996. The increase of

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $116,610 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership are
not liable to your partnership or any limited partner for any acts performed by
any of them or any failure to act in the absence of gross negligence or willful
malfeasance. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest."
 
     Your partnership's agreement of limited partnership does not provide for
the indemnification of the general partners or their affiliates for any acts or
omissions performed by them on behalf of your partnership.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter.

1998 (through June 30)......................................     1,319.86
</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Lake Eden, Limited as of
June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Lake Eden, Limited:
 
     We have audited the accompanying balance sheets of Lake Eden, Limited as of
December 31, 1997 and 1996, and the related statements of operations and changes
in partners' deficit and cash flows for the years then ended. These financial
statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Lake Eden, Limited as of
December 31, 1997 and 1996, and the results of its operations and its cash flows
for the years then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Lake Eden, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated January 11,
1985. The Partnership owns and operates a 387 unit apartment residential
complex, Lake Eden/Lebanon Station Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include unamortized deferred
loan costs of $116,535 and $140,231, respectively, which are amortized over the
term of the related borrowing. They are presented net of accumulated
amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the
following:

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Lake Eden, Limited:
 
     We have audited the accompanying balance sheets of Lake Eden, Limited as of
December 31, 1996 and 1995, and the related statements of operations and changes
in partners' deficit and cash flows for the years then ended. These financial
statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Lake Eden, Limited as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for the years then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Lake Eden, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated January 11,
1985. The Partnership owns and operates a 387 unit apartment residential
complex, Lake Eden/ Lebanon Station Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Management Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 consist of deferred loan costs
which are amortized over the term of the related borrowing. They are presented
net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
                                       A-1
<PAGE>   2123
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2124
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

A:   We are offering to acquire your units of limited partnership interest in

     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million , total debt of $1,626 million and
     stockholders' equity of $1,844 million .
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.

<PAGE>   2129
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2130
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $246.13 per unit for the six months
     ended June 30, 1998 (equivalent to $492.26 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the quarter ended June 30, 1998, we paid distributions of
     $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25 on
     an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral   % Preferred OP Units or distributions
     of $          per year on the number of Tax-Deferral Common OP Units that
     you would receive in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if more than 50% or
     more of the total interests in your partnership are transferred within a
     12-month period. If we acquire a significant percentage of the interest in
     your partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration of $          in cash per
     unit is fair. However, your units are not listed on any national securities
     exchange nor quoted on the NASDAQ System, and there is no established
     trading market for your units. Secondary sales activity for the units has
     been limited and sporadic. Your general partner does not monitor or
     regularly receive or maintain information regarding the prices at which
     secondary sale transactions in the units have been effectuated.
 
                                       S-4
<PAGE>   2132
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.

Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit date compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
                                       S-7
<PAGE>   2135
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   2136
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   2137
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   2138
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   2139
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently do not own any limited partnership interest in
your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the
 
                                      S-12
<PAGE>   2140
 
     continued operation of your partnership. Given improving rental market
     conditions, the level of distributions might increase over time. We believe
     it is possible that the private resale market for apartment and retail
     properties could improve over time, making a sale of your partnership's
     property in a private transaction at some point in the future a more viable
     option than it is currently. However, there are several risks and
     disadvantages that result from continuing the operations of your
     partnership without the offer. Your partnership faces maturity or balloon
     payment dates on its mortgage loans and must either obtain refinancing or
     sell its property. If your partnership were to continue operating as
     presently structured, it could be forced to borrow on terms that could
     result in net losses from operations. In addition, continuation of your
     partnership without the offer would deny you and your partners the benefits
     that your general partner expects to result from the offer. For example, a
     partner of your partnership would have no opportunity for liquidity unless
     he were to sell his units in a private transaction. Any such sale would
     likely be at a very substantial discount from the partner's pro rata share
     of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future
 
                                      S-13
<PAGE>   2141
 
      increase in the AIMCO stock price and from any future increase in
      distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."

     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an
opportunity to increase our investment in apartment properties, and provide you
and your partners with an opportunity to liquidate your current investment and
to invest in our operating partnership or receive cash, or to retain your units.
 
     Fractional OP Units. We will issue fractional Tax-Deferral Common OP Units
or Tax-Deferral      % Preferred OP Units, if necessary.
 
     Delivery of OP Units and Cash. We will deliver OP Units and cash as soon as
practicable after acceptance of units for purchase.

Information Agent in connection with the offer (the "Information Agent"). Its
telephone number is (888) 349-2005 or (201) 896-1900.
 
     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common
 
                                      S-15
<PAGE>   2143
 
     OP Units. You will recognize a gain or loss for Federal income tax purposes
on units you sell for cash. The exchange of your units for cash and OP Units
will be treated, for Federal income tax purposes, as a partial sale of such
units for cash and as a partial tax-free contribution of such units to our
operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" OF THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $35,967 in 1996, $35,122 in 1997 and $16,115 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Landmark Associates, Ltd. is a Tennessee
limited partnership which was formed on July 30, 1982 for the purpose of owning
and operating a single apartment property located in
                                      S-18
<PAGE>   2146
 
Florence, South Carolina, known as "Landmark Woods Apartments." In 1982, it
completed a private placement of units that raised net proceeds of approximately
$1,132,000. Landmark Woods Apartments consists of 104 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2025, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,448,213, payable to State Street and
Lehman, which bears interest at a rate of 7.29%. The mortgage debt is due in
January 2028. Your partnership's agreement of limited partnership also allows
your general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were

     the completion of the business combination with AIMCO Properties, L.P.

     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated

(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2154
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-27
<PAGE>   2155
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $       , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June, 1998 were $246.13 per unit (equivalent to
$492.26 on an annualized basis). This is equivalent to distributions of $
per year on the number of Tax-Deferral   % Preferred OP Units, or distributions
of $     per year on the number of Tax-Deferral Common OP Units, that you would
receive in an exchange for each of your partnership's units. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership
 
                                      S-28
<PAGE>   2156
 
were to be reduced, and you do not tender all of your units pursuant to our
offer, you will be treated as receiving a hypothetical distribution of cash
resulting from a decrease in your share of the liabilities of your partnership.
Any such hypothetical distribution of cash would be treated as a nontaxable
return of capital to the extent of your adjusted tax basis in your units and
thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
                                      S-29
<PAGE>   2157
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to
 
                                      S-30
<PAGE>   2158
 
continue operating as presently structured, your partnership could be forced to
borrow on terms that could result in net losses from operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax Deferral      % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2160
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2161
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   2162
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   2163
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of considerations being offered, or increasing or decreasing the
percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
                                      S-36
<PAGE>   2164
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   2165
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units
tendered pursuant to the offer, may postpone the purchase of, and payment for,

        (f) a tender or exchange offer for any units shall have been commenced

circumstances and each right shall be deemed a continuing right which may be

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   2168
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   2170
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   2171
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             shares held in the trust. Any proceeds in excess of the
                                                             amount payable to the prohibited transferee will be
                                                             payable to the charitable beneficiaries.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   2178
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   2179
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-average market mortgage interest rates.
In addition, we considered the recent decline in the market for equity
securities, including those of REITs, and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   2182
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-55
<PAGE>   2183
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions of $2.25 with respect
     to the Common OP Units and distributions with respect to your units for the
     six months ended June, 1998 were $246.13 (equivalent to $492.26 on an
     annualized basis). This is equivalent to distributions of $     per year on
     the number of Tax-Deferral      % Preferred OP Units, or distributions of
     $     per year on the number of Tax-Deferral Common OP Units, that you
     would receive in exchange for each of your partnership's units. Therefore,
     distributions with respect to the Preferred OP Units and Common OP Units
     being offered are expected to be      , immediately following the offer,
     than the distributions with respect to your units. See "Comparison of
     Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-56
<PAGE>   2184
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-60
<PAGE>   2188
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner but may receive reimbursement for expenses
generated in that capacity. The property manager received management fees of
35,967 in 1996, $35,112 in 1997 and 16,115 for the first six months of 1998. The
AIMCO Operating Partnership has no current intention of changing the fee
structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Landmark Associates, Ltd. is a Tennessee limited partnership which raised
net proceeds of approximately $1,132,000 in 1982 through a private offering. The
promoter for the private offering of your partnership was Jacques-Miller.
Insignia acquired your partnership in December 1991. AIMCO acquired Insignia in
October, 1998. There are currently a total of 35 limited partners of your
partnership and a total of 1,132 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on July 30, 1982 for the purpose of owning and
operating a single apartment property located in Florence, South Carolina, known
as "Landmark Woods Apartments." Your partnership's property consists of 104
apartment units. There are 24 one-bedroom apartments, 56 two-bedroom apartments
and 29 three-bedroom apartments. The total rentable square footage of your
partnership's property is 100,472 square feet. The average annual rent per
apartment unit is approximately $5,878.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $35,967, $35,112 and $16,115, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2025
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $2,448,273, payable to State Street and Lehman, which bears
interest at a rate of 7.29%. The mortgage debt is due in January 2028. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not

$314,774 for the six months ended June 30, 1998, compared to $374,345 for the
six months ended June 30, 1997, a decrease of $59,571, or 15.91%. This was
primarily a result of an increase in vacancy and concession losses in 1998.

calculated based on a percentage of revenue.

ended June 30, 1998 compared to $18,153 for the six months ended June 30, 1997,

costs, totaled $91,007 for the six months ended June 30, 1998, compared to

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership are
not liable to your partnership or any limited partner for any acts performed by
any of them or any failure to act in the absence of gross negligence or willful
malfeasance. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest."
 
     Your partnership's agreement of limited partnership does not provide for
the indemnification of the general partners or their affiliates for any acts or
omissions performed by them on behalf of your partnership. As part of its
assumption of liabilities in the consolidation, AIMCO will indemnify the general
partner of your partnership and their affiliates for periods prior to and
following the consolidation to the extent of the indemnity under the terms of
your partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Landmark Associates,
Limited as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with generally accepted accounting principles
for interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

General Partners
Landmark Associates, Limited:
 
     We have audited the accompanying balance sheets of Landmark Associates,
Limited as of December 31, 1997 and 1996, and the related statements of
operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Landmark Associates, Limited
as of December 31, 1997 and 1996, and the results of its operations and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles.

                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Landmark Associates, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated July 30,
1982. The Partnership owns and operates a 104 unit apartment complex, Landmark
Woods Apartments, in Florence, South Carolina.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$71,389 and $18,855, respectively, which are amortized over the term of the
related borrowing. They are shown net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the
following:

NOTE C -- MORTGAGE NOTE PAYABLE
 
     In November 1997, the Partnership refinanced its first mortgage note with
an outstanding balance of $2,104,201. The new mortgage note in the amount of
$2,500,000 is payable in monthly installments of $17,122, at 7.29% with the
remaining balance due December 2004; collateralized by land and buildings. A
loss on refinancing of $8,954 was realized 1997, as a result of the write-off of
unamortized loan costs associated with the original note. Loan costs of $71,389
related to the refinanced note were capitalized.
 
     Between the date of November 1, 2000 and June 1, 2004, upon giving 30 days
prior written notice, the principal balance may be prepaid in whole but not in
part by paying a prepayment premium in an amount equal to the greater of (1) 1%
of the principal amount being prepaid or (2) the present value of a series of
payments each equal to the payment differential (the interest rate (7.29%) less
the reinvestment yield (the lesser of the yield on the U.S. Treasury issue with
a maturity date closest to the maturity date or the yield on the U.S. Treasury
issue with a term equal to the remaining average life of the debt with each
yield being based on the bid price for such issue as published in the Wall
Street Journal on the date that is 14 days prior to the prepayment date divided
by 12 and multiplied by the principal sum outstanding on the prepayment date))
and payable on each monthly payment date over the remaining original term of
this note and the maturity date discounted at the reinvestment yield for the
number of months remaining from the prepayment date to each such monthly payment
date and the maturity date.
 
     Scheduled principal payments of the mortgage note during the years
subsequent to December 31, 1997 are as follows:

General Partners
Landmark Associates, Limited:
 
     We have audited the accompanying balance sheets of Landmark Associates,
Limited as of December 31, 1996 and 1995, and the related statements of
operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Landmark Associates, Limited
as of December 31, 1996 and 1995, and the results of its operations and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles.

                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Landmark Associates, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated July 30,
1982. The Partnership owns and operates a 104 unit apartment complex, Landmark
Woods Apartments, in Florence, South Carolina.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net income or partners'

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2228
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2229
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Minneapolis Associates II Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partnership") and the company that manages the property owned by
     your partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2234
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2235
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0 per unit for the six months ended
     June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY

                                       S-3
<PAGE>   2236
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if 50% or more of the
     total interests in your partnership are transferred within a 12-month
     period. If we acquire a significant percentage of the interest in your
     partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership. In addition, if there is a sale or exchange of 50% or more of
     the total interest in capital and profits of your partnership within any
     12-month period, including sales or exchanges resulting from the offer,
     your partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to
 
                                       S-4
<PAGE>   2237
 
     your partnership's annual net operating income. We determined an
     appropriate capitalization rate using our best judgment, but our valuation
     is just an estimate. Although the direct capitalization method is a
     widely-accepted way of valuing real estate, there are a number of other
     methods available to value real estate, each of which may result in
     different valuations of the property. The proceeds that you would receive
     if you sold your units to someone else or if your partnership were actually
     liquidated might be higher or lower than our offer consideration. An actual
     liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the
 
                                       S-5
<PAGE>   2238
 
     expiration of the offer, and you must follow the instructions provided with
     the Letter of Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2240
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   2241
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   2242
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   2243
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   2244
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
 
                                      S-12
<PAGE>   2245
 
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have
 
                                      S-13
<PAGE>   2246
 
      the opportunity to participate in the growth of our enterprise and would
      benefit from any future increase in the AIMCO stock price and from any
      future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %
Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any combination
of such forms of consideration for your units. The offer is made upon the terms
and subject to the conditions set forth in this Prospectus Supplement, the
accompanying Prospectus and the accompanying Letter of Transmittal, including
the instructions thereto, as the same may be supplemented or amended from time
to time (the "Letter of Transmittal"). To be eligible to receive Tax-Deferral
     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an

     Delivery of OP Units and Cash. We will deliver OP Units and cash as soon as

Information Agent in connection with the offer (the "Information Agent"). Its

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the
 
                                      S-17
<PAGE>   2250
 
fairness opinion. Based on its analysis, and subject to the assumptions,
limitations and qualifications cited in its opinion, Stanger concluded that our
offer consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the aggregate capital
contributions that can be made by limited partners which is not the case with
the AIMCO Operating Partnership.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
in its capacity as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $155,150 in 1996, $160,843 in 1997 and $90,029 for
the first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. Minneapolis Associates II Limited
Partnership is a Massachusetts limited partnership which was formed on May 12,
1983 for the purpose of owning and operating, through a 45% interest in
Burnsville Apartment Limited Partnership, a single apartment property located in
Burnsville, Minnesota, known as "The Woods of Burnsville." In 1989, it completed
a private placement of units. The Woods at Burnsville consists of 400 apartment
units. Your partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2033, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of December 31, 1997, your partnership
had a first mortgage in the amount of $16,580,000, a second mortgage in the
amount of $550,000, and a third mortgage in the amount of $750,000, all due
August 1999, payable to Dreyfus. The first mortgage bears interest at 7.00%, and
the second and third mortgages do not bear interest. Your partnership's
agreement of limited partnership also allows your general partner to lend to
your partnership. The property also secures $275,892 owed to the general partner
due in August 1999.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $          will be required to purchase all of
the units sought in our offer, if such units are tendered for cash. We will
obtain all such funds from cash from operations, equity issuances and short term
borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2259
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-27
<PAGE>   2260
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of $0
with respect to your units, distributions with respect to the Preferred OP Units
and Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your
 
                                      S-28
<PAGE>   2261
 
partnership. Any such hypothetical distribution of cash would be treated as a
nontaxable return of capital to the extent of your adjusted tax basis in your
units and thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
                                      S-29
<PAGE>   2262
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to
 
                                      S-30
<PAGE>   2263
 
continue operating as presently structured, your partnership could be forced to
borrow on terms that could result in net losses from operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units. Your Partnership has
       not paid any distributions on your units since the inception of your
       partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
                                      S-31
<PAGE>   2264
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   2266
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   2267
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-35
<PAGE>   2268
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-36
<PAGE>   2269
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   2270
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.

     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

<PAGE>   2273
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced
     or publicly proposed to be made by another person or "group" (as defined in
     Section 13(d)(3) of the Securities Exchange Act of 1934), or it shall have

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-41
<PAGE>   2274
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $          .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-43
<PAGE>   2276
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-44
<PAGE>   2277
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   2284
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   2285
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including

     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-56
<PAGE>   2289
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1998 distributions of $     with
     respect to your units, distributions with respect to the Preferred OP Units
     and Common OP Units being offered are expected to be      , immediately
     following the offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-57
<PAGE>   2290
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-61
<PAGE>   2294
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
in its capacity as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $155,150 in 1996, $160,843 in 1997 and $90,029 for
the first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Minneapolis Associates II Limited Partnership is a Massachusetts limited
partnership which owns a 45% interest in Burnsville Apartment Limited
Partnership. Insignia acquired your partnership in November 1997. AIMCO acquired
Insignia in October, 1998. There are currently a total of 35 limited partners of
your partnership and a total of 79 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 12, 1983 for the purpose of owning and
operating, through Burnsville Apartment Limited Partnership, a single apartment
property located in Burnsville, Minnesota, known as "The Woods of Burnsville."
Your partnership's property consists of 400 apartment units. The total rentable
square footage of your partnership's property is 359,861 square feet. The
average annual rent per apartment unit is approximately $8,049.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $155,150, $160,843 and $90,029, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2033
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement
                                      S-73
<PAGE>   2306
 
     of various building systems and other replacements and renovations in the
ordinary course of business. All capital improvement and renovation costs are
expected to be paid from operating cash flows, cash reserves, or from short-term
or long-term borrowings. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of December 31, 1997, your partnership had a first mortgage in
the amount of $16,580,000, a second mortgage in the amount of $550,000, and a
third mortgage in the amount of $750,000, all due August 1999, payable to
Dreyfus. The first mortgage bears interest at 7.00%, and the second and third
mortgages do not bear interest. Your partnership's agreement of limited
partnership also allows your general partner to lend to your partnership. The
property also secures $275,892 owed to the general partner due in August 1999.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable to your partnership or any limited partner for any
loss suffered by your partnership which arises out of any action or inaction of
the general partner or its affiliates if the general partner or its affiliates,
in good faith, determined that such course of conduct was in the best interests
of your partnership and such course of conduct did not constitute negligence or
misconduct on the part of the general partner or its affiliates. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss, judgments, liabilities, expenses and amounts
paid in settlement of any claims sustained by them in connection with your
partnership, provided that the same were not the result of negligence or
misconduct on the part of the general partner or its affiliates. Any indemnity
paid will be paid from, and only to the extent of, your partnership's assets and
no partner will have any personal liability on account thereof. As part of its
assumption of liabilities in the consolidation, AIMCO will indemnify the general
partner of your partnership and their affiliates for periods prior to and
following the consolidation to the extent of the indemnity under the terms of
your partnership's agreement of limited partnership and applicable law.
 
     Your partnership will not incur the cost of the portion of any insurance
which insures any party against any liabilities as to which such party is
prohibited from being indemnified under your partnership's agreement of limited
partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has made no distributions in the past five years.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership has not received any compensation
from your partnership.
 
     An affiliate of AIMCO manages the property of your partnership. Your
partnership has historically paid the property management fees as described in
the following table:
 
<TABLE>
<CAPTION>

1997...........................................      160,843
1998 (through June 30).........................       90,029
</TABLE>
 
     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.
 
     Below is an itemized statement of the estimated expenses incurred and to be
incurred in the offer by AIMCO:

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Burnsville Apartments
Limited Partnership as of June 30, 1998 and for the six months ended June 30,
1998 have been prepared in accordance with generally accepted accounting
principles for interim financial information. Accordingly, they do not include
all the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments considered necessary for a fair presentation have been included and
all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
Burnsville Apartments Limited Partnership
 
     We have audited the accompanying balance sheets of Burnsville Apartments
Limited Partnership as of December 31, 1997 and 1996, and the related statements
of operations, partners' deficit and cash flows for the years then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Burnsville Apartments
Limited Partnership as of December 31, 1997 and 1996, and the results of its
operations, the changes in partners' deficit and cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Burnsville Apartments Limited Partnership ("the Partnership") was formed as
a limited partnership under the laws of the State of Minnesota on May 12, 1983,
for the purpose of developing, constructing and operating a multi-family housing
project. The project consists of 400 units and is operating under the name of
The Woods of Burnsville. The Partnership has entered into an agreement with the
City of Burnsville which provides for the rental of at least 20% of the units to
tenants whose income does not exceed 80% of the median area income. This
restriction is necessary in order for the Partnership to comply with the
provisions of the Internal Revenue Code governing preservation of the tax-exempt
status of the bonds issued by the City of Burnsville.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. Depreciation is provided for
in amounts sufficient to relate the cost of depreciable assets to operations
over their estimated service lives on the straight-line method. For income tax
purposes, accelerated methods and lives are used.
 
  Amortization
 
     Financing fees are being amortized over the term of the mortgage loan using
the straight-line method.
 
  Income Taxes
 
     No provision or benefit for income taxes has been included in these
financial statements since taxable income or loss passes through to, and is
reportable by, the partners individually.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the Partnership and
tenants of the property are operating leases.
 
  Cash Equivalents
 
     For purposes of the statements of cash flows, the Partnership considers all
highly liquid investments to be cash equivalents.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
NOTE B -- FINANCING
 
     A first mortgage in the amount of $16,580,000 is due August 1, 1999, with
semi-annual payments of interest only at 7% per annum until maturity ($580,300
is being held in a bond reserve fund by the trustee to fund interest payments on
the bonds, if necessary). The City of Burnsville, Minnesota, has issued a 1989
series of tax-exempt bonds, which are secured by an irrevocable letter-of-credit
for $17,218,330 ($16,580,000 to pay principal on the bonds and $638,330 to pay
interest on the bonds or the portion of the bonds representing accrued
interest). The Partnership is obligated to reimburse the lender for any amount
drawn on the letter-of-

credit. There was no outstanding balance at December 31, 1997. The mortgage is
secured by the rental property and an assignment of all project rents and
leases.
 
     The Partnership has established an interest reserve account to pay the
semi-annual interest payments due February and August of each year. At December
31, 1997 and 1996, the interest reserve balance is $716,005 and $634,141,
respectively.
 
     A second mortgage in the amount of $550,000 is noninterest bearing and is
due August 1, 1999. This note is secured by the rental property and an
assignment of all project rents and leases and is subordinate to the first
mortgage.
 
     The remaining debt is evidenced by a third mortgage in the amount of
$750,000, which is noninterest bearing and is due August 1, 1999. This note
requires the payment of bonus interest up to $250,000 based on the net proceeds
received in the event of a sale or refinancing of the property. Such interest
will be expensed, if applicable, upon a sale or refinancing. This note is also
secured by the rental property and an assignment of all project rents and leases
and is subordinate to the first and second mortgages.
 
     Bond fees of $36,516 and $49,970 related to the administration of the bonds
were charged to operations during 1997 and 1996, respectively.
 
NOTE C -- RELATED PARTY TRANSACTION
 
     The project was managed through October 27, 1997 by Winthrop Management, an
affiliate of the general partner, which receives an annual fee of 5% of the
gross receipts of the property. Property management fees of $132,487 and
$155,150 were charged to operations during 1997 and 1996, respectively.
 
     On October 28, 1997, the Partnership terminated Winthrop Management as the
managing agent, and appointed Insignia Residential Group, L.P. ("Insignia") the
new management agent. (See note F). The management agreement provides for a
management fee of 5% of gross receipts of the property. Property management fees
of $28,356 were charged to operations during 1997. At December 31, 1997, unpaid
management fees totaled $14,178.
 
NOTE D -- COMMITMENT
 
     The Partnership is required to provide additional capital up to $750,000 to
fund future debt service shortfalls. Minneapolis II, the general partner, agreed
to fund up to $750,000 to the Partnership for these payments. Advances from
Minneapolis II totaling $275,892 were outstanding as of December 31, 1997 and
1996, respectively.
 
     This loan is noninterest bearing and due on August 1, 1999. This loan is
equal in priority to the second mortgage and is collateralized by the rental
property.
 
NOTE E -- CONCENTRATION OF CREDIT NOTE
 
     The Partnership maintains its cash balances in three banks. The balances
are insured by the Federal Deposit Insurance Corporation up to $100,000 by each
bank. As of December 31, 1997, the uninsured portion of the cash balances held
at one of the banks was $276,155.
 
NOTE F -- OTHER INFORMATION
 
     On October 28, 1997, Insignia Financial Group ("IFG") acquired 100% of the
class B stock of First Winthrop Corporation ("FWC"). FWC is an affiliate of the
general partner.

To the Partners
Burnsville Apartments Limited Partnership
 
     We have audited the accompanying balance sheets of Burnsville Apartments
Limited Partnership as of December 31, 1996 and 1995, and the related statements
of operations, partners' deficit and cash flows for the years then ended. These
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Burnsville Apartments
Limited Partnership as of December 31, 1996 and 1995, and the results of its
operations, the changes in partners' deficit and cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                   BURNSVILLE APARTMENTS LIMITED PARTNERSHIP
 
                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Burnsville Apartments Limited Partnership ("the partnership") was formed as
a limited partnership under the laws of the State of Minnesota on May 12, 1983,
for the purpose of developing, constructing and operating a multifamily housing
project. The project consists of 400 units and is operating under the name of
The Woods of Burnsville. The partnership has entered into an agreement with the
City of Burnsville which provides for the rental of at least 20% of the units to
tenants whose income does not exceed 80% of the median area income. This
restriction is necessary in order for the partnership to comply with the
provisions of the Internal Revenue Code governing preservation of the tax exempt
status of the bonds issued by the City of Burnsville.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. Depreciation is provided for
in amounts sufficient to relate the cost of depreciable assets to operations
over their estimated service lives on the straight-line method. For income tax
purposes, accelerated methods and lives are used.
 
  Amortization
 
     Financing fees are being amortized over the term of the mortgage loan using
the straight-line method.
 
  Income Taxes
 
     No provision or benefit for income taxes has been included in these
financial statements since taxable income or loss passes through to, and is
reportable by, the partners individually.
 
  Rental Income
 
     Rental income is recognized as rentals become due. Rental payments received
in advance are deferred until earned. All leases between the partnership and
tenants of the property are operating leases.
 
  Cash Equivalents
 
     For purposes of the statements of cash flows, the partnership considers all
highly liquid investments to be cash equivalents. The carrying amount of
$132,125 approximates fair value because of the short maturity of this
instrument.
 
NOTE B -- FINANCING
 
     A first mortgage in the amount of $16,580,000 is due August 1, 1999, with
semiannual payments of interest only at 7% per annum until maturity ($580,300 is
being held in a bond reserve fund by the trustee to fund interest payments on
the bonds, if necessary). The City of Burnsville, Minnesota, has issued a 1989
series of tax-exempt bonds, which are secured by an irrevocable letter-of-credit
for $17,218,330 ($16,580,000 to pay principal on the bonds and $638,330 to pay
interest on the bonds or the portion of the bonds representing

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
accrued interest). The partnership is obligated to reimburse the Lender for any
amount drawn on the letter-of-credit. There was no outstanding balance at
December 31, 1996. The mortgage is secured by the rental property and an
assignment of all project rents and leases.
 
     The partnership has established an interest reserve account to pay the
semiannual interest payments due February and August of each year. At December
31, 1996, the interest reserve balance is $634,141.
 
     A second mortgage in the amount of $550,000 is noninterest bearing and is
due August 1, 1999. This note is secured by the rental property and an
assignment of all project rents and leases and is subordinate to the first
mortgage.
 
     The remaining debt is evidenced by a third mortgage in the amount of
$750,000, which is noninterest bearing and is due August 1, 1999. This note
requires the payment of bonus interest up to $250,000 based on the net proceeds
received in the event of a sale or refinancing of the property. Such interest
will be expensed, if applicable, upon a sale or refinancing. This note is also
secured by the rental property and an assignment of all project rents and leases
and is subordinate to the first and second mortgages.
 
     Bond fees of $49,970 and $50,294 related to the administration of the bonds
were charged to operations during 1996 and 1995, respectively.
 
NOTE C -- RELATED PARTY TRANSACTION
 
     The project is currently managed by Winthrop Management, an affiliate of
the general partner, which receives an annual fee of 5% of the gross receipts of
the property. Property management fees of $155,150 and $148,243 were charged to
operations during 1996 and 1995, respectively.
 
NOTE D -- COMMITMENT
 
     The partnership is required to provide additional capital up to $750,000 to
fund future debt service shortfalls. Minneapolis II, the general partner, agreed
to fund up to $750,000 to the partnership for these payments. Advances from
Minneapolis II totaling $275,892 were outstanding as of December 31, 1996 and
1995, respectively.
 
     This loan is noninterest bearing and due on August 1, 1999. This loan is
equal in priority to the second mortgage and is collateralized by the rental
property.

                                  APPENDIX A-1
                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2336
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2337
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Northbrook Apartments, Ltd. For each unit that you tender, you may choose
     to receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2342
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2343
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,991.94 per unit for the six
     months ended June 30, 1998 (equivalent to $4,983.88 on an annual basis). We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $0.5625 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if more than 50% or
     more of the total interests in your partnership are transferred within a
     12-month period. If we acquire a significant percentage of the interest in
     your partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership. In addition, there is a sale or exchange of 50% or more of the
     total interest in capital and profits of your partnership within any
     12-month period, including sales or exchanges resulting from the offer,
     your partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your
 
                                       S-4
<PAGE>   2345
 
     partnership using the direct capitalization method. This method involves
     applying a capitalization rate to your partnership's annual net operating
     income. We determined an appropriate capitalization rate using our best
     judgment, but our valuation is just an estimate. Although the direct
     capitalization method is a widely-accepted way of valuing real estate,
     there are a number of other methods available to value real estate, each of
     which may result in different valuations of the property. The proceeds that
     you would receive if you sold your units to someone else or if your
     partnership were actually liquidated might be higher or lower than our
     offer consideration. An actual liquidation may also result in your paying
     taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
                                       S-5
<PAGE>   2346
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2348
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code.
 
     The particular tax consequences to you of the exchange will depend upon a
number of factors related to your individual tax situation, including your tax
basis in your units, whether you dispose of all of your units in your
partnership, and whether the "passive loss" rules apply to your investments.
Because the income tax consequences of an exchange of units will not be the same
for everyone, you should consult your tax advisor before determining whether to
tender your units pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   2349
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   2350
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   2351
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   2352
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of
     Northbrook Partners, Ltd., the original limited partner. In the absence of
     such consent, your only option for liquidation of your investment would be
     to sell your units in a private transaction. Any such sale could be at a
     very substantial discount from your pro rata share of the fair market value
     of your partnership's property and might involve significant expense and
     delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
 
                                      S-12
<PAGE>   2353
 
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future
 
                                      S-13
<PAGE>   2354
 
      increase in the AIMCO stock price and from any future increase in
      distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;

     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its

expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary

financial point of view. The full text of the opinion, which contains a

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership, but may receive
reimbursement for expenses generated in that capacity from your partnership. The
property manager which received management fees of $42,282 in 1996, $42,038 in
1997 and $21,669 for the first six months of 1998. We have no current intention
of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.

     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Northbrook Apartments, Ltd. is a
Mississippi limited partnership which was formed on September 28, 1979 for the
purpose of owning and operating a single apartment property located in
Ridgeland, Mississippi, known as "Pinebrook Apartments." In 1979, it completed a
private placement of units that raised net proceeds of approximately $1,600,000.
Pinebrook Apartments consist of 160 apartment units. Your partnership has no
employees.
 
     Property Management. Since November 1992, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,460,180, payable to FNMA and GMAC,
which bears interest at a rate of 7.83%. The mortgage debt is due in October
2003. Your partnership also has a second mortgage note outstanding of $80,325,
on the same terms as the current mortgage note. Your partnership's agreement of
limited partnership also allows your general partner to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.

     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code.
 
     The particular tax consequences for you of our offer will depend upon a
number of factors related to your tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership (and
therefore are no longer subject to the "passive" loss rules with respect to your
partnership). Because the income tax consequences of tendering units will not be
the same for everyone, you should consult your own tax advisor with specific
reference to your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single
 
                                      S-27
<PAGE>   2368
 
apartment property. In contrast, the AIMCO Operating Partnership is in the
business of acquiring, marketing, managing and operating a large portfolio of
apartment properties. While diversification of assets may reduce certain risks
of investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions for the six months
ended June 30, 1998 were $3,991.94 per unit (equivalent to $4,983.88 on an
annual basis). This is equivalent to distributions of $          per year on the
number of Tax-Deferral      % Preferred OP Units, or distributions of
$          per year on the number of Tax-Deferral Common OP Units, that you
would receive in an exchange for each of your partnership's units. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations
 
                                      S-28
<PAGE>   2369
 
may cause your general partner to reduce the liabilities of your partnership. If
the liabilities of your partnership were to be reduced, and you do not tender
all of your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.

                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of Northbrook
Partners, Ltd., the original limited partner. In the absence of such consent,
your only option for liquidation would be to sell your units in a private
transaction. Any such sale
 
                                      S-30
<PAGE>   2371
 
likely would be at a very substantial discount from your pro rata share of the
fair market value of your partnership's property and might involve significant
expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
                                      S-31
<PAGE>   2372
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   2374
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the

alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.

     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY

  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-35
<PAGE>   2376
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-36
<PAGE>   2377
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-37
<PAGE>   2378
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

Partnership shall not be required to accept for payment and pay for any units

     time of the commencement of the offer, in the sole judgment of the AIMCO

Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-41

     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS

AIMCO Operating Partnership.
 
                                      S-42
<PAGE>   2383
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-43
<PAGE>   2384
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-44
<PAGE>   2385
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   2386
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46
<PAGE>   2387
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   2392
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   2393
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value, the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-55
<PAGE>   2396
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
          12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions for the six months ended June
     30, 1998 were $3,991.94 (equivalent to $4,983.88 on an annual basis). This
     is
 
                                      S-57
<PAGE>   2398
 
     equivalent to distributions of $          per year on the number of
     Tax-Deferral      % Preferred OP Units, or distributions of $          per
     year on the number of Tax-Deferral Common OP Units, that you would receive
     in exchange for each of your partnership's units. Therefore, distributions
     with respect to the Preferred OP Units and Common OP Units that we are
     offering are expected to be        , immediately following our offer, than
     the distributions with respect to your units. See "Comparison of Ownership
     of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment properties although there are
other ways to value real estate. A liquidation in the future might generate a
higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
                                      S-58
<PAGE>   2399
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."

                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.

CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.

analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer consideration for you, even as a subsidiary of AIMCO. It also has a
duty to remove the property manager for your partnership's property, under
certain circumstances, even though the property manager is also an affiliate of
AIMCO. The conflicts of interest include the fact that a decision to remove, for
any reason, the general partner of your partnership from its current position as
a general partner of your partnership would result in a decrease or elimination
of the substantial management fees paid to an affiliate of the general partner
of your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager which
received management fees of $42,282 in 1996, $42,038 in 1997 and $21,669 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Northbrook Apartments, Ltd. is a Mississippi limited partnership which
raised net proceeds of approximately $1,600,000 in 1979 through a private
offering. The promoter for the private offering of your partnership was Angeles
Real Estate Corp. Insignia acquired your partnership in November 1992. AIMCO
acquired Insignia in October, 1998. There are currently a total of 31 limited
partners of your partnership and a total of 31 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on September 28, 1979 for the purpose of owning
and operating a single apartment property located in Ridgeland, Mississippi,
known as "Pinebrook Apartments." Your partnership's property consists of 160
apartment units. There are 192 one-bedroom apartments and 252 two-bedroom
apartments. Your partnership's property had an average occupancy rate of
approximately 95% in 1996 and 95% in 1997.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1992, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $42,282, $42,038 and $21,669, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2015
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $2,460,180, payable to FNMA and GMAC, which bears interest at a
rate of 7.83%. The mortgage debt is due in October 2003. Your partnership also
has a second mortgage note outstanding of $80,325, on the same terms as the
current mortgage note. Your partnership's agreement of limited partnership also
allows the general partner of your partnership to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $386,582 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership are
not liable, responsible or accountable in damages or otherwise to your
partnership or the limited partner for any acts performed by any of them within
the scope of the authority conferred upon it by your partnership's agreement of
limited partnership, provided that such course of conduct did not constitute
gross negligence or willful misconduct. As a result, unitholders might have a
more limited right of action in certain circumstances than they would have in
the absence of such a provision in your partnership's agreement of limited
partnership. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest".
 
     The general partner is entitled to indemnification by your partnership for
any act performed by it within the scope of the authority conferred upon them by
your partnership's agreement of limited partnership, which does not constitute
gross negligence or willful misconduct. Such indemnity will be paid out of and
to the extent of your partnership assets. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Northbrook Partners,
Limited as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with SEC regulations related to interim
financial information and presented on an income tax basis. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Northbrook Partners, Limited:
 
     We have audited the consolidated statement of assets, liabilities and
partners' deficit -- income tax basis of Northbrook Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1997, and
the related consolidated statements of revenues and expenses and changes in
partners' deficit -- income tax basis and cash flows -- income tax basis for the
year then ended. These consolidated financial statements are the responsibility
of the partnership's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting Northbrook Partners, Limited uses for
Federal income tax purposes, which is a comprehensive basis of accounting other
than generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Northbrook
Partners, Limited and its limited partnership interest as of December 31, 1997,
and the result of their operations and their cash flows for the year then ended,
on the basis of accounting described in Note A.

                         STATEMENTS -- INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of Northbrook
Partners, Ltd. (the "Partnership"), and its Limited Partnership interest in
Northbrook Apartments, Ltd, (the "Project Partnership"). The Partnership was
organized solely to invest in the Project Partnership. The Project Partnership
owns and operates a 160 unit garden apartment complex located in Madison County,
Mississippi.
 
     The Partnership was organized as a Mississippi limited partnership on
September 21, 1979. The General Partner of the Partnership is Angeles
Properties, Inc. ("API"), which acts as a general partner in other limited
partnerships and is an affiliate of Angeles MAE Ventures, Inc., the general
partner of the Project Partnership. Pursuant to the terms of the Agreement and
Amended Certificate of Limited Partnership (the "Agreement"), the General
Partner has contributed $100,000 to the Partnership for which it is entitled to
a 1% interest in the operating profits, losses, credits and cash distributions
of the Partnership.
 
     Capital contributions of the limited partners aggregated $1,600,000.
Pursuant to the terms of the Agreement, the limited partners will receive a 99%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership has made capital contributions of $1,161,000 to the Project
Partnership and is entitled to a 99% interest in the operating profits, losses,
credits and cash distributions of the Project Partnership. MAE Ventures, Inc. is
entitled to the remaining 1% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership's tax returns. The tax basis used differs from GAAP primarily
because on the tax basis (1) certain rental income received in advance is
recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, (3) syndication costs are carried at their original value,
instead of being amortized over the estimated life of assets, and (4) income is
recorded at the partnership level based on the partnership agreement and the
Internal Revenue Code instead of being recorded based on the percentage of
ownership interest.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

                 STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property.
 
  Other Assets
 
     Other assets at December 31, 1997, include unamortized deferred loan costs
of $69,015, which are amortized over the term of the related borrowing. The
amortization expense is included in interest on the statement of revenues and
expenses and changes in partners' deficit. Deferred loan costs are shown net of
accumulated amortization. Also included in other assets at December 31, 1997,
are syndication costs of $128,000 which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
NOTE B -- RESTRICTED ESCROWS
 
     Reserve Escrow -- In conjunction with the refinancing of the Project
Partnership's property in 1993, a general reserve escrow account was established
for certain capital improvements. The funds are used for certain repair work,
debt service, expenses and property taxes or insurance. At December 31, 1997,
the balance in the account was $69,813. The funds in the reserve escrow exceed
the minimum balance required to be maintained by the lender during the term of
the loan.
 
NOTE C -- MORTGAGE NOTES PAYABLE
 
     Mortgage notes payable at December 31, 1997, consist of the following:

     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid principal
balance at the time of prepayment or the present value of the excess of interest
which would be incurred at the stated rate under the notes over the interest
which would be incurred at the Treasury constant maturity for U.S. Government
obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the General Partner for the management
and administration of all partnership activities. The Project Partnership is
obligated to pay a property management fee equal to 5% of gross monthly
collections. In addition to the management fee, the partnership agreement
provides for payments to the General Partner of a partnership administration fee
and reimbursement of certain expenses incurred by the General Partner and its
affiliates on behalf of the Partnership and the Project Partnership.
 
     Transactions with the General Partner and its affiliates are as follows:

Property management fee.....................................  $42,038
Reimbursement for services of affiliates....................  $22,906
</TABLE>
 
     In addition, the General Partner is entitled to a partnership management
fee equal to 5% of the Partnership's adjusted cash from operations as
distributed, pursuant to the partnership agreement. The General Partner was
entitled to a $6,805 partnership management fee during 1997.
 
     For the period from January 1, 1997, to August 31, 1997, the Partnership
insured its property under a master policy through an agency and insurer
unaffiliated with the General Partner. An affiliate of the General Partner
acquired, in the acquisition of a business, certain financial obligations from
an insurance agency which was later acquired by the agent who placed the master
policy. The agent assumed the financial obligations to the affiliate of the
General Partner, who received payments on these obligations from the agent. The
amount of the Partnership's insurance premiums that accrued to the benefit of
the affiliate of the General Partner by virtue of the agent's obligations was
not significant.

of the partnership's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audit.

                         STATEMENTS -- INCOME TAX BASIS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of Northbrook
Partners, Ltd. (the "Partnership"), and its Limited Partnership interest in
Northbrook Apartments, Ltd. (the "Project Partnership"). The Partnership was
organized solely to invest in the Project Partnership. The Project Partnership
owns and operates a 160 unit garden apartment complex located in Madison County,
Mississippi.
 
     The Partnership was organized as a Mississippi limited partnership on
September 21, 1979. The General Partner of the Partnership is Angeles
Properties, Inc. ("API"), which acts as a general partner in other limited
partnerships and is an affiliate of Angeles Investment Properties, Inc.
("AIPI"), the general partner of the Project Partnership. Pursuant to the terms
of the Agreement and Amended Certificate of Limited Partnership (the
"Agreement"), the General Partner has contributed $100,000 to the Partnership
for which it is entitled to a 1% interest in the operating profits, losses,
credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $1,600,000.
Pursuant to the terms of the Agreement, the limited partners will receive a 99%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership has made capital contributions of $1,161,000 to the Project
Partnership and is entitled to a 99% interest in the operating profits, losses,
credits and cash distributions of the Project Partnership. AIPI is entitled to
the remaining 1% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership's tax returns. The tax basis used differs from GAAP primarily
because on the tax basis (1) certain rental income received in advance is
recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, (3) syndication costs are carried at their original value,
instead of being amortized over the estimated life of assets, and (4) income is
recorded at the partnership level based on the partnership agreement and the
Internal Revenue Code instead of being recorded based on the percentage of
ownership interest.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

                 STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property.
 
  Other Assets
 
     Other assets at December 31, 1996 include deferred loan costs of $80,932,
which are amortized over the term of the related borrowing. Deferred loan costs
are shown net of accumulated amortization. Also included in other assets at
December 31, 1996 are syndication costs of $128,000 which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
NOTE B -- RESTRICTED ESCROWS
 
     Capital Improvement -- In conjunction with the refinancing of the Project
Partnership's property in 1993, a capital improvement escrow account was
established for certain capital improvements. The capital improvements were
completed in calendar year 1996 and any excess funds were returned for property
operations.
 
     Reserve Escrow -- Also established with the refinancing was a general
reserve escrow. The funds are used for certain repair work, debt service,
expenses and property taxes or insurance. At December 31, 1996, the balance in
the account was $66,943. The funds in the reserve escrow exceed the minimum
balance required to be maintained by the lender during the term of the loan.
 
NOTE C -- MORTGAGE NOTES PAYABLE
 
     Mortgage notes payable at December 31, 1996 consist of the following:

</TABLE>
 
     Subsequent to November 15, 1996, the principal balance of the mortgage
notes may be prepaid in whole upon payment of a penalty of the greater of one
percent of the unpaid principal balance at the time of prepayment or the present
value of the excess of interest which would be incurred at the stated rate under
the notes over the interest which would be incurred at the Treasury constant
maturity for U.S. Government obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the general partners for the
management and administration of all partnership activities. The Project
Partnership is obligated to pay a property management fee equal to 5% of gross
monthly collections. In addition to the management fee, the partnership
agreement provides for payments to general partners of a partnership
administration fee and reimbursement of certain expenses incurred by general
partners on behalf of the Partnership and the Project Partnership.
 
     Transactions with the General Partner and its affiliates are as follows:
 
<TABLE>

                                                               1996

Property management fee.....................................  $42,282
Reimbursement for services to affiliates....................  $25,074
</TABLE>
 
     The Partnership insures its properties under a master policy through an
agency and insurer unaffiliated with the General Partner. An affiliate of the
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the General Partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the General Partner by
virtue of the agent's obligations is not significant.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Northbrook Partners, Limited:
 
     We have audited the consolidated statements of assets, liabilities and
partners' deficit -- income tax basis of Northbrook Partners, Limited (a limited
partnership) and its limited partnership interest as of December 31, 1995 and
1994, and the related consolidated statements of revenues and expenses and
changes in partners' deficit -- income tax basis and cash flows -- income tax
basis for the years then ended. These consolidated financial statements are the
responsibility of the partnership's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     As described in Note A, these consolidated financial statements were
prepared on the basis of accounting Northbrook Partners, Limited uses for
Federal income tax purposes, which is a comprehensive basis of accounting other
than generally accepted accounting principles.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Northbrook
Partners, Limited and its limited partnership interest as of December 31, 1995
and 1994, and the result of their operations and their cash flows for the years
then ended, on the basis of accounting described in Note A.

                           DECEMBER 31, 1995 AND 1994
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The consolidated financial statements include the accounts of Northbrook
Partners, Ltd. (the "Partnership"), and its Limited Partnership interest in
Northbrook Apartments, Ltd. (the "Project Partnership"). The Partnership was
organized solely to invest in the Project Partnership. The Project Partnership
owns and operates a 160 unit garden apartment complex located in Madison County,
Mississippi.
 
     The Partnership was organized as a Mississippi limited partnership on
September 21, 1979. The General Partner of the Partnership is Angeles
Properties, Inc. ("API"), which acts as a general partner in other limited
partnerships and is an affiliate of Angeles Investment Properties, Inc.
("AIPI"), the general partner of the Project Partnership. Pursuant to the terms
of the Agreement and Amended Certificate of Limited Partnership (the
"Agreement"), the General Partner has contributed $100,000 to the Partnership
for which it is entitled to a 1% interest in the operating profits, losses,
credits and cash distributions of the Partnership.
 
     Capital contributions of the limited partners aggregated $1,600,000.
Pursuant to the terms of the Agreement, the limited partners will receive a 99%
interest in the operating profits, losses, credits and cash distributions of the
Partnership.
 
     The Partnership has made capital contributions of $1,161,000 to the Project
Partnership and is entitled to a 99% interest in the operating profits, losses,
credits and cash distributions of the Project Partnership. AIPI is entitled to
the remaining 1% of the same.
 
  Basis of Accounting
 
     The consolidated financial statements are prepared on the basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The consolidated financial
statements represent the combination of both the Partnership and Project
Partnership's tax returns. The tax basis used differs from GAAP primarily
because on the tax basis (1) certain rental income received in advance is
recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, (3) syndication costs are carried at their original value,
instead of being amortized over the estimated life of assets, and (4) subsidiary
income is recorded at the partnership level based on the partnership agreement
and the Internal Revenue Code instead of being recorded based on the percentage
of ownership interest.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.

                 STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property.
 
  Other Assets
 
     Other assets at December 31, 1995 and 1994 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization. Also included in other assets at December 31, 1995
and 1994 are $128,000 of syndication costs which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers cash and
all highly liquid investments, with an original maturity of three months or less
when purchased, to be cash and cash equivalents.
 
NOTE B -- LONG-TERM RECEIVABLE -- AFFILIATE
 
     In July 1993, Angeles Mortgage Investment Trust ("AMIT"), a real estate
investment trust, initiated litigation against the Partnership and other
partnerships which loaned money to AMIT seeking to avoid repayment of such
obligations. The Partnership subsequently filed a counterclaim against AMIT
seeking to enforce the obligation, the principal amount of which is $135,000
plus accrued interest from March 1993 ("AMIT Obligation"). In 1993, the
Partnership wrote off this receivable as a bad debt.
 
     MAE GP Corporation ("MAE GP"), an affiliate of the general partners, owns
1,675,113 Class B Shares of AMIT. MAE GP has the option to convert these Class B
Shares, in whole or in part, into Class A Shares on the basis of 1 Class A Share
for every 49 Class B Shares. These Class B Shares entitle MAE GP to receive 1.2%
of the distributions of net cash distributed by AMIT. These Class B Shares also
entitle MAE GP to vote on the same basis as Class A Shares which allows MAE GP
to vote approximately 37% of the total shares (unless and until converted to
Class A Shares at which time the percentage of the vote controlled represented
by the shares held by MAE GP would approximate 1.2% of the vote). Between the
date of acquisition of these shares (November 24, 1992) and March 31, 1995, MAE
GP has declined to vote these shares. Since that date, MAE GP voted its shares
at the 1995 annual meeting in connection with the election of trustees and other
matters. MAE GP has not exerted and continues to decline to exert any management
control over or participate in the management of AMIT. However, MAE GP may
choose to vote these shares as it deems appropriate in the future. In addition,
Liquidity Assistance, LLC, ("LAC"), an affiliate of the Managing General Partner
and an affiliate of Insignia Financial Group, Inc., which provides property
management and partnership administration services to the Partnership, owns
63,200 Class A Shares of AMIT. These Class A Shares entitle LAC to vote
approximately 1.5% of the total shares.
 
     On November 9, 1994, the Partnership executed a definitive Settlement
Agreement to settle the dispute with respect to the AMIT Obligation. The actual
closing of the Settlement occurred April 14, 1995. The Partnership's claim was
satisfied by a cash payment to the Partnership totaling $113,041 (the
"Settlement Amount") at closing. Income is recorded in 1995 equal to the cash
payment and is included in other income.
 
     As part of the above described settlement, MAE GP granted to AMIT an option
to acquire the Class B shares owned by it. This option can be exercised at the
end of 10 years or when all loans made by AMIT to partnerships affiliated with
MAE GP as of November 9, 1994 (which is the date of execution of a definitive
Settlement Agreement), have been paid in full, but in no event prior to November
9, 1997. AMIT delivered to MAE GP cash in the sum of $250,000 at closing, which
occurred April 14, 1995, as payment for the option. Upon exercise of the option,
AMIT would remit to MAE GP an additional $94,000.

                 STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
     Simultaneously with the execution of the option, MAE GP executed an
irrevocable proxy in favor of AMIT the result of which is MAE GP will be able to

NOTE E -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership and the Project Partnership have no administrative or
management employees and are dependent on the general partners for the
management and administration of all partnership activities. The Project
Partnership is obligated to pay a property management fee equal to 5% of gross
monthly collections. In addition to the management fee, the partnership
agreement provides for payments to general partners of a partnership
administration fee and reimbursement of certain expenses incurred by general
partners on behalf of the Partnership and the Project Partnership.
 
     Transactions with the General Partner and its affiliates are as follows:

     The Partnership insures its properties under a master policy through an
agency and insurer unaffiliated with the General Partner. An affiliate of the
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the General Partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the General Partner by
virtue of the agent's obligations is not significant.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2454
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2455
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Olde Mill Investors Limited Partnership. For each unit that you tender, you
     may choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49   states, the District of Columbia and
     Puerto Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million,
     total debt of $1,314 million and stockholders' equity of $1,394 million. On
     a pro forma basis, giving effect to our recently completed merger with
     Insignia Financial Group, Inc. and related transactions, as of June 30,
     1998, AIMCO had total assets of $3,972 million, total debt of $1,626
     million and stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2460
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2461
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $1,545.30 per unit for the year
     ended December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $     per year on the number of Tax-Deferral
       % Preferred OP Units or distributions of $     per year on the number of
     Tax-Deferral Common OP Units that you would receive in an exchange for each
     of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   2463
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on          ,
1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-     of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2466
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   2467
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   2468
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   2469
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   2470
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 16.25% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   2471
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   2476
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. [leave blank]
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $254,423 in 1996, $313,723 in 1997 and $136,838 for
the first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Olde Mill Investors Limited Partnership
is a Delaware limited partnership which was formed on December 30, 1985 for the
purpose of owning and operating a small number of apartment properties located
in Beltsville, Maryland, known as "Lighthouse at Twin Lakes Apartments I,"
"Lighthouse at Twin Lakes Apartments II" and "Lighthouse at Twin Lakes
Apartments III," respectively. In 1986, it completed a private placement of
units that raised net proceeds of approximately $20,577,920. Lighthouse at Twin
Lakes Apartments I consists of 480 apartment units, Lighthouse at Twin Lakes
Apartment II consist of 58 apartment units and Lighthouse at Twin Lakes
Apartments III consists of 107 apartment units. Your partnership has no

     Property Management. Since November 199 , your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2030, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $18,259,405, payable to LaSalle and
Lehman, which bears interest at a rate of 8.75%. The mortgage debt is due in
September 2006. Your partnership's agreement of limited partnership also allows
your general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six

     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2485
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   2486
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June, 1998 were $          per unit (equivalent
to $          on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 16.25% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   2488
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   2489
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2491
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2492
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   2493
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   2494
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of considerations being offered, or increasing or decreasing the
percentage of outstanding units being sought. Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   2496
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

<PAGE>   2498
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   2499
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   2501
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income gain will be made to any
holder of Junior Units upon the liquidation, dissolution or winding up of the
AIMCO Operating Partnership. If, upon any liquidation, dissolution or winding up
of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units
 
                                      S-43
<PAGE>   2502
 
     ratably in the same proportion as the respective amounts that would be
payable on such Preferred OP Units and any such Parity Units if all amounts
payable thereon were paid in full. A voluntary or involuntary liquidation,
dissolution or winding up of the AIMCO Operating Partnership will not include a
consolidation or merger of the AIMCO Operating Partnership with one or more
partnerships, corporations or other entities, or a sale or transfer of all or
substantially all of the AIMCO Operating Partnership's assets. Upon any
liquidation, dissolution or winding up of the AIMCO Operating Partnership, after
all allocations shall have been made in full to the holders of Preferred OP
Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   2504
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   2509
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   2510
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In addition, we considered the recent decline in the market for equity
securities, including those of REITs, and the decline in the availability of
commercial mortgage financing. Although the direct capitalization method is a
widely accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   2512
 
     - Third, using this net equity value, we determined the proceeds that would

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   2513
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the six months ended June, 1998 were $          equivalent to
     $          on an annualized basis). This is equivalent to distributions of
     $          per year on the number of Tax-Deferral      % Preferred OP
     Units, or distributions of $          per year on the number of Tax-
     Deferral Common OP Units, that you would receive in exchange for each of
     your partnership's units. Therefore, distributions with respect to the
     Preferred OP Units and Common OP Units that we are offering are expected to
     be        , immediately following our offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   2514
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

sold and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Price............................................    $

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   2518
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fees
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $254,423 in 1996, $313,723 in 1997 and $136,838 for
the first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $254,423, $313,723 and $136,838, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS

liquidate, sell, finance or refinance your partnership's property within any
specified time period.

and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is not is

financing obtained by your partnership within the established borrowing
restrictions.

     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, there was current mortgage note outstanding
on "Lighthouse at Twin Lakes Apartments" of $18,259,405 payable to LaSalle and
Lehman which bears interest at a rate of 8.75% and is due September 2006. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates will not incur any liability, responsibility or accountability
for damages or otherwise to your partnership or any limited partner arising out
of any acts performed or any omission by any of them if they
 
                                      S-75
<PAGE>   2534
 
     believed in good faith that such act or omission was in the best interests
of your partnership and such course of conduct did not constitute negligence or
misconduct on the part of the such person. As a result, unitholders might have a
more limited right of action in certain circumstances than they would have in
the absence of such a provision in your partnership's agreement of limited
partnership. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest".
 
     Your partnership will indemnify and save harmless the general partner and
its affiliates against any loss, damage, liability, cost or expenses (including
reasonable attorneys' fees) incurred by them in connection with your partnership
provided that such loss, damage, liability, cost or expense was not the result
of negligence or misconduct on the part of such persons. Such indemnity will be
paid from, and only to the extent of, partnership assets. However, the general
partner will not be indemnified from any loss, damage or cost resulting form the
violation of any Federal or state securities law in connection with the sale of
units unless (i) there has been a successful adjudication on the merits of each
count involving such securities law violation, (ii) such claims have been
dismissed with prejudice on the merits by a court of competent jurisdiction or
(iii) a court of competent jurisdiction approves a settlement of such claim. In
such claim for indemnification for Federal or state securities law violation,
the party seeking indemnification must place before the court the position of
the SEC and any other applicable regulatory agency with respect of the issue of
indemnification for securities law violations.
 
     No partnership funds will be used to purchase any insurance that insures
any party against any liability that is prohibited by your partnership's
agreement of limited partnership. As part of its assumption of liabilities in
the consolidation, AIMCO will indemnify the general partner of your partnership
and their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below.

</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale
 
                                      S-76

     transactions (excluding transactions believed to be between related
parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     AIMCO currently owns a 16.25% limited partnership interest in your
partnership. Except as described above, Neither AIMCO, nor, to the best of its
knowledge, any of its affiliates, (i) beneficially own or have a right to
acquire any units, (ii) have effected any transaction in the units, or (iii)
have any contract, arrangement, understanding or relationship with any other
person with respect to any securities of your partnership, including, but not
limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.

includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Olde Mill Investors
Limited Partnership and Subsidiaries as of June 30, 1998 and for the six months
ended June 30, 1998 and 1997 have been prepared in accordance with generally
accepted accounting principles for interim financial information. Accordingly,
they do not include all the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
Olde Mill Investors Limited Partnership and Subsidiaries
 
     We have audited the accompanying consolidated balance sheets of Olde Mill
Investors Limited Partnership and Subsidiaries as of December 31, 1997 and 1996,
and the related consolidated statements of operations, changes in partners'
equity (deficit) and cash flows for the years then ended. These consolidated
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Olde Mill
Investors Limited Partnership and Subsidiaries as of December 31, 1997 and 1996,
and the results of their operations and their cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Olde Mill Investors Limited Partnership and Subsidiaries (the "Investor
Partnership"), a Delaware limited partnership, was formed in 1985 to acquire a
99.99% general partnership interest in Calverton Construction Company Limited
Partnership, Calverton Associates Limited Partnership and Walden Joint Venture
Limited Partnership (the "Operating Partnerships"). The Operating Partnerships
collectively own and operate a 700-unit apartment complex located in Beltsville,
Maryland (the "Property") and is operating under the name of Light House at Twin
Lakes I, II and III (previously Olde Mill Landing). The Investor Partnership and
Operating Partnerships will terminate on December 31, 2030, or earlier upon the
occurrence of certain events specified in the Partnership Agreements.
 
     The general partner of the Investor Partnership is Winthrop Financial
Associates, A Limited Partnership, a Maryland Limited Partnership ("WFA"). The
initial limited partner of the Investor Partnership was Three Winthrop
Properties, Inc. ("Three Winthrop"). Three Winthrop Properties, Inc. is the
limited partner of the Operating Partnerships.
 
     Profits and cash flow from normal operations, in general, are allocated 8%
to WFA and 92% to the Investor Limited Partners and losses are allocated 1% to
WFA and 99% to the Investor Limited Partners. After distributions of certain
priority items, Investor Partnerships Residuals will be distributed 20% to WFA
and 80% to the Investor Limited Partners.
 
  Basis of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
the Partnership and the Operating Partnerships prepared on the accrual basis of
accounting. Three Winthrop's ownership in the Operating Partnerships has been
reflected as a minority interest in the accompanying consolidated balance sheets
and statements of operations. All significant intercompany accounts and
transactions have been eliminated in consolidation.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. Depreciation of rental
property is provided using the straight-line method over the useful lives of
each class of depreciable property. For income tax reporting, accelerated
methods and lives are used.
 
     Buildings, improvements and personal property consist of the following as
of December 31, 1997 and 1996:

  Deferred Costs
 
     Deferred costs consist of financing costs which are amortized over the term
of the related mortgage, using the straight-line method.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Rental Income
 
     Rental income is recognized as rents become due. Rental payments received
in advance are deferred until earned. All leases between the operating
partnerships and tenants of the property are operating leases.
 
  Income Taxes
 
     No provision has been made for income taxes in the consolidated financial
statements. The Partners are required to report on their individual income tax
returns their allocable share of taxable income, gains, losses, deductions and
credits. Each Partnership files its own tax return on the accrual basis.
 
  Cash Equivalents
 
     For purpose of the consolidated statement of cash flows, the partnership
considers all highly liquid investments of $242,183 be cash equivalents. The
carrying amount approximates fair value because of the short maturity of this
instrument.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
NOTE B -- MORTGAGES PAYABLE
 
     The investor partnership obtained a $15,300,000 loan from GMAC Commercial
Mortgage (GMAC) pursuant to a loan program of the Federal National Mortgage
Association (FNMA). The loan bore interest at the rate of 10.625% per annum and
was payable in monthly principal and interest payments of $141,849 through March
1, 1996. The loan was secured by a first mortgage on Phases I, II and IV of the
property. On February 27, 1996, FNMA agreed to extend the maturity of the loan
to September 1, 1996.
 
     One of the operating partnerships obtained a $3,036,400 loan that was
insured by HUD and collateralized by Phase III of the project. The loan bore
interest at the rate of 7.5% per annum and was payable in monthly principal and
interest payments of $19,982 through July 2019.
 
     On August 9, 1996, the three operating partnerships refinanced both
mortgage loans and obtained a $18,500,000 loan with First Union National Bank of
North Carolina which is being serviced by GMAC. The loan bears interest at the
rate of 8.75% per annum and is payable in monthly principal and interest
payments of $145,540 commencing October 1, 1996 through August 1, 2006. On
September 1, 2006, the entire outstanding principal with an approximate balloon
payment of $16,494,409 together with all unpaid interest shall be due and
payable in full. The loan may be prepaid at any time after the fourth
anniversary of the note with a prepayment penalty equal to 1% of the principal
being prepaid.
 
     Under agreements with the mortgage lender, the Operating Partnerships are
required to make monthly escrow deposits of taxes, insurance and replacement of
project assets.
 
     The liability of the Operating Partnerships is limited to the underlying
value of the real estate collateral, plus other amounts deposited with the
lender.

NOTE C -- TAXABLE LOSS
 
     The taxable loss for 1997 and 1996 differs from the net loss for financial

NOTE D -- RELATED PARTY TRANSACTIONS
 
     In connection with the refinancing of the mortgage notes on August 9, 1996,

general partner and the Operating Partnership's limited partner a refinancing

          (a) The property was managed by Winthrop Management through October
              27, 1997, an affiliate of two of the partners. Pursuant to the
              management agreement the operating partnerships paid Winthrop a 5%
              management fee based on gross rental collections of the
              properties. The management fees for the years ended December 31,

              (see note F to the financial statements). The current management
              agreement provides for a property management fee equal to 5% of
              the gross operating revenues generated by the properties. Fees of
              $44,913 were charged to operations for the year ended December 31,

              flow which was included in administrative expenses. The

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
OLDE MILL INVESTORS LIMITED PARTNERSHIP AND SUBSIDIARY
 
     We have audited the accompanying consolidated balance sheets of Olde Mill
Investors Limited Partnership and Subsidiary as of December 31, 1996 and 1995,
and the related consolidated statements of operations, changes in partners'
equity (deficit) and cash flows for the years then ended. These consolidated
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Olde Mill
Investors Limited Partnership And Subsidiary as of December 31, 1996 and 1995,
and the results of their operations and their cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     OLDE MILL INVESTORS LIMITED PARTNERSHIP AND SUBSIDIARY (the "Investor
Partnership"), a Delaware limited partnership, was formed in 1985 to acquire a
99.99% general partnership interest in Calverton Construction Company Limited
Partnership, Calverton Associates Limited Partnership and Walden Joint Venture
Limited Partnership (the "Operating Partnerships"). The Operating Partnerships
collectively own and operate a 700-unit apartment complex located in Maryland
(the "Property"). The Investor Partnership and Operating Partnerships will
terminate on December 31, 2030, or earlier upon the occurrence of certain events
specified in the Partnership Agreements.
 
     The general partner of the Investor Partnership is Winthrop Financial
Associates, A Limited Partnership, a Maryland Limited Partnership ("WFA"). The
initial limited partner of the Investor Partnership was Three Winthrop
Properties, Inc. ("Three Winthrop"). Three Winthrop Properties, Inc. is the
limited partner of the Operating Partnerships.
 
     Profits and cash flow from normal operations, in general, are allocated 8%
to WFA and 92% to the Investor Limited Partners and losses are allocated 1% to
WFA and 99% to the Investor Limited Partners. After distributions of certain
priority items, Investor Partnerships Residuals will be distributed 20% to WFA
and 80% to the Investor Limited Partners.
 
  Basis of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
the Partnership and the Operating Partnerships prepared on the accrual basis of
accounting. Three Winthrop's ownership in the Operating Partnerships has been
reflected as a minority interest in the accompanying consolidated balance sheets
and statements of operations. All significant intercompany accounts and
transactions have been eliminated in consolidation.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. Depreciation of rental
property is provided using the straight-line method over the useful lives of
each class of depreciable property. For income tax reporting, accelerated
methods and lives are used.
 
     Buildings, improvements and personal property consist of the following as
of December 31, 1996 and 1995:

  Deferred Costs
 
     Deferred costs consist of financing costs which are amortized over the term
of the related mortgage, using the straight-line method.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Rental Income
 
     Rental income is recognized as rents become due. Rental payments received
in advance are deferred until earned. All leases between the operating
partnerships and tenants of the property are operating leases.
 
  Income Taxes
 
     No provision has been made for income taxes in the consolidated financial
statements. The Partners are required to report on their individual income tax
returns their allocable share of taxable income, gains, losses, deductions and
credits. Each Partnership files its own tax return on the accrual basis.
 
  Cash Equivalents
 
     For purpose of the consolidated statement of cash flows, the partnership
considers all highly liquid investments of $1,284,565 be cash equivalents. The
carrying amount approximates fair value because of the short maturity of this
instrument.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
NOTE B -- MORTGAGES PAYABLE
 
     The investor partnership obtained a $15,300,000 loan from GMAC Commercial
Mortgage (GMAC) pursuant to a loan program of the Federal National Mortgage
Association (FNMA). The loan bore interest at the rate of 10.625% per annum and
was payable in monthly principal and interest payments of $141,849 through March
1, 1996. The loan was secured by a first mortgage on Phases I, II and IV of the
property. On February 27, 1996, FNMA agreed to extend the maturity of the loan
to September 1, 1996.
 
     On of the operating partnerships obtained a $3,036,400 loan that was
insured by HUD and collateralized by Phase III of the project. The loan bore
interest at the rate of 7.5% per annum and was payable in monthly principal and
interest payments of $19,982 through July 2019.
 
     On August 9, 1996, the three operating partnerships refinanced both
mortgage loans and obtained a $18,500,000 loan with First Union National Bank of
North Carolina which is being serviced by GMAC. The loan bears interest at the
rate of 8.75% per annum and is payable in monthly principal and interest
payments of $145,540 commencing October 1, 1996 through August 1, 2006. On
September 1, 2006, the entire outstanding principal with an approximate balance
of $16,494,409 together with all unpaid interest shall be due and payable in
full. The loan may be prepaid at any time after the fourth anniversary of the
note with a prepayment penalty equal to 1% of the principal being prepared.
 
     Under agreements with the mortgage lender, the Operating Partnerships are
required to make monthly escrow deposits or taxes, insurance and replacement of
project assets.
 
     The liability of the Operating Partnerships is limited to the underlying
value of the real estate collateral, plus other amounts deposited with the
lender.

NOTE D -- RELATED PARTY TRANSACTIONS
 
     In connection with the refinancing of the mortgage notes on August 9, 1996,
mortgage proceeds were used to pay an affiliate of the Investor partnership's
general partner and the Operating Partnership's limited partner a refinancing
fee of $138,750.
 
     The Operating Partnerships have incurred charges by the commitments to
related parties, including:
 
          (a) The property is managed by Winthrop Management, an affiliate of
              two of the partners, pursuant to a management agreement. The
              operating partnerships pay a 5% management fee based on gross
              rental collections of the property. The management fee for the
              years ended December 31, 1996 and 1995 amounted to $254,423 and
              $251,778, respectively.
 
          (b) First Winthrop Corporation, Inc., an affiliate of two of the
              partners, is paid a partnership administration fee in the amount
              of $50,000 per annum out of cash flow which is included in
              administrative expenses.
 
NOTE E -- CONCENTRATION OF CREDIT RISK
 
     At December 31, 1996, the Operating Partnerships have cash in the amount of
$265,904 held by the mortgage lender. This account is insured by the Federal
Deposit Insurance Corporation up to $100,000. The uninsured portion of this
balance at December 31, 1996 is $165,904.

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2562
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2563
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Orchard Park Apartments Limited Partnership. For each unit that you tender,
     you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2568
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2569
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $2,640 per unit for the six months
     ended June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL
 
                                       S-3
<PAGE>   2570
 
     TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX
     CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
     TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX
     MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS
     AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX
     CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if 50% or more of the
     total interests in your partnership are transferred within a 12-month
     period. If we acquire a significant percentage of the interest in your
     partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, if there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using
 
                                       S-4
<PAGE>   2571
 
     our best judgment, but our valuation is just an estimate. Although the
     direct capitalization method is a widely-accepted way of valuing real
     estate, there are a number of other methods available to value real estate,
     each of which may result in different valuations of the property. The
     proceeds that you would receive if you sold your units to someone else or
     if your partnership were actually liquidated might be higher or lower than
     our offer consideration. An actual liquidation may also result in your
     paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the
 
                                       S-5
<PAGE>   2572
 
     expiration of the offer, and you must follow the instructions provided with
     the Letter of Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2574
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   2575
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   2576
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the proposed to be issued by AIMCO
Class I Preferred Stock. At the same time, Moody's confirmed its existing rating
on AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   2577
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.

<PAGE>   2578
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least 50% of the units of your partnership. In
     the absence of such consent, your only option for liquidation of your
     investment would be to sell your units in a private transaction. Any such
     sale could be at a very substantial discount from your pro rata share of
     the fair market value of your partnership's property and might involve
     significant expense and delay.
 
                                      S-12
<PAGE>   2579
 
        Continuation of Your Partnership Without the Offer. A second alternative
     would be for your partnership to continue its business without our offer. A
     number of advantages could result from the continued operation of your
     partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources. Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your partnership without the offer
     would deny you and your partners the benefits that your general partner
     expects to result from the offer. For example, a partner of your
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                      S-13
<PAGE>   2580
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any

     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and
 
                                      S-15
<PAGE>   2582
 
     expenses in making the offer (excluding the purchase price of the units
payable to you and your partners) will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

Class A Common Stock on the NYSE on a recent date before we commenced this

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $61,972 in 1996, $57,524 in 1997 and $30,346 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.

     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Orchard Park Apartments Limited
Partnership is a South Carolina limited partnership which was formed on 1983 for
the purpose of owning and operating a single apartment property located in
Greenville, South Carolina, known as "Orchard Park Apartments". In 1983, it
completed a private placement of units that raised net proceeds of approximately
$2,675,000. Orchard Park Apartments consists of 172 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2013, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,696,697, payable to Life Insurance Co.
of Georgia, which bears interest at a rate of 9.75%. The mortgage debt is due in
August 2014. Your partnership's agreement of limited partnership also allows
your general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in
 
                                      S-26
<PAGE>   2593
 
respect of such units on or after the date on which we accept such units for
purchase. Accordingly, following the purchase of your units, we would be
entitled to receive any future distributions from the operations of your
partnership to the extent of the units we acquire. Similarly, if you tender your
units for OP Units, you will be entitled to future distributions from the
operations of the AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     The particular tax consequences for you of our offer will depend upon a
number of factors related to your tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership (and
therefore are no longer subject to the "passive" loss rules with respect to your
partnership). Because the income tax consequences of tendering units will not be
the same for everyone, you should consult your own tax advisor with specific
reference to your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.

     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $0 per unit. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX
PURPOSES. If there is a sale or exchange of 50% or more of the total interest in
capital and profits of your partnership within any 12-month period, including
sales or exchanges resulting from the offer, your partnership will terminate for
Federal income tax purposes. Any such termination may, among other things,
subject the assets of your partnership to
 
                                      S-28
<PAGE>   2595
 
longer depreciable lives than those currently applicable to the assets of your
partnership. This would generally decrease the annual average depreciation
deductions allocable to you if you do not tender all of your units (thereby
increasing the taxable income allocable to your units each year), but would have
no effect on the total depreciation deductions available over the useful lives
of the assets of your partnership. Any such termination may also change (and
possibly shorten) your holding period with respect to your units that you choose
to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
                                      S-29
<PAGE>   2596
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 50% of the units of your partnership. In the absence
of such consent, your only option for liquidation would be to sell your units in
a private transaction. Any such sale likely would be at a very substantial
discount from your pro rata share of the fair market value of your partnership's
property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership may require funding from its partners. Continuation of
its operations may be dependent on additional funding from partners or from
other sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our
 
                                      S-30
<PAGE>   2597
 
offer would deny you and your partners the benefits of diversification into a
company which has a much larger and more diverse portfolio of apartment
properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2599
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2600
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   2601
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   2602
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   2603
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to your partnership's business, or that certain
parts of your partnership's business might not have to be disposed of or other
substantial conditions complied with in order to obtain such approval or action,
any of which could cause the
 
                                      S-40
<PAGE>   2607
 
     AIMCO Operating Partnership to elect to terminate the offer without
purchasing units hereunder. The AIMCO Operating Partnership's obligation to
purchase and pay for units is subject to certain conditions, including
conditions related to the legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts
 
                                      S-41
<PAGE>   2608
 
     distributable upon liquidation, dissolution or winding up in preference or
priority to the holders of such interest (the Common OP Units and such other
interests are collectively referred to herein as "Junior Units"); (ii) on a
parity with the Class B Partnership Preferred Units, the Class C Partnership
Preferred Units, the Class D Partnership Preferred Units, the Class G
Partnership Preferred Units, the Class H Partnership Preferred Units, and with
any other interest in the AIMCO Operating Partnership if the holders of such
interest and the Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in proportion to their respective amounts of accumulated, accrued and unpaid
distributions or stated preferences, without preference or priority of one over
the other ("Parity Units"); and (iii) junior to the Class F Partnership
Preferred Units and any other interest in the AIMCO Operating Partnership if the
holders of such interest shall be entitled to the receipt of distributions or
amounts distributable upon liquidation, dissolution or winding up in preference
or priority to the holders of the Preferred OP Units ("Senior Units"). Junior
Units, Parity Units and Senior Units may be issued from time to time by the
AIMCO Operating Partnership without any approval or consent by holders of the
Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for

     such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.

REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   2612
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   2617
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   2618
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   2621
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-55
<PAGE>   2622
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units were $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the six months ended June 30, 1998 were $0. Therefore, distributions
     with respect to the Preferred OP Units and Common OP Units that we are
     offering are expected to be        , immediately following our offer, than
     the distributions with respect to your units. See "Comparison of Ownership
     of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-56
<PAGE>   2623
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   2624
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
                                      S-58

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF MATERIALS CONSIDERED
 
     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and
through June 30, 1998; (v) reviewed operating budgets for your partnership's
property for 1998, as prepared by your partnership; (vi) reviewed information
prepared by management relating to any debt encumbering your partnership's
property; (vii) reviewed information regarding market rental rates and
conditions for apartment properties in the general market area of your
partnership's property and other information relating to acquisition criteria

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred

     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by

     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.

     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the

connection with the offer is fair to the unitholders from a financial point of
view.

and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity and fees for additional
services. The property manager received management fees of $61,972 in 1996,
$57,524 in 1997 and 30,346 for the first six months of 1998. The AIMCO Operating
Partnership has no current intention of changing the fee structure for the
manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Orchard Park Apartments Limited Partnership is a South Carolina limited
partnership which raised net proceeds of approximately $2,675,000 in 1983
through a private offering. The promoter for the private offering of your
partnership was US Shelter Corporation. Insignia acquired your partnership in
December 1990. AIMCO acquired Insignia in October, 1998. There are currently a
total of 48 limited partners of your partnership and a total of 50 units of your
partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
single apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on 1983 for the purpose of owning and operating
a single apartment property located in Greenville, South Carolina, known as
"Orchard Park Apartments." Your partnership's property consists of 172 apartment
units. There are 80 one-bedroom apartments and 92 two-bedroom apartments. The
total rentable square footage of your partnership's property is 146,708 square
feet. Your partnership's property had an average occupancy rate of approximately
97.09% in 1996 and 97.09% in 1997. The average annual rent per apartment unit is
approximately $6,283.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $61,972, $57,524 and $30,346, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2013
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,696,697, payable to Life Insurance Co. of Georgia, which bears
interest at a rate of 9.75%. The mortgage debt is due in August 2014. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $170,314 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable to your partnership or any limited partner for any
loss or damage that may be caused by any acts performed or any failure to act by
any of them if such acts were done in good faith pursuant to authority granted
to promote the interests of your partnership, which do not constitute fraud,
gross negligence or willful misconduct. Moreover, the general partner is not
liable to your partnership or the limited partner because any taxing authorities
disallowed or adjusted any deductions or credits in your partnership income tax
return. As a result, unitholders might have a more limited right of action in
certain circumstances than they would have in the absence of such a provision in
your partnership's agreement of limited partnership. The general partner of your
partnership is owned by AIMCO. See "Conflicts of Interest."
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss or damage resulting from any act or omission
performed or omitted in good faith and in accordance with the authority granted
to it to promote the interests of your partnership; provided that such acts do
not constitute fraud, gross negligence or intentional misconduct. As part of its
assumption of liabilities in the consolidation, AIMCO will indemnify the general
partner of your partnership and their affiliates for periods prior to and
following the consolidation to the extent of the indemnity under the terms of
your partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not made any distributions in the last five years.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation and distributions that would have
been paid to the general partner of your partnership, or the company paid to the
property manager or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Orchard Park Apartments
Limited Partnership as of June 30, 1998 and for the six months ended June 30,
1998 and 1997 have been prepared in accordance with the accounting basis for
Federal income tax reporting. Accordingly, they do not include all the
information and footnotes required by the accounting basis for Federal income
tax reporting for complete financial statements. In the opinion of management,
all adjustments considered necessary for a fair presentation have been included
and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2655
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2656
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Park Towne Place Associates Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2661
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2662
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
       Historically, the quarterly distributions paid on the Tax-Deferral Common
       OP Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership has not made a distribution in the past 5 years. We will
     pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION

     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   2664
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2667
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   2668
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   2669
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   2670
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   2671
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 0% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least 50% of the partners units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   2672
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Tax-Deferral      % Preferred Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,

                                      S-14
<PAGE>   2674
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY

SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR
TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN

CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO
YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   2677
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, unlike the general partner of the AIMCO Operating Partnership,
the general partner of your partnership is entitled to compensation for its
services as general partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $60,000
in 1986, increasing annually at a rate of 6% and 20% of Cash Flow for any year
in which Cash Flow exceeds the forecasted amount for such year and may receive
reimbursement for expenses generated in such capacity. The property manager
received management fees of $203,451 in 1996, $196,956 in 1997 and $169,162 for
the first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future

     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2035, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $38,082,898, payable to First Union and
La Salle, which bears interest at a rate of 9.13%. The mortgage debt is due in
November 2006. Your partnership's agreement of limited partnership also allows
your general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2686
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   2687
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25. Distributions with respect to your
units for the six months ended June, 1998 were $0.00 per unit. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   2688
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   2689
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 50% of the partners units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
                                      S-30
<PAGE>   2690
 
       However, one class of outstanding Partnership Preferred Units has prior
       distribution rights and the Tax-Deferral   % Preferred OP Units rank
       equal to six other outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your units
       since the inception of your partnership. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2692
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2693
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole
 
                                      S-34
<PAGE>   2694
 
discretion, which determination shall be final and binding on all parties. The
AIMCO Operating Partnership reserves the absolute right to reject any or all
tenders of any particular unit determined by it not to be in proper form or if
the acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final
 
                                      S-35

and binding on all parties. Neither the AIMCO Operating Partnership, the
Information Agent nor any other person will be under any duty to give
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   2696
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

units tendered, and may terminate or amend the offer if at any time from or

any such units (whether or not any units have theretofore been accepted for
payment and paid for) pursuant to the offer, any of the following shall occur:

     including any fire, flood, natural disaster, casualty loss, or act of God
     that, which change, in the sole judgment of the AIMCO Operating
     Partnership, is or may be materially adverse to your partnership or the
     value of your units to the AIMCO Operating Partnership, or the AIMCO
     Operating Partnership shall have become aware of any facts relating to your
     partnership, its indebtedness or its operations which, in the sole judgment

     the S&P 500 Index, the Morgan Stanley REIT Index, or the price of the
     10-year Treasury Bond or the price of the 30-year Treasury Bond, in each
     case from             , 1998, (iv) any material adverse change in the

     Operating Partnership, might affect the extension of credit by banks or
     other lending institutions, or (viii) in the case of any of the foregoing
     existing at the time of the commencement of the offer, in the sole judgment
     of the AIMCO Operating Partnership, a material acceleration or worsening
     thereof; or
 
          (c) there shall have been threatened, instituted or pending any
     action, proceeding, application or counterclaim by any Federal, state,
     local or foreign government, governmental authority or governmental agency,

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be
 
                                      S-40
<PAGE>   2700
 
     obtained without substantial conditions or that adverse consequences might
not result to your partnership's business, or that certain parts of your
partnership's business might not have to be disposed of or other substantial
conditions complied with in order to obtain such approval or action, any of
which could cause the AIMCO Operating Partnership to elect to terminate the
offer without purchasing units hereunder. The AIMCO Operating Partnership's
obligation to purchase and pay for units is subject to certain conditions,
including conditions related to the legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $          .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   2702
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   2703
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   2705
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   2710
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   2711
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   2713
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   2714
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25. Distributions with respect to your units for
     the six months ended June, 1998 were $0.00 per unit. Therefore,
     distributions with respect to the Preferred OP Units and Common OP Units
     that we are offering are expected to be        , immediately following our
     offer, than the distributions with respect to your units. See "Comparison
     of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   2715
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   2716
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
                                      S-57

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   2719
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer consideration for you, even as a subsidiary of AIMCO. It also has a
duty to remove the property manager for your partnership's property, under
certain circumstances, even though the property manager is also an affiliate of
AIMCO. The conflicts of interest include the fact that a decision to remove, for
any reason, the general partner of your partnership from its current position as
a general partner of your partnership would result in a decrease or elimination
of the substantial management fees paid to an affiliate of the general partner
of your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $60,000
in 1986, increasing annually at a rate of 6% and 20% of Cash Flow for any year
in which Cash Flow exceeds the forecasted amount for such year and may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $203,451 in 1996, $196,956 in 1997 and $169,162 for
the first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Park Towne Place Associates Limited Partnership is a Delaware limited
partnership which raised net proceeds of approximately $38,000,000 in 1986
through a private offering. The promoter for the private offering of your
partnership was Winthrop Securities Co., Inc. Insignia acquired your partnership
in November 1997. AIMCO acquired Insignia in October, 1998. There are currently
a total of 446 limited partners of your partnership and a total of 380 units of
your partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
single apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on October 18, 1985 for the purpose of owning
and operating a single apartment property located in Philadelphia, Pennsylvania,
known as "Park Towne Apartments." Your partnership's property consists of 973
apartment units. The total rentable square footage of your partnership's
property is 788,841 square feet. The average annual rent per apartment unit is
approximately $10,245.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $203,451, $196,956 and $169,162, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2035
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates will not incur any liability, responsibility or accountability
for damages or otherwise to your partnership or any limited partner arising out
of any acts performed or any omission by any of them if they believed in good
faith that such act or omission was in the best interests of your partnership
and such course of conduct did not constitute negligence or misconduct on the
part of the general partner. As a result, unitholders might have a more limited
right of action in certain circumstances than they would have in the absence of
such a provision in your partnership's agreement of limited partnership. The
general partner of your partnership is owned by AIMCO. See "Conflicts of
Interest".
 
     Your partnership will, to the extent permitted by law, indemnify and save
harmless the general partner and its affiliates against and from any loss,
liability, cost or expenses (including reasonable attorneys' fees) or damage
sustained by them in connection with your partnership provided that such loss,
liability, cost or expense or damage was not the result of negligence or
misconduct on the part of the general partners or such persons. The general
partner, its affiliates and any placing broker will not be indemnified for
liabilities arising under Federal and state securities laws unless (1) there has
been a successful adjudication on the merits of each count involving securities
law violations, (2) such claims have been dismissed with prejudice on the merits
by a court of competent jurisdiction or (3) a court of competent jurisdiction
approves settlement of the claims. In such claim for indemnification for Federal
or state securities law violation, the party seeking indemnification must place
before the court the position of the SEC and any other applicable regulatory
agency with respect o the issue of indemnification for securities law
violations. Such indemnity will be paid from, and only to the extent of,
partnership assets. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     Your partnership will not incur the cost of the portion of any insurance
which insures any party against any liability as to which such party is herein
prohibited from being indemnified.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not made a distribution within the last five years.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Park Towne Place
Associates Limited Partnership as of June 30, 1998 and for the six months ended
June 30, 1998 have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Park Towne Place Associates Limited Partnership
 
     We have audited the accompanying balance sheets of Park Towne Place
Associates Limited Partnership as of December 31, 1997 and 1996, and the related
statements of operations, partners' capital and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Park Towne Place Associates
Limited Partnership as of December 31, 1997 and 1996, and the results of its
operations, changes in partners' capital and cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Park Towne Place Associates Limited Partnership, a Delaware limited
partnership, was formed in November 1985 to acquire, renovate and operate a
four-building apartment complex known as Park Towne Place (the "Property"). The
Property consists of 969 apartment units and recreational and retail facilities
situated on approximately 8.95 acres of land. The Partnership will terminate on
December 31, 2035, or earlier upon the occurrence of certain events specified in
the partnership agreement. The general partner of the Partnership is Winthrop
Financial Associates, A Limited Partnership, a Maryland Limited Partnership
("WFA"). The initial limited partner of the Partnership was Three Winthrop
Properties, Inc.
 
     Upon admission of the Investors to the Partnership, profits, losses and
cash flow from normal operations were allocated 5% to WFA and 95% to the
investor limited partners. The partnership sold 380 limited partnership units.
 
     Effective September 30, 1996, WFA withdrew from the Partnership as the
general partner and assigned 1% of 5% interest to the new general partner, PTP
Properties, Inc. WFA retained its remaining 4% interest which was converted to a
limited partnership interest but is not considered an investor limited partner.
Profits, losses and distributions of the partnership are allocated 1% to the
general partner, 4% to WFA and 95% to the investor limited partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Rental Property
 
     Rental property is carried at cost. Depreciation is provided for in amounts
sufficient to relate the cost of depreciable assets to operations over their
estimated service lives by use of the straight-line method for financial
reporting purposes. For income tax purposes, accelerated lives and methods are
used.
 
  Deferred Costs
 
     Mortgage costs are amortized over the term of the mortgage loan using the
straight-line method.
 
  Rental Income
 
     Rental income is recognized as rents become due. Rents received in advance
are deferred until earned. All leases between the Partnership and tenants of the
property are operating leases.
 
  Income Taxes
 
     No provision has been made for federal, state or local income taxes in the
financial statements of the Partnership. The Partners are required to report on
their individual income tax returns their allocable share of income, gains,
losses, deductions and credits of the Partnership. The Partnership files its own
tax return on the accrual basis.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the Partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents.
 
NOTE B -- MORTGAGE PAYABLE
 
     On October 2, 1996, the Partnership refinanced its mortgage through GMAC
Commercial Mortgage Corporation. The new mortgage, which had an original balance
of $38,500,000, is secured by a deed of trust on the rental property and an
assignment of property leases and rents, and is guaranteed by an affiliate of
the general partner. The note bears interest at 9.125% per annum. Principal and
interest are payable by the partnership in monthly installments of $313,249
through maturity on November 1, 2006, when all outstanding principal and accrued
interest are due. Included in interest expense on the statements of operations
for the year ended December 31, 1996 is $347,957 of a prepayment penalty paid to
the old lender on refinancing its mortgage.
 
     Under agreements with the mortgage lender, the partnership is required to
make monthly escrow deposits for taxes, insurance and replacement of project
assets.
 
     The liability of the partnership under the mortgage note is limited to the
underlying value of the real estate collateral plus other amounts deposited with
the lender.
 
     Aggregate annual maturities of the mortgage payable over each of the next
five years are as follows:

NOTE C -- INVESTMENT IN LAND
 
     The land on which the property was located was previously owned by 2200
Benjamin Franklin Parkway Associates Limited Partnership (the "fee owner"), and
served as landlord under the ground lease. The general partner of the fee owner
is Nine St. James Leasing Co., whose shareholders are affiliates of the general
partner and WFA.
 
     On September 30, 1996, the partnership executed an option in their ground
lease to purchase the land for $2,000,000 from the fee owner. The partnership
financed a portion of the purchase through the refinancing as described in note
B. The remaining balance due to the fee owner at December 31, 1997 and 1996 is
$356,872. This amount is noninterest bearing and payable upon sale or
refinancing of the property.
 
NOTE D -- TAXABLE LOSS
 
     The Partnership's taxable loss for 1997 and 1996 differs from the net loss
for financial reporting purposes primarily due to differences in the recognition
of depreciation incurred by the Partnership and the recognition

     The Partnership has incurred charges by and commitments to companies
affiliated by common ownership and management with the general partner and WFA.
Related party transactions with the general partner, WFA and its affiliates
include the following:
 
          The Partnership incurred ground rent expense of $198,750 in 1996.
 
          The Partnership was managed by Winthrop Management (through October
     27, 1997), an affiliate of the general partner and WFA, which received an
     annual property management fee equal to 2% of gross operating revenues for
     the properties. Fees of $196,956 and $203,451 were charged to operations
     for 1997 and 1996, respectively.
 
          On October 28, 1997, the partnership terminated Winthrop Management as
     the managing agent and appointed Insignia Residential Group, LP
     ("Insignia") as the new management agent. (See note G to the financial
     statements.) The current management agreement provides for a property
     management fee equal to 3% of the gross operating revenues generated by the
     properties. Fees of $54,931 were charged to operations for the year ended
     December 31, 1997.
 
          Management fees include $87,774 and $101,725 in 1997 and 1996,

     credit. During 1995, the affiliate advanced an additional $240,000, and the
     Partnership repaid $68,000 of the advances. During 1996, the outstanding
     balance of $472,000 was repaid with refinancing proceeds as more fully
     described in note B.
 
          Included in other expenses is $18,982 of asset management fees and
     $8,892 of general partner reimbursement charged to operations in 1997. The
     amounts are payable to an affiliate of the general partner starting in
     November 1997. At December 31, 1997, $27,874 remains payable.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Park Towne Place Associates Limited Partnership
 
     We have audited the accompanying balance sheets of Park Towne Place
Associates Limited Partnership as of December 31, 1996 and 1995, and the related
statements of operations, partners' capital and cash flows for the years then
ended. These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Park Towne Place Associates
Limited Partnership as of December 31, 1996 and 1995, and the results of its
operations, changes in partners' capital and cash flows for the years then
ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Park Towne Place Associates Limited Partnership, a Delaware limited
partnership, was formed in November 1985 to acquire, renovate and operate a
four-building apartment complex known as Park Towne Place (the "Property"). The
Property consists of 969 apartment units and recreational and retail facilities
situated on approximately 8.95 acres of land. The Partnership will terminate on
December 31, 2035, or earlier upon the occurrence of certain events specified in
the Partnership Agreement. The general partner of the Partnership is Winthrop
Financial Associates, A Limited Partnership, a Maryland Limited Partnership
("WFA"). The initial limited partner of the Partnership was Three Winthrop
Properties, Inc.
 
     Upon admission of the Investors to the Partnership, profits, losses and
cash flow from normal operations were allocated 5% to WFA and 95% to the
Investor Limited Partners.
 
     Effective September 30, 1996, WFA withdrew from the Partnership as the
general partner and assigned 1% of 5% interest to the new general partner, PTP
Properties, Inc. WFA retained its remaining 4% interest which was converted to a
limited partnership interest but is not considered an investor limited partner.
Profits, losses and distributions of the partnership are allocated 1% to the
general partner, 4% to WFA and 95% to the investor limited partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Rental Property
 
     Rental property is carried at cost. Depreciation is provided for in amounts
sufficient to relate the cost of depreciable assets to operations over their
estimated service lives by use of the straight-line method for financial
reporting purposes. For income tax purposes, accelerated lives and methods are
used.
 
  Deferred Costs
 
     Mortgage costs are amortized over the term of the mortgage loan using the
straight line method.
 
  Rental Income
 
     Rental income is recognized as rents become due. Rents received in advance
are deferred until earned. All leases between the Partnership and tenants of the
property are operating leases.
 
  Income Taxes
 
     No provision has been made for Federal, state or local income taxes in the
financial statements of the Partnership. The Partners are required to report on
their individual income tax returns their allocable share of income, gains,
losses, deductions and credits of the Partnership. The Partnership files its own
tax return on the accrual basis.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the Partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents. The carrying amount of $1,200,015 approximates fair value because
of the short maturity of this instrument.
 
NOTE B -- MORTGAGE PAYABLE
 
     On October 2, 1996, the Partnership refinanced its mortgage through GMAC
Commercial Mortgage Corporation. The new mortgage, which had an original balance
of $38,500,000, is secured by a deed of trust on the rental property and an
assignment of property leases and rents, and is guaranteed by an affiliate of
the general partner. The note bears interest at 9.125% per annum. Principal and
interest are payable by the partnership in monthly installments of $313,249
through maturity on November 1, 2006, when all outstanding principal and accrued
interest are due. Included in interest expense on the statements of operations
for the year ended December 31, 1996 is $347,957 of a prepayment penalty paid to
the old lender on refinancing its mortgage.
 
     Under agreements with the mortgage lender, the partnership is required to
make monthly escrow deposits for taxes, insurance and replacement of project
assets.
 
     The liability of the partnership under the mortgage note is limited to the
underlying value of the real estate collateral plus other amounts deposited with
the lender.
 
     Aggregate annual maturities of the mortgage payable over each of the next
five years are as follows:

NOTE C -- INVESTMENT IN LAND
 
     The land on which the property was located was previously owned by 2200
Benjamin Franklin Parkway Associates Limited Partnership (the "Fee Owner"), and
served as landlord under the ground lease. The general partner of the Fee Owner
is Nine St. James Leasing Co., whose shareholders are affiliates of the general
partner and WFA.
 
     On September 30, 1996, the partnership executed an option in their ground
lease to purchase the land for $2,000,000 from the fee owner. The partnership
financed a portion of the purchase through the refinancing as described in Note
B. The remaining balance due to the Fee Owner at December 31, 1996 is $356,872.
This amount is noninterest bearing and payable upon sale or refinancing of the
property.
 
NOTE D -- TAXABLE LOSS
 
     The Partnership's taxable loss for 1996 and 1995 differs from the net loss
for financial reporting purposes primarily due to differences in the recognition
of depreciation incurred by the Partnership and the recognition

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2764
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2765
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Quail Run Associates, L.P. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $80.72 per unit for year ended
     December 31, 1997 (equivalent to $               on an annual basis). We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business
 
                                       S-3

     that owns and manages a large portfolio of properties, with risks that do
     not exist for your partnership. You should review the risk factors in this
     Prospectus Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
                                       S-4
<PAGE>   2773
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2776
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   2777
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   2778
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's) revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   2779
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   2780
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership has required funding from its partners. Continuation of its
     operations is dependent on additional funding from partners or from other
     sources. Your partnership faces maturity or balloon payment dates on its
     mortgage loans and must either obtain refinancing or sell its property. If
     your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your partnership without the
 
                                      S-12
<PAGE>   2781
 
     offer would deny you and your partners the benefits that your general
     partner expects to result from the offer. For example, a partner of your
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
                                      S-13

     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

on               , 1998, unless extended.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will also pay all costs and expenses of printing and mailing
this Prospectus Supplement and the legal fees and expenses in connection
therewith. We will also pay the fees of Stanger for providing the fairness
opinions for the offer. We estimate that our total costs and expenses in making
the offer (excluding the purchase price of the units payable to you and your
partners) will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   2784
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership, but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $65,350 in 1996, $69,823 in 1997 and $36,150 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Quail Run Associates, L.P. is a Delaware
limited partnership which was formed on May 28, 1984 for the purpose of owning
and operating a single apartment property located in
 
                                      S-18
<PAGE>   2787
 
Zionsville, Indiana, known as "Quail Run Apartments". In 1979, it completed a
private placement of units that raised net proceeds of approximately $3,300,000.
Quail Run Apartments consists of 166 apartment units. Your partnership has no
employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2007, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $4,038,074, payable to Marine Midland and
Bank of America, which bears interest at a rate of 7.60%. The mortgage debt is
due in October 2003. Your partnership also has a second mortgage note
outstanding of $143,487, on the same terms as the current mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2795
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   2796
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $       , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were        (equivalent to $
on an annualized basis). This is equivalent to distributions of $          per
year on the number of Tax-Deferral      % Preferred OP Units, or distributions
of $          per year on the number of Tax-Deferral Common OP Units, that you
would receive in an exchange for each of your partnership's units. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     Moody's Revision of AIMCO's Outlook of Ratings To Negative.  On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   2798
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your Partnership has required funding from its partners. Continuation of
its operations is dependent on additional funding from partners or from other
sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
                                      S-30
<PAGE>   2799
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and Tax-Deferral      % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units. Your Partnership has
       not paid any distributions on your units since the inception of your
       partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2801
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2802
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   2803
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   2804
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   2805
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

     become aware of any facts relating to your partnership, its indebtedness or

     Partnership, might affect the extension of credit by banks or other lending

     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or
 
          (c) there shall have been threatened, instituted or pending any
     action, proceeding, application or counterclaim by any Federal, state,

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   2809
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
                                      S-42
<PAGE>   2811
 
distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   2812
 
Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   2814
 
in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
                                      S-50
<PAGE>   2819
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
                                      S-51
<PAGE>   2820
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from to this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   2822
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   2823
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $       , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the year ended December 31, 1997 were $80.72. This is equivalent to
     distributions of $          per year on the number of Tax-Deferral      %
     Preferred OP Units, or distributions of $          per year on the number
     of Tax-Deferral Common OP Units, that you would receive in exchange for
     each of your partnership's units. Therefore, distributions with respect to
     the Preferred OP Units and Common OP Units that we are offering are
     expected to be        , immediately following our offer, than the
     distributions with respect to your units. This is equivalent to
     distributions of $          per year on the number of Tax-Deferral      %
     Preferred OP Units or distributions of $          per year on the number of
     Tax-Deferral Common OP Units that you would receive in an exchange for each
     of your partnership's units. See "Comparison of Ownership of Your Units and
     AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.

FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment properties although there are
other ways to value real estate. A liquidation in the future might generate a
higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Consideration....................................    $

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
                                      S-57
<PAGE>   2826
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and

performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of

 
                                      S-59
<PAGE>   2828
 
your partnership. Stanger relied upon the representations of your partnership
and AIMCO concerning, among other things, any environmental liabilities,
deferred maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net
values between the general partner, special limited partner and limited
partners of your partnership, the terms and conditions of any debt encumbering
the partnership's property, and the transaction costs and fees associated with
a sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and
good faith judgments; that no material changes have occurred in the value of
the partnership's property or other balance sheet assets and liabilities or
other information reviewed between the date of such information provided and
the date of the Fairness Opinion; that your partnership, AIMCO, and the
management of the partnership's property are not aware of any information or
facts that would cause the information supplied to Stanger to be incomplete or
misleading; that the highest and best use of the partnership's property is as
improved; and that all calculations were made in accordance with the terms of
your partnership's agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with
respect to your partnership. In addition, Stanger is entitled to reimbursement
for reasonable legal, travel and out-of-pocket expenses incurred in making the
site visits and preparing the Fairness Opinion, and is entitled to
indemnification against certain liabilities, including certain liabilities under
Federal securities laws. No portion of Stanger's fee is contingent upon
consummation of the offer or the content of Stanger's opinion. Stanger has
performed other services for AIMCO in the past, including: general financial
advisory services relating to a potential acquisition by AIMCO. However, such
acquisition was never completed and no fee was paid to Stanger.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $65,350 in 1996, $69,823 in 1997 and $36,150 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     La Colina Partners, Ltd. is a Delaware limited partnership which raised net
proceeds of approximately $3,300,000 in 1979 through a private offering. The
promoter for the private offering of your partnership was Jacques-Miller.
Insignia acquired your partnership in December 1991. AIMCO acquired Insignia in
October, 1998. There are currently a total of 32 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 28, 1984 for the purpose of owning and
operating a single apartment property located in Zionsville, Indiana, known as
"Quail Run Apartments." Your partnership's property consists of 166 apartment
units. The total rentable square footage of your partnership's property is
197,120 square feet. The average annual rent per apartment unit is approximately
$8,021.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $65,350, $69,823 and $36,150, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2007
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a first mortgage note
outstanding of $4,038,074, payable to Marine Midland and Bank of America, which
bears interest at a rate of 7.60%. The mortgage debt is due in October 2003.
There is a second mortgage with an outstanding balance of $143,487 as of June
30, 1998, and with substantially similar terms as the first. Your partnership's
agreement of limited partnership also allows the general partner of your
partnership to lend funds to your partnership. Currently, the general partner of
your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

     Interest Income
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $97,503 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
     The partnership had debt that has matured in June 1997 and due to Jacques
Miller Income Fund II totalling $454,522. This amount remains unpaid and the
partnership may either refinance or negotiate the purchase of this note.
However, there can be no assurance that such refinancing or negotiation will
occur.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership is not
liable to your partnership or any limited partner for any acts or failures to do
any act performed by it of them in the absence of their willful malfeasance or
gross negligence. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership's agreement of limited partnership does not provide for
indemnification of the general partner by your partnership for any acts or
omissions performed by them.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

     Skadden, Arps, Slate, Meagher & Flom LLP will deliver an opinion to the
effect that the Common OP Units and the Preferred OP Units offered by this
Prospectus Supplement will be validly issued, fully paid and nonassessable.
Skadden, Arps, Slate, Meagher & Flom LLP will deliver an opinion as to the
status of AIMCO as a REIT. Skadden, Arps, Slate, Meagher & Flom LLP has
previously performed certain legal services on behalf of AIMCO and the AIMCO
Operating Partnership and their affiliates.
 
     The opinion of Skadden, Arps, Slate, Meagher & Flom LLP is not attached to
this Prospectus Supplement. However, upon receipt of a written request by a
unitholder or representative so designated in writing, a copy of such opinion
will be sent by the Information Agent.
 
                                    EXPERTS
 
     The financial statements of Quail Run Associates, L.P. at December 31,
1997, 1996 and 1995 and for the years then ended, appearing in this Prospectus
Supplement have been audited by KPMG Peat Marwick LLP, independent auditors, as
set forth in their reports thereon appearing elsewhere herein, and are included
in reliance upon such reports given upon the authority of such firm as experts
in accounting and auditing.
 
     The report dated February 24, 1998 refers to the fact that the partnership
is not generating sufficient cash flow to meet its maturing debt service
requirements, which raises substantial doubt about its ability to continue as a
going concern. The financial statements do not include any adjustments that
might result from the outcome from this uncertainty.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Quail Run Associates, LP
of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Quail Run Associates, LP:
 
     We have audited the accompanying balance sheets of Quail Run Associates, LP
as of December 31, 1997 and 1996, and the related statements of operations and
changes in partners' deficit and cash flows for the years then ended. These
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Quail Run Associates, LP as
of December 31, 1997 and 1996, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.
 
     The accompanying financial statements have been prepared assuming that the
Partnership will continue as a going concern. As discussed in Note E to the
financial statements, the Partnership is not generating sufficient cash flows to
meet its maturing debt service requirements, which raises substantial doubt
about its ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note E. The accompanying financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Quail Run Associates, LP (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated May 31, 1984.
The Partnership owns and operates a 166 unit apartment complex, Quail Run
Apartments, in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings and personal property are depreciated over a 5 to 25 year
period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996, include unamortized deferred
loan costs of $73,189 and $88,178, respectively, which are amortized over the
term of the related borrowing. They are shown net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

amount due to Jacques-Miller Income Fund II. The negotiations are expected to be
completed during the second quarter of 1998; however, there is no assurance that
the negotiations will be successful.

     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid principal
balance at the time of prepayment or the present value of the excess of interest
which would be incurred at the stated rate under the notes over the interest
which would be incurred at the Treasury constant maturity for U.S. Government
obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership has no administrative or management employees and is
dependent on the Managing General Partner and its affiliates for the management
and administration of all partnership activities. The Partnership is obligated
to pay a property management fee equal to 5% of gross monthly collections. In
addition to the management fee, the partnership agreement provides for payments
to affiliates of a partnership administration fee and reimbursement of certain
expenses incurred by affiliates on behalf of the Partnership.
 
     Transactions with the Managing General Partner and its affiliates, in
addition to those disclosed in Note C, are as follows:

NOTE E -- GOING CONCERN
 
     The Partnership is not generating sufficient cash flows to meet its
maturing debt service requirements, which raises substantial doubt about its
ability to continue as a going concern. The Managing General Partner is
attempting to refinance the existing debt. The Managing General Partner believes
that it will be successful, however there can be no assurance that refinancing
will be obtained. The financial statements have been prepared assuming that the
Partnership will continue as a going concern and do not include any adjustments
that might result from the outcome of this uncertainty.

General Partners
Quail Run, Limited:
 
     We have audited the accompanying balance sheets of Quail Run Associates, LP
as of December 31, 1996 and 1995, and the related statements of operations and
changes in partners' deficit and cash flows for the years then ended. These
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Quail Run, Limited as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Quail Run Associates, LP (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated May 31, 1984.
The Partnership owns and operates a 166 unit apartment complex, Quail Run
Apartments in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings and personal property are depreciated over a 5 to 25 year
period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 consist of deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or
     Preferred OP Units of the Purchaser, or a combination of any of such forms
of consideration. The limited partners of the Partnership (the "Limited
Partners") will have the choice to maintain their current interest in the
Partnership or exchange their Units for any or a combination of such forms of
consideration. The amount of cash, Common OP Units or Preferred OP Units offered
per Unit is referred to herein as the "Offer Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
                                       A-1
<PAGE>   2869
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2870
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Ravenworth Associates Limited Partnership. For each unit that you tender,
     you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2875
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2876
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the interests paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principle advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership has never made a distribution. We will pay fixed quarterly
     distributions of $               per unit on the Tax-Deferral   % Preferred
     OP Units before any distributions are paid to holders of Tax-Deferral
     Common OP Units. We pay quarterly distributions on the Tax-Deferral Common
     OP Units based on our funds from operations for that quarter. For the six
     months ended June 30, 1998, we paid distributions of $1.125 on each of the
     Tax-Deferral Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   2877
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.

<PAGE>   2878
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2881
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   2882
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   2883
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   2884
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, or President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   2885
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 0% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding the limited partners holding at least a majority
     of the units of your partnership. In the absence of such consent, your only
     option for liquidation of your investment would be to sell your units in a
     private transaction. Any such sale could be at a very substantial discount
     from your pro rata share of the fair market value of your partnership's
     property and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   2886
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than Your Partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

<PAGE>   2888
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are

Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much
 
                                      S-16
<PAGE>   2890
 
     of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, unlike the general partner of the AIMCO Operating Partnership,
the general partner of your partnership is entitled to compensation for its
services as general partner.

COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity. The property manager received management fees of
$110,013 in 1996, $119,689 in 1997 and $58,703 for the first six months of 1998.
We have no current intention of changing the fee structure for your property
manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Ravenworth Associates Limited
Partnership is a Massachusetts limited partnership which was formed on June 21,
1983 for the purpose of owning and operating a single apartment property located
in Annandale, Virginia, known as "Ravenworth Towers Apartments". In 1993, it
completed a private placement of units that raised net proceeds of approximately
$3,648,000. Ravenworth Towers Apartments consists of 219 apartment units. Your
partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors.

     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2013, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $9,799,800, payable to FNMA, which bears
interest at a rate of 8.38%. The mortgage debt is due in November 2003. Your
partnership also has a second mortgage note outstanding of $2,996,882, on the
same terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner has no loans outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned

     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   2900
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   2901
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions of $     are
expected with respect to the Preferred OP Units, and current annualized
distributions with respect to the Common OP Units are $2.25. Your partnership
has not made a distribution in the last five years. See "Comparison of Ownership
of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be
 
                                      S-28
<PAGE>   2902
 
issued by AIMCO, and confirmed its previous ratings related to AIMCO's preferred
stock and debt in its shelf registration statement. Moody's indicated that its
rating action continues to reflect AIMCO's increasing leveraged profile,
including high levels of secured debt and preferred stock, limited financial
flexibility and integration risks resulting from the merger with Insignia.
Moody's also noted AIMCO's high level of encumbered properties and material
investments in loans to highly leveraged partnerships in which AIMCO owns a
general partnership interest. At the same time, Moody's confirmed its existing
rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and
 
                                      S-29
<PAGE>   2903
 
your partners. In the opinion of the general partner of your partnership, the
present time may not be the most desirable time to sell the real estate assets
of your partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties may improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there have never been
any distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership. However, one class of outstanding Partnership Preferred
       Units has prior distribution rights and the
 
                                      S-30
<PAGE>   2904
 
Tax-Deferral   % Preferred OP Units rank equal to six other outstanding classes
of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your units
       since the inception of your partnership. Historically the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   2906
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   2907
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   2908
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   2909
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of considerations being offered, or increasing or decreasing the
percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   2910
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

units tendered, and may terminate or amend the offer if at any time from or
after           , 1998 and at or before the time of acceptance for payment of
any such units (whether or not any units have theretofore been accepted for
payment and paid for) pursuant to the offer, any of the following shall occur:

     including any fire, flood, natural disaster, casualty loss, or act of God
     that, which change, in the sole judgment of the AIMCO Operating
     Partnership, is or may be materially adverse to your partnership or the
     value of your units to the AIMCO Operating Partnership, or the AIMCO
     Operating Partnership shall have become aware of any facts relating to your
     partnership, its indebtedness or its operations which, in the sole judgment

     Operating Partnership, might affect the extension of credit by banks or
     other lending institutions, or (viii) in the case of any of the foregoing
     existing at the time of the commencement of the offer, in the sole judgment
     of the AIMCO Operating Partnership, a material acceleration or worsening
     thereof; or
 
          (c) there shall have been threatened, instituted or pending any
     action, proceeding, application or counterclaim by any Federal, state,
     local or foreign government, governmental authority or governmental agency,

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   2914
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   2915
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-42
<PAGE>   2916
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-43
<PAGE>   2917
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   2919
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   2924
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   2925
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.

     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   2927
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   2928
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions of $     are expected with
     respect to the Preferred OP Units, and current annualized distributions
     with respect to the Common OP Units are $2.25. Your partnership has not
     made a distribution in the last five years. See "Comparison of Ownership of
     Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment properties although there are
other ways to value real estate. A liquidation in the future might generate a
higher price for holders of units.
 
                                      S-55
<PAGE>   2929
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   2933
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in its capacity as general partner. The property manager received
management fees of $110,013 in 1996 and $119,689 in 1997 and $58,703 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Ravenworth Associates Limited Partnership is a Massachusetts limited
partnership which raised net proceeds of approximately $3,648,000 in 1993
through a private offering. The promoter for the private offering of your
partnership was Winthrop Financial Co., Inc.. Insignia acquired your partnership
in November 1997. AIMCO acquired Insignia in October, 1998. There are currently
a total of 59 limited partners of your partnership and a total of 50 units of
your partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
single apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on June 21, 1983 for the purpose of owning and
operating a single apartment property located in Annandale, Virginia, known as
"Ravenworth Towers Apartments." Your partnership's property consists of 219
apartment units. There are 144 one-bedroom apartments and 75 two-bedroom
apartments. The total rentable square footage of your partnership's property is
175,200 square feet. The average annual rent per apartment unit is approximately
$9,943.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $110,013, $96,770, and $58,703, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2013
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $9,799,800, payable to FNMA, which bears interest at a rate of
8.38%. The mortgage debt is due in November 2003. Your partnership also has a
second mortgage note outstanding of $2,996,882, on the same terms as the current
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership and
their affiliates will not incur any liability, responsibility or accountability
for damages or otherwise to your partnership or any limited partner for any acts
or omissions performed or omitted by any of them in good faith on behalf of your
partnership and in a manner reasonably believed by them to be within the scope
of the
 
                                      S-75
<PAGE>   2949
 
     authority granted to them by your partnership's agreement of limited
partnership and in the best interests of your partnership if they are not guilty
of negligence or willful misconduct with respect to such acts of omissions. As a
result, unitholders might have a more limited right of action in certain
circumstances than they would have in the absence of such a provision in your
partnership's agreement of limited partnership. The general partner of your
partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will indemnify the general partners for any act performed
by them within the scope of the authority conferred upon them by your
partnership's agreement of limited partnership; provided, however, that such
indemnity will be payable only if the general partners acted in good faith and
in a manner they reasonably believed to be in, or not opposed to, the best
interests of your partnership and the partners and has no reasonable grounds to
believe that their conduct was negligent or unlawful. If a general partner is
liable for negligence of misconduct in the performance of its duty to your
partnership, it will not be indemnified unless, and only to the extent that, the
court in which such action or suit was brought determines that in view of all
the circumstances of the case, despite the adjudication of liability, the
general partner is fairly and reasonably entitled to indemnity for those
expenses which the court deems proper. Any indemnity will be paid from, and only
to the extent of, partnership assets. As part of its assumption of liabilities
in the consolidation, AIMCO will indemnify the general partner of your
partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

     Your partnership has made no distributions.
 
     The following table sets forth the distributions paid per unit in the

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Ravenworth Associates
Limited Partnership as of June 30, 1998 and for the six months ended June 30,
1998 have been prepared in accordance with the accounting basis used for Federal
income tax reporting. Accordingly, they do not include all the information and
footnotes required by the accounting basis used for Federal income tax reporting
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Ravensworth Associates Limited Partnership
 
     We have audited the accompanying balance sheets of Ravensworth Associates
Limited Partnership as of December 31, 1997 and 1996, and the related statements
of revenue and expenses, changes in partners' deficit and cash flows for the
years then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     As described in Note 2, the Partnership's policy is to prepare its
financial statements on the accounting basis used for income tax purposes.
Accordingly, the accompanying financial statements are not intended to present
financial position and results of operations in conformity with generally
accepted accounting principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Ravensworth Associates
Limited Partnership as of December 31, 1997 and 1996 and the results of its
operations and its cash flows for the years then ended, in conformity with the
basis of accounting described in Note 2.

                           DECEMBER 31, 1997 AND 1996
 
1.  ORGANIZATION
 
     Ravensworth Associates Limited Partnership (the "Partnership"), a
Massachusetts limited partnership, was organized on July 5, 1983 to acquire, own
and operate a nine-story residential apartment complex known as Ravensworth
Towers Apartments (the "Property"), located in Annandale, Virginia. The Property
consists of approximately six acres of land, 219 apartment units, 350 outdoor
parking spaces, an outdoor swimming pool and other recreational facilities.
 
     Stephen A. Goldberg ("Goldberg") and Winthrop Northeast Properties, Inc.
("Winthrop Northeast") are the General Partners. Joseph R. Schuble is the Class
B Limited Partner and Linnaeus-Phoenix Associates Limited Partnership
("Linnaeus") is the Class C Limited Partner. The Partnership received $400 of
capital contributions from the General Partners and the Class B and C Limited
Partners. Investor Limited Partners purchased 50 Units of Limited Partnership
Interest at $72,960 per Unit.
 
     Pursuant to approval of a Recapitalization Proposal by a majority of Class
A Limited Partners, Class D Limited Partners were admitted into the Partnership
on November 30, 1987. The capital contributions of the Class D Limited Partners
totaled $750,000 (of which $705,000 was contributed by Winthrop Northeast) and
is being held in a working capital account. The terms of the Class D Units
include a special allocation of the first $750,000 of tax losses, a 40% interest
in profits and losses thereafter and a 40% interest in cash flow and sale or
refinancing proceeds.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with the accounting method used for Federal income tax
purposes.
 
  Depreciation
 
     Depreciation is calculated using the accelerated cost recovery system over
15, 19 and 27.5 year recovery periods for real property, and a 5 or 7 year
recovery period for equipment.
 
  Amortization
 
     Loan costs are being amortized on a straight-line basis over the term of
the loan.
 
  Income Taxes
 
     No provision for income taxes is reflected in the accompanying financial
statements of the Partnership. Partners are required to report on their
individual tax return their allocable share of income, gains, losses, deductions
and credits of the Partnership.
 
     The Partnership's tax returns are subject to examination by Federal and
state taxing authorities. Because many types of transactions are subject to
varying interpretations under Federal and state income tax laws and regulations,
an examination of the Partnership's tax returns may lead to adjustments to the
amounts reported in the accompanying financial statements.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with the income tax
basis of accounting requires management to make estimates and assumptions that
affect the reported amount of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts

                   RAVENSWORTH ASSOCIATES LIMITED PARTNERSHIP
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
of revenue and expenses during the reporting period. Accordingly, actual results
could differ from those estimates.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid instruments with an initial
maturity of six months or less to be cash equivalents for purposes of the
statement of cash flows.
 
  Accounts Receivable
 
     At December 31, 1997, management considers all accounts receivable to be
collectible.
 
3.  CONCENTRATION OF RISK
 
     During the year, the Partnership, at times, maintained cash balances in
excess of the Federally insured maximum of $100,000. Management does not
consider the risk to be significant.
 
4.  BUILDING, IMPROVEMENTS AND EQUIPMENT

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Ravensworth Associates Limited Partnership
 
     We have audited the accompanying balance sheets of Ravensworth Associates
Limited Partnership as of December 31, 1996 and 1995, and the related statements
of revenue and expenses, changes in partners' deficit and cash flows for the
years then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     As described in Note 2, the Partnership's policy is to prepare its
financial statements on the accounting basis used for income tax purposes.
Accordingly, the accompanying financial statements are not intended to present
financial position and results of operations in conformity with generally
accepted accounting principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Ravensworth Associates
Limited Partnership as of December 31, 1996 and 1995 and the results of its
operations and its cash flows for the years then ended, in conformity with the
basis of accounting described in Note 2.

  Income Taxes
 
     No provision for income taxes is reflected in the accompanying financial
statements of the Partnership. Partners are required to report on their
individual tax return their allocable share of income, gains, losses, deductions
and credits of the Partnership.
 
     The Partnership's tax returns are subject to examination by Federal and
state taxing authorities. Because many types of transactions are subject to
varying interpretations under Federal and state income tax laws and regulations,
an examination of the Partnership's tax returns may lead to adjustments to the
amounts reported in the accompanying financial statements.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer consideration per Unit of $       in cash, or
       Common OP Units of the Purchaser, or        Preferred OP Units of the
Purchaser, or a combination of any of such forms of consideration. The limited
partners of the Partnership (the "Limited Partners") will have the choice to
maintain their current interest in the Partnership or exchange their Units for
any or a combination of such forms of consideration. The amount of cash, Common
OP Units or Preferred OP Units offered per Unit is referred to herein as the
"Offer Consideration."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Consideration is fair to the Limited
Partners of the Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   2976
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   2977
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Consideration or the method of determining the Offer Consideration in connection
with the Offer; (ii) make any recommendation to the Partnership or its partners
with respect to whether to accept or reject the Offer or whether to accept the
cash, Preferred OP Units or Common OP Units if the Offer is accepted; (iii)
solicit any third party indications of interest in acquiring the assets of the
Partnership or all or any part of the Partnership; or (iv) express any opinion
as to (a) the tax consequences of the proposed Offer to the Limited Partners,
(b) the terms of the Partnership Agreement or of any agreements or contracts
between the Partnership and the Company, (c) the Company's business decision to
effect the Offer or alternatives to the Offer, (d) the amount of expenses
relating to the Offer or their allocation between the Company and the
Partnership or tendering Limited Partners; (e) the relative value of the cash,
Preferred OP Units or Common OP Units to be issued in connection with the Offer;
and (f) any adjustments made to determine the Offer consideration and the net
amounts distributable to the Limited Partners, including but not limited to,
balance sheet adjustments to reflect the Partnership's estimate of the value of
current net working capital balances, reserve accounts, and liabilities, and
adjustments to the Offer Consideration for distributions made by the Partnership
subsequent to the date of the initial Offer. We are not expressing any opinion
as to the fairness of any terms of the Offer other than the Offer Consideration
for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Consideration is fair to the Limited Partners of
the Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Rivercreek Apartments Limited Partnership. For each unit that you tender,
     you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972, total debt of $1,626 and stockholders' equity
     of $1,844.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   2982
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   2983
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering the units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $12,166.66 per unit for the six
     months ended June 30, 1998 (equivalent to $24,333.32 on an annual basis).
     We will pay fixed quarterly distributions of $               per unit on
     the Tax-Deferral   % Preferred OP Units before any distributions are paid
     to holders of Tax-Deferral Common OP Units. We pay quarterly distributions
     on the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

<PAGE>   2984
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   2985
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   2988
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   2989
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   2990
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   2991
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   2992
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 0% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   2993
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                      S-14
<PAGE>   2995
 
     to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your
 
                                      S-15
<PAGE>   2996
 
     partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a
widely-accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
                                      S-16
<PAGE>   2997
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.

CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $57,000 in 1996, $56,000 in 1997 and $28,585 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Rivercreek Apartments Limited
Partnership is a South Carolina limited partnership which was formed on December
26, 1979 for the purpose of owning and operating a single apartment property
located in Augusta, Georgia, known as "Rivercreek Apartments". In 1979, it
completed a private placement of units that raised net proceeds of approximately
$1,560,000. Rivercreek Apartments consists of 234 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2019, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
                                      S-18
<PAGE>   2999
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,784,998, payable to MBL Life Assurance
Corp., which bears interest at a rate of 7.25%. Your partnership's agreement of
limited partnership also allows your general partner to lend funds to your
partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer price from a financial
point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3007
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   3008
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $12,166.66 per unit
(equivalent to $24,333.32 on an annualized basis). This is equivalent to
distributions of $          per year on the number of Tax-Deferral      %
Preferred OP Units, or distributions of $          per year on the number of
Tax-Deferral Common OP Units, that you would receive in an exchange for each of
your partnership's units. Therefore, distributions with respect to the Preferred
OP Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service ("Moody's") revised its outlook for the ratings
of AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of the more difficult general capital
market conditions. Moody's noted that AIMCO's access to the public markets may
prove challenging in light of the volatility in both the equity and capital
markets for REITs. Moody's assigned a "ba3" rating to the Class I Preferred
Stock proposed to be issued by AIMCO, and confirmed its previous ratings related
to AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   3010
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   3011
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   3013
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   3014
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   3015
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   3016
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   3018
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     or other lending institutions, or (viii) in the case of any of the

<PAGE>   3020
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   3021
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

<PAGE>   3022
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   3023
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   3024
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   3026
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   3031
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   3032
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   3034
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   3035
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June, 1998 were $12,166.66 (equivalent to $24,333.32
     on an annualized basis). This is equivalent to distributions of $
     per year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units, that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   3036
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
                                      S-57
<PAGE>   3038
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF MATERIALS CONSIDERED
 
     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and
through June 30, 1998; (v) reviewed operating budgets for your partnership's
property for 1998, as prepared by your partnership; (vi) reviewed information

                                      S-58
<PAGE>   3039
 
     performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59
<PAGE>   3040
 
     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity which received management
fees of 57,000 in 1996, 56,000 in 1997 and 28,585 for the first six months of
1998. The AIMCO Operating Partnership has no current intention of changing the
fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Rivercreek Apartments Limited Partnership is a South Carolina limited
partnership which raised net proceeds of approximately $1,560,000 in 1979
through a private offering. The promoter for the private offering of your
partnership was U.S. Shelter Corporation and N. Barton Tuck, Jr. Insignia
acquired your partnership in December 1990. AIMCO acquired Insignia in October,
1998. There are currently a total of 31 limited partners of your partnership and
a total of 30 units of your partnership outstanding. Your partnership is in the
business of owning and managing residential housing. Currently, your partnership
owns and manages the single apartment property described below. Your partnership
has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on December 26, 1979 for the purpose of owning
and operating a single apartment property located in Augusta, Georgia, known as
"Rivercreek Apartments." Your partnership's property consists of 234 apartment
units. There are 112 one-bedroom apartments and 122 two-bedroom apartments. The
total rentable square footage of your partnership's property is 160,804 square
feet. Your partnership's property had an average occupancy rate of approximately
91.52% in 1996 and 91.52% in 1997. The average annual rent per apartment unit is
approximately $4,701.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $57,000, $56,000 and $28,585, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2019
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of

outstanding of $3,784,998, payable to MBL Life Assurance Corp., which bears
interest at a rate of 7.25%. The mortgage debt is due in January 2008. [SECOND
MORTGAGE] Your partnership's agreement of limited partnership also allows the
general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS

ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not

costs, totaled $114,611 for the six months ended June 30, 1998, compared to
$160,782 for the six months ended June 30, 1997, a decrease of $46,171, or

costs, totaled $324,000 for the year ended December 31, 1996, compared to
$326,047 for the year ended December 31, 1995, a decrease of $2,047, or 0.63%.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $357,603 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership and
their affiliates are not liable to your partnership or the limited partners for
any loss or damage resulting from any act or omission performed or omitted in
good faith, pursuant to the authority granted to them to promote the interests
of your partnership. Moreover, the general partners are not liable to your
partnership or the limited partners because any taxing authorities disallow or
adjust any deductions or credits in your partnership income tax returns. As a
result, unitholders might have a more limited right of action in certain
circumstances than they would have in the absence of such a provision in your
partnership's agreement of limited partnership. The general partner of your
partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will also indemnify the general partners and their
affiliates against any loss, expense, liability, action or damage resulting from
any act or omission performed or omitted in good faith, pursuant to the
authority granted to them to promote the interests of your partnership if any
court determines that such conduct merits indemnity.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS

     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions (i.e., excluding transactions
believed to be between related parties, family members or the same beneficial
owner) was as follows:

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $

such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Rivercreek Apartments as
of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with the accounting basis for Federal income tax
reporting. Accordingly, they do not include all the information and footnotes
required by the accounting basis for Federal income tax reporting for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

The Partners
Rivercreek Apartments Limited Partnership
 
     We have audited the accompanying balance sheet of Rivercreek Apartments
Limited Partnership as of December 31, 1997, and the related statements of
operations, partners' deficit and cash flows for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Rivercreek Apartments
Limited Partnership at December 31, 1997, and the results of its operations and
cash flows for the year then ended, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercreek Apartments Limited Partnership (the "Partnership") was organized
as a limited partnership under the laws of the State of South Carolina pursuant
to a Certificate and Agreement of Limited Partnership dated December 27, 1979,
and extending to December 31, 2019, unless terminated sooner. Thirty-one units
of limited partnership interests, an individual general partnership interest,
and a corporate general partnership interest were issued. The Partnership owns
and operates a 224-unit apartment complex, Rivercreek Apartments, in Augusta,
Georgia.
 
  Investment Property
 
     The investment property is stated at cost. Acquisition fees are capitalized
as a cost of real estate. The Partnership records impairment losses on
long-lived assets used in operations when events and circumstances indicate that
the assets might be impaired and the undiscounted cash flows estimated to be
generated by those assets are less than the carrying amounts of those assets. No
adjustments for impairment of value were necessary for the year ended December
31, 1997.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Risks and Uncertainties
 
     The real estate business is highly competitive. The Partnership's real
property investments are subject to competition from similar types of properties
in the vicinities in which they are located and the Partnership is not a
significant factor in its industry. In addition, various limited partnerships
have been formed by related parties to engage in business which may be
competitive with the Partnership.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Fair Value
 
     The Partnership believes that the carrying amount of its financial
instruments (except for long term debt) approximates their fair value due to the
short term maturity of these instruments. The fair value of the Partnership's
long term debt, after discounting the scheduled loan payments at an estimated
borrowing rate currently available to the Partnership, approximates its carrying
value.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits." Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit and the tenant is current on its rental payments.

NOTE C -- MORTGAGE NOTE PAYABLE
 
     In December 1997, the Partnership refinanced the mortgage encumbering the
investment property. The total indebtedness refinanced was approximately
$3,004,000. The new indebtedness of $3,800,000 carries a stated rate of 7.25%
and is amortized over thirty years with a balloon payment of $2,469,000 due on
January 1, 2008. A Repair Escrow of $25,000 was established with the refinancing
proceeds for certain repairs identified at the time of the refinancing. In
addition, the new note requires a monthly deposit of approximately $4,000 for a
replacement reserve. The Partnership incurred approximately $101,000 in loan
costs associated with the refinancing. The Partnership recognized an
extraordinary loss of approximately $104,000 resulting from prepayment penalties
incurred and the write-off of unamortized loan costs.
 
     The mortgage note is payable in monthly installments of approximately
$26,000. The mortgage note is nonrecourse and is collateralized by all apartment
property and related tenant leases. The mortgage note requires prepayment
penalties if repaid prior to maturity.
 
     Principal maturities of the mortgage note payable at December 31, 1997 are
as follows (in thousands):

     Additionally, the Partnership paid approximately $15,000 to affiliates of
Insignia for reimbursements of costs related to the refinancing of Rivercreek in
December 1997. These costs were capitalized as loan costs and are being
amortized over the term of the loan.
 
     For the period of January 1, 1997, to August 31, 1997, the Partnership
insured its property under a master policy through an agency and insurer
unaffiliated with the Managing General Partner. An affiliate of the Managing
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the master policy. The agent assumed the financial obligations to the
affiliate of the Managing General Partner who received payments on these
obligations from the agent. The amount of the Partnership's insurance premiums
that accrued to the benefit of the affiliate of the Managing General Partner by
virtue of the agent's obligations was not significant.
 
     Insignia entered into an Agreement and Plan of Merger, dated as of May 26,
1998, (as subsequently amended and restated, the "Merger Agreement") with
Apartment Investment and Management Company ("AIMCO"), pursuant to which
Insignia will merge its national residential property management operations and
its controlling interest in Insignia Properties Trust with and into AIMCO, with
AIMCO as the survivor. Consummation of the Merger, which is anticipated to occur
in the third quarter of 1998, is subject to certain conditions, including the
approval of the stockholders of Insignia (but not the approval of the
stockholders of AIMCO). If the closing occurs, AIMCO will then control the
General Partner of the Partnership.

     Taxable income or loss of the Partnership is reported in the income tax

NOTE F -- YEAR 2000 (UNAUDITED)
 
     The Partnership is dependent upon the General Partner and Insignia for
management and administrative services. Insignia has completed an assessment and
will have to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter (the "Year 2000 Issue"). The project is estimated to be completed not
later than December 31, 1998, which is prior to any anticipated impact on its
operating systems. The General Partner believes that with modifications to
existing software and conversions to new software, the Year 2000 Issue will not
pose significant operational problems for its computer systems. However, if such
modifications and conversions are not made, or are not completed timely, the
Year 2000 Issue could have a material impact on the operations of the
Partnership.

NOTE G -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Rivercreek Apartments Limited Partnership
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Rivercreek Apartments Limited
Partnership as of December 31, 1997, and the related statement of revenues,
expenses and changes in partners' deficit -- Federal income tax basis for the
year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As described in Note A, these financial statements have been prepared on
the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Rivercreek Apartments Limited Partnership at December 31, 1997, and its
revenues, expenses and changes in partners' deficit for the year then ended, on
the basis of accounting described in Note A.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercreek Apartments Limited Partnership (the "Partnership") was organized
as a limited partnership under the laws of the State of South Carolina pursuant
to a Certificate and Agreement of Limited Partnership dated December 27, 1979,
and extending to December 31, 2019, unless terminated sooner. The Partnership
owns and operates a 224-unit apartment complex, Rivercreek Apartments, in
Augusta, Georgia.
 
  Basis of Accounting
 
     The financial statements are prepared on the accrual basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The tax basis used differs
from GAAP primarily because, on the tax basis, (1) certain rental income
received in advance is recorded as income in the year received rather than in
the year earned, (2) buildings and related personal property acquired after
December 31, 1980 are depreciated using the asset lives specified under the
accelerated cost recovery system ("ACRS") or modified ACRS instead of over the
estimated lives of the assets and (3) amortization of certain deferred fees is
not allowed.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Buildings and related personal property acquired prior to January 1, 1981
are depreciated using straight-line and accelerated methods over estimated lives
of 3 to 33 years; additions subsequent to December 31, 1980 are depreciated
using the lives specified under ACRS. Under ACRS, depreciation is based on
accelerated methods (1) for real property, over 15 years for additions prior to
March 16, 1984, 18 years for additions after March 15, 1984 and before May 9,
1985, and 19 years for additions after May 8, 1985 and before January 1, 1987,
and (2) for personal property, over 5 years for additions prior to January 1,
1987. As a result of the Tax Reform Act of 1986, for additions after December
31, 1986, the modified ACRS method is used (1) for real property additions over
27 1/2 years and (2) for personal property additions over 7 years.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits." Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit and the tenant is current on its rental payments.

  Amortization
 
     Loan costs are being amortized using the straight-line method over the life
of the loan (ten years).
 
  Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital have
been capitalized and represent a deferred charge deductible upon termination of
the Partnership.
 
  Income Taxes
 
     No provision has been made for income taxes in the accompanying financial
statements since such taxes, if any, are the liability of the individual
partners.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.

NOTE C -- MORTGAGE NOTE PAYABLE
 
     In December 1997, the Partnership refinanced the mortgage encumbering the
investment property. The total indebtedness refinanced was approximately
$3,004,000. The new indebtedness of $3,800,000 carries a stated rate of 7.25%
and is amortized over thirty years with a balloon payment due on January 1,
2008. A Repair Escrow of $25,000 was established with the refinancing proceeds
for certain repairs identified at the time of the refinancing. In addition, the
new note requires a monthly deposit of approximately $4,000 for a replacement
reserve. The Partnership incurred approximately $102,000 in loan costs
associated with the refinancing. The Partnership recognized a loss of
approximately $104,000 resulting from prepayment penalties incurred and the
write-off of unamortized loan costs.
 
     The mortgage note is payable in monthly installments of approximately
$26,000. The mortgage note is nonrecourse and is collateralized by all apartment
property and related tenant leases. The mortgage note requires prepayment
penalties if repaid prior to maturity.

NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     Affiliates of Insignia Financial Group, Inc. ("Insignia") own the
controlling ownership interest in the Partnership's Managing General Partner,
with certain affiliates of Insignia providing property management and asset
management services to the Partnership.
 
     The following payments were made to Insignia and its affiliates in 1997 (in
thousands):
 
<TABLE>

Property management fees...............................  $56
General partner reimbursements.........................    9
</TABLE>
 
     Additionally, the Partnership paid approximately $15,000 to affiliates of
Insignia for reimbursements of costs related to the refinancing of Rivercreek in
December 1997. These costs were capitalized as loan costs and are being
amortized over the term of the loan.
 
     For the period of January 1, 1997, to August 31, 1997, the Partnership
insured its property under a master policy through an agency and insurer
unaffiliated with the Managing General Partner. An affiliate of the Managing
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the master policy. The agent assumed the financial obligations to the
affiliate of the Managing General Partner who received payments on these
obligations from the agent. The amount of the Partnership's insurance premiums
that accrued to the benefit of the affiliate of the Managing General Partner by
virtue of the agent's obligations was not significant.
 
NOTE E EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Rivercreek Apartments Limited Partnership
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Rivercreek Apartments Limited
Partnership as of December 31, 1996, and the related statement of revenues,
expenses and changes in partners' deficit -- Federal income tax basis for the
year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As described in Note A, these financial statements have been prepared on
the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Rivercreek Apartments Limited Partnership as of December 31, 1996, and its
revenues, expenses and changes in partners' deficit for the year then ended, on
the basis of accounting described in Note A.

                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercreek Apartments Limited Partnership (the "Partnership") was organized
as a limited partnership under the laws of the State of South Carolina pursuant
to a Certificate and Agreement of Limited Partnership dated December 27, 1979,
and extending to December 31, 2019, unless terminated sooner. The Partnership
owns and operates a 224-unit apartment complex, Rivercreek Apartments, in
Augusta, Georgia.
 
  Basis of Accounting
 
     The financial statements are prepared on the accrual basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The tax basis used differs
from GAAP primarily because, on the tax basis, (1) certain rental income
received in advance as recorded as income in the year received rather than in
the year earned, (2) buildings and related personal property acquired after
December 31, 1980 are depreciated using the asset lives specified under the
accelerated cost recovery system ("ACRS") or modified ACRS instead of over the
estimated lives of the assets and (3) amortization of certain deferred fees is
not allowed.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Buildings and related personal property acquired prior to January 1, 1981
are depreciated using straight-line and accelerated methods over estimated lives
of 3 to 33 years; additions subsequent to December 31, 1980 are depreciated
using the lives specified under ACRS. Under ACRS, depreciation is based on
accelerated methods (1) for real property, over 15 years for additions prior to
March 16, 1984, 18 years for additions after March 15, 1984 and before May 9,
1985, and 19 years for additions after May 8, 1985 and before January 1, 1987,
and (2) for personal property, over 5 years for additions prior to January 1,
1987. As a result of the Tax Reform Act of 1986, for additions after December
31, 1986, the modified ACRS method is used (1) for real property additions over
27 1/2 years and (2) for personal property additions over 7 years.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash and Cash Equivalents -- Unrestricted Cash
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage to the unit.

     The Partnership insures its property under a master policy through an
agency and insurer unaffiliated with the Managing General Partner. An affiliate
of the Managing General Partner acquired, in the acquisition of a business,
certain financial obligations from an insurance agency which was later acquired
by the agent who placed the current year's master policy. The current agent
assumed the financial obligations to the affiliate of the Managing General
Partner who received payment on these obligations from the agent. The amount of
the Partnership's insurance premiums accruing to the benefit of the affiliate of
the Managing General Partner by virtue of the agent's obligations is not
significant.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Rivercreek Apartments Limited Partnership
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Rivercreek Apartments Limited
Partnership as of December 31, 1995, and the related statement of revenues,
expenses and changes in partners' deficit -- Federal income tax basis for the
year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As described in Note 1, these financial statements have been prepared on
the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Rivercreek Apartments Limited Partnership as of December 31, 1995, and its
revenues, expenses and changes in partners' deficit for the year then ended, on
the basis of accounting described in Note 1.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1995
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercreek Apartments Limited Partnership (the "Partnership") was organized
as a limited partnership under the laws of the State of South Carolina pursuant
to a Certificate and Agreement of Limited Partnership dated December 27, 1979,
and extending to December 31, 2019, unless terminated sooner. The Partnership
owns and operates a 224-unit apartment complex, Rivercreek Apartments, in
Augusta, Georgia.
 
  Basis of Accounting
 
     The financial statements are prepared on the accrual basis used in the
preparation of the Partnership's Federal income tax return and do not purport to
present financial position and results of operations in accordance with
generally accepted accounting principles ("GAAP"). The tax basis used differs
from GAAP primarily because, on the tax basis, (1) certain rental income
received in advance is recorded as income in the year received rather than in
the year earned, (2) buildings and related personal property acquired after
December 31, 1980 are depreciated using the asset lives specified under the
accelerated cost recovery system ("ACRS") or modified ACRS instead of over the
estimated lives of the assets and (3) amortization of certain deferred fees is
not allowed.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Buildings and related personal property acquired prior to January 1, 1981
are depreciated using straight-line and accelerated methods over estimated lives
of 3 to 33 years; additions subsequent to December 31, 1980 are depreciated
using the lives specified under ACRS. Under ACRS, depreciation is based on
accelerated methods (1) for real property over 15 years for additions prior to
March 16, 1984, 18 years for additions after March 15, 1984 and before May 9,
1985, and 19 years for additions after May 8, 1985 and before January 1, 1987,
and (2) for personal property over 5 years for additions prior to January 1,
1987. As a result of the Tax Reform Act of 1986, for additions after December
31, 1986, the modified ACRS method is used (1) for real property additions over
27 1/2 years and (2) for personal property additions over 7 years.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Amortization
 
     Loan modification costs are being amortized using the straight-line method
over 23 years.
 
  Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital have
been capitalized and represent a deferred charge deductible upon termination of
the Partnership.
 
  Income Taxes
 
     No provision has been made for income taxes in the accompanying financial
statements since such taxes, if any, are the liability of the individual
partners.

    NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
2.  DEFERRED CHARGES
 
     Various costs incurred in connection with the purchase and refinancing of
the project are as follows:

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer

     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3094
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Rivercrest Apartments, Ltd. For each unit that you tender, you may choose
     to receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3099
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3100
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in \the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   - There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,300 per unit for the six months
     ended June 30, 1998, (equivalent to $6,600 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited.
 
     Your partnership's agreement of limited partnership prohibits any transfer
     of units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if more than 50% or
     more of the total interests in your partnership are transferred within a
     12-month period. If we acquire a significant percentage of the interest in
     your partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration of $          in cash per
     unit is fair. However, your units are not listed on any national securities
     exchange nor quoted on the NASDAQ System, and there is no established
     trading market for your units. Secondary sales activity for the units has
     been limited and sporadic. Your general partner does not monitor or
     regularly receive or maintain information regarding the prices at which
     secondary sale transactions in the units have been effectuated.
 
                                       S-4
<PAGE>   3102
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
                                       S-5
<PAGE>   3103
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3105
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.

     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units.
 
                                       S-9
<PAGE>   3107
 
We have no plans to list the OP Units on a securities exchange. It is unlikely
that any person will make a market in the OP Units, or that an active market for
the OP Units will develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by
 
                                      S-10
<PAGE>   3108
 
AIMCO. At the same time, Moody's confirmed its existing rating on AIMCO's
preferred stock and senior debt.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were
 
                                      S-11
<PAGE>   3109
 
disqualified. Therefore, if we lose our REIT status, the funds available for
payment to our investors would be reduced substantially for each of the years
involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 0% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
          Liquidation. One alternative to our offer would be for your
     partnership to sell its assets, distribute the net liquidation proceeds to
     its partners in accordance with your partnership's agreement of limited
     partnership, and then dissolve. Partners would be at liberty to use the net
     liquidation proceeds after taxes for investment, business, personal or
     other purposes, at their option. If your partnership were to sell its
     assets and liquidate, you and your partners would not need to rely upon
     capitalization of income or other valuation methods to estimate the fair
     market value of your partnership's assets. Instead, such
 
                                      S-12
<PAGE>   3110
 
     assets would be valued through negotiations with prospective purchasers.
     However, a liquidating sale of your partnership's property would be a
     taxable event for you and your partners and could result in significant
     amounts of taxable income to you and your partners. Under your
     partnership's agreement of limited partnership, a sale of your
     partnership's assets and the subsequent liquidation of your partnership
     could occur only with the consent of the limited partners holding at least
     a majority of the units of your partnership. In the absence of such
     consent, your only option for liquidation of your investment would be to
     sell your units in a private transaction. Any such sale could be at a very
     substantial discount from your pro rata share of the fair market value of
     your partnership's property and might involve significant expense and
     delay.
 
        Continuation of Your Partnership Without the Offer. A second alternative
     would be for your partnership to continue its business without our offer. A
     number of advantages could result from the continued operation of your
     partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-
 
                                      S-13
<PAGE>   3111
 
       for-one basis, subject to adjustment in certain circumstances) or an
       equivalent amount of cash. AIMCO's Class A Common Stock is listed and
       traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."
 
TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.

limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant

property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith,
 
                                      S-15

     including liabilities under the Federal securities laws. We also pay all
costs and expenses of printing and mailing this Prospectus Supplement and the
legal fees and expenses in connection therewith. We will also pay the fees of
Stanger for providing the fairness opinions for the offer. We estimate that our
total costs and expenses in making the offer (excluding the purchase price of
the units payable to you and your partners) will be approximately
$               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a
widely-accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your
 
                                      S-16
<PAGE>   3114
 
     units to someone else or if your partnership were actually liquidated might
be higher or lower than our offer consideration. We determined our offer
consideration as follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.

     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
                                      S-18
<PAGE>   3116
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 1/4 of
1% of the gross operating revenue of your partnership's property as a
partnership administration fee from your partnership and may receive
reimbursements for expenses generated in that capacity. The property manager
received management fees of $128,000 in 1996, $136,000 in 1997 and $68,822 for
the first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Rivercrest Apartments, Ltd. is a South
Carolina limited partnership which was formed on November 30, 1983 for the
purpose of owning and operating a single apartment property located in Roswell,
Georgia, known as "Rivercrest Apartments". In 1983, it completed a private
placement of units that raised net proceeds of approximately $8,887,500.
Rivercrest Apartments consists of 312 apartment units. Your partnership has no
employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2013, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $6,841,780, payable to GMAC, which bears
interest at a rate of 7.60%. The mortgage debt is due in November 2002. Your
partnership also has a second mortgage note outstanding of $243,117, on the same
terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
                                      S-19

     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-27
<PAGE>   3125
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-28
<PAGE>   3126
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 per unit ($6,600 on an annualized
basis). This is equivalent to distributions of $     per year on the number of
Tax-Deferral      % Preferred OP Units, or distributions of $     per year on
the number of Tax-Deferral Common OP Units, that you would receive in an
exchange for each of your partnership's units. Therefore, with respect to your
units, distributions with respect to the Preferred OP Units and Common OP Units
that we are offering are expected to be        , immediately following our
offer, than the distributions with respect to your units. See "Comparison of
Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership
 
                                      S-29
<PAGE>   3127
 
were to be reduced, and you do not tender all of your units pursuant to our
offer, you will be treated as receiving a hypothetical distribution of cash
resulting from a decrease in your share of the liabilities of your partnership.
Any such hypothetical distribution of cash would be treated as a nontaxable
return of capital to the extent of your adjusted tax basis in your units and
thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock,
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 0% limited partnership interest in your partnership.
 
                                      S-30
<PAGE>   3128
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to
 
                                      S-31
<PAGE>   3129
 
continue operating as presently structured, your partnership could be forced to
borrow on terms that could result in net losses from operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   3131
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   3132
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole
 
                                      S-35
<PAGE>   3133
 
discretion, which determination shall be final and binding on all parties. The
AIMCO Operating Partnership reserves the absolute right to reject any or all
tenders of any particular unit determined by it not to be in proper form or if
the acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-36
<PAGE>   3134
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of considerations being offered, increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-37
<PAGE>   3135
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units
tendered pursuant to the offer, may postpone the purchase of, and payment for,
units tendered, and may terminate or amend the offer if at any time from or
after           , 1998 and at or before the time of acceptance for payment of
any such units (whether or not any units have theretofore been accepted for
payment and paid for) pursuant to the offer, any of the following shall occur:
 
             (a) any change (or any condition, event or development involving a
        prospective change) shall have occurred or been threatened in the
        business, properties, assets, liabilities, indebtedness, capitalization,
        condition (financial or otherwise), operations, licenses or franchises,
        management contract, or results of operations or prospects of your
        partnership or local markets in which your partnership owns or operates
        its property, including any fire, flood, natural disaster, casualty
        loss, or act of God that, which change, in the sole judgment of the
        AIMCO Operating Partnership, is or may be materially adverse to your
        partnership or the value of your units to the AIMCO Operating
        Partnership, or the AIMCO Operating Partnership shall have become aware
        of any facts relating to your partnership, its indebtedness or its

     The foregoing conditions are for the sole benefit of the AIMCO Operating
Partnership and may be asserted by the AIMCO Operating Partnership regardless of

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-41
<PAGE>   3139
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-42
<PAGE>   3140
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-43
<PAGE>   3141
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-44
<PAGE>   3142
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   3143
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             shares held in the trust. Any proceeds in excess of the
                                                             amount payable to the prohibited transferee will be
                                                             payable to the charitable beneficiaries.

                                                             its affiliates may purchase or acquire shares of Class

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   3149
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   3150
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location, and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, as of June 30, 1998, of the
       non-real estate assets of your partnership, and deducting the liabilities
       of your partnership, including mortgage debt and debt owed by your
       partnership to its general partner or its affiliates after consideration
       of any applicable subordination provisions affecting payment of such
       debt. We deducted from this value any taxes and certain other costs
       including required capital expenditures and deferred maintenance to
       derive a net equity value for your partnership of $          .
 
                                      S-55
<PAGE>   3153
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-56
<PAGE>   3154
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Different Distributions. Anticipated annualized distributions with
     respect to the Preferred OP Units are $     , current annualized
     distributions with respect to the Common OP Units are $2.25, and
     distributions with respect to your units for the six months ended June 30,
     1998 per unit ($6,600 on an annualized basis). This is equivalent to
     distributions of $     per year on the number of Tax-Deferral      %
     Preferred OP Units, or distributions of $     per year on the number of
     Tax-Deferral Common OP Units, that you would receive in an exchange for
     each of your partnership's units. Therefore, with respect to your units,
     distributions with respect to the Preferred OP Units and Common OP Units
     that we are offering are expected to be        , immediately following our
     offer, than the distributions with respect to your units. See "Comparison
     of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating
 
                                      S-57
<PAGE>   3155
 
     Partnership and are not the result of arms-length negotiations. See
"Conflicts of Interest." The general partner of your partnership and the AIMCO
Operating Partnership believe that the valuation method described in "Valuation
of Units" provides a meaningful indication of value for residential apartment
properties although there are other ways to value real estate. A liquidation in
the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
                                      S-59
<PAGE>   3157
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-61
<PAGE>   3159
 
     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with

     laws. No portion of Stanger's fee is contingent upon consummation of the
offer or the content of Stanger's opinion. Stanger has performed other services
for AIMCO in the past, including: general financial advisory services relating
to a potential acquisition by AIMCO. However, such acquisition was never
completed and no fee was paid to Stanger.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives 1/4 of
1% of the gross operating revenue of your partnership's property as a
partnership administration fee from your partnership and may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $128,000 in 1996, $136,000 in 1997 and $68,822 for
the first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Rivercrest Apartments, Ltd. is a South Carolina limited partnership which
raised net proceeds of approximately $8,887,500 in 1983 through a private
offering. The promoter for the private offering of your partnership was U.S.
Shelter Corporation. Insignia acquired your partnership in December 1990. AIMCO
acquired Insignia in October, 1998. There are currently a total of 142 limited
partners of your partnership and a total of 150 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on November 30, 1983 for the purpose of owning
and operating a single apartment property located in Roswell, Georgia, known as
"Rivercrest Apartments." Your partnership's property consists of 312 apartment
units. The total rentable square footage of your partnership's property is
404,246 square feet. Your partnership's property had an average occupancy rate
of approximately 96.47% in 1996 and 96.47% in 1997. The average annual rent per
apartment unit is approximately $8,356.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $128,000, $136,000 and $68,822, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2013
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid

borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."

six months ended June 30, 1998, compared to $494,468 for the six months ended
June 30, 1997, an increase of $90,449 18.29%. The increase was primarily due to
costs related to an exterior painting project. Management expenses totaled

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $978,648 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership are
not liable to your partnership or the limited partners and are indemnified for
any loss or damage resulting from any act or omission performed or omitted in
good faith, which does not constitute fraud, gross negligence or willful
misconduct, pursuant to the authority granted to them to promote the interests
of your partnership. Moreover, the general partners are not liable to your
partnership of the limited partner because any taxing authorities disallow or
adjust any deduction or credits in your partnership income tax returns. As a
result, unitholders might have a more limited right of action in certain
circumstances than they would have in the absence of such a provision in your
partnership's agreement of limited partnership. The general partner of your
partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partners and their affiliates will be indemnified for any loss
or damage resulting from any act or omission performed or omitted in good faith
pursuant to the authority granted to promote the interests of your partnership,
which does not constitute fraud, gross negligence or willful misconduct. As part
of its assumption of liabilities in the consolidation, AIMCO will indemnify the
general partner of your partnership and their affiliates for periods prior to
and following the consolidation to the extent of the indemnity under the terms
of your partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
has been no units transferred in sale transactions

or the same beneficial owner).

any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Rivercrest Apartments as
of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with the accounting basis for federal income tax
reporting. Accordingly, they do not include all the information and footnotes
required by the accounting basis for federal income tax reporting for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Rivercrest Apartments, Ltd.
 
     We have audited the accompanying balance sheet of Rivercrest Apartments,
Ltd. (the "Partnership") as of December 31, 1997 and the related statements of
operations, changes in partners' capital and cash flows for the year then ended.
These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Rivercrest Apartments, Ltd.,
at December 31, 1997 and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercrest Apartments, Ltd. (the "Partnership") was organized as a limited
partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated November 30, 1983 and
extending to December 31, 2013, unless terminated sooner. One hundred and fifty
limited partnership units were issued. The Partnership owns and operates a
312-unit apartment complex, Rivercrest Apartments, in Roswell, Georgia.
 
  Investment Property
 
     Investment property is stated at cost. Acquisition fees are capitalized as
a cost of real estate. The Partnership records impairment losses on long-lived
assets used in operations when events and circumstances indicated that the
assets might be impaired and the undiscounted cash flows estimated to be
generated by those assets are less than the carrying amounts of those assets. No
adjustments for impairment of value were necessary for the year ended December
31, 1997.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Risks and Uncertainties
 
     The real estate business is highly competitive. The Partnership's real
property investments are subject to competition from similar types of properties
in the vicinities in which they are located and the Partnership is not a
significant factor in its industry. In addition, various limited partnerships
have been formed by related parties to engage in business which may be
competitive with the Partnership.
 
  Cash and Cash Equivalents
 
     Cash on hand and in banks, and money market funds and certificates of
deposit with original maturities of three months or less are considered to be
unrestricted cash. At certain times, the amount of cash deposited at a bank may
exceed the limit on insured deposits.
 
  Fair Value of Financial Instruments
 
     The Partnership believes that the carrying amount of its financial
instruments (except for long-term debt) approximates their fair value due to the
short term maturity of these instruments. The fair value of the Partnership's
long-term debt, after discounting the scheduled loan payments at an estimated
borrowing rate currently available to the Partnership, approximates its carrying
value.
 
  Loan Costs
 
     Loan costs of approximately $88,000 incurred with the financing of
long-term debt are amortized on a straight-line basis over the life of the debt.
Accumulated amortization is approximately $45,000 at December 31, 1997. These
costs are included in "Other Assets".

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits." Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit and the tenant is current on its rental payments.
 
Restricted Escrow
 
     The Reserve Escrow was established to cover necessary repairs and
replacements of existing improvements, debt service, and out-of-pocket expenses
incurred for ordinary and necessary administrative tasks and payment of real
estate taxes and insurance premiums. The Partnership is required to deposit net
operating income (as defined in the mortgage note) to the reserve account until
the reserve account equals $1,000 per apartment unit or $312,000 in total. At
December 31, 1997, the balance in this reserve account is approximately
$338,000, which includes interest earned on such funds.
 
  Partnership Allocations
 
     Net earnings or loss, distributions to partners, and taxable income or loss
are allocated to the partners in accordance with the partnership agreement.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less. Rental revenue is recognized as earned.
 
  Advertising Costs
 
     The Partnership expenses the costs of advertising as incurred.
 
  Depreciation
 
     Building and improvements are depreciated using the straight-line method
over the estimated useful lives of the assets, ranging from 5 to 30 years.
 
NOTE B -- LONG-TERM DEBT
 
     Long-term debt consists of the following:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Partnership exercised interest rate buy-down options for Rivercrest
Apartments, Ltd. when the debt was refinanced, reducing the stated rate from
8.76% to 7.60%. The fee for the interest rate reduction amounted to $564,000 and
is being amortized as a loan discount on the straight-line method over the life
of the loans. The discount fee is reflected as a reduction of the mortgage notes
payable and increases the effective rate of the debt to 8.76%.
 
     Scheduled principal payments of mortgage notes payable subsequent to
December 31, 1997 are as follows (in thousands):

NOTE C -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     Affiliates of Insignia Financial Group, Inc. ("Insignia") own the
controlling ownership interest in the Partnership's Managing General Partner,
with certain affiliates of Insignia providing property management and asset
management services to the Partnership.
 
     The following payments were made to Insignia and its affiliates in 1997 (in
thousands):

<S>                                                            <C>
Property management fees....................................   $136
Reimbursements for services of affiliates...................     21
</TABLE>
 
     For the period of January 1, 1997, to August 31, 1997, the Partnership
insured its property under a master policy through an agency and insurer
unaffiliated with the Managing General Partner. An affiliate of the Managing
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the master policy. The agent assumed the financial obligations to the
affiliate of the Managing General Partner who received payments on these
obligations from the agent. The amount of the Partnership's insurance premiums
that accrued to the benefit of the affiliate of the Managing General Partner by
virtue of the agent's obligations was not significant.
 
     Insignia entered into an Agreement and Plan of Merger, dated as of May 26,
1998, (as subsequently amended and restated, the "Merger Agreement") with
Apartment Investment and Management Company ("AIMCO"), pursuant to which
Insignia will merge its national residential property management operations and
its controlling interest in Insignia Properties Trust with and into AIMCO, with
AIMCO as the survivor. Consummation of the Merger, which is anticipated to occur
in the third quarter of 1998, is subject to certain conditions, including the
approval of the stockholders of Insignia (but not the approval of the
stockholders of AIMCO). If the closing occurs, AIMCO will then control the
General Partner of the Partnership.

NOTE F -- YEAR 2000 (UNAUDITED)
 
     The Partnership is dependent upon the General Partner and Insignia for
management and administrative services. Insignia has completed an assessment and
will have to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter (the "Year 2000 Issue"). The project is estimated to be completed not
later than December 31, 1998, which is prior to any anticipated impact on its
operating systems. The General Partner believes that with modifications to
existing software and conversions to new software, the Year 2000 Issue will not
pose significant operational problems for its computer systems. However, if such
modifications and conversions are not made, or are not completed timely, the
Year 2000 Issue could have a material impact on the operations of the
Partnership.
 
NOTE G EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Rivercrest Apartments, Ltd.
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Rivercrest Apartments, Ltd.
(the "Partnership") as of December 31, 1997, and the related statements of
revenues, expenses and changes in partners' deficit -- Federal income tax basis
and cash flows -- Federal income tax basis for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note A, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Rivercrest Apartments, Ltd. as of December 31, 1997 and its revenues, expenses,
changes in partners' deficit and cash flows for the year then ended, on the
basis of accounting described in Note A.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercrest Apartments, Ltd. (the "Partnership") was organized as a limited
partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated November 30, 1983 and
extending to December 31, 2013, unless terminated sooner. The Partnership owns
and operates a 312-unit apartment complex, Rivercrest Apartments, in Roswell,
Georgia.
 
  Basis of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
  Depreciation
 
     Under ACRS, depreciation is based on accelerated methods (1) for real
property over periods of 15 years for additions prior to March 16, 1984, 18
years for additions after March 15, 1984 and before May 9, 1985 and 19 years for
additions after May 8, 1985 and before January 1, 1987 and (2) for personal
property over 5 years for additions prior to January 1, 1987. As a result of the
Tax Reform Act of 1986, for additions after December 31, 1986, the MACRS is used
(1) for real property additions over 27 1/2 years and (2) for personal property
additions over 7 years.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and includes them in "Receivables and deposits". Deposits
are refunded when the tenant vacates the apartment if there has been no damage
to the unit.
 
  Restricted Escrow
 
     The Reserve Escrow was established to cover necessary repairs and
replacements of existing improvements, debt service, and out-of-pocket expenses
incurred for ordinary and necessary administrative tasks and

payment of real estate taxes and insurance premiums. The Partnership is required
to deposit net operating income (as defined in the mortgage note) to the reserve
account until the reserve account equals $1,000 per apartment unit or $312,000
in total. At December 31, 1997, the balance in this reserve account is
approximately $338,000, which includes interest earned on such funds.
 
  Deferred Charges
 
     1)  Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital of
$841,000 have been capitalized and represent a deferred charge which will be
expensed upon termination of the Partnership.
 
     2)  Loan Costs
 
     Loan costs of approximately $88,000 incurred with the refinancing of the
mortgage notes payable are being amortized on a straight-line basis over the
life of the loans. Accumulated amortization at December 31, 1997 is
approximately $45,000.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.

     The Partnership exercised interest rate buy-down options for Rivercrest
Apartments, Ltd. when the debt was refinanced, reducing the stated rate from
8.76% to 7.60%. The fee for the interest rate reduction amounted to $564,000 and
is being amortized as a loan discount on the straight-line method over the life
of the loans. The discount fee is reflected as a reduction of the mortgage notes
payable and increases the effective rate of the debt to 8.76%.

The Partners
Rivercrest Apartments, Ltd.
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Rivercrest Apartments, Ltd.
(the "Partnership") as of December 31, 1996, and the related statements of
revenues, expenses and changes in partners' deficit -- Federal income tax basis
and cash flows -- Federal income tax basis for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note A, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Rivercrest Apartments, Ltd. as of December 31, 1996 and its revenues, expenses,
changes in partners' deficit and cash flows for the year then ended, on the
basis of accounting described in Note A.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercrest Apartments, Ltd. (the "Partnership") was organized as a limited
partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated November 30, 1983 and
extending to December 31, 2013, unless terminated sooner. The Partnership owns
and operates a 312-unit apartment complex, Rivercrest Apartments, in Roswell,
Georgia.
 
  Basis of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
  Depreciation
 
     Under ACRS, depreciation is based on accelerated methods (1) for real
property over periods of 15 years for additions prior to March 16, 1984, 18
years for additions after March 15, 1984 and before May 9, 1985 and 19 years for
additions after May 8, 1985 and before January 1, 1987 and (2) for personal
property over 5 years for additions prior to January 1, 1987. As a result of the
Tax Reform Act of 1986, for additions after December 31, 1986, the MACRS is used
(1) for real property additions over 27 1/2 years and (2) for personal property
additions over 7 years.
 
  Cash and Cash Equivalents -- Unrestricted
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and it considers these deposits to be restricted cash.
Deposits are refunded when the tenant vacates the apartment if there has been no
damage to the unit.
 
  Restricted Escrow
 
     The Reserve Escrow was established to cover necessary repairs and
replacements of existing improvements, debt service, and out-of-pocket expenses
incurred for ordinary and necessary administrative tasks and

    NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS -- (CONTINUED)
 
payment of real estate taxes and insurance premiums. The Partnership is required
to deposit net operating income (as defined in the mortgage note) to the reserve
account until the reserve account equals $1,000 per apartment unit or $312,000
in total. At December 31, 1996, the balance in this reserve account is
approximately $319,000, which includes interest earned on such funds.
 
  Deferred Charges
 
     1) Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital of
$841,000 have been capitalized and represent a deferred charge which will be
expensed upon termination of the Partnership.
 
     2) Loan Costs
 
     Loan costs of approximately $88,000 incurred with the refinancing of the
mortgage notes payable are being amortized on a straight-line basis over the
life of the loans. Accumulated amortization at December 31, 1996 is
approximately $36,000.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
NOTE B -- LONG-TERM DEBT
 
     Long-term debt consists of the following (dollar amounts in thousands):

The Partners
Rivercrest Apartments, Ltd.
 
     We have audited the accompanying statement of assets, liabilities and
partners' deficit -- Federal income tax basis of Rivercrest Apartments, Ltd.
(the "Partnership") as of December 31, 1995, and the related statements of
revenues, expenses and changes in partners' deficit -- Federal income tax basis
and cash flows -- Federal income tax basis for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As described in Note 1, these financial statements have been prepared on
the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' deficit of
Rivercrest Apartments, Ltd. as of December 31, 1995 and its revenues, expenses,
changes in partners' deficit and cash flows for the year then ended, on the
basis of accounting described in Note 1.

           NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1995
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Rivercrest Apartments, Ltd. (the "Partnership") was organized as a limited
partnership under the laws of the State of South Carolina pursuant to a
Certificate and Agreement of Limited Partnership dated November 30, 1983 and
extending to December 31, 2013, unless terminated sooner. The Partnership owns
and operates a 312-unit apartment complex, Rivercrest Apartments, in Roswell,
Georgia.
 
  Basis of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Depreciation
 
     Under ACRS, depreciation is based on accelerated methods (1) for real
property over periods of 15 years for additions prior to March 16, 1984, 18
years for additions after March 15, 1984 and before May 9, 1985 and 19 years for
additions after May 8, 1985 and before January 1, 1987 and (2) for personal
property over 5 years for additions prior to January 1, 1987. As a result of the
Tax Reform Act of 1986, for additions after December 31, 1986, the MACRS is used
(1) for real property additions over 27 1/2 years and (2) for personal property
additions over 7 years.
 
  Restricted Escrow
 
     The Reserve Escrow was established with the refinancing proceeds for the
refinanced property. These funds were established to cover necessary repairs and
replacements of existing improvements, debt service, and out-of-pocket expenses
incurred for ordinary and necessary administrative tasks and payment of real
estate taxes and insurance premiums. The Partnership is required to deposit net
operating income (as defined in the mortgage note) from the refinanced property
to the reserve account until the reserve account equals $1,000 per apartment
unit or $312,000 in total. At December 31, 1995 the balance in this reserve
account is $320,435.
 
  Deferred Charges
 
     1) Offering Costs
 
     Costs incurred in connection with the solicitation of equity capital of
$840,823 have been capitalized and represent a deferred charge which will be
expensed upon termination of the Partnership.

    NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS -- (CONTINUED)
 
     2) Loan Costs
 
     In connection with the refinancing of certain mortgage notes payable, loan
costs of $87,730 were incurred which are being amortized on a straight-line
basis over the life of the loans. Accumulated amortization at December 31, 1995
was $26,767.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.

</TABLE>
 
     The Partnership exercised interest rate buy-down options for Rivercrest
Apartments, Ltd. when the debt was refinanced, reducing the stated rate from
8.76% to 7.60%. The fee for the interest rate reduction amounted to $564,048 and
is being amortized as a loan discount on the straight-line method over the life
of the loans. The discount fee is reflected as a reduction of the mortgage notes
payable and increases the effective rate of the debt to 8.76%.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3215
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3216
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3221
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3222
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $.40 per unit for the six months
     ended June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY

     SUBJECT TO SPECIAL

<PAGE>   3223
 
     TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX
     CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
     TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX
     MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS
     AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX
     CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if 50% or more of the
     total interests in your partnership are transferred within a 12-month
     period. If we acquire a significant percentage of the interest in your
     partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using
 
                                       S-4
<PAGE>   3224
 
     our best judgment, but our valuation is just an estimate. Although the
     direct capitalization method is a widely-accepted way of valuing real
     estate, there are a number of other methods available to value real estate,
     each of which may result in different valuations of the property. The
     proceeds that you would receive if you sold your units to someone else or
     if your partnership were actually liquidated might be higher or lower than
     our offer consideration. An actual liquidation may also result in your
     paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the
 
                                       S-5

     expiration of the offer, and you must follow the instructions provided with
     the Letter of Transmittal and any instructions of the Information Agent.

     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.

     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by

RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3227
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   3228
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   3229
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's reaffirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   3230
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   3231
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited Partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
 
                                      S-12
<PAGE>   3232
 
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
                                      S-13
<PAGE>   3233
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."
 
TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %
Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any combination
of such forms of consideration for your units. The offer is made upon the terms
and subject to the conditions set forth in this Prospectus Supplement, the
accompanying Prospectus and the accompanying Letter of Transmittal, including
the instructions thereto, as the same may be supplemented or amended from time
to time (the "Letter of Transmittal"). To be eligible to receive Tax-Deferral
     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an

     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   3235
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $47,992 in 1996, $50,739 in 1997 and $26,057 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Salem Arms of Augusta Limited
Partnership is a South Carolina limited partnership which was formed on July 10,
1974 for the purpose of owning and operating a single

<PAGE>   3238
 
apartment property located in Augusta, Georgia, known as "Salem Arms of
Augusta". Salem Arms of Augusta consists of 136 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2014, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $1,272,189, payable to Reilly Mortgage,
which bears interest at a rate of 8.50%. The mortgage debt is due in July 2012.
Your partnership's agreement of limited partnership prohibit your general
partner from lending funds to your partnership. Currently, the general partner
of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3246
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-27
<PAGE>   3247
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of
$0.00 with respect to your units, distributions with respect to the Preferred OP
Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your
 
                                      S-28
<PAGE>   3248
 
partnership. Any such hypothetical distribution of cash would be treated as a
nontaxable return of capital to the extent of your adjusted tax basis in your
units and thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if 50% or more of the total interests in your
partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
                                      S-29
<PAGE>   3249
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Alternatively, your only option for liquidation
would be to sell your units in a private transaction. Any such sale likely would
be at a very substantial discount from your pro rata share of the fair market
value of your partnership's property and might involve significant expense and
delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
                                      S-30
<PAGE>   3250
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.

<PAGE>   3252
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   3253
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   3254
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   3255
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   3256
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     acquire beneficial ownership of more than four percent of the units, or
     shall have been granted any option, warrant or right, conditional or
     otherwise, to acquire beneficial ownership of more than four percent of the
     units, or (ii) any person or group shall have entered into a definitive
     agreement or an agreement in principle or made a proposal with respect to a
     merger, consolidation, purchase or lease of assets, debt refinancing or
     other business combination with or involving your partnership; or

     the AIMCO Operating Partnership shall not have adequate cash or financing
     commitments available to pay the cash portion of the offer consideration.
 
     The foregoing conditions are for the sole benefit of the AIMCO Operating
Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   3260
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   3261
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-42
<PAGE>   3262
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-43
<PAGE>   3263
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   3264
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   3265
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from

DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   3270
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   3271
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   3274
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-55
<PAGE>   3275
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1998 distributions of $0.00 with
     respect to your units, distributions with respect to the Preferred OP Units
     and Common OP Units being offered are expected to be      , immediately
     following the offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-56
<PAGE>   3276
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general

"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth

changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not
 
                                      S-59
<PAGE>   3279
 
     limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the
 
                                      S-60
<PAGE>   3280
 
     value of the partnership's property or other balance sheet assets and
liabilities or other information reviewed between the date of such information
provided and the date of the Fairness Opinion; that your partnership, AIMCO, and
the management of the partnership's property are not aware of any information or
facts that would cause the information supplied to Stanger to be incomplete or
misleading; that the highest and best use of the partnership's property is as
improved; and that all calculations were made in accordance with the terms of
your partnership's agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for their services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $47,992 in 1996, $50,739 in 1997 and $26,057 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership's
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Salem Arms of Augusta Limited Partnership is a South Carolina limited
partnership. Insignia acquired your partnership in December 1990. AIMCO acquired
Insignia in October, 1998. There are currently a total of 15 limited partners of
your partnership and a total of 9,500 units of your partnership outstanding.
Your partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on July 10, 1974 for the purpose of owning and
operating a single apartment property located in Augusta, Georgia, known as
"Salem Arms of Augusta." Your partnership's property consists of 136 apartment
units. There are 36 two-bedroom apartments and 100 three-bedroom apartments.
Your partnership's property had an average occupancy rate of approximately
91.18% in 1996 and 91.18% in 1997.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $47,992, $50,739 and $26,057, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2014
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All
 
                                      S-72
<PAGE>   3292
 
     capital improvement and renovation costs are expected to be paid from
operating cash flows, cash reserves, or from short-term or long-term borrowings.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $1,272,189, payable to Reilly Mortgage, which bears interest at a
rate of 8.50%. The mortgage debt is due in July 2012. Your partnership's
agreement of limited partnership does not prohibit the general partner of your
partnership from lending funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $241,285 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership are
not liable, responsible or accountable in damages or otherwise to any of the
partners for any acts performed by it in good faith within the scope of the
authority conferred on it by your partnership's agreement of limited
partnership. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership's agreement of limited partnership does not provide for
the indemnification of the general partners or their affiliates.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter.

</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,

     understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expense) in its capacity as general partner of your
partnership as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Salem Arms as of June
30, 1998 and for the six months ended June 30, 1998 and 1997 have been prepared
in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                         REPORT OF INDEPENDENT AUDITORS
 
The General Partners
Salem Arms of Augusta Limited Partnership
 
     We have audited the accompanying balance sheet of Salem Arms of Augusta
Limited Partnership (FHA Project No. 061-35036-PM) as of December 31, 1997 and
the related statements of profit and loss, changes in deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Salem Arms of Augusta
Limited Partnership at December 31, 1997, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

1.  SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership is organized as a limited partnership formed to acquire an
interest in real property located in Augusta, Georgia and operates thereon an
apartment complex of 136 units, under Section 221(d)(4) of the National Housing
Act. Such projects are regulated by HUD as to rent charges and operating
methods. The regulatory agreement limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Depreciation is computed principally by an accelerated method over
estimated useful lives of 3 to 40 years.
 
  Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents except for imprest
balances of petty cash.
 
  Income Taxes
 
     Income taxes have not been recorded in the accompanying financial
statements because they accrue directly to the partners.
 
  Management Agreement
 
     The Partnership pays management fees equal to 7 percent of gross
collections to Insignia Residential Group.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2.  LONG-TERM DEBT
 
     A mortgage note is payable in monthly installments of $12,897 until July
2012, including interest at 8.5%, to Reilly Mortgage Group. The note is
collateralized by pledge of land and buildings and, in addition, is insured by
HUD. The note was confirmed in writing to our independent public accountants.
Principal maturities for the next five years are as follows:

                         REPORT OF INDEPENDENT AUDITORS
 
The General Partners
Salem Arms of Augusta Limited Partnership
 
     We have audited the accompanying balance sheet of Salem Arms of Augusta
Limited Partnership (FHA Project No. 061-35036-PM) as of December 31, 1996 and
the related statements of profit and loss, changes in deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Salem Arms of Augusta
Limited Partnership at December 31, 1996, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
1.  SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership is organized as a limited partnership formed to acquire an
interest in real property located in Augusta, Georgia and operates thereon an
apartment complex of 136 units, under Section 221(d)4 of the National Housing
Act. Such projects are regulated by HUD as to rent charges and operating
methods. The regulatory agreement limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Depreciation is computed principally by an accelerated method over
estimated useful lives of 3 to 40 years.
 
  Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents except for imprest
balances of petty cash.
 
  Income Taxes
 
     Income taxes have not been recorded in the accompanying financial
statements because they accrue directly to the partners.
 
  Management Agreement
 
     The Partnership pays management fees equal to 7 percent of gross
collections to Insignia Management Group.
 
  Financial Accounting Standards Statement No. 107 Disclosures
 
     The carrying amounts reported in the balance sheet, for those financial
instruments described in the schedule of funds in financial institutions
included in the supporting data required by HUD listed on the contents page,
approximate those assets' fair value. Payment of long-term liabilities are
generally dependent upon the Partnership's ability to achieve cash flow, the
partners providing additional funds, the sale of the project or refinancing of
the mortgage at the end of the Regulatory Agreement. Management believes that
estimating the fair value of these long-term liabilities is either not
appropriate or, because of excess costs, considers estimation of fair value to
otherwise be impracticable.
 
  Long-Lived Assets
 
     During 1996, the Partnership adopted FASB Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", which requires impairment losses to be recognized for long-lived assets
used in operations when indicators of impairment are present and the
undiscounted cash flows are not sufficient to recover the assets' carrying
amount. The impairment loss is measured by comparing the fair value of the asset
to its carrying amount. The adoption of FASB No. 121 did not have a material
effect on the Partnership's financial statements.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2.  LONG-TERM DEBT
 
     A mortgage note is payable in monthly installments of $12,897 until July
2012, including interest at 8.5%, to Reilly Mortgage Group. The note is
collateralized by pledge of land and buildings and, in addition, is insured by
HUD. The note was confirmed in writing to our independent public accountants.
Principal maturities for the next five years are as follows:

2000.......................................................   55,433
2001.......................................................   60,333

     During the year, the Partnership incurred interest costs on the mortgage
note of $115,250 and paid interest costs of $115,066.

NOTE 4 EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The General Partners
Salem Arms of Augusta Limited Partnership
 
     We have audited the accompanying balance sheet of Salem Arms of Augusta
Limited Partnership (FHA Project No. 061-35036-PM) as of December 31, 1995 and
the related statements of profit and loss, changes in deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Salem Arms of Augusta
Limited Partnership at December 31, 1995, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                               DECEMBER 31, 1995
 
1.  SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership is organized as a limited partnership formed to acquire an
interest in real property located in Augusta, Georgia and operates thereon an
apartment complex of 136 units, under Section 221(d)4 of the National Housing
Act. Such projects are regulated by HUD as to rent charges and operating
methods. The regulatory agreement limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Depreciation is computed principally by an accelerated method over
estimated useful lives of 3 to 40 years.
 
  Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents except for imprest
balances of petty cash.
 
  Income Taxes
 
     Income taxes have not been recorded in the accompanying financial
statements because they accrue directly to the partners.
 
  Management Agreement
 
     The Partnership pays management fees equal to 7 percent of gross
collections to a wholly-owned subsidiary of Insignia Financial Group, Inc.
 
  Financial Accounting Standards Statement No. 107 Disclosures
 
     The carrying amounts reported in the balance sheet, for those financial
instruments described in the schedule of funds in financial institutions
included in the supporting data required by HUD listed on the contents page,
approximate those assets' fair value. Payment of long-term liabilities are
generally dependent upon the Partnership's ability to achieve cash flow, the
partners providing additional funds, the sale of the project or refinancing of
the mortgage at the end of the Regulatory Agreement. Management believes that
estimating the fair value of these long-term liabilities is either not
appropriate or, because of excess costs, considers estimation of fair value to
otherwise be impracticable.
 
2.  LONG-TERM DEBT
 
     A mortgage note is payable in monthly installments of $12,897 until July
2012, including interest at 8.5%, to Reilly Mortgage Group. The note is
collateralized by pledge of land and buildings and, in addition, is

4.  GAIN ON SALE OF LAND
 
     During the year, a portion of the Partnership's land was seized by Richmond
County under an order of condemnation. The Partnership received $9,114 for the
land which had a cost basis of $3,032. This resulted in a gain on sale of land
of $6,082.
 
5.  EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3338
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3339
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Shaker Square, L.P. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3344
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3345
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid no distributions for the six months ended June 30,
     1998. We will pay fixed quarterly distributions of $               per unit
     on the Tax-Deferral   % Preferred OP Units before any distributions are
     paid to holders of Tax-Deferral Common OP Units. We pay quarterly
     distributions on the Tax-Deferral Common OP Units based on our funds from
     operations for that quarter. For the six months ended June 30, 1998, we
     paid distributions of $1.125 on each of the Tax-Deferral Common OP Units
     (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   3347
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit date compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-8
<PAGE>   3351
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-9
<PAGE>   3352
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                      S-10
<PAGE>   3353
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-11
<PAGE>   3354
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-12
<PAGE>   3355
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 1.25% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-13
<PAGE>   3356
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

<PAGE>   3358
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units

unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a
 
                                      S-17
<PAGE>   3360
 
     number of factors, including your financial needs, other financial
opportunities available to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment,
 
                                      S-18
<PAGE>   3361
 
voting rights, distributions and liquidity and transferability/redemption. For
example, unlike the AIMCO OP Units, you have no redemption rights with respect
to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $19,000
annually and may receive reimbursements for expenses generated in that capacity
from your partnership. The property manager received management fees of $61,478
in 1996, $64,410 in 1997 and $32,059 for the first six months of 1998. We have
no current intention of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Shaker Square, L.P. is a Delaware
limited partnership which was formed on October 16, 1985 for the purpose of
owning and operating a single apartment property located in Whitehall, Ohio,
known as "Shaker Square Apartments." In 1985, it completed a private placement
of units that raised net proceeds of approximately $2,656,000. Your partnership
has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on July 1, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time
 
                                      S-19
<PAGE>   3362
 
period. An investment in your partnership is a finite life investment in which
partners receive regular cash distributions out of your partnership's
distributable cash flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,375,603, payable to Marine Midland and
Bank of America, which bears interest at a rate of 7.60%. The mortgage debt is
due in November 2002. Your partnership also has a second mortgage note
outstanding of $119,949, on the same terms as the current mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-27
<PAGE>   3370
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-28
<PAGE>   3371
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $0.00 per unit. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 1.25% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-30
<PAGE>   3373
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the unit, of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties may improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
                                      S-31
<PAGE>   3374
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   3376
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   3377
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   3378
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-36
<PAGE>   3379
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.

     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

<PAGE>   3383
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-41
<PAGE>   3384
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-43
<PAGE>   3386
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-44
<PAGE>   3387
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46
<PAGE>   3389
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   3394
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   3395
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   3397
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-55
<PAGE>   3398
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $0.00 per unit. Therefore,
     distributions with respect to the Preferred OP Units and Common OP Units
     that we are offering are expected to be        , immediately following our
     offer, than the distributions with respect to your units. See "Comparison
     of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-56
<PAGE>   3399
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-60
<PAGE>   3403
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $19,000
annually and may receive reimbursement for expenses generated in that capacity.
The property manager received management fees of $61,478 in 1996, $64,410 in
1997 and $32,059 for the first six months of 1998. The AIMCO Operating
Partnership has no current intention of changing the fee structure for the
manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Shaker Square, L.P. is a Delaware limited partnership which raised net
proceeds of approximately $2,656,000 in 1985 through a private offering. The
promoter for the private offering of your partnership was Freeman Investment
Real Estate. Insignia acquired your partnership in December 1991. AIMCO acquired
Insignia in October, 1998. There are currently a total of 35 limited partners of
your partnership and a total of 45 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on October 16, 1985 for the purpose of owning
and operating a single apartment property located in Whitehall, Ohio, known as
"Shaker Square Apartments." Your partnership's property consists of 194
apartment units. There are 194 two-bedroom apartments. The total rentable square
footage of your partnership's property is 285,528 square feet. Your
partnership's property had an average occupancy rate of approximately 95.88% in
1996 and 95.88% in 1997. The average annual rent per apartment unit is
approximately $6,255.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $61,478, $64,410 and $32,059, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on July 1, 2015 unless
earlier dissolved. Your partnership has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,375,603, payable to Marine Midland and Bank of America, which
bears interest at a rate of 7.60%. The mortgage debt is due in November 2002.
Your partnership also has a second mortgage note outstanding of $119,949, on the
same terms as the current mortgage note. Your partnership's agreement of limited
partnership also allows the general partner of your partnership to lend funds to
your partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your

     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,

maintenance, advertising and marketing, property taxes and insurance, totaled
$569,524 for the year ended December 31, 1996, compared to $528,020 for the year
ended December 31, 1995, an increase of $41,504 or 7.86%. This is primarily due

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $212,696 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership and
their affiliates are not liable, responsible or accountable, in damages or
otherwise to your partnership or any limited partner for any acts performed by
any of them which are reasonably believed by them to be within the scope of the
authority conferred on them by your partnership's agreement of limited
partnership, excepting only acts of malfeasance, gross negligence or actual
misrepresentation. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest."
 
     The general partners and their affiliates are entitled to indemnification
by your partnership for any and all acts performed by them in the good faith
belief that the act or omission was in the best interests of your partnership
and which are reasonable within the scope of the authority conferred upon them
by your partnership's agreement of limited partnership or by your partnership,
excepting only acts of malfeasance, gross negligence or actual
misrepresentation; provided, however, that such indemnity will be paid out of
and only to the extent of partnership assets. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The
original cost per unit was $280.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been
 
                                      S-77
<PAGE>   3420
 
effectuated. The general partner of your partnership estimates, based solely on
the transfer records of your partnership (or your partnership's transfer agent),
that there have been no units transferred in sale transactions (excluding
transactions believed to be between related parties, family members or the same
beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     AIMCO currently owns a 1.25% limited partnership interest in your
partnership. Except as described above, neither AIMCO, nor, to the best of its
knowledge, any of its affiliates, (i) beneficially own or have a right to
acquire any units, (ii) have effected any transaction in the units, or (iii)
have any contract, arrangement, understanding or relationship with any other
person with respect to any securities of your partnership, including, but not
limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.
 
MANAGEMENT COMPENSATION
 
     The general partner of your partnership received total compensation which
includes all monies paid to the general partner by your partnership including
reimbursement of expenses in its capacity as general partner of your partnership
as described in the following table:

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Shaker Square, L.P. as
of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- SUBSEQUENT EVENT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Shaker Square, Limited:
 
     We have audited the accompanying statements of assets, liabilities and
partners' deficit -- income tax basis of Shaker Square, Limited as of December
31, 1997 and 1996, and the related statements of revenues and expenses and
changes in partners' deficit -- income tax basis and cash flows -- income tax
basis for the years then ended. These financial statements are the
responsibility of the partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     As described in Note A, these financial statements were prepared on the
basis of accounting Shaker Square, Limited uses for Federal income tax purposes,
which is a comprehensive basis of accounting other than generally accepted
accounting principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Shaker Square, Limited as of
December 31, 1997 and 1996, and the results of its operations and its cash flows
for the years then ended, on the basis of accounting described in Note A.

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Shaker Square, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Certificate
and Agreement of Limited Partnership dated October 16, 1985. The Partnerships
owns and operates a 194 unit multi-family housing complex, Shaker Square
Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded as income in the year received rather than in the year earned and
(2) buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS, and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include unamortized deferred
loan costs of $66,894 and $80,503, respectively, which are amortized over the
term of the related borrowing. They are shown net of accumulated amortization.
Also included in other assets are syndication costs of $221,836 which are not
amortized.

        NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the
following:

Reserve Escrow -- A portion of the proceeds of the 1992 loan
  refinancing was used to establish a reserve escrow. The
  funds are used for certain repair work, debt service,
  expenses and property taxes or insurance. The funds in the
  reserve escrow exceed the minimum balance required to be
  maintained by the lender during the term of the loan......  $206,537   $198,048

     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid balance at the
time of prepayment or the present value of the excess of interest which would be
incurred at the stated rate under the notes over the interest which would be
incurred at the Treasury constant maturity for U.S. Government obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership has no administrative or management employees and is
dependent on the Managing General Partner and its affiliates for the management
and administration of all partnership activities. The Partnership is obligated
to pay a property management fee equal to 5% of gross monthly collections. In
addition to the management fee, the partnership agreement provides for payments
to affiliates of a partnership administration fee and reimbursement of certain
expenses incurred by affiliates on behalf of the Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Shaker Square, Limited:
 
     We have audited the accompanying statements of assets, liabilities and
partners' deficit -- income tax basis of Shaker Square, Limited as of December
31, 1996 and 1995, and the related statements of revenues and expenses and
changes in partners' deficit -- income tax basis and cash flows income tax basis
for the years then ended. These financial statements are the responsibility of
the partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     As described in Note A, these financial statements were prepared on the
basis of accounting Shaker Square, Limited uses for Federal income tax purposes,
which is a comprehensive basis of accounting other than generally accepted
accounting principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Shaker Square, Limited as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for the years then ended, on the basis of accounting described in Note A.

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Shaker Square, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Delaware pursuant to a Certificate
and Agreement of Limited Partnership dated October 16, 1985. The Partnerships
owns and operates a 194 unit multi-family housing complex, Shaker Square
Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded as income in the year received rather than in the year earned and
(2) buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization. Also included in other assets are syndication costs
of $221,836 which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.

  Reclassifications

presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3444
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3445
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Shannon Manor Apartments, a Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3450
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3451
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $2.50 per unit for the six months
     ended June 30, 1998 (equivalent to $5.00 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units, that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if more than 50% or
     more of the total interests in your partnership are transferred within a
     12-month period. If we acquire a significant percentage of the interest in
     your partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, if there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.

<PAGE>   3453
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3456
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
                                       S-8
<PAGE>   3457
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   3458
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
                                      S-10
<PAGE>   3459
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain
 
                                      S-11
<PAGE>   3460
 
pension trusts, registered investment companies and Mr. Considine). Our charter
also prohibits anyone from buying shares if the purchase would result in us
losing our REIT status. If you or anyone else acquires shares in excess of the
ownership limit or in violation of the ownership requirements of the Internal
Revenue Code for REITs, the transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 0% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of
     related partners holding at least 67% of the units of your partnership. In
     the absence of such consent, your only option for liquidation of your
     investment would be to sell your units in a private transaction. Any such
     sale could be at a very substantial discount from your pro rata share of
     the fair market value of your partnership's property and might involve
     significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
 
                                      S-12
<PAGE>   3461
 
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future
 
                                      S-13

      increase in the AIMCO stock price and from any future increase in
      distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated

actions by or with any domestic or foreign governmental authority or

acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making

securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the

will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the
 
                                      S-17
<PAGE>   3466
 
fairness opinion. Based on its analysis, and subject to the assumptions,
limitations and qualifications cited in its opinion, Stanger concluded that our
offer consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, unlike with the general partner of the AIMCO Operating
Partnership, the liability of the general partners of your partnership to your
partnership or the limited partners for acts performed in their capacity as
general partner is not limited.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity. The property manager received management fees of
$108,745 in 1996, $112,600 in 1997 and $58,554 for the first six months of 1998.
We have no current intention of changing the fee structure for your property
manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. Shannon Manor Apartments, a Limited
Partnership is a South Carolina limited partnership which was formed on December
22, 1972 for the purpose of owning and operating a single apartment property
located in Durham, North Carolina, known as Shannon Manor Apartments. In 1972,
it completed a private placement of units. Your partnership has no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on October 1, 2017, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,258,233, payable to USGI, Inc., which
bears interest at a rate of 7.00%. The mortgage debt is due in August 2014. Your
partnership's agreement of limited partnership does not prohibit your general
partner to lend funds to your partnership. Currently, the general partner of
your partnership has no outstanding loans to the partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3475
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-27
<PAGE>   3476
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $2.50 per unit (equivalent to
$5.00 on an annualized basis). This is equivalent to distributions of $
per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $       per year on the number of Tax-Deferral Common OP Units,
that you would receive in an exchange for each of your partnership's units.
Therefore, distributions with respect to the Preferred OP Units and Common OP
Units that we are offering are expected to be        , immediately following our
offer, than the distributions with respect to your units. See "Comparison of
Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership
 
                                      S-28
<PAGE>   3477
 
were to be reduced, and you do not tender all of your units pursuant to our
offer, you will be treated as receiving a hypothetical distribution of cash
resulting from a decrease in your share of the liabilities of your partnership.
Any such hypothetical distribution of cash would be treated as a nontaxable
return of capital to the extent of your adjusted tax basis in your units and
thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
 If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service ("Moody's") revised its outlook for the ratings
of AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of the more difficult general capital
market conditions. Moody's noted that AIMCO's access to the public markets may
prove challenging in light of the volatility in both the equity and capital
markets for REITs. Moody's assigned a "ba3" rating to the Class I Preferred
Stock proposed to be issued by AIMCO, and confirmed its previous ratings related
to AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high level of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on
 
                                      S-29
<PAGE>   3478
 
Stanger's expertise and strong reputation in this area of work. The parties
entered into a definitive agreement dated August 28, 1998 for Stanger to provide
such fairness opinion for your partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 67% of the units of in your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
                                      S-30
<PAGE>   3479
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   3481
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   3482
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   3483
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   3484
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   3486
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     or other lending institutions, or (viii) in the case of any of the

        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   3489
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   3491
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such

     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   3494
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   3499
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   3500
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

<PAGE>   3501
 
FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-54
<PAGE>   3503
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-55
<PAGE>   3504
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $2.50 per unit (equivalent to $5.00
     on an annualized basis). This is equivalent to distributions of $       per
     year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $       per year on the number of Tax-Deferral Common OP
     Units, that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-56
<PAGE>   3505
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-57

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."

                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.

CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
in that capacity. The property manager received management fees of $108,745 in
1996, $112,600 in 1997 and $58,554 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Shannon Manor Apartments is a South Carolina limited partnership which
raised net proceeds of approximately $          in 1972 through a private
offering. Insignia acquired your partnership in December 1990. AIMCO acquired
Insignia in October, 1998. There are currently a total of 17 limited partners of
your partnership and a total of 9,649 units of your partnership outstanding.
Your partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on December 22, 1972 for the purpose of owning
and operating a single apartment property located in Durham, North Carolina,
known as "Shannon Manor Apartments." Your partnership's property consists of 230
apartment units. There are 24 one-bedroom apartments, 138 two-bedroom apartments
and 68 three-bedroom apartments. The total rentable square footage of your
partnership's property is 205,480 square feet. Your partnership's property had
an average occupancy rate of approximately 98.26% in 1996 and 98.26% in 1997.
The average annual rent per apartment unit is approximately $6,609.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $108,745, $112,600 and $58,554, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on October 1, 2017 unless
earlier dissolved. Your partnership has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $2,258,233, payable to USGI, Inc., which bears interest at a rate
of 7.00%. The mortgage debt is due in August 2014. Your partnership's agreement
of limited partnership does not prohibit the general partner of your partnership
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership are
not liable to the limited partners for any act or omission performed or omitted
in good faith, pursuant to the authority granted to them to promote the
interests of your partnership, except for act or omission which constitute fraud
or gross negligence. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership's agreement of limited partnership does not provide for
indemnification of the general partners and their affiliates.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter.

1997........................................................       1.32
1998 (through June 30)......................................       2.50
</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no sale transactions (excluding transactions believed to be between
related parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Shannon Manor Apartments
as of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that accounting measurements at interim dates inherently
involve greater reliance on estimates than at year-end. The results of
operations for the interim periods presented are not necessarily indicative of
the results for the entire year.

The General Partners
Shannon Manor Apartments, A Limited Partnership
 
     We have audited the accompanying balance sheet of Shannon Manor Apartments,
A Limited Partnership (FHA Project No. 053-35064-PM) as of December 31, 1997 and
the related statements of profit and loss, changes in deficit/equity and cash
flows for the year then ended. These financial statements are the responsibility
of the Partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Shannon Manor Apartments, A
Limited Partnership at December 31, 1997, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership is organized as a limited partnership formed to acquire an
interest in real property located in Durham, North Carolina and to operate
thereon an apartment complex of 230 units, under Section 221(d)4 of the National
Housing Act. Such projects are regulated by HUD as to rent charges and operating
methods. The regulatory agreement limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Depreciation is computed principally by the straight-line and accelerated
methods over estimated useful lives of 3 to 40 years.
 
  Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents except for imprest
balances of petty cash.

the related statements of profit and loss, changes in deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,

1. SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership is organized as a limited partnership formed to acquire an
interest in real property located in Durham, North Carolina and to operate
thereon an apartment complex of 230 units, under Section 221(d)4 of the National
Housing Act. Such projects are regulated by HUD as to rent charges and operating
methods. The regulatory agreement limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Depreciation is computed principally by the straight-line and accelerated
methods over estimated useful lives of 3 to 40 years.
 
  Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents except for imprest
balances of petty cash.
 
  Income Taxes
 
     Income taxes have not been recorded in the accompanying financial
statements because they accrue directly to the partners.
 
  Management Agreement
 
     The Partnership pays management fees equal to 7.5 percent of gross
collections to Insignia Management Group.
 
  Financial Accounting Standards Statement No. 107 Disclosures
 
     The carrying amounts reported in the balance sheet, for those financial
instruments described in the schedule of funds in financial institutions
included in the supporting data required by HUD listed on the contents page,
approximate those assets' fair value. Payment of long-term liabilities are
generally dependent upon the Partnership's ability to achieve cash flow, the
partners providing additional funds, the sale of the project or refinancing of
the mortgage at the end of the Regulatory Agreement. Management believes that
estimating the fair value of these long-term liabilities is either not
appropriate or, because of excess costs, considers estimation of fair value to
otherwise be impracticable.
 
  Long-Lived Assets
 
     During 1996, the Partnership adopted FASB Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", which requires impairment losses to be recognized for long-lived assets
used in operations when indictors of impairment are present and the undiscounted
cash flows are not sufficient to recover the assets' carrying amount. The
impairment loss is measured by comparing the fair value of the asset to its
carrying amount. The adoption of FASB No. 121 did not have a material effect on
the Partnership's financial statements.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2. LONG-TERM DEBT
 
     A mortgage note is payable in monthly installments of $19,528 until August
2014, including interest at 7%, to USGI, Inc. The note is collateralized by
pledge of land and buildings and, in addition, is insured by HUD. The note was
confirmed in writing to our independent public accountants. Principal maturities
for the next five years are as follows:

     During the year, the Partnership incurred net interest costs on the
mortgage note of $168,192 and paid net interest costs of $168,576.

4. EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The General Partners
Shannon Manor Apartments, A Limited Partnership
 
     We have audited the accompanying balance sheet of Shannon Manor Apartments,
A Limited Partnership (FHA Project No. 053-35064-PM) as of December 31, 1995 and
the related statements of profit and loss, changes in deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Shannon Manor Apartments, A
Limited Partnership at December 31, 1995, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The Partnership is organized as a limited partnership formed to acquire an
interest in real property located in Durham, North Carolina and to operate
thereon an apartment complex of 230 units, under Section 221(d)4 of the National
Housing Act. Such projects are regulated by HUD as to rent charges and operating
methods. The regulatory agreement limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Depreciation is computed principally by the straight-line and accelerated
methods over estimated useful lives of 3 to 40 years.
 
  Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents except for imprest
balances of petty cash.
 
  Income Taxes
 
     Income taxes have not been recorded in the accompanying financial
statements because they accrue directly to the partners.
 
  Management Agreement
 
     The Partnership pays management fees equal to 7.5 percent of gross
collections to a wholly-owned subsidiary of Insignia Financial Group, Inc.
 
  Financial Accounting Standards Statement No. 107 Disclosures
 
     The carrying amounts reported in the balance sheet, for those financial
instruments described in the schedule of funds in financial institutions
included in the supporting data required by HUD listed on the contents page,
approximate those assets' fair value. Payment of long-term liabilities are
generally dependent upon the Partnership's ability to achieve cash flow, the
partners providing additional funds, the sale of the project or refinancing of
the mortgage at the end of the Regulatory Agreement. Management believes that
estimating the fair value of these long-term liabilities is either not
appropriate or, because of excess costs, considers estimation of fair value to
otherwise be impracticable.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3565
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3566
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Sharon Woods, L.P. For each unit that you tender, you may choose to receive
                    of our Tax-Deferral      % Partnership Preferred Units (also
     referred to as "Preferred OP Units"),                of our Tax-Deferral
     Partnership Common Units (also referred to as "Common OP Units"), or
     $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3571
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3572
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,853.93 per unit for the year
     ended December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $          per year on the number of
     Tax-Deferral      % Preferred OP Units, or distributions of $          per
     year on the number of Tax-Deferral Common OP Units, that you would receive
     in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   3574
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United

THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or

RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3577
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   3578
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   3579
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   3580
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   3581
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 2.25% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   3582
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an

and your partners with an opportunity to liquidate your current investment and
to invest in our operating partnership or receive cash, or to retain your units.
 
     Fractional OP Units. We will issue fractional Tax-Deferral Common OP Units
or Tax-Deferral      % Preferred OP Units, if necessary.

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:

     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will also pay all costs and expenses of printing and mailing
this Prospectus Supplement and the legal fees and expenses in connection
therewith. We will pay the fees of Stanger for providing the fairness opinions
for the offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   3585
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in
 
                                      S-17

its opinion, Stanger concluded that our offer consideration is fair to you from
a financial point of view. COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO
OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $5,800
annually from your partnership and may receive reimbursement for expenses
generated in its capacity as general partner. The property manager received
management fees of $78,000 in 1996, $83,000 in 1997 and $42,065 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. Sharon Woods, L.P. is a Delaware limited
partnership which was formed on June 28, 1985 for the purpose of owning and
operating a single apartment property located in Sharonville, Ohio, known as
"Timber Ridge Apartments." In 1985, it completed a private placement of units
that raised net proceeds of approximately $2,889,000. Timber Ridge Apartments
consists of 248 apartment units. Your partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on July 1, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $5,154,711, payable to FNMA, which bears
interest at a rate of 7.83%. The mortgage debt is due in October 2003. Your
partnership also has a second mortgage note outstanding of $168,300, on the same
terms as the first mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

(a)  Pro forma cash provided by operating activities represents net income, plus

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December

     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer price from a financial
point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3596
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   3597
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the year ended December 31, 1997 were $3,853.93 per unit. This is
equivalent to distributions of $          per year on the number of Tax-Deferral
     % Preferred OP Units, or distributions of $          per year on the number
of Tax-Deferral Common OP Units, that you would receive in an exchange for each
of your partnership's units. Therefore, distributions with respect to the
Preferred OP Units and Common OP Units that we are offering are expected to be
       , immediately following our offer, than the distributions with respect to
your units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 2.25%% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   3599
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   3600
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   3602
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   3603
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   3604
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   3605
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
                                      S-36
<PAGE>   3606
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   3607
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

payment and paid for) pursuant to the offer, any of the following shall occur:
 
        (a) any change (or any condition, event or development involving a
     prospective change) shall have occurred or been threatened in the business,

     contract, or results of operations or prospects of your partnership or
     local markets in which your partnership owns or operates its property,
     including any fire, flood, natural disaster, casualty loss, or act of God
     that, in the sole judgment of the AIMCO Operating Partnership, is or may be
     materially adverse to your partnership or the value of your units to the
     AIMCO Operating Partnership, or the AIMCO Operating Partnership shall have
     become aware of any facts relating to your partnership, its indebtedness or
     its operations which, in the sole judgment of the AIMCO Operating
     Partnership, has or may have material significance with respect to the
     value of your partnership or the value of your units to the AIMCO Operating
     Partnership; or
 
          (b) there shall have occurred (i) any general suspension of trading
     in, or limitation on prices for, securities on any national securities

        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   3610
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   3612
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   3613
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   3614
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             of Class I Preferred Stock. The redemption price for

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   3620
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   3621
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value, the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   3623
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   3624
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the year ended December 31, 1997 were $3,853.93 per unit. This is
     equivalent to distributions of $          per year on the number of
     Tax-Deferral      % Preferred OP Units, or distributions of $          per
     year on the number of Tax-Deferral Common OP Units, that you would receive
     in an exchange for each of your partnership's units. Therefore,
     distributions with respect to the Preferred OP Units and Common OP Units
     that we are offering are expected to be        , immediately following our
     offer, than the distributions with respect to your units. See "Comparison
     of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   3625
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $5,800
annually and may receive reimbursement for expenses generated in its capacity as
general partner and other fees for additional services from your partnership.
The property manager received management fees of $78,000 in 1996, $83,000 in
1997 and $42,065 for the first six months of 1998. The AIMCO Operating
Partnership has no current intention of changing the fee structure for the
manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Sharon Woods, L.P. is a Delaware limited partnership which raised net
proceeds of approximately $2,889,000 in 1985 through a private offering. The
promoter for the private offering of your partnership was Freeman Properties,
Inc. Insignia acquired your partnership in December 1991. AIMCO acquired
Insignia in October, 1998. There are currently a total of 57 limited partners of
your partnership and a total of 44.5 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on June 28, 1985 for the purpose of owning and
operating a single apartment property located in Sharonville, Ohio, known as
"Timber Ridge Apartments." Your partnership's property consists of 248 apartment
units. Your partnership's property had an average occupancy rate of
approximately 91.94% in 1996 and 91.94% in 1997. The average annual rent per
apartment unit is approximately $6,107.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $78,000, $83,000 and $42,065, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on July 1, 2015 unless
earlier dissolved. Your partnership has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $5,154,711, payable to FNMA, which bears interest at a rate of
7.83%. The mortgage debt is due in October 2003. Your partnership also has a
second mortgage note outstanding of $168,300, on the same terms as the first
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

$809,454 for the six months ended June 30, 1998, compared to $814,896 for the

six months ended June 30, 1998, compared to $353,700 for the six months ended
June 30, 1997, an increase of $45,413 or 12.84%. The increase is primarily due
to a non-capitalizable property improvements. Management expenses totaled 42,065

ended June 30, 1998 compared to $17,940 for the six months ended June 30, 1997,

costs, totaled $209,222 for the six months ended June 30, 1998, compared to

31, 1996
 
     Net Income
 
     Your partnership recognized net income of $30,000 for the year ended
December 31, 1997, compared to a net loss of $68,000 for the year ended December

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $323,874 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership and
their affiliates are not liable, responsible or accountable, in damages or
otherwise to your partnership or any limited partner for any acts performed by
any of them which are reasonably believed by them to be within the scope of the
authority conferred on them by your partnership's agreement of limited
partnership and which in good faith, they believed to be in the best interests
of your partnership, excepting only acts of malfeasance, gross negligence or
actual misrepresentation. As a result, unitholders might have a more limited
right of action in certain circumstances than they would have in the absence of
such a provision in your partnership's agreement of limited partnership. The
general partner of your partnership is owned by AIMCO. See "Conflicts of
Interest".
 
     The general partners and their affiliates are entitled to indemnification
by your partnership for any and all acts performed by them in the good faith
belief that the act or omission was in the best interests of your partnership
and which are reasonably within the scope of the authority conferred upon them
by your partnership's agreement of limited partnership or by your partnership,
excepting only acts of malfeasance, gross negligence or actual
misrepresentation; provided, however, that such indemnity will be paid out of
and only to the extent of partnership assets.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The

</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or
 
                                      S-77
<PAGE>   3647
 
maintain information regarding the prices at which secondary sale transactions
in the units have been effectuated. The general partner of your partnership
estimates, based solely on the transfer records of your partnership (or your
partnership's transfer agent), that there have been no units transferred in sale
transactions (excluding transactions believed to be between related parties,
family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     AIMCO currently owns a 2.25% limited partnership interest in your
partnership. Except as described above, neither AIMCO, nor, to the best of its
knowledge, any of its affiliates, (i) beneficially own or have a right to
acquire any units, (ii) have effected any transaction in the units, or (iii)
have any contract, arrangement, understanding or relationship with any other
person with respect to any securities of your partnership, including, but not
limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Sharon Woods, L.P. as of
June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with the accounting basis for federal income tax
reporting. Accordingly, they do not include all the information and footnotes
required by the accounting basis for federal income tax reporting for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Sharon Woods, L. P.
(A Delaware Limited Partnership)
 
     We have audited the accompanying consolidated balance sheet of Sharon
Woods, L.P. (A Delaware Limited Partnership) as of December 31, 1997 and the
related consolidated statements of operations, changes in partners' capital and
cash flows for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Sharon Woods,
L.P., at December 31, 1997 and the consolidated results of its operations and
cash flows for the year then ended in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The limited partnership was organized for the purpose of acquiring, owning
and operating the Timber Ridge Apartments in Sharonville, Ohio. Forty-five units
of limited partnership interests, an individual general partner interest, a
limited partnership general partner interest, and a corporate general partner
interest were issued. The Partnership shall terminate on July 1, 2015, unless
terminated sooner, pursuant to the agreement.
 
  Principles of Consolidation
 
     The financial statements include the accounts of the Partnership and its
majority owned partnerships. All significant interpartnership balances have been
eliminated. Minority interest is immaterial and not shown separately in the
financial statements.
 
  Investment Property
 
     Investment property is stated at cost. Acquisition fees are capitalized as
a cost of real estate. The Partnership records impairment losses on long-lived
assets used in operations when events and circumstances indicated that the
assets might be impaired and the undiscounted cash flows estimated to be
generated by those assets are less than the carrying amounts of those assets. No
adjustments for impairment of value were necessary for the year ended December
31, 1997.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Risks and Uncertainties
 
     The real estate business is highly competitive. The Partnership's real
property investments are subject to competition from similar types of properties
in the vicinities in which they are located and the Partnership is not a
significant factor in its industry. In addition, various limited partnerships
have been formed by related parties to engage in business which may be
competitive with the Partnership.
 
  Cash and Cash Equivalents
 
     Cash on hand and in banks, and money market funds and certificates of
deposit with original maturities of three months or less are considered to be
unrestricted cash. At certain times, the amount of cash deposited at a bank may
exceed the limit on insured deposits.
 
  Fair Value of Financial Instruments
 
     The Partnership believes that the carrying amount of its financial
instruments (except for long term debt) approximates their fair value due to the
short term maturity of these instruments. The fair value of the Partnership's
long-term debt, after discounting the scheduled loan payments at an estimated
borrowing rate currently available to the Partnership approximates its carrying
value.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Loan Costs
 
     Loan costs of approximately $258,000 incurred with the financing of
long-term debt are amortized on a straight-line basis over the life of the debt.
Accumulated amortization is approximately $107,000 at December 31, 1997. These
costs are included in "Other Assets".
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits." Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit and the tenant is current on its rental payments.
 
  Partnership Allocations
 
     Net income or losses are allocated 88.92% to the limited partners and
11.08% to the general partners in accordance with the partnership agreement.
Distributions of available cash (cash-flow) or proceeds from financing or sale
of the property are allocated among the limited and general partners in
accordance with the partnership agreement.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less. Rental revenue is recognized as earned.
 
  Advertising Costs
 
     The Partnership expenses the costs of advertising as incurred.
 
  Depreciation
 
     Building and improvements are depreciated using the straight-line method
over the estimated useful lives of the assets, ranging from 5 to 30 years.
 
  Restricted Escrows
 
     Restricted escrows consist of funds established to cover necessary repairs
and replacements of existing improvements at the property. The balance in the
restricted escrow account at December 31, 1997 was approximately $108,000.

NOTE C -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     In January 1991, the Partnership entered into a management contract with
Insignia Management Group, an affiliate of Insignia Financial Group, Inc.,
("Insignia") who is an affiliate of the managing general partner of Sharon
Woods, L.P. As a result, affiliates of Insignia now provide property management
and asset management services to the Partnership.
 
     The following items were incurred with Insignia and its affiliates in 1997
(in thousands):

Reimbursement for investor services, asset management and

</TABLE>
 
     For the period of January 1, 1997, to August 31, 1997, the Partnership
insured its property under a master policy through an agency and insurer
unaffiliated with the Managing General Partner. An affiliate of the Managing
General Partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the master policy. The agent assumed the financial obligations to the
affiliate of the Managing General Partner who received payments on these
obligations from the agent. The amount of the Partnership's insurance premiums
that accrued to the benefit of the affiliate of the Managing General Partner by
virtue of the agent's obligations was not significant.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Insignia entered into an Agreement and Plan of Merger, dated as of May 26,
1998, (as subsequently amended and restated, the "Merger Agreement") with
Apartment Investment and Management Company ("AIMCO"), pursuant to which
Insignia will merge its national residential property management operations and
its controlling interest in Insignia Properties Trust with and into AIMCO, with
AIMCO as the survivor. Consummation of the Merger, which is anticipated to occur
in the third quarter of 1998, is subject to certain conditions, including the
approval of the stockholders of Insignia (but not the approval of the
stockholders of AIMCO). If the closing occurs, AIMCO will then control the
General Partner of the Partnership.

NOTE F -- YEAR 2000 (UNAUDITED)
 
     The Partnership is dependent upon the General Partner and Insignia for
management and administrative services. Insignia has completed an assessment and
will have to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter (the "Year 2000 Issue"). The project is estimated to be completed not
later than December 31, 1998, which is prior to any anticipated impact on its
operating systems. The General Partner believes that with modifications to
existing software and conversions to new software, the Year 2000 Issue will not
pose significant operational problems for its computer systems. However, if such
modifications and conversions are not made, or are not completed timely, the
Year 2000 Issue could have a material impact on the operations of the
Partnership.
 
NOTE G -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Sharon Woods, L. P.
(A Delaware Limited Partnership)
 
     We have audited the accompanying consolidated statement of assets,
liabilities and partners' equity -- Federal income tax basis of Sharon Woods,
L. P. (A Delaware Limited Partnership) as of December 31, 1997 and the related
consolidated statements of revenues and expenses -- Federal income tax basis,
changes in partners' equity -- Federal income tax basis and cash flow -- Federal
income tax basis for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note A, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated assets, liabilities and partners'
equity of Sharon Woods, L. P., at December 31, 1997 and its consolidated
revenues and expenses, changes in partners' equity and cash flow for the year
then ended, on the basis of accounting described in Note A.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The limited partnership was organized for the purpose of acquiring, owning
and operating the Timber Ridge Apartments in Sharonville, Ohio. Forty-five units
of limited partnership interests, an individual general partner interest, a
limited partnership general partner interest, and a corporate general partner
interest were issued. The Partnership shall terminate on July 1, 2015, unless
terminated sooner, pursuant to the agreement.
 
  Basis of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets and recognition and amortization of
syndication costs.
 
  Principles of Consolidation
 
     The financial statements include the accounts of the Partnership and its
majority owned partnerships. All significant interpartnership balances have been
eliminated. Minority interest is immaterial and not shown separately in the
financial statements.
 
  Apartment Properties
 
     Apartment properties are stated at cost. Depreciation is provided by the
modified accelerated cost recovery system (MACRS) for 27.5 year residential
property.
 
  Loan Costs
 
     Loan costs of approximately $258,000 incurred with the financing of
long-term debt are amortized on a straight-line basis over the life of the debt.
Accumulated amortization is approximately $107,000 at December 31, 1997. These
costs are included in "Other Assets".
 
  Partnership Allocations
 
     Subject to possible adjustments required under Section 704(b) of the
Internal Revenue Service Code, net earnings (loss) are allocated 88.92% to the
limited partners and 11.08% to the general partners in accordance with the
partnership agreement. Distributions of available cash (cash flow) or proceeds
from financing or sale of the property are allocated among the limited and
general partners in accordance with the partnership agreement.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determination by taxing authorities.

  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and includes the deposits in "Receivables and deposits".
Deposits are refunded when the tenant vacates the apartment if there has been no
damage.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.
 
  Syndication Costs
 
     Syndication costs of approximately $182,000 are included in "Other assets".
They are stated at cost to the Partnership and are not amortizable for Federal
income tax purposes, but result in a capital loss upon the dissolution of the
Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Sharon Woods, L. P.
(A Delaware Limited Partnership)
 
     We have audited the accompanying consolidated statement of assets,
liabilities and partners' equity -- Federal income tax basis of Sharon Woods, L.
P. (A Delaware Limited Partnership) as of December 31, 1996 and the related
consolidated statements of revenues and expenses -- Federal income tax basis,
changes in partners' equity -- Federal income tax basis and cash flow -- Federal
income tax basis for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note A, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated assets, liabilities and partners'
equity of Sharon Woods, L. P., as of December 31, 1996 and its consolidated
revenues and expenses, changes in partners' equity and cash flow for the year
then ended, on the basis of accounting described in Note A.

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS --
                            FEDERAL INCOME TAX BASIS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The limited partnership was organized for the purpose of acquiring, owning
and operating the Timber Ridge Apartments in Sharonville, Ohio. Forty-five units
of limited partnership interests, an individual general partner interest, a
limited partnership general partner interest, and a corporate general partner
interest were issued. The Partnership shall terminate on July 1, 2015, unless
terminated sooner, pursuant to the agreement.
 
  Basis of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets and recognition and amortization of
syndication costs.
 
  Principles of Consolidation
 
     The financial statements include the accounts of the Partnership and its
majority owned partnerships. All significant interpartnership balances have been
eliminated. Minority interest is immaterial and not shown separately in the
financial statements.
 
  Apartment Properties
 
     Apartment properties are stated at cost. Depreciation is provided by the
modified accelerated cost recovery system (MACRS) for 27.5 year residential
property.
 
  Loan Costs
 
     Loan costs of approximately $258,000 incurred with the financing of
long-term debt are amortized on a straight-line basis over the life of the debt.
Accumulated amortization is approximately $81,000 at December 31, 1996.
 
  Partnership Allocations
 
     Subject to possible adjustments required under Section 704(b) of the
Internal Revenue Service Code, net earnings (loss) are allocated 88.92% to the
limited partners and 11.08% to the general partners in accordance with the
partnership agreement. Distributions of available cash (cash flow) or proceeds
from financing or sale of the property are allocated among the limited and
general partners in accordance with the partnership agreement.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying

interpretations, amounts reported in the financial statements could be changed
at a later date upon final determination by taxing authorities.
 
  Cash and Cash Equivalents -- Unrestricted Cash
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and considers the deposits to be restricted cash. Deposits
are refunded when the tenant vacates the apartment if there has been no damage.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Sharon Woods, L. P.
(A Delaware Limited Partnership)
 
     We have audited the accompanying statement of assets, liabilities and
partners' equity -- Federal income tax basis of Sharon Woods, L. P. (A Delaware
Limited Partnership) as of December 31, 1995 and the related statements of
revenues and expenses -- Federal income tax basis, changes in partners'
equity -- Federal income tax basis and cash flow -- Federal income tax basis for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Partnership's management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     As more fully described in Note 1, these financial statements have been
prepared on the accounting basis used for Federal income tax purposes which is a
comprehensive basis of accounting other than generally accepted accounting
principles.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets, liabilities and partners' equity of Sharon
Woods, L. P., as of December 31, 1995 and its revenues and expenses, its changes
in partners' equity and its cash flow for the year then ended, on the basis of
accounting described in Note 1.

                               DECEMBER 31, 1995
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     The limited partnership was organized for the purpose of acquiring, owning
and operating the Timber Ridge Apartments in Sharonville, Ohio. Forty-five units
of limited partnership interests, an individual general partner interest, a
limited partnership general partner interest, and a corporate general partner
interest were issued. The Partnership shall terminate on July 1, 2015, unless
terminated sooner, pursuant to the agreement.
 
  Basis of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally accepted
accounting principles primarily in the timing of recognition of revenue and
certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets and recognition and amortization of
syndication costs.
 
  Apartment Properties
 
     Apartment properties are stated at cost. Depreciation is provided by the
modified accelerated cost recovery system (MACRS) for 27.5 year residential
property.
 
  Loan Costs
 
     Loan costs incurred with the financing of long-term debt are amortized on a
straight-line basis over the life of the debt.
 
  Partnership Allocations
 
     Subject to possible adjustments required under Section 704(b) of the
Internal Revenue Service Code, net earnings (loss) are allocated 88.92% to the
limited partners and 11.08% to the general partners in accordance with the
partnership agreement. Distributions of available cash (cash flow) or proceeds
from financing or sale of the property are allocated among the limited and
general partners in accordance with the partnership agreement.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determination by taxing authorities.
 
  Cash
 
     The Partnership considers only unrestricted cash and tenant security
deposits to be cash. At certain times, the amount of cash deposited at a bank
may exceed the limit on insured deposits.

    NOTES TO FINANCIAL STATEMENTS -- FEDERAL INCOME TAX BASIS -- (CONTINUED)
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
2. MORTGAGE NOTES PAYABLE
 
     Mortgage notes payable consist of the following:

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3689
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3690
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Snowden Village Associates, L.P. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3695
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3696
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,375 per unit for the six months
     ended June 30, 1998 (equivalent to $6,750 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   3698
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of

     for liquidity, other financial opportunities available to you and your tax
     position.

     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3701
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   3702
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   3703
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   3704
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   3705
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least 51% of the units of your partnership. In
     the absence of such consent, your only option for liquidation of your
     investment would be to sell your units in a private transaction. Any such
     sale could be at a very substantial discount from your pro rata share of
     the fair market value of your partnership's property and might involve
     significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   3706
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We

services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   3711
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity from your partnership. The
property manager received management fees of $82,069 in 1996, $82,982 in 1997
and $21,144 for the first six months of 1998. We have no current intention of
changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Snowden Village Associates, L.P. is a
Delaware limited partnership which was formed on June 21, 1985 for the purpose
of owning and operating a single apartment property located in Fredericksburg,
Virginia, known as "Snowden Village Apartments I" and "Snowden Village
Apartments II". In 1985, it completed a private placement of units that raised
net proceeds of approximately $2,745,000. Snowden Village Apartments I consists
of 132 apartment units and Snowden Village Apartments II consists of 122
apartment units. Your partnership has no employees.
 
                                      S-18
<PAGE>   3712
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2020, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding on "Snowden Village Apartments I" of
$2,513,592 payable to Maine Midland Bank and Bank of America, which bears
interest at a rate of 7.60%. Such mortgage debt is due November 2002. There is
also a mortgage note on "Snowden Village Apartments II," the balance of which is
$2,692,677, as of June 30, 1998. The note is payable to WMF Huntoon Page, bears
interest at 7.50% and is due September 2020. Your partnership's agreement of
limited partnership also allows your general partner to lend funds to your
partnership. Currently, the general partner of your partnership has no loans
outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3720
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   3721
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $3,375 per unit (equivalent to
$6,750 on an annualized basis). This is equivalent to distributions of $  per
year on the number of Tax-Deferral   % Preferred OP Units, or distributions of
$  per year on the number of Tax-Deferral Common OP Units, that you would
receive in an exchange for each of your partnership's units. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   3723
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 51% of the units of your partnership. In the absence
of such consent, your only option for liquidation would be to sell your units in
a private transaction. Any such sale likely would be at a very substantial
discount from your pro rata share of the fair market value of your partnership's
property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   3724
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the
       Tax-Deferral Common OP Units have been equivalent to the dividends paid
       on AIMCO's Class A Common Stock. We expect this to continue in the
       future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   3726
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   3727
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   3728
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   3729
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, by increasing or decreasing the number of Preferred OP Units or
Common OP Units, or the amount of cash, offered, eliminating any of the
alternative types of consideration being offered, or increasing or decreasing
the percentage of outstanding units being sought). Notice of any such extension,
termination or amendment will promptly be disseminated in a manner reasonably
designed to inform unitholders of such change. In the case of an extension of
the offer, the extension will be followed by a press release or public
announcement which will be issued no later than 9:00 a.m., Denver, Colorado
time, on the next business day after the scheduled expiration date of the offer,
in accordance with Rule 14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.

     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     that any debt of your partnership or any of its subsidiaries secured by any

        (f) a tender or exchange offer for any units shall have been commenced

circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely
 
                                      S-40
<PAGE>   3734
 
     affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to your partnership's business, or that certain
parts of your partnership's business might not have to be disposed of or other
substantial conditions complied with in order to obtain such approval or action,
any of which could cause the AIMCO Operating Partnership to elect to terminate
the offer without purchasing units hereunder. The AIMCO Operating Partnership's
obligation to purchase and pay for units is subject to certain conditions,
including conditions related to the legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   3736
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   3737
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   3739
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   3744
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   3745
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   3747
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   3748
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $3,375 per unit (equivalent to
     $6,750 on an annualized basis). This is equivalent to distributions of $
     per year on the number of Tax-Deferral   % Preferred OP Units, or
     distributions of $  per year on the number of Tax-Deferral Common OP Units,
     that you would receive in exchange for each of your partnership's units.
     Therefore, distributions with respect to the Preferred OP Units and Common
     OP Units that we are offering are expected to be        , immediately
     following our offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   3749
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   3753
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partners but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $82,069 in 1996, $82,982 in 1997 and $21,144 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Snowden Village Associates, L.P. is a Delaware limited partnership which
raised net proceeds of approximately $2,745,000 in 1985 through a private
offering. The promoter for the private offering of your partnership was
Jacques-Miller. Insignia acquired your partnership in December 1991. AIMCO
acquired Insignia in October, 1998. There are currently a total of 73 limited
partners of your partnership and a total of 44 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the single
apartment property described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on June 21, 1985 for the purpose of owning and
operating a single apartment property located in Fredericksburg, Virginia, known
as "Snowden Village Apartments I" and "Snowden Village Apartments II." "Snowden
Village Apartments I" consists of 132 apartment units. There are 52 one-bedroom
apartments and 80 two-bedroom apartments. The total rentable square footage is
116,568 square feet. The average annual rent per apartment unit is $5,975. In
both 1996 and 1997, the average occupancy rate was 96.97%. There are 132
apartment units in "Snowden Village Apartments II." The total rentable square
footage is 93,660 square feet and the average annual rent per apartment unit is
$5,829. The average occupancy rate for 1996 and 1997 was 91.80%.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your

INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2020
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES

Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your

ownership of the partnership's property and management and leasing business,

six months ended June 30, 1997, an increase of $138,040, or 17.20%. This was
primarily a result of a increased occupancy due to management's increased
efforts and incentives offered to boost leasing traffic.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $348,850 for the

June 30, 1997, an increase of $8,561 or 2.52%. Management expenses totaled
$21,144 for the six months ended June 30, 1998, compared to $19,027 for the six
months ended June 30, 1997, a increase of $2,117, or 11.13%. The increase
resulted from a increase in rental revenues as management fees are calculated
based on a percentage of revenues.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $30,966 for the six months
ended June 30, 1998 compared to $23,147 for the six months ended June 30, 1997,

asset management fees, taxes and licences, and general partner reimbursement
fees.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $208,050 for the six months ended June 30, 1998, compared to

31, 1996

result of an increase in maintenance expenses at both properties and an increase
in property administration expenses. Management expenses totaled $82,982 for the
year ended December 31, 1997, compared to $82,069 for the year ended December

operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership is not
liable to your partnership or any limited partner for any acts or failures to do
any act performed by it in the absence of its willful malfeasance or gross
negligence. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership's agreement of limited partnership does not provide for
indemnification of the general partners by your partnership for any acts or
omissions performed by them.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The

</TABLE>
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).

BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Snowden Village
Associates, L. P. as of June 30, 1998 and for the six months ended June 30, 1998
and 1997 have been prepared in accordance with the accounting basis for Federal
income tax reporting. Accordingly, they do not include all the information and
footnotes required by the accounting basis for Federal income tax reporting for
complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                         REPORT OF INDEPENDENT AUDITORS
 
The Partners
Snowden Village Associates, L. P.
 
     We have audited the accompanying balance sheet of Snowden Village
Associates, L. P. as of December 31, 1997, and the related statements of
operations, partners' deficit and cash flows for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Snowden Village Associates,
L. P. at December 31, 1997, and the results of its operations and cash flows for
the year then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE A -- SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Snowden Village Associates, L. P. (the "Partnership") is a Delaware limited
partnership which began operations in 1985 with the purchase of property and
improvements in Fredericksburg, Virginia, presently operating as two apartment
complexes. The two projects consist of Phase I, a conventional apartment
complex, and Phase II, a complex regulated under Section 221(d)4 of the National
Housing Act. The general partners of the Partnership are Jacques Miller
Associates and Jacques Miller, Inc. (collectively, the "General Partners").
 
  Investment Property
 
     The investment property is stated at cost. Acquisition fees are capitalized
as a cost of real estate. The Partnership records impairment losses on
long-lived assets used in operations when events and circumstances indicate that
the assets might be impaired and the undiscounted cash flows estimated to be
generated by those assets are less than the carrying amounts of those assets. No
adjustments for impairment of value were necessary for the year ended December
31, 1997.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Risks/Uncertainties
 
     The real estate business is highly competitive. The Partnership's real
property investments are subject to competition from similar types of properties
in the vicinities in which they are located and the Partnership is not a
significant factor in its industry. In addition, various limited partnerships
have been formed by related parties to engage in business which may be
competitive with the Partnership.
 
  Cash and Cash Equivalents
 
     Cash on hand and in banks, and money market funds and certificates of
deposit with original maturities of three months or less are considered to be
unrestricted cash. At certain times, the amount of cash deposited at a bank may
exceed the limit on insured deposits.
 
  Tenant Security Deposits
 
     Tenant security deposits required from lessees for the duration of the
lease as required by the Partnership are included in receivables and deposits.
These deposits are refunded when the tenant vacates, provided the tenant has not
damaged its space and is current on its rental payments.
 
  Fair Value
 
     The Partnership believes that the carrying amount of its financial
instruments (except for long term debt) approximates their fair value due to the
short term maturity of these instruments. The fair value of the Partnership's
long term debt, after discounting the scheduled loan payments at an estimated
borrowing rate currently available to the Partnership, approximates its carrying
value.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Loan Costs
 
     Loan costs of approximately $63,000, net of accumulated amortization of
approximately $64,000, are being amortized on a straight-line basis over the
life of the loan. Unamortized loan costs are included in deferred charges.
 
  Partnership Allocations
 
     Net earnings or loss, distributions to partners, and taxable income or loss
are allocated to the partners in accordance with the partnership agreement.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less. Rental revenue is recognized as earned.
 
  Advertising Costs
 
     Advertising costs of approximately $34,000 in 1997 were charged to expense
as incurred and are included in operating expenses.
 
  Depreciation
 
     Building and improvements are depreciated using the straight-line method
over the estimated useful lives of the assets, ranging from 4 to 25 years.
 
  Restricted Escrows
 
     Restricted escrows consist of funds established to cover necessary repairs
and replacements of existing improvements at the property. The balance in the
restricted escrow account at December 31, 1997 was approximately $193,000.
 
  Income Taxes
 
     No provision has been made for Federal and state income taxes since such
taxes are the personal responsibility of the partners.

     The Partnership exercised interest rate buy-downs when one of its mortgages
was refinanced, reducing the stated rate from 8.76% to 7.60%. The fee for the
interest rate reduction amounted to $207,221 and is being amortized as a loan
discount on the interest method over the life of the loans. The discount fee is
reflected as a reduction of the mortgage notes payable and increases the
effective rate of the debt to 8.76%.
 
     Scheduled principal payments of mortgage notes payable subsequent to
December 31 are as follows (in thousands):

NOTE D -- RELATED PARTY TRANSACTIONS
 
     The Partnership has no employees and is dependent on the General Partners
and affiliates of Insignia Financial Group, Inc. ("Insignia") for the management
and administration of all of the Partnership activities, as provided in the
Partnership Agreement. Affiliates of Insignia have ownership interests in the
General Partners, with certain affiliates of Insignia providing property
management and asset management services to the Partnership. The Partnership
Agreement provides for payments to affiliates for services and as reimbursement
of certain expenses incurred by affiliates on behalf of the Partnership. The
following transactions occurred with the General Partners and affiliates during
the year (in thousands):
 
<TABLE>

</TABLE>
 
     On September 6, 1997, an affiliate of the General Partners purchased Lehman
Brothers' Class "D" subordinated bonds of SASCO, 1992-M1. These bonds are
secured by 55 multi-family apartment mortgage loan pairs held in Trust,
including Snowden Village Phase I owned by the Partnership.
 
     For the period January 1, 1996 to August 31, 1997 the Partnership insured
its property under a master policy through an agency and insurer unaffiliated
with Insignia. An affiliate of Insignia acquired, in the acquisition of a
business, certain financial obligations from an insurance agency which was later
acquired by the agent who placed the master policy. The agent assumed the
financial obligations to the affiliate of Insignia who receives payment on these
obligations from the agent. The amount of the Partnership's insurance premiums
accruing to the benefit of the affiliate of Insignia by virtue of the agent's
obligations is not significant.
 
     Insignia entered into an Agreement and Plan of Merger, dated as of May 26,
1998, (as subsequently amended and restated, the "Merger Agreement") with
Apartment Investment and Management Company ("AIMCO"), pursuant to which
Insignia will merge its national residential property management operations and
its controlling interest in Insignia Properties Trust with and into AIMCO, with
AIMCO as the survivor. Consummation of the Merger, which is anticipated to occur
in the third quarter of 1998, is subject to certain conditions, including the
approval of the stockholders of Insignia (but not the approval of the
stockholders of AIMCO). If the closing occurs, AIMCO will then control the
General Partner of the Partnership.

NOTE F -- YEAR 2000 (UNAUDITED)
 
     The Partnership is dependent upon the General Partner and Insignia for
management and administrative services. Insignia has completed an assessment and
will have to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter (the "Year 2000 Issue"). The project is estimated to be completed not
later than December 31, 1998, which is prior to any anticipated impact on its
operating systems. The General Partner believes that with modifications to
existing software and conversions to new software, the Year 2000 Issue will not
pose significant operational problems for its computer systems. However, if such
modifications and conversions are not made, or are not completed timely, the
Year 2000 Issue could have a material impact on the operations of the
Partnership.
 
NOTE G -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                               DECEMBER 31, 1996
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Snowden Village Associates, L. P. is a Delaware limited partnership which
began operations in 1985 with the purchase of property and improvements in
Fredericksburg, Virginia, presently operating as two apartment complexes. The
two projects consist of Phase I, a conventional apartment complex, and Phase II,
a complex regulated under Section 221(d)4 of the National Housing Act. The
regulatory agreement for Phase II limits annual distributions of net operating
receipts to "surplus cash" available at the end of each year.
 
  Depreciation
 
     Property and improvements are recorded at the Partnership's acquisition
cost. Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over estimated service lives, using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for Federal and state income taxes since such
taxes are the personal responsibility of the partners.
 
  Partnership Allocations
 
     Net earnings or loss and taxable income or loss are allocated 99% to the
limited partners and 1% to the general partner. Distributions of available cash
or proceeds from financing or sale of the property are allocated among the
limited partners and the general partners in accordance with the limited
partnership agreement.
 
  Cash Equivalents
 
     It is the Partnership's policy to classify all liquid short-term
investments with a maturity of three months or less as cash equivalents.
 
  Management Agreements
 
     The Projects pay management fees equal to 5 percent of gross collections to
Insignia Management Group.
 
  Financial Accounting Standards Statement No. 107 Disclosures
 
     The carrying amounts reported in the balance sheet for cash and reserve
escrows approximate those assets' fair value. Payment of long-term liabilities
are generally dependent upon the Partnership's ability to achieve cash flow, the
partners providing additional funds, the sale of the project or refinancing of
the mortgages at the end of their terms. Management believes that estimating the
fair value of these long-term liabilities is either not appropriate or, because
of excess costs, considers estimation of fair value to otherwise be
impracticable.
 
  Restricted Escrows -- Reserve Accounts
 
     A General Reserve Account was established for one of the apartment
complexes to cover necessary repairs and replacements of existing improvements,
debt service, out-of-pocket expenses incurred for ordinary and necessary
administrative tasks, and payment of real property taxes and insurance premiums.
The Partnership is required to deposit net operating income (as defined in the
mortgage note) from the property to the reserve account until the reserve
account equals $1,000 per apartment unit or $132,000 in total.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)
 
     The Partnership has also established a reserve for replacements in
accordance with the provisions of a regulatory agreement. The restricted cash is
held in a separate bank account to be used for replacements with the approval of
HUD.
 
     At December 31, 1996, there was $133,861 in the General Reserve Account and
$39,355 in the Reserve for Replacements, totaling $173,216.
 
  Present Value Discounts
 
     Periodically, the Partnership incurs debt at below market rates for similar
debt. Present value discounts are recorded on the basis of prevailing market
rates and are amortized on an interest method over the life of the related debt.
 
  Loan Costs
 
     In connection with the refinancing of certain mortgage notes payable in
1992, loan costs of $126,557 were incurred which are being amortized on a
straight-line basis over the life of the loans.
 
  Long-Lived Assets
 
     During 1996, the Partnership adopted FASB Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", which requires impairment losses to be recognized for long-lived assets
used in operations when indictors of impairment are present and the undiscounted
cash flows are not sufficient to recover the assets' carrying amount. The
impairment loss is measured by comparing the fair value of the asset to its
carrying amount. The adoption of FASB No. 121 did not have a material effect on
the Partnership's financial statements.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2. MORTGAGE NOTES PAYABLE

     During the year, net interest costs incurred were $418,041 and interest
paid was $418,296.
 
     The Partnership exercised interest rate buy-downs when one of its mortgages
was refinanced, reducing the stated rate from 8.76% to 7.60%. The fee for the
interest rate reduction amounted to $207,221 and is being amortized as a loan
discount on the interest method over the life of the loans. The discount fee is
reflected as a reduction of the mortgage notes payable and increases the
effective rate of the debt to 8.76%.
 
     Scheduled principal payments of mortgage notes payable subsequent to
December 31 are as follows:

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                               DECEMBER 31, 1995
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Snowden Village Associates, L. P. is a Delaware limited partnership which
began operations in 1985 with the purchase of property and improvements in
Fredericksburg, Virginia, presently operating as two apartment complexes. The
two projects consist of Phase I, a conventional apartment complex, and Phase II,
a complex regulated under Section 221(d)4 of the National Housing Act. The
regulatory agreement limits annual distributions of net operating receipts to
"surplus cash" available at the end of each year.
 
  Depreciation
 
     Property and improvements are recorded at the Partnership's acquisition
cost. Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over estimated service lives, using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for Federal and state income taxes since such
taxes are the personal responsibility of the partners.
 
  Partnership Allocations
 
     Net earnings or loss and taxable income or loss are allocated 99% to the
limited partners and 1% to the general partner. Distributions of available cash
or proceeds from financing or sale of the property are allocated among the
limited partners and the general partners in accordance with the limited
partnership agreement.
 
  Cash Equivalents
 
     It is the Partnership's policy to classify all liquid short-term
investments with a maturity of three months or less as cash equivalents.
 
  Management Agreements
 
     The Projects pay management fees equal to 5 percent of gross collections to
Insignia Management Group.
 
  Financial Accounting Standards Statement No. 107 Disclosures
 
     The carrying amounts reported in the balance sheet for cash and reserve
escrows approximate those assets' fair value. Payment of long-term liabilities
are generally dependent upon the Partnership's ability to achieve cash flow, the
partners providing additional funds, the sale of the project or refinancing of
the mortgages at the end of their terms. Management believes that estimating the
fair value of these long-term liabilities is either not appropriate or, because
of excess costs, considers estimation of fair value to otherwise be
impracticable.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)
 
  Restricted Escrows -- Reserve Accounts
 
     A General Reserve Account was established for one of the apartment
complexes to cover necessary repairs and replacements of existing improvements,
debt service, out-of-pocket expenses incurred for ordinary and necessary
administrative tasks, and payment of real property taxes and insurance premiums.
The Partnership is required to deposit net operating income (as defined in the
mortgage note) from the property to the reserve account until the reserve
account equals $1,000 per apartment unit or $132,000 in total.
 
     The Partnership has also established a reserve for replacements in
accordance with the provisions of a regulatory agreement. The restricted cash is
held in a separate bank account to be used for replacements with the approval of
HUD.
 
     At December 31, 1995, there was $135,045 in the General Reserve Account and
$35,475 in the Reserve for Replacements, totaling $170,520.
 
  Present Value Discounts
 
     Periodically, the Partnership incurs debt at below market rates for similar
debt. Present value discounts are recorded on the basis of prevailing market
rates and are amortized on an interest method over the life of the related debt.
 
  Loan Costs
 
     In connection with the refinancing of certain mortgage notes payable in
1992, loan costs of $126,557 were incurred which are being amortized on a
straight-line basis over the life of the loans.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2. MORTGAGE NOTES PAYABLE
 
     The principal terms of mortgage notes payable are as follows:

     During the year, net interest costs incurred were $426,159 and interest
paid was $426,395.
 
     The Partnership exercised interest rate buy-downs when one of its mortgages
was refinanced, reducing the stated rate from 8.76% to 7.60%. The fee for the
interest rate reduction amounted to $207,221 and is being amortized as a loan
discount on the interest method over the life of the loans. The discount fee is
reflected as a reduction of the mortgage notes payable and increases the
effective rate of the debt to 8.76%.
 
     Scheduled principal payments of mortgage notes payable subsequent to
December 31 are as follows:

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3802
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3803
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Sturbrook Investors, Ltd. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3808
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3809
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $       per unit for the six months
     ended June 30, 1998 (equivalent to $       on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of
     units without the consent of the general partner. Such consent may be
     withheld by the general partner in its sole discretion. The general partner
     may withhold its consent if such transfer would result in the termination
     of your partnership for tax purposes which will occur if more than 50% or
     more of the total interests in your partnership are transferred within a
     12-month period. If we acquire a significant percentage of the interest in
     your partnership, the general partner may not consent to a transfer for a
     12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
     In addition, there is a sale or exchange of 50% or more of the total
     interest in capital and profits of your partnership within any 12-month
     period, including sales or exchanges resulting from the offer, your
     partnership will terminate for Federal income tax purposes. Any such
     termination may, among other things, subject the assets of your partnership
     to longer depreciable lives than those currently applicable to the assets
     of your partnership. This would generally decrease the annual average
     depreciation deductions allocable to you if you do not tender all of your
     units (thereby increasing the taxable income allocable to your units each
     year), but would have no effect on the total depreciation deductions
     available over the useful lives of the assets of your partnership. Any such
     termination may also change (and possibly shorten) your holding period with
     respect to your units that you choose to retain.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF THE OFFER. THIS SUMMARY DOES NOT DISCUSS ALL
     ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN LIGHT OF
     YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
     UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE
     OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX
     SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS
     PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR
     TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE
     OFFER.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.

<PAGE>   3811
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.

<PAGE>   3812
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3814
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns
 
                                       S-8
<PAGE>   3815
 
and manages a single apartment property to an interest in a partnership that
invests in and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
                                       S-9
<PAGE>   3816
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our
 
                                      S-10
<PAGE>   3817
 
investors unless certain financial tests or other criteria are satisfied. In
some cases, our subsidiaries are subject to similar provisions, which may
restrict their ability to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.

<PAGE>   3818
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
                                      S-12
<PAGE>   3819
 
        Continuation of Your Partnership Without the Offer. A second alternative
     would be for your partnership to continue its business without our offer. A
     number of advantages could result from the continued operation of your
     partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private transaction. Any such sale would likely be at a very substantial
     discount from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
                                      S-13
<PAGE>   3820
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the
 
                                      S-17
<PAGE>   3824
 
fairness opinion. Based on its analysis, and subject to the assumptions,
limitations and qualifications cited in its opinion, Stanger concluded that our
offer consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity and fees for additional
services. The property manager received management fees of $68,988 in 1996,
$73,266 in 1997 and $39,322 for the first six months of 1998. We have no current
intention of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. Sturbrook Investors, Ltd. is a
California limited partnership which was formed on October 15, 1981 for the
purpose of owning and operating a single apartment property located in Richmond,
Virginia, known as "Sunrise V". In 1982, it completed a private placement of
units that raised net proceeds of approximately $2,624,800. Sunrise V consists
of 229 apartment units. Your partnership has no employees.
 
     Property Management. Since 1992, your partnership's property has been
managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2031, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $3,912,829, payable to Marine Midland and
Bank of America, which bears interest at a rate of 7.60%. The mortgage debt is
due in November 2002. Your partnership also has a second mortgage note
outstanding of $139,037, which bears interest at 7.60% and is due November 1998.
Your partnership's agreement of limited partnership also allows your general
partner to lend funds to your partnership. Currently, the general partner of
your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period

(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our cash offer consideration,
from a financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3833
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
 
                                      S-27
<PAGE>   3834
 
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or Common OP Units may be
redeemed for shares of Class I Preferred Stock or Class A Common Stock.
Furthermore, the liquidity of the Class I Preferred Stock and the Class A Common
Stock at the time at which OP Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June 30, 1998 were $     per unit (equivalent to
$
on an annualized basis). This is equivalent to distributions of $          per
year on the number of Tax-Deferral      % Preferred OP Units, or distributions
of $          per year on the number of Tax-Deferral Common OP Units, that you
would receive in an exchange for each of your partnership's units. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership
 
                                      S-28
<PAGE>   3835
 
were to be reduced, and you do not tender all of your units pursuant to our
offer, you will be treated as receiving a hypothetical distribution of cash
resulting from a decrease in your share of the liabilities of your partnership.
Any such hypothetical distribution of cash would be treated as a nontaxable
return of capital to the extent of your adjusted tax basis in your units and
thereafter as gain.
 
     POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES.
If there is a sale or exchange of 50% or more of the total interest in capital
and profits of your partnership within any 12-month period, including sales or
exchanges resulting from the offer, your partnership will terminate for Federal
income tax purposes. Any such termination may, among other things, subject the
assets of your partnership to longer depreciable lives than those currently
applicable to the assets of your partnership. This would generally decrease the
annual average depreciation deductions allocable to you if you do not tender all
of your units (thereby increasing the taxable income allocable to your units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership. Any such
termination may also change (and possibly shorten) your holding period with
respect to your units that you choose to retain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of units without the
consent of the general partner. Such consent may be withheld by the general
partner in its sole discretion. The general partner may withhold its consent if
such transfer would result in the termination of your partnership for tax
purposes which will occur if more than 50% or more of the total interests in
your partnership are transferred within a 12-month period. If we acquire a
significant percentage of the interest in your partnership, the general partner
may not consent to a transfer for a 12-month period following the offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
                                      S-29
<PAGE>   3836
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to
 
                                      S-30
<PAGE>   3837
 
continue operating as presently structured, your partnership could be forced to
borrow on terms that could result in net losses from operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
                                      S-31
<PAGE>   3838
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-33
<PAGE>   3840
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-34
<PAGE>   3841
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-36
<PAGE>   3843
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-38
<PAGE>   3845
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

Partnership shall not be required to accept for payment and pay for any units

     Operating Partnership shall have become aware of any facts relating to your
     partnership, its indebtedness or its operations which, in the sole judgment

     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or

<PAGE>   3847
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-41
<PAGE>   3848
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-43
<PAGE>   3850
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-44
<PAGE>   3851
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-46
<PAGE>   3853
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-51
<PAGE>   3858
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-52
<PAGE>   3859
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
CERTAIN TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING UNITHOLDERS
 
     Section 708 of the Code provides that if there is a sale or exchange of 50%
or more of the total interest in capital and profits of a partnership within any
12-month period, such partnership terminates for Federal income tax purposes (a
"Termination"). It is possible that the AIMCO Operating Partnership's
acquisition of units pursuant to the offer could result in a Termination of your
partnership. If a purchase of units results in a Termination, the following
Federal income tax events will be deemed to occur with respect to such
Termination: the terminated Partnership (the "Old Partnership") will be deemed
to have contributed all of its assets (subject to its liabilities) (the
"Hypothetical Contribution") to a new partnership (the "New Partnership") in
exchange for an interest in the New Partnership and, immediately thereafter, the
Old Partnership will be deemed to have distributed interests in the New
Partnership (the "Hypothetical Distribution") to the AIMCO Operating Partnership
and unitholders who do not tender all of their units (a "Remaining Unitholders")
in proportion to their respective interests in the Old Partnership in
liquidation of the Old Partnership.
 
     A Remaining Unitholder will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Unitholders in the Old Partnership will carry over
intact into the New Partnership. Any Termination may change (and possibly
shorten) a Remaining Unitholder's holding period with respect to its units in
your partnership for Federal income tax purposes.
 
     The New Partnership's adjusted tax basis in its assets will carry over from
the Old Partnership's basis in such assets immediately before the Termination.
Any Termination may also subject the assets of the New Partnership to
depreciable lives in excess of those currently applicable to the Old
Partnership. This would generally decrease the annual average depreciation
deductions allocable to the Remaining Unitholders following consummation of the
offer (thereby increasing the taxable income allocable to their retained units
each year), but would have no effect on the total depreciation deductions
available over the useful lives of the assets of your partnership.
 
     Section 704(c) of the Code will apply to future allocation of income, gain,
loss and deductions with respect to any New Partnership assets among the AIMCO
Operating Partnership and the Remaining Unitholders following the consummation
of the offer only to the extent that such assets were Section 704(c) property in
the hands of the Old Partnership immediately prior to the Hypothetical
Contribution. Moreover, subject to the Code's anti-abuse regulations, the New
Partnership will not be required to apply the same Section 704(c) allocation
method applied by the Old Partnership. The Hypothetical Contribution will not
trigger a new five-year holding period for purposes of measuring
post-contribution appreciation of assets for the unitholder who contributed such
assets.
 
     Elections as to certain tax matters previously made by the Old Partnership
prior to Termination will not be applicable to the New Partnership unless the
New Partnership chooses to make the same elections.
 
     Additionally, upon a Termination, the Old Partnership's taxable year will
close for all unitholders. In the case of a Remaining Unitholder reporting on a
tax year other than a calendar year, the closing of your partnership's taxable
year may result in more than 12 months' taxable income or loss of the Old
Partnership being includible in such unitholder's taxable income for the year of
Termination.

OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-55
<PAGE>   3862
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-56
<PAGE>   3863
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $     (equivalent to $     on an
     annualized basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units, that you would receive in exchange for each of your partnership's
     units. Therefore, distributions with respect to the Preferred OP Units and
     Common OP Units that we are offering are expected to be        ,
     immediately following our offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-57
<PAGE>   3864
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-58

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."

                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF MATERIALS CONSIDERED
 
     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and
through June 30, 1998; (v) reviewed operating budgets for your partnership's
property for 1998, as prepared by your partnership; (vi) reviewed information
prepared by management relating to any debt encumbering your partnership's
property; (vii) reviewed information regarding market rental rates and

     your partnership; (ix) reviewed information provided by AIMCO concerning
the AIMCO Operating Partnership, the Common OP Units and the Preferred OP Units;
and (x) conducted other studies, analysis and inquiries as Stanger deemed
appropriate.
 
     In addition, Stanger discussed with management of your partnership and
AIMCO the market conditions for apartment properties, conditions in the market

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.

CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.

analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner from your partnership but may receive
reimbursement for expenses generated in that capacity and fees for additional
services. The property manager received management fees of $68,988 in 1996,
$73,266 in 1997 and $39,322 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Sturbrook Investors, Ltd. is a California limited partnership which raised
net proceeds of approximately $2,624,800 in 1982 through a private offering. The
promoter for the private offering of your partnership was Calmark Properties,
Inc. & Subs. Insignia acquired your partnership in 1992. AIMCO acquired Insignia
in October, 1998. There are currently a total of 36 limited partners of your
partnership and a total of 37 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on October 15, 1981 for the purpose of owning
and operating a single apartment property located in Richmond, Virginia, known
as "Sunrise V." Your partnership's property consists of 229 apartment units. The
total rentable square footage of your partnership's property is 212,425 square
feet. Your partnership's property had an average occupancy rate of approximately
95.63% in 1996 and 95.63% in 1997. The average annual rent per apartment unit is
approximately $6,142.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since 1992, your partnership's property has been managed by an entity which
is now an affiliate of AIMCO. Pursuant to the management agreement between the
property manager and your partnership, the property manager operates your
partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $68,988, $73,266 and $39,322, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is not limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2031
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is not limited
to the assets acquired with the initial equity raised through the sale of units
to the limited partners of your partnership or the assets initially contributed
to your partnership by the limited partners, as well as the debt financing
obtained by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $3,912,829, payable to Marine Midland and Bank of America, which
bears interest at a rate of 7.60%. The mortgage debt is due in November 2002.
Your partnership also has a second mortgage note outstanding of $139,037, which
bears interest at 7.60% and is due November 1998. Your partnership's agreement
of limited partnership also allows the general partner of your partnership to
lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Income
 
     Your partnership recognized net income of $246,607 for the six months ended
June 30, 1998, compared to $55,496 for the six months ended June 30, 1997. The
increase in net income of $191,111, or 344.37% was primarily the result of
increased rental revenue and decreased operating expenses. These factors are
discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$771,826 for the six months ended June 30, 1998, compared to $696,904 for the
six months ended June 30, 1997. The increase of $74,922, or 10.75% was primarily
the result of increased occupancy and a $5 per unit rate increase on select two
and three bedroom units.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $267,376 for the
six months ended June 30, 1998, compared to $377,888 for the six months ended
June 30, 1997, a decrease of $110,512 or 29.24%. The decrease was primarily the
result of advertising, resident relations, and non-capitalized exterior repairs
and maintenance. Management expenses totaled $39,322 for the six months ended
June 30, 1998, compared to $34,496 for the six months ended June 30, 1997, an
increase of $4,826, or 13.99%. The increase resulted from an increase in rental
revenue, as the management fees are a percentage of total revenue.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $13,663 for the six months
ended June 30, 1998 compared to $12,320 for the six months ended June 30, 1997,
a decrease of $1,343 or 10.90%. The decrease is due to a general decrease in
various administrative expenses.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $153,271 for the six months ended June 30, 1998, compared to
$159,951 for the six months ended June 30, 1997, a decrease of $6680, or 4.18%.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized net income of $194,729 for the year ended
December 31, 1997, compared to a net loss of $64,258 for the year ended December
31, 1996. The increase in net income of $258,987 was primarily the result of
increased rental revenue, decreased operating expenses and a $140,000 decrease
in depreciation expense due to 15 year property becoming fully depreciated after
1996.

     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,479,648 for the year ended December 31, 1997, compared to $1,381,966 for the
year ended December 31, 1996. The increase of $97,682, or 7.07%. Was primarily
due to increased rental rates and a slight increase in occupancy. There was also
an increase in other revenue because of increases in lease cancellation fees.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $720,923 for the
year ended December 31, 1997, compared to $740,554 for the year ended December
31, 1996, a decrease of $19,631 or 2.65%. Management expenses totaled $73,266
for the year ended December 31, 1997, compared to $68,988 for the year ended
December 31, 1996, an increase of $4,278, or 6.20%. This increase is due to

increase of $2,676 or 19.42%. The increase is primarily due to an increase in
general partner reimbursements and timing of audit expenditure.

costs, totaled $364,392 for the year ended December 31, 1997, compared to

related to non-capitalizable property improvements. Management Expenses totaled
$68,988 for the year ended December 31, 1996, compared to $67,600 for the year
ended December 31, 1995, an increase of $1,388 or 2.05%.

December 31, 1996 compared to $89,317 for the year ended December 31, 1995, a

expenditures and reclassification of certain general and administrative expenses
to operating expenses.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $169,403 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, your partnership, to the extent of its assets,
will indemnify and hold harmless the general partner of your partnership and its
affiliates from any expense, liability or loss resulting from any act or
omission by the general partner within the scope of the authority conferred by
your partnership's agreement of limited partnership, except for acts or
omissions constituting fraud, bad faith, willful misconduct or gross negligence,
including all such liabilities under Federal and state securities laws as
permitted by law. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     If such a claim for indemnification (other than for expenses incurred in a
successful defense) is asserted against your partnership, your partnership will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy and will be governed by the
final adjudication of such issue. As part of its assumption of liabilities in
the consolidation, AIMCO will indemnify the general partner of your partnership
and their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated year were determined
based upon operations of your partnership during the preceding year.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the
 
                                      S-79
<PAGE>   3886
 
general partner of your partnership under your partnership's agreement of
limited partnership, and (b) in order to track compliance with safe harbor
provisions to avoid treatment as a "publicly traded partnership" for tax
purposes. However, the general partner of your partnership does not monitor or
regularly receive or maintain information regarding the prices at which
secondary sale transactions in the units have been effectuated. The general
partner of your partnership estimates, based solely on the transfer records of
your partnership (or your partnership's transfer agent), that there have been no
units transferred in sale transactions (excluding transactions believed to be
between related parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation and distributions that would have
been paid to the general partner of your partnership, or the company paid to the
property manager or AIMCO and its affiliates.

     The accompanying unaudited financial statements of Sturbrook Investors,
LTD. as of June 30, 1998 and for the six months ended June 30, 1998 and 1997
have been prepared in accordance with generally accepted accounting principles
for interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It

NOTE A -- ORGANIZATION
 
  Description of Partnership
 
     Sturbrook Investors, Ltd., a California limited partnership (the
"Partnership"), was formed in October 1981 to acquire and operate a 229-unit
apartment complex in Richmond, Virginia. This property was acquired from Calmark
Asset Management, Inc. (CAMI), an affiliate of the General Partner, Sturbrook
Investors, Inc., a California corporation. In January 1993, MAE California,
Inc., an affiliate of Insignia Financial Group, Inc., purchased all of the
outstanding stock of the Corporate General Partner and assumed the role and
obligations of the Managing General Partner of the Partnership.
 
     The Partnership will terminate on December 31, 2031 unless terminated
sooner by the retirement or dissolution of the General Partner or unless the
Partners elect to continue the Partnership.
 
  Allocations to Partners
 
     In general, income and losses from operations and losses upon sale of the
property and/or dissolution of the Partnership are allocated 1% to the General
Partner and 99% to the Limited Partners.
 
     Income from disposition or partial disposition of the Partnership's
property and income upon termination and liquidation of the Partnership will be
allocated as follows:
 
          a. To all partners until they have been allocated an amount
             attributable to the recapture of deductions taken that have been
             previously allocated to them with respect to assets sold.
 
          b. To all partners until they have been allocated sufficient income to
             recover any losses previously allocated to them.
 
          c. Any remaining income will be allocated so as to produce a 5:14
             ratio between the aggregate positive adjusted capital account
             balances of the General Partner and the aggregate positive adjusted
             capital account balances of the Limited Partners after accounting
             for the distributions described below.
 
  Cash Distributions
 
     Net cash from operations is to be distributed not less than quarterly and
not later than ninety days after the end of each fiscal quarter of the
Partnership in the following order of priority:
 
          a. 1% to the General Partner and 99% to the Limited Partners as a
             class until such time as the Limited Partners have received in the
             aggregate an amount equal to an 8% per annum cumulative (but not
             compounded) return on their adjusted investment interest (as
             defined).
 
          b. The remainder is allocated 25% to the General Partner and 75% to
             the Limited Partners as a class. In general, any proceeds remaining
             after the sale of the properties and dissolution of the Partnership
             shall be distributed to the Partners in accordance with their
             capital accounts after payment of certain items specified in the
             Partnership Agreement.
 
NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Method of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally
 
                                       F-9
<PAGE>   3897
                           STURBROOK INVESTORS, LTD.
                       (A CALIFORNIA LIMITED PARTNERSHIP)
 
                        NOTES TO FINANCIAL STATEMENTS --
              FEDERAL INCOME TAX BASIS (UNAUDITED) -- (CONTINUED)
 
accepted accounting principles primarily in the timing of recognition of revenue
and certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determinations by taxing authorities.
 
  Apartment Property
 
     The apartment property is stated at cost. Depreciation of the apartment
property has been provided using the accelerated cost recovery method (1) for
real property over 15 years for additions prior to March 16, 1984 and (2) for
personal property over 5 years for additions prior to January 1, 1987. As a
result of the Tax Reform Act of 1986, for additions after December 31, 1986, the
modified accelerated cost recovery method is used for depreciation of (1) real
property additions over 27 1/2 years and (2) personal property additions over 7
years.
 
  Restricted Escrows
 
     Reserve Account
 
     A general Reserve Account was established to cover necessary repairs and
replacements of existing improvements, debt service, out-of-pocket expenses
incurred for ordinary and necessary administrative tasks, and payment of real
property taxes and insurance premiums. The Partnership is required to deposit
net operating income (as defined in the mortgage note) to the reserve account
until it equals $1,000 per apartment unit or $229,000 in total. The balance at
December 31, 1997 is $191,492, which includes interest.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash and cash equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits." Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit.
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the respective loans.

              FEDERAL INCOME TAX BASIS (UNAUDITED) -- (CONTINUED)
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state and
taxation codes, partnerships are generally not subject to income taxes. For tax
purposes, any income or loss realized is that of the individual partners, not
the Partnership.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.

     The discount is reflected as a reduction of the mortgage notes payable and
increases the effective rate of the debt to 8.76%.
 
     The mortgage notes payable are non-recourse and require prepayment
penalties if repaid prior to maturity and prohibit resale of the property
subject to the existing indebtedness. The mortgage notes payable are secured by
pledge of the apartment property and by pledge of revenues from the apartment
property.
 
     Scheduled principal payments of mortgage notes payable subsequent to
December 31, are as follows:

NOTE A -- ORGANIZATION
 
  Description of Partnership
 
     Sturbrook Investors, Ltd., a California limited partnership (the
"Partnership"), was formed in October 1981 to acquire and operate a 229-unit
apartment complex in Richmond, Virginia. This property was acquired from Calmark
Asset Management, Inc. (CAMI), an affiliate of the General Partner, Sturbrook,
Investors, Inc., a California corporation. In January 1993, MAE California,
Inc., an affiliate of Insignia Financial Group, Inc., purchased all of the
outstanding stock of the Corporate General Partner and assumed the role and
obligations of Managing General Partner of the Partnership.
 
     The Partnership will terminate on December 31, 2031 unless terminated
sooner by the retirement or dissolution of the General Partner or unless the
Partners elect to continue the Partnership.
 
  Allocations to Partners
 
     In general, income and losses from operations and losses upon sale of the
property and/or dissolution of the Partnership are allocated 1% to the General
Partner and 99% to the Limited Partners.
 
     Income from disposition or partial disposition of the Partnership's
property and income upon termination and liquidation of the Partnership will be
allocated as follows:
 
          a. To all partners until they have been allocated an amount
             attributable to the recapture of deductions taken that have been
             previously allocated to them with respect to assets sold.
 
          b. To all partners until they have been allocated sufficient income to
             recover any losses previously allocated to them.
 
          c. Any remaining income will be allocated so as to produce a 5:14
             ratio between the aggregate positive adjusted capital account
             balances of the General Partner and the aggregate positive adjusted
             capital account balances of the Limited Partners after accounting
             for the distributions described below.
 
  Cash Distributions
 
     Net cash from operations is to be distributed not less than quarterly and
not later than ninety days after the end of each fiscal quarter of the
Partnership in the following order of priority:
 
          a. 1% to the General Partner and 99% to the Limited Partners as a
             class until such time as the Limited Partners have received in the
             aggregate an amount equal to an 8% per annum cumulative (but not
             compounded) return on their adjusted investment interest (as
             defined).
 
          b. The remainder is allocated 25% to the General Partner and 75% to
             the Limited Partners as a class. In general, any proceeds remaining
             after the sale of the properties and dissolution of the Partnership
             shall be distributed to the Partners in accordance with their
             capital accounts after payment of certain items specified in the
             Partnership Agreement.
 
NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Method of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally
 
                                      F-17
<PAGE>   3905
                           STURBROOK INVESTORS, LTD.
                       (A CALIFORNIA LIMITED PARTNERSHIP)
 
                        NOTES TO FINANCIAL STATEMENTS --
              FEDERAL INCOME TAX BASIS (UNAUDITED) -- (CONTINUED)
 
accepted accounting principles primarily in the timing of recognition of revenue
and certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determination by taxing authorities.
 
  Apartment Property
 
     The apartment property is stated at cost. Depreciation of the apartment
property has been provided using the accelerated cost recovery method (1) for
real property over 15 years for additions prior to March 16, 1984 and (2) for
personal property over 5 years for additions prior to January 1, 1987. As a
result of the Tax Reform Act of 1986, for additions after December 31, 1986, the
modified accelerated cost recovery method is used for depreciation of (1) real
property additions over 27 1/2 years and (2) personal property additions over 7
years.
 
  Restricted Escrows
 
     Capital Improvement Account
 
     At December 31, 1996, the balance remaining in the "capital improvement
escrow" was $8,263. Upon completion of the scheduled property improvements, any
excess funds will be returned for property operations.
 
     Reserve Account
 
     In addition to the Capital Improvement Account, a general Reserve Account
was established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. The Partnership is required to deposit net operating income (as
defined in the mortgage note) to the reserve account until it equals $1,000 per
apartment unit or $229,000 in total. The balance at December 31, 1996 is
$233,106, which includes interest.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage to the unit.

  Present Value Discounts
 
     Periodically, the Partnership incurs debt at below market rates for similar
debt. Present value discounts are recorded on the basis of prevailing market
rates and are amortized on a straight-line method over the life of the related
debt.
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the respective loans.
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.

     The discount is reflected as a reduction of the mortgage notes payable and
increases the effective rate of the debt to 8.76%.
 
     The mortgage notes payable are non-recourse and require prepayment
penalties if repaid prior to maturity and prohibit resale of the property
subject to the existing indebtedness. The mortgage notes payable are secured by
pledge of the apartment property.

1. ORGANIZATION
 
  Description of Partnership
 
     Sturbrook Investors, Ltd., a California limited partnership (the
"Partnership"), was formed in October 1981 to acquire and operate a 229-unit
apartment complex in Richmond, Virginia. This property was acquired from Calmark
Asset Management, Inc. (CAMI), an affiliate of the General Partner, Sturbrook
Investors, Inc., a California corporation. In January 1993, MAE California,
Inc., an affiliate of Insignia Financial Group, Inc., purchased all of the
outstanding stock of the Corporate General Partner and assumed the role and
obligations of the Managing General Partner of the Partnership.
 
     The Partnership will terminate on December 31, 2031 unless terminated
sooner by the retirement or dissolution of the General Partner or unless the
Partners elect to continue the Partnership.
 
  Allocations to Partners
 
     In general, income and losses from operations and losses upon sale of the
property and/or dissolution of the Partnership are allocated 1% to the General
Partner and 99% to the Limited Partners.
 
     Income from disposition or partial disposition of the Partnership's
property and income upon termination and liquidation of the Partnership will be
allocated as follows:
 
          a. To all partners until they have been allocated an amount
             attributable to the recapture of deductions taken that have been
             previously allocated to them with respect to assets sold.
 
          b. To all partners until they have been allocated sufficient income to
             recover any losses previously allocated to them.
 
          c. Any remaining income will be allocated so as to produce a 5:14
             ratio between the aggregate positive adjusted capital account
             balances of the General Partner and the aggregate positive adjusted
             capital account balances of the Limited Partners after accounting
             for the distributions described below.
 
  Cash Distributions
 
     Net cash from operations is to be distributed not less than quarterly and
not later than ninety days after the end of each fiscal quarter of the
Partnership in the following order of priority:
 
          a. 1% to the General Partner and 99% to the Limited Partners as a
             class until such time as the Limited Partners have received in the
             aggregate an amount equal to an 8% per annum cumulative (but not
             compounded) return on their adjusted investment interest (as
             defined).
 
          b. The remainder is allocated 25% to the General Partner and 75% to
             the Limited Partners as a class. In general, any proceeds remaining
             after the date of the properties and dissolution of the Partnership
             shall be distributed to the Partners in accordance with their
             capital accounts after payment of certain items specified in the
             Partnership Agreement.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Method of Accounting
 
     The Partnership's financial statements are prepared using the tax accrual
method of accounting as set forth in the Federal income tax code and
regulations. This method of accounting differs from generally
 
                                      F-25
<PAGE>   3913
                           STURBROOK INVESTORS, LTD.

                        NOTES TO FINANCIAL STATEMENTS --
              FEDERAL INCOME TAX BASIS (UNAUDITED) -- (CONTINUED)
 
accepted accounting principles primarily in the timing of recognition of revenue
and certain expenses, recognition of certain costs of the Project, methods of
depreciation and useful lives of assets, and recognition and amortization of
deferred fees.
 
     The Partnership's Federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations to many
types of transactions is susceptible to varying interpretations, amounts
reported in the financial statements could be changed at a later date upon final
determination by taxing authorities.
 
  Apartment Property
 
     The apartment property is stated at cost. Depreciation of the apartment
property has been provided using the accelerated cost recovery method (1) for
real property over 15 years for additions prior to March 15, 1984 and (2) for
personal property over 5 years for additions prior to January 1, 1987. As a
result of the Tax Reform Act of 1986, for additions after December 31, 1986, the
modified accelerated cost recovery method is used for depreciation of (1) real
property additions over 27 1/2 years and (2) personal property additions over 7
years.
 
  Restricted Escrows
 
     Capital Improvement Account
 
     At December 31, 1995, the balance remaining in the "capital improvement
escrow" was $10,253. Upon completion of the scheduled property improvements, any
excess funds will be returned for property operations.
 
     Reserve Account
 
     In addition to the Capital Improvement Account, a general Reserve Account
was established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. The Partnership is required to deposit net operating income (as
defined in the mortgage note) to the reserve account until it equals $1,000 per
apartment unit or $229,000 in total. The balance at December 31, 1995 is
$234,529, which includes interest.
 
  Syndication Costs
 
     Syndication costs are stated at cost to the Partnership and are not
amortizable for Federal income tax purposes, but result in a capital loss upon
the dissolution of the Partnership.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Cash
 
     The Partnership considers only unrestricted cash to be cash. At certain
times, the amount of cash deposited at a bank may exceed the limit on insured
deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage to the unit.

  Present Value Discounts
 
     Periodically, the Partnership incurs debt at below market rates for similar
debt. Present value discounts are recorded on the basis of prevailing market
rates and are amortized on a straight-line method over the life of the related
debt.
 
  Loan Costs
 
     Loan costs are being amortized on a straight-line basis over the life of
the respective loans.
 
  Income Taxes
 
     Under provisions of the Internal Revenue Code and applicable state revenue
and taxation codes, partnerships are generally not subject to income taxes. For
tax purposes, any income or loss realized is that of the individual partners,
not the Partnership.
 
  Use of Estimates
 
     The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred.
 
3. MORTGAGE NOTES PAYABLE
 
     Mortgage notes payable at December 31, 1995 consist of the following:

Mortgage payable to Bank of America, secured by a first deed
  of trust on the property. This note bears interest at 7.6%
  per annum. Principal and interest payments of $35,481 are
  payable monthly, with a balloon payment of $3,276,927 due
  on November 15, 2002......................................    $4,204,324
Mortgage payable to Bank of America, secured by a second
  deed of trust on the property. This note bears interest at
  7.6% per annum. Interest only payments of $881 are payable
  monthly, with the principal and unpaid interest due on
  November 15, 2002.........................................       139,037

Less unamortized loan discounts.............................      (220,426)
                                                                ----------
                                                                $4,122,935
                                                                ==========
</TABLE>
 
     The discount is reflected as a reduction of the mortgage notes payable and
increases the effective rate of the debt to 8.76%.
 
     The mortgage notes payable are non-recourse and require prepayment
penalties if repaid prior to maturity and prohibit resale of the property
subject to the existing indebtedness. The mortgage notes payable are secured by
pledge of the apartment property and by pledge of revenues from the apartment
property.

4. TRANSACTIONS WITH AFFILIATED PARTIES
 
     Property management fees of $67,600 and reimbursements for general partner
expenses of $8,613 (included in other expenses) are included in the statement of
revenues and expenses -- Federal income tax basis and relate to services
provided by affiliates of the Partnership's Managing General Partner.
 
5. CONTINGENCY
 
     The Partnership's apartment property is being adversely affected by soil
erosion from an adjacent creek. Cost estimates to repair the damage and to
prevent further erosion have not been determined. Expenditures for repairs and
related preventive maintenance will be incurred by the Partnership and are not
reimbursable by insurance. Although a liability has not been recorded for these
expenditures, management does not believe that the amounts will have a material
impact on the Partnership.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   3917
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   3918
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Sycamore Creek Associates, L.P. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   3923
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   3924
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0 per unit for the six months ended
     June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   3925
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   3926
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   3929
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   3930
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   3931
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   3932
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   3933
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units in your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   3934
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the six months ended June 30, 1998, we
       paid distributions of $1.125 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

TERMS OF THE OFFER
 
     General. We are offering to acquire up to        % of the outstanding units

     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other

contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a
broker, dealer, commercial bank, trust company, custodian or nominee and you
wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an

                                      S-14
<PAGE>   3936
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers) including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY

     BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR
TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN
THIS PROSPECTUS SUPPLEMENT AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO
STOCKHOLDERS," "FEDERAL INCOME TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND
OP UNITHOLDERS" AND "OTHER TAX CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND
CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO
YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   3939
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership, but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $99,666 in 1996, $101,578 in 1997 and $51,911 for
the first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Sycamore Creek Associates, L.P. is a
Delaware limited partnership which was formed on July 13, 1984 for the purpose
of owning and operating a single apartment
property located in Cincinnati, Ohio, known as "Sycamore Creek Apartments." In
1984, it completed a private placement of units. Your partnership has no
employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and
                                      S-18
<PAGE>   3940
 
your partnership, the property manager operates your partnership's property,
establishes rental policies and rates and directs marketing activities. The
property manager also is responsible for maintenance, the purchase of equipment
and supplies, and the selection and engagement of all vendors, suppliers and
independent contractors. The property manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2008, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $7,213,952, payable to Marine Midland and
Bank of America, which bears interest at a rate of 7.60%. The mortgage debt is
due in November 2002. Your partnership also has a second mortgage note
outstanding of $256,342, on the same terms as the first mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   3948
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   3949
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of $0
with respect to your units, distributions with respect to the Preferred OP Units
and Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   3950
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   3951
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership.
 
                                      S-30
<PAGE>   3952
 
However, one class of outstanding Partnership Preferred Units has prior
distribution rights and the Tax-Deferral   % Preferred OP Units rank equal to
five other outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the six months ended June 30, 1998, we paid distributions of
       $1.125 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your units
       since the inception of your partnership. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   3954
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   3955
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole
 
                                      S-34
<PAGE>   3956
 
discretion, which determination shall be final and binding on all parties. The
AIMCO Operating Partnership reserves the absolute right to reject any or all
tenders of any particular unit determined by it not to be in proper form or if
the acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   3957
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   3958
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     existing at the time of the commencement of the offer, in the sole judgment
     of the AIMCO Operating Partnership, a material acceleration or worsening

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   3962
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   3963
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
                                      S-42
<PAGE>   3964
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
                                      S-43
<PAGE>   3965
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   3972
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   3973
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   3975
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.

     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $0.00 with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1998 distributions of $     with
     respect to your units, distributions with respect to the Preferred OP Units
     and Common OP Units being offered are expected to be      , immediately
     following the offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   3977
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.

independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,

AIMCO concerning,
 
                                      S-59

     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity. The property manager received management fees of
$99,666 in 1996, $101,578 in 1997 and $51,911 for the first six months of 1998.
The AIMCO Operating Partnership has no current intention of changing the fee
structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Sycamore Creek Associates, L.P. is a Delaware limited partnership. Insignia
acquired your partnership in December 1991. AIMCO acquired Insignia in October,
1998. There are currently a total of 72 limited partners of your partnership and
a total of 45.99 units of your partnership outstanding. Your partnership is in
the business of owning and managing residential housing. Currently, your
partnership owns and manages the single apartment property described below. Your
partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on July 13, 1984 for the purpose of owning and
operating a single apartment property located in Cincinnati, Ohio, known as
"Sycamore Creek Apartments". Your partnership's property consists of 295
apartment units. The total rentable square footage of your partnership's
property is 266,350 square feet. Your partnership's property had an average
occupancy rate of approximately 89.15% in 1996 and 89.15% in 1997. The average
annual rent per apartment unit is approximately $6,311.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $99,666, $101,578 and $51,911, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2008
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $7,213,952, payable to Marine Midland and Bank of America, which
bears interest at a rate of 7.60%. The mortgage debt is due in November 2002.
Your partnership also has a second mortgage note outstanding of $256,342, on the
same terms as the first mortgage note. Your partnership's agreement of limited
partnership also allows the general partner of your partnership to lend funds to
your partnership. Currently, the general partner of your partnership has no loan
outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein.
 
  Results of Operations
 
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
 
     Net Income
 
     Your partnership recognized net income of $67,732 for the six months ended
June 30, 1998, compared to $80,400 for the six months ended June 30, 1997. A
decrease of $12,668, or 15.76%. The decrease is primarily the result of an
increase in accrued expenses during the interim period, offset by an increase in
rental revenue and a decrease in operating expenses.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$991,909 for the six months ended June 30, 1998, compared to $942,631 for the
six months ended June 30, 1997. The increase of $49,278, or 5.23% is primarily
the result of increased occupancy due to the reopening of several of the
flood-damaged units coupled with increased rental rates.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $375,998 for the
six months ended June 30, 1998, compared to $390,688 for the six months ended
June 30, 1997, a decrease of $14,690 or 3.76%. Management expenses totaled
$51,911 for the six months ended June 30, 1998, compared to $48,206 for the six
months ended June 30, 1997, an increase of $3,705, or 7.69%. The increase
resulted from increased rental revenue as management fees are calculated as a
percentage of revenue.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $32,167 for the six months
ended June 30, 1998 compared to $25,174 for the six months ended June 30, 1997,
an increase of $6,993 or 27.78%. The increase is primarily due to an increase in
training and travel expenses.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $327,825 for the six months ended June 30, 1998, compared to
$336,221 for the six months ended June 30, 1997, a decrease of $8,396, or 2.50%.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized net income of $163,481 for the year ended
December 31, 1997, compared to a net loss of $46,944 for the year ended December
31, 1996. The increase in net income of $210,425 was primarily the result of a
casualty gain of $147,000 incurred due to two fires in the clubhouse and a
flood. There was also an increase in total revenue and a decrease in operating
expenses. These factors are discussed in more detail in the following
paragraphs.

<PAGE>   3996
 
          Revenues
 
     Rental and other property revenues from the partnership's property totaled
$2,041,188 for the year ended December 31, 1997, compared to $2,004,396 for the
year ended December 31, 1996, an increase of $36,792, or 1.84%.
 
     Expenses
 
     Operating expenses consisting of utilities (net of reimbursements received
from tenants), contract services, turnover costs, repairs and maintenance,
advertising and marketing, and insurance, totaled $902,610 for the year ended
December 31, 1997, compared to $923,126 for the year ended December 31, 1996, a
decrease of $20,516 or 2.22%. Management expenses totaled $101,578 for the year
ended December 31, 1997, compared to $99,666 for the year ended December 31,
1996, an increase of $1,912, or 1.92%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $57,254 for the year ended
December 31, 1997 compared to $60,560 for the year ended December 31, 1996, a
decrease of $3,306 or 5.46%. The decrease is primarily due to a decrease in
contracted service fees.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $666,616 for the year ended December 31, 1997, compared to
$679,466 for the year ended December 31, 1996, a decrease of $12,850, or 1.89%.
 
     Comparison of the Year Ended December 31, 1996 to the Year Ended December
31, 1995
 
     Net Income
 
     Your partnership recognized a net loss of $46,944 for the year ended
December 31, 1996, compared to a net loss of $130,568 for the year ended
December 31, 1995. The decrease in net loss of $83,624, or 64.05% was primarily
the result of a decrease in depreciation expense due to 10 yr property becoming
fully depreciated in 1995, coupled with an increase in total revenue, offset by
an increase in operating expenses. These factors will be discussed further in
the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$2,004,396 for the year ended December 31, 1996, compared to $1,945,886 for the
year ended December 31, 1995, an increase of $58,510, or 3.01%.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $923,126 for the
year ended December 31, 1996, compared to $882,490 for the year ended December
31, 1995, an increase of $40,636 or 4.60%. Management expenses totaled $99,666
for the year ended December 31, 1996, compared to $97,108 for the year ended
December 31, 1995, an increase of $2,558, or 2.63%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $60,560 for the year ended
December 31, 1996 compared to $55,031 for the year ended December 31, 1995, an
increase of $5,529 or 10.05%. The increase is primarily due to a general
increase in various administrative expenses.

<PAGE>   3997
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $679,466 for the year ended December 31, 1996, compared to
$691,871 for the year ended December 31, 1995, a decrease of $12,405, or 1.79%.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $108,254 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner will not incur any
liability to your partnership or any other partner for any mistakes or errors in
judgment or for any act or omission believed by it in good faith to be within
the scope of authority conferred upon it by your partnership's agreement of
limited partnership. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will, to the extent permitted by law, indemnify and save
harmless the general partner against and from any personal loss, liability
(including attorneys' fees) or damage incurred by it as the result of any act or
omission in its capacity as general partner unless such loss, liability or
damage results from gross negligence or willful misconduct of the general
partner. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not paid distributions during the past five years.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
                                      S-76
<PAGE>   3998
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in respect of its capacity as general partner
interest from your partnership as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation and distributions that would have
been paid to the general partner of your partnership, or the compensation paid
to the property manager or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.
 
     Below is an itemized statement of the estimated expenses incurred and to be

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Sycamore Creek
Associates, Limited as of June 30, 1998 and for the six months ended June 30,
1998 and 1997 have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.
 
NOTE B -- EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT
 
     On March 17, 1998, Insignia Financial Group, Inc., an affiliate of the
corporate general partner of the Partnership, entered into an agreement to merge
its national residential property management operations and its controlling
interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO
acquired the corporate general partner and the company that manages the
Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Sycamore Creek Associates, Limited:
 
     We have audited the accompanying balance sheets of Sycamore Creek
Associates, Limited as of December 31, 1997 and 1996, and the related statements
of operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Sycamore Creek Associates,
Limited as of December 31, 1997 and 1996, and the results of its operations and
its cash flows for the years then ended, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Sycamore Creek Associates, Limited (the "Partnership") was organized as a
limited partnership under the laws of the State of Delaware pursuant to a
Limited Partnership Agreement and Certificate of Limited Partnership dated
September 28, 1984. The Partnership owns and operates a 295 unit apartment
complex, Sycamore Creek Apartments, in Cincinnati, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include unamortized deferred
loan costs of $113,787 and $136,934, respectively, which are amortized over the
term of the related borrowing. Deferred loan costs are shown net of accumulated
amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.

  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the
following:

                           DECEMBER 31, 1995 AND 1994
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Sycamore Creek Associates, Limited (the "Partnership") was organized as a
limited partnership under the laws of the State of Delaware pursuant to a
Limited Partnership Agreement and Certificate of Limited Partnership dated
September 28, 1984. The Partnership owns and operates a 295 unit apartment
complex, Sycamore Creek Apartments, in Cincinnati, Ohio.
 
     The Partnerships' Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1995 and 1994 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers cash and
all highly liquid investments, with an original maturity of three months or less
when purchased, to be cash and cash equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Reclassifications
 
     Certain 1994 amounts have been reclassified to conform to the 1995
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4022
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4023
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   4028
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4029
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $100 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   4030
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   4031
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multi family apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4034
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4035
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4036
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4037
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4038
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   4039
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the

<PAGE>   4041
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant

property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.

CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT

YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD
REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND

CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   4044
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Unlike the general partner of the AIMCO Operating Partnership, the
general partner of your partnership is entitled to compensation for its services
as general partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Unit, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $22,500
(which may be increased pro rata to up to $36,000 if, in the discretion of the
general partner, the offering of units is increased to $16,180,000) beginning in
1991, increasing annually at a rate of 6% beginning in 1992 and may receive
reimbursement for expenses generated in that capacity from your partnership. The
property manager received management fees of $137,205 in 1996, $152,785 in 1997
and $80,776 for the first six months of 1998. We have no current intention of
changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Texas Residential Investors Limited
Partnership is a Delaware limited partnership which was formed on May 21, 1991
for the purpose of owning and operating a small number of apartment properties
located in Dallas, Texas and Houston, Texas, known as "Crossbridge Apartments,"
"Park at Deerbrook Apartments" and "Ryan's Pointe Apartments," respectively. In
1991, it completed a private placement of units that raised net proceeds of
approximately $10,500,000. Crossbridge
 
                                      S-18
<PAGE>   4045
 
Apartments consists of 160 apartment units, Park at Deerbrook Apartments
consists of 280 apartment units and Ryan's Pointe Apartments consists of 100
apartment units. Your partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2040, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $4,444,391, payable to Metropolitan Life,
which bears interest at a rate of 7.61%. The mortgage debt is due in December
2002. Your partnership's agreement of limited partnership also allows your
general partner to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4053
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     In addition, if there is a sale or exchange of 50% or more of the total
interest in capital and profits of your partnership within any 12-month period,
including sales or exchanges resulting from the offer, your partnership will
terminate for Federal income tax purposes. Any such termination may, among other
things, subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
if you do not tender all of your units (thereby increasing the taxable income
allocable to your units each year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to your units that you choose to retain.
 
     The particular tax consequences for you of our offer will depend upon a
number of factors related to your tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership (and
therefore are no longer subject to the "passive" loss rules with respect to your
partnership). Because the income tax consequences of tendering units will not be
the same for everyone, you should consult your own tax advisor with specific
reference to your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the
 
                                      S-27
<PAGE>   4054
 
value of your units or your partnership. Proceeds of future asset sales or
refinancings by the AIMCO Operating Partnership generally will be reinvested
rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been declines in
the trading prices for many REIT securities. There may be subsequent changes in
public market valuations of real estate assets relative to private market
valuations of real estate assets. We cannot predict the price at which the Class
I Preferred Stock or the Class A Common Stock will trade following the time at
which Preferred OP Units or Common OP Units may be redeemed for shares of Class
I Preferred Stock or Class A Common Stock. Furthermore, the liquidity of the
Class I Preferred Stock and the Class A Common Stock at the time at which OP
Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of $0
with respect to your units, distributions with respect to the Preferred OP Units
and Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your
 
                                      S-28
<PAGE>   4055
 
partnership to be transferred within a 12-month period. If we acquire a
significant interest in your partnership, through this offer, you may not be
able to transfer your units for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
                                      S-29
<PAGE>   4056
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.

     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of our offer, see "Risk Factors."

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4059
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign your rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998 IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially, all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4060
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   4061
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   4062
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   4063
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   4064
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   4067
 
that would be material to the business of your partnership, taken as a whole,
and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   4069
 
distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   4070
 
Parity Units ratably in the same proportion as the respective amounts that would
be payable on such Preferred OP Units and any such Parity Units if all amounts
payable thereon were paid in full. A voluntary or involuntary liquidation,
dissolution or winding up of the AIMCO Operating Partnership will not include a
consolidation or merger of the AIMCO Operating Partnership with one or more
partnerships, corporations or other entities, or a sale or transfer of all or
substantially all of the AIMCO Operating Partnership's assets. Upon any
liquidation, dissolution or winding up of the AIMCO Operating Partnership, after
all allocations shall have been made in full to the holders of Preferred OP
Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   4071
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   4072
 
in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original

original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             its affiliates may purchase or acquire shares of Class

                                                             of Class I Preferred Stock. The redemption price for
                                                             the Class I Preferred Stock (other than any portion

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4077
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4078
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4080
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   4081
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1997 distributions of $1,000 with
     respect to your units, distributions with respect to the Preferred OP Units
     and Common OP Units being offered are expected to be      , immediately
     following the offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   4082
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were

your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not
 
                                      S-58
<PAGE>   4085
 
     limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the
 
                                      S-59
<PAGE>   4086
 
     value of the partnership's property or other balance sheet assets and
liabilities or other information reviewed between the date of such information
provided and the date of the Fairness Opinion; that your partnership, AIMCO, and
the management of the partnership's property are not aware of any information or
facts that would cause the information supplied to Stanger to be incomplete or
misleading; that the highest and best use of the partnership's property is as
improved; and that all calculations were made in accordance with the terms of
your partnership's agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $22,500
(which may be increased pro rata to up to $36,000 if, in the discretion of the
general partner, the offering of units is increased to $16,180,000) beginning in
1991, increasing annually at a rate of 6% beginning in 1992 from your
partnership but may receive reimbursement for expenses generated in that
capacity. The property manager received management fees of $137,205 in 1996,
$152,785 in 1997 and $80,776 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Texas Residential Investors Limited Partnership is a Delaware limited
partnership which raised net proceeds of approximately $10,500,000 in 1991
through a private offering. The promoter for the private offering of your
partnership was Winthrop Securities Co., Inc. Insignia acquired your partnership
in November 1997. AIMCO acquired Insignia in October, 1998. There are currently
a total of 163 limited partners of your partnership and a total of 168 units of
your partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages a
small number of apartment properties described below. Your partnership has no
employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 21, 1991 for the purpose of owning and
operating a small number of apartment properties located in Dallas, Texas and
Houston, Texas, known as "Crossbridge Apartments", "Park at Deerbrook
Apartments" and "Ryan's Pointe Apartments," respectively. There are 160
apartment units in Crossbridge Apartments. Park at Deerbrook Apartments has 280
apartment units. In Ryan's Pointe Apartments, there are 100 apartment units. The
average rent per apartment unit is $5,746.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $137,205, $152,785 and $80,776, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2040
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding on "Ryan's Pointe Apartments" of $4,444,391 payable to Metropolitan
Life which bears interest at a rate of 7.61% and is due December 2002. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

paragraphs.

outstanding debt, capital improvements, and distributions paid to limited
partners. Your partnership has adequate sources of cash to finance its
operations, both on a short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates who perform services on behalf of your partnership will not incur
any liability, responsibility or accountability for damages or otherwise to your
partnership or any limited partner arising out of any acts performed or any
omission by any of them if they believed in good faith that such act or omission
was in the best interests of your partnership and such course of conduct did not
constitute negligence or misconduct on the part of the such person. As a result,
unitholders might have a more limited right of action in certain circumstances
than they would have in the absence of such a provision in your partnership's
agreement of limited partnership. The general partner of your partnership is
owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will indemnify and save harmless the general partner and
its affiliates who perform services on behalf of your partnership, to the full
extent permitted by law, against any loss, damage, liability, cost or expenses
(including reasonable attorneys' fees) incurred by them in connection with your
partnership provided that such loss, damage, liability, cost or expense was not
the result of negligence or misconduct on the part of such persons. Such
indemnity will be paid from, and only to the extent of, partnership assets.
However, the general partner, its affiliates and any placing broker will be
liable and not be indemnified from any loss, damage or cost resulting form the
violation of any Federal or state securities law in connection with the sale of
units unless (i) there has been a successful adjudication on the merits of each
count involving such securities law violation, (ii) such claims have been
dismissed with prejudice on the merits by a court of competent jurisdiction or
(iii) a court of competent jurisdiction approves a settlement of such claim. In
such claim for indemnification for Federal or state securities law violation,
the party seeking indemnification must place before the court the position of
the SEC and any other applicable regulatory agency with respect of the issue of
indemnification for securities law violations. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     No partnership funds will be used to purchase any insurance that insures
any party against any liability that is prohibited by your partnership's
agreement of limited partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The
original cost per unit was $62,500.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the
 
                                      S-76
<PAGE>   4103
 
     general partner of your partnership under your partnership's agreement of
limited partnership, and (b) in order to track compliance with safe harbor
provisions to avoid treatment as a "publicly traded partnership" for tax
purposes. However, the general partner of your partnership does not monitor or
regularly receive or maintain information regarding the prices at which
secondary sale transactions in the units have been effectuated. The general
partner of your partnership estimates, based solely on the transfer records of
your partnership (or your partnership's transfer agent), that there have been no
units transferred in sale transactions (excluding transactions believed to be
between related parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation and distributions that would have
been paid to the general partner of your partnership, or the company paid to the
property manager or AIMCO and its affiliates.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Texas Residential
Investors Limited Partnership and Subsidiary as of June 30, 1998 and for the six
months ended June 30, 1998 have been prepared in accordance with generally
accepted accounting principles for interim financial information. Accordingly,
they do not include all the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
Texas Residential Investors Limited Partnership
 
     We have audited the accompanying consolidated balance sheets of Texas
Residential Investors Limited Partnership and Subsidiary as of December 31, 1997
and 1996, and the related consolidated statements of operations, changes in
partners' capital and cash flows for the years then ended. These consolidated
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Texas
Residential Investors Limited Partnership and Subsidiary as of December 31, 1997
and 1996, and the results of their operations, and their cash flows for the
years then ended, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Texas Residential Investors Limited Partnership (the "Partnership" or the
"Investor Partnership"), a limited partnership, was formed on March 21, 1991
under the laws of the State of Delaware for the purpose of holding a general
partnership interest in Texas Apartment Investors General Partnership (the
"Operating Partnership"). The Operating Partnership has acquired three
properties consisting of an aggregate of 540 market-rate rental apartment units,
located in the Houston area and in Dallas, Texas. The Investor Partnership will
terminate on December 31, 2040, or earlier upon the occurrence of certain events
specified in the Investor Partnership Agreement.
 
     The general partner of the Investor Partnership is Winthrop Properties
Limited Partnership ("WPLP"), which is a Delaware limited partnership. The
initial limited partner of the Investor Partnership was AC Realty Co., Inc.,
which withdrew from the Partnership upon the first admission of investors. The
Investor Partnership sold 168 limited partnership units at $100,000 per unit.
 
  Principles of Consolidation and Subsidiary
 
     The consolidated financial statements include all the accounts of Texas
Residential Investors Limited Partnership and its majority-owned subsidiary,
Texas Apartment Investors General Partnership. All intercompany balances have
been eliminated in consolidation. Pursuant to the Operating Partnership's
general partnership agreement, the Investor Partnership has significant control
over major decisions, such as the sale or refinancing of the Operating
Partnership. Accordingly, the accompanying consolidated financial statements
have been consolidated and have been prepared on the accrual basis of accounting
in accordance with generally accepted accounting principles.
 
  Use of Estimates
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Deferred Costs
 
     Deferred costs which consist of loan fees, are capitalized and amortized
using the straight-line method over the term of the related agreement.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. The Operating Partnership
provides for depreciation of buildings and improvements on the straight-line
method over their estimated useful life for financial and reporting purposes.
For income tax purposes, accelerated methods and lives are used.
 
  Rental Income
 
     Rental income is recognized as rents become due. Rental payments received
in advance are deferred until earned. All leases between the Operating
Partnership and tenants of the properties are operating leases.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Income Taxes
 
     No provision is made for federal, state or local income taxes in the
consolidated financial statements of the Partnership. Partners are required to
report on their tax returns their allocable shares of income, gains, losses,
deductions and credits of the Partnership.
 
  Cash Equivalents
 
     For purposes of the consolidated statements of cash flows, the Investor and
Operating Partnerships consider all highly liquid investments with maturities of
less than three months to be cash equivalents.
 
NOTE B -- MORTGAGES PAYABLE
 
     On December 28, 1995, the Operating Partnership obtained two mortgage loans
by the same lender in the aggregate amount of $6,235,909, which are
collateralized by deeds of trust on the rental properties. The notes bear
interest at a rate of 7.61%. Principal and interest are payable by the Operating
Partnership in monthly installments of $46,530. A balloon payment of
approximately $5,656,731 and the accrued interest is payable in full on December
1, 2002.
 
     Under agreements with the mortgage lender, the Operating Partnership is
required to make monthly escrow deposits for taxes and insurance. The Operating
Partnership was required to make an initial deposit into a repair escrow for
repairs to the project upon obtaining the two mortgages in 1995.
 
     The liability of the Operating Partnership under the mortgage notes is
limited to the underlying value of the real estate collateral plus other amounts
deposited with the lender.
 
     Aggregate annual maturities of the mortgages payable over each of the next
five years are as follows:

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
Texas Residential Investors Limited Partnership
 
     We have audited the accompanying consolidated balance sheets of Texas
Residential Investors Limited Partnership and Subsidiary as of December 31, 1996
and 1995, and the related consolidated statements of operations, partners'
capital and cash flows for the years then ended. These consolidated financial
statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Texas
Residential Investors Limited Partnership and Subsidiary as of December 31, 1996
and 1995, and the results of their operations, and their cash flows for the
years then ended, in conformity with generally accepted accounting principles.

         TEXAS RESIDENTIAL INVESTORS LIMITED PARTNERSHIP AND SUBSIDIARY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Texas Residential Investors Limited Partnership (the "Partnership" or the
"Investor Partnership"), a limited partnership, was formed on March 21, 1991
under the laws of the State of Delaware for the purpose of holding a general
partnership interest in Texas Apartment Investors General Partnership (the
"Operating Partnership"). The Operating Partnership has acquired three
properties consisting of an aggregate of 540 market-rate rental apartment units,
located in the Houston area and in Dallas, Texas. The Investor Partnership will
terminate on December 31, 2040, or earlier upon the occurrence of certain events
specified in the Investor Partnership Agreement.
 
     The general partner of the Investor Partnership is Winthrop Properties
Limited Partnership ("WPLP"), which is a Delaware limited partnership. The
initial limited partner of the Investor Partnership was AC Realty Co., Inc.,
which withdrew from the Partnership upon the first admission of investors. The
Investor Partnership sold 168 limited partnership units at $100,000 per unit.
 
  Principles of Consolidation and Subsidiary
 
     The consolidated financial statements include all the accounts of Texas
Residential Investors Limited Partnership and its majority-owned subsidiary,
Texas Apartment Investors General Partnership. All intercompany balances have
been eliminated in consolidation. Pursuant to the Operating Partnership's
General Partnership agreement, the Investor Partnership has significant control
over major decisions, such as the sale or refinancing of the Operating
Partnership. Accordingly, the accompanying consolidated financial statements
have been consolidated and have been prepared on the accrual basis of accounting
in accordance with generally accepted accounting principles.
 
  Use of Estimates
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Deferred Costs
 
     Deferred costs which consist of loan fees, are capitalized and amortized
using the straight-line method over the term of the related agreement.
 
  Investment in Real Estate
 
     Investment in real estate is carried at cost. The Operating Partnership
provides for depreciation of buildings and improvements on the straight-line
method over their estimated useful life for financial and reporting purposes.
For income tax purposes, accelerated methods and lives are used.
 
  Rental Income
 
     Rental income is recognized as rents become due. Rental payments received
in advance are deferred until earned. All leases between the Operating
Partnership and tenants of the properties are operating leases.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Income Taxes
 
     No provision is made for federal, state or local income taxes in the
consolidated financial statements of the Partnership. Partners are required to
report on their tax returns their allocable shares of income, gains, losses,
deductions and credits of the Partnership.
 
  Cash Equivalents
 
     For purposes of the consolidated statements of cash flows, the Investor and
Operating Partnerships consider all highly liquid investments with maturities of
less than three months to be cash equivalents. The carrying amount of $171,943
approximates fair value because of the short maturity of this instrument.
 
NOTE B -- MORTGAGES PAYABLE
 
     On December 28, 1995, the Operating Partnership obtained two mortgage loans
by the same lender in the aggregate amount of $6,235,909 and are collateralized
by deeds of trust on the rental properties. The notes bear interest at a rate of
7.62%. Principal and interest are payable by the Operating Partnership in
monthly installments of $45,921. A balloon payment of approximately [MISSING
COPY]
 
     Under agreements with the mortgage lender, the Operating Partnership is
required to make monthly escrow deposits for taxes and insurance. The Operating
Partnership was required to make an initial deposit into a repair escrow for
repairs to the project upon obtaining the two mortgages in 1995.
 
     The liability of the Operating Partnership under the mortgage notes is
limited to the underlying value of the real estate collateral plus other amounts
deposited with the lender.
 
     Aggregate annual maturities of the mortgages payable over each of the next
five years are as follows:

apartment complexes for an aggregate purchase price of $11,935,000 beginning on
May 1, 1990, with the purchase of Crossbridge Apartments for $2,660,000. On
October 16, 1990, the Park at Deerbrook and Ryan's Pointe Apartments were

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4129
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4130
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Thurber Manor Associates, L.P. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   4135
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4136
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0.00 per unit for the six months
     ended June 30, 1998 due to capital improvements to your partnership's
     property funded from cash flow. We will pay fixed quarterly distributions
     of $               per unit on the Tax-Deferral   % Preferred OP Units
     before any distributions are paid to holders of Tax-Deferral Common OP
     Units. We pay quarterly distributions on the Tax-Deferral Common OP Units
     based on our funds from operations for that quarter. For the six months
     ended June 30, 1998, we paid distributions of $1.125 on each of the
     Tax-Deferral Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL
 
                                       S-3
<PAGE>   4137
 
     TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX
     CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
     TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX
     MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS
     AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX
     CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.

<PAGE>   4138
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multihousing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4141
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4142
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4143
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4144
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4145
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least 51% of the units of your partnership. In
     the absence of such consent, your only option for liquidation of your
     investment would be to sell your units in a private transaction. Any such
     sale could be at a very substantial discount from your pro rata share of
     the fair market value of your partnership's property and might involve
     significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   4146
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore

                                      S-14
<PAGE>   4148
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   4151
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership, but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $37,726 in 1996, $39,386 in 1997 and $20,480 for the
first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Thurber Manor Associates, L.P. is a
Delaware limited partnership which was formed on July 31, 1984 for the purpose
of owning and operating a single apartment property located in Columbus, Ohio,
known as "Thurber Manor Apartments." In 1984, it completed a private placement
of units that raised net proceeds of approximately $1,875,000. Thurber Manor
Apartments consists of 115 apartment units. Your partnership has no employees.

     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2008, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,341,104, payable to Marine Midland,
Bank of America and FNMA, which bears interest at a rate of 7.60%. The mortgage
debt is due in November 2002. Your partnership also has a second mortgage note
outstanding of $83,190, on the same terms as the first mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4160
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4161
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of
$0.00 with respect to your units for the six months ended June 30, 1998 were
$0.00. Therefore, due to capital improvement to your partnership's property
funded from cash flow, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
 
                                      S-28
<PAGE>   4162
 
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation
 
                                      S-29
<PAGE>   4163
 
methods to estimate the fair market value of your partnership's assets. Instead,
such assets would be valued through negotiations with prospective purchasers (in
many cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 51% of the units of your partnership. In the absence
of such consent, your only option for liquidation would be to sell your units in
a private transaction. Any such sale likely would be at a very substantial
discount from your pro rata share of the fair market value of your partnership's
property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   4164
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4166
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4167
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   4169
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   4171
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

     become aware of any facts relating to your partnership, its indebtedness or

     or other lending institutions, or (viii) in the case of any of the
     foregoing existing at the time of the commencement of the offer, in the

<PAGE>   4173
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   4174
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42

     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   4177
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   4179
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4184
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4185
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4187
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   4188
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1998 distributions of $0.00 with
     respect to your units due to capital improvements to your partnership's
     property funded from cash flow, distributions with respect to the Preferred
     OP Units and Common OP Units being offered are expected to be      ,
     immediately following the offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   4189
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   4190
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,

     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with
respect to your partnership. In addition, Stanger is entitled to reimbursement
for reasonable legal, travel and out-of-pocket expenses incurred in making the
site visits and preparing the Fairness Opinion, and is entitled to
indemnification against certain liabilities, including certain liabilities under
Federal securities laws. No portion of Stanger's fee is contingent upon
consummation of the offer or the content of Stanger's opinion. Stanger has
performed other services for AIMCO in the past, including: general financial
advisory services relating to a potential acquisition by AIMCO. However, such
acquisition was never completed and no fee was paid to Stanger.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $37,726 in 1996, $39,386 in 1997 and $20,480 for the first
six months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Thurber Manor Associates is a Delaware limited partnership which raised net
proceeds of approximately $1,875,000 in 1984 through a private offering. The
promoter for the private offering of your partnership was Jacques-Miller.
Insignia acquired your partnership in December 1991. AIMCO acquired Insignia in
October, 1998. There are currently a total of 46 limited partners of your
partnership and a total of 18.75 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on July 31, 1984 for the purpose of owning and
operating a single apartment property located in Columbus, Ohio, known as
"Thurber Manor Apartments." Your partnership's property consists of 115
apartment units. The total rentable square footage of your partnership's
property is 104,998 square feet. The average annual rent per apartment unit is
approximately $6,497.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $37,726, $39,386 and $20,480, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2008
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building

partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner will not incur any
liability to your partnership or any other partner for any mistakes or errors in
judgment or for any act or omission believed by it in good faith to be within
the scope of authority conferred upon it by your partnership's agreement of
limited partnership. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will, to the extent permitted by law, indemnify and save
harmless the general partner against and from any personal loss, liability
(including attorneys' fees) or damage incurred by it as the result of any act or
omission in its capacity as general partner unless such loss, liability or
damage results from gross negligence or willful misconduct of the general
partner. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for
 
                                      S-76

tax purposes. However, the general partner of your partnership does not monitor
or regularly receive or maintain information regarding the prices at which
secondary sale transactions in the units have been effectuated. The general
partner of your partnership estimates, based solely on the transfer records of
your partnership (or your partnership's transfer agent), that there have been no
units transferred in sale transactions (excluding transactions believed to be
between related parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

     In addition, an affiliate of AIMCO manages the property of your
partnership. Your partnership has historically paid the property management fees
as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the compensation paid to the property
manager or AIMCO and its affiliates.

                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Thurber Manor
Associates, Limited as of June 30, 1998 and for the six months ended June 30,
1998 and 1997 have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
General Partners
Thurber Manor Associates, Limited:
 
     We have audited the accompanying balance sheets of Thurber Manor
Associates, Limited as of December 31, 1997 and 1996, and the related statements
of operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Thurber Manor Associates,
Limited as of December 31, 1997 and 1996, and the results of its operations and
its cash flows for the years then ended, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Thurber Manor Associates, Limited (the "Partnership") was organized as a
limited partnership under the laws of the State of Delaware pursuant to a
Limited Partnership Agreement and Certificate of Limited Partnership dated
August 13, 1984. The Partnership owns and operates a 115 unit apartment complex,
Thurber Manor Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$54,339 and $65,395, respectively, which are amortized over the term of the
related borrowing. They are shown net of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.

NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership has no administrative or management employees and is
dependent on the Managing General Partner and its affiliates for the management
and administration of all partnership activities. The Partnership is obligated
to pay a property management fee equal to 5% of gross monthly collections. In
addition to the management fee, the partnership agreement provides for payments
to affiliates of a partnership administration fee and reimbursement of certain

General Partners
Thurber Manor Associates, Limited:
 
     We have audited the accompanying balance sheets of Thurber Manor
Associates, Limited as of December 31, 1996 and 1995, and the related statements
of operations and changes in partners' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Thurber Manor Associates,
Limited as of December 31, 1996 and 1995, and the results of its operations and
its cash flows for the years then ended, in conformity with generally accepted
accounting principles.

                           DECEMBER 31, 1996 AND 1995
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Thurber Manor Associates, Limited (the "Partnership") was organized as a
limited partnership under the laws of the State of Delaware pursuant to a
Limited Partnership Agreement and Certificate of Limited Partnership dated
August 13, 1984. The Partnership owns and operates a 115 unit apartment complex,
Thurber Manor Apartments, in Columbus, Ohio.
 
     The Partnership's Managing General Partner is Jacques-Miller Associates, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Depreciation
 
     Depreciation is computed principally by use of the declining balance and
straight-line methods based upon the estimated useful lives of various classes
of assets; buildings are depreciated over 25 years and the personal property
assets are depreciated over a 5 to 10 year period.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 consist of deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Income Taxes
 
     On the basis of legal counsel's opinion, the general partners believe that
the Partnership will be classified as a partnership for Federal income tax
purposes. Accordingly, no provision for income taxes is made in the financial
statements of the Partnership. Taxable income or loss and cash distributions of
the Partnership are allocated in accordance with the partnership agreement and
the Internal Revenue Code and are reportable in the income tax returns of its
partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net income or partners'
deficit as previously reported.

                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4233
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4234
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Villa Nova, Limited Partnership. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   4239
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4240
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0 per unit for the six months ended
     June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL
 
                                       S-3
<PAGE>   4241
 
     TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX
     CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
     TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX
     MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING PROSPECTUS
     AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX
     CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.

<PAGE>   4242
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-[  ] of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4245
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4246
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4247
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4248
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4249
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   4250
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any combination
of such forms of consideration for your units. The offer is made upon the terms

     % Preferred OP Units, Tax-Deferral Common OP Units or cash pursuant to the
offer, you must validly tender and not withdraw your units on or prior to the
Expiration Date. For administrative purposes, the transfer of units tendered
pursuant to the offer will be deemed to take effect as of             , 1998.
 
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent (as defined below), either with
your units to be tendered or in compliance with the specified procedures for
guaranteed delivery of units. If you have units registered in the name of a

wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.
 
     Withdrawal Rights. You may withdraw your tender of units pursuant to the
offer at any time prior to the expiration date of our offer.
 
     Purpose of the Offer. The purpose of our offer is to provide us with an

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby

                                      S-14
<PAGE>   4252
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

Class A Common Stock on the NYSE on a recent date before we commenced this

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   4255
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $20,000
annually for its services as general partner of your partnership and may receive
reimbursement for expenses generated in its capacity as general partner. The
property manager received management fees of $41,083 in 1996, $41,398 in 1997
and $21,568 for the first six months of 1998. We have no current intention of
changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Villa Nova, Limited Partnership is a
Tennessee limited partnership which was formed on April 20, 1984 for the purpose
of owning and operating a single apartment property located in Indianapolis,
Indiana, known as "Villa Nova Apartments". In 1984, it completed a private
placement of units that raised net proceeds of approximately $2,012,500. Villa
Nova Apartments consists of 126 apartment units. Your partnership has no
employees.
 
                                      S-18
<PAGE>   4256
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on July 1, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,359,299, payable to Marine Midland,
Bank of America and FNMA, which bears interest at a rate of 7.60%. The mortgage
debt is due in November 2002. Your partnership also has a second mortgage note
outstanding of $83,835, on the same terms as the first mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4264
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4265
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions of $     with
respect to the Preferred OP Units are $     , current annualized distributions
with respect to the Common OP Units are $2.25, and distributions with respect to
your units for the six months ended June 30, 1998 were $0 per unit. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   4266
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high levels of encumbered properties and material investments in loans
to highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   4267
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units which there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one
 
                                      S-30
<PAGE>   4268
 
       class of outstanding Partnership Preferred Units has prior distribution
       rights and the Tax-Deferral   % Preferred OP Units rank equal to six
       other outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4270
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4271
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   4272
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   4273
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   4274
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or

circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   4278
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   4279
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-42
<PAGE>   4280
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-43
<PAGE>   4281
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   4282
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4288
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4289
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4291
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.

<PAGE>   4292
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June, 1998 were $0 per unit. Therefore, distributions
     with respect to the Preferred OP Units and Common OP Units that we are
     offering are expected to be        , immediately following our offer, than
     the distributions with respect to your units. See "Comparison of Ownership
     of Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   4293
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   4297
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $20,000
for its services as general partner of your partnership and may receive
reimbursement for expenses generated in such capacity. The property manager
received management fees of $41,083 in 1996, $41,398 in 1997 and $21,568 for the
first six months of 1998. The AIMCO Operating Partnership has no current
intention of changing the fee structure for the manager of your partnership
property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Villa Nova Apartments is a Tennessee limited partnership which raised net
proceeds of approximately $2,012,500 in 1984 through a private offering. The
promoter for the private offering of your partnership was Freeman Properties,
Inc. Insignia acquired your partnership in December 1991. AIMCO acquired
Insignia in October, 1998. There are currently a total of 45 limited partners of
your partnership and a total of 35 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on April 20, 1984 for the purpose of owning and
operating a single apartment property located in Indianapolis, Indiana, known as
"Villa Nova Apartments." Your partnership's property consists of 126 apartment
units. The total rentable square footage of your partnership's property is
107,480 square feet. Your partnership's property had an average occupancy rate
of approximately 96.83% in 1996 and 96.83% in 1997. The average annual rent per
apartment unit is approximately $6,232.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $41,083, $41,398 and $21,568, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on July 1, 2015 unless
earlier dissolved. Your partnership has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $2,359,299, payable to Marine Midland, Bank of America and FNMA,
which bears interest at a rate of 7.60%. The mortgage debt is due in November
2002. Your partnership also has a second mortgage note outstanding of $83,835,
on the same terms as the first mortgage note. Your partnership's agreement of
limited partnership also allows the general partner of your partnership to lend
funds to your partnership. Currently, the general partner of your partnership
has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
unaudited financial statements of your partnership included herein.
 
  Results of Operations
 
    Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
    June 30, 1997
 
     Net Income
 
     Your partnership recognized net loss of $52,581 for the six months ended
June 30, 1998, compared to net loss of $6,647 for the six months ended June 30,
1997. The decrease in net income of $45,934, or 691.05% was primarily the result
of an increase in operating expenses. This is discussed in more detail in the
following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$429,544 for the six months ended June 30, 1998, compared to $400,843 for the
six months ended June 30, 1997, an increase of $28,701, or 7.16 %. This increase
was primarily due to an increase in occupancy.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $242,823 for the
six months ended June 30, 1998, compared to $165,512 for the six months ended
June 30, 1997, an increase of $77,311 or 46.71% due to exterior painting
expenses incurred during the first six months of 1998. Management expenses
totaled $21,568 for the six months ended June 30, 1998, compared to $20,186 for
the six months ended June 30, 1997, an increase of $1,382, or 6.85 % which can
be attributed to the increase in revenues as management fees are calculated as a
percentage of revenues.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $20,374 for the six months
ended June 30, 1998 compared to $19,056 for the six months ended June 30, 1997,
an increase of $1,318 or 6.92%. This is primarily due to increased charges
related to collection services fees and other various administrative expenses.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $93,683 for the six months ended June 30, 1998, compared to

31, 1997, compared to a net loss of $85,602 for the year ended December 31,

                                      S-74
<PAGE>   4312
 
7.57%. This increase can be attributed to an increase in occupancy levels
coupled with an increase in rental rates.

received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $386,621 for the
year ended December 31, 1997, compared to $359,373 for the year ended December
31, 1996, an increase of $27,248 or 7.58%. This increase was due to increased
costs associated with non-capitalizable property improvements. Management
expenses totaled $41,398 for the year ended December 31, 1997, compared to

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $62,779 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable, in damages or
otherwise to your partnership or any limited partner for any acts performed by
any of them which are reasonably believed by them to be within the scope of the
authority conferred on them by your partnership's agreement of limited
partnership, excepting only acts of malfeasance, gross negligence or actual
misrepresentation. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest."
 
     The general partner and its affiliate are entitled to indemnification by
your partnership for any and all acts performed by them in good faith belief
that the act or omission was in the best interests of your partnership and which
are reasonably within the scope of the authority conferred upon them by your
partnership's agreement of limited partnership or by your partnership, excepting
only acts of malfeasance, gross negligence or actual misrepresentation;
provided, however, that such indemnity will be paid out of and only to the
extent of partnership assets. As part of its assumption of liabilities in the
consolidation, AIMCO will indemnify the general partner of your partnership and
their affiliates for periods prior to and following the consolidation to the
extent of the indemnity under the terms of your partnership's agreement of
limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not paid any distributions in the last five years.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
 
                                      S-76
<PAGE>   4314
 
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.
 
             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $
million will be required to purchase all of the units sought in the offer, if
such units are tendered for cash. The AIMCO Operating Partnership will obtain
all such funds from cash from operations, equity issuances and short term
borrowings.

          NOTES TO CONDENSED FINANCIAL STATEMENTS -- INCOME TAX BASIS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Villa Nova, Limited as
of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with the accounting basis for federal income tax
reporting. Accordingly, they do not include all the information and footnotes
required by the accounting basis for federal income tax reporting for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1997 AND 1996
                                  (UNAUDITED)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Villa Nova, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated April 23,
1984. The Partnership owns and operates a 126 unit multi-family housing complex,
Villa Nova Apartments in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$47,739 and $57,437, respectively, which are amortized over the term of the
related borrowing. They are shown net of accumulated amortization. Also included
in other assets are syndication costs of $141,727 which are not amortized.

        NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Reclassification
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the
following:

        NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
     The principal balance of the mortgage notes may be prepaid in whole upon
payment of a penalty of the greater of one percent of the unpaid principal
balance at the time of prepayment or the present value of the excess of interest
which would be incurred at the stated rate under the notes over the interest
which would be incurred at the Treasury constant maturity for U.S. Government
obligations.
 
NOTE D -- TRANSACTIONS WITH AFFILIATED PARTIES
 
     The Partnership has no administrative or management employees and is
dependent on the Managing General Partner and its affiliates for the management
and administration of all partnership activities. The Partnership is obligated
to pay a property management fee equal to 5% of gross monthly collections. In
addition to the management fee, the partnership agreement provides for payment
to affiliates of a partnership administration fee and reimbursement of certain
expenses incurred by affiliates on behalf of the Partnership.
 
     Transactions with the Managing General Partner and its affiliates are as

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1996 AND 1995
                                  (UNAUDITED)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Villa Nova, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated April 23,
1984. The Partnership owns and operates a 126 unit multi-family housing complex,
Villa Nova Apartments, in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Residential Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of counsel's opinion, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1996 and 1995 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization. Also included in other assets are syndication costs
of $141,727 which are not amortized.

        NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.
 
  Reclassification
 
     Certain 1995 amounts have been reclassified to conform to the 1996
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1996 and 1995 consist of the
following:

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1995 AND 1994
                                  (UNAUDITED)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Villa Nova, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated April 23,
1984. The Partnership owns and operates a 126 unit multi-family housing complex,
Villa Nova Apartments, in Indianapolis, Indiana.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group ("Insignia"). The property is managed by
Insignia Management Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because on the tax basis (1) certain rental income received in advance
is recorded as income in the year received rather than in the year earned, (2)
buildings and related personal property are depreciated using the lives
specified under the accelerated cost recovery system ("ACRS") or the modified
accelerated cost recovery system ("MACRS") instead of over the estimated lives
of the assets, and (3) syndication costs are not amortized.
 
     On the basis of counsel's opinion, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1995 and 1994 include deferred loan costs
which are amortized over the term of the related borrowing. They are shown net
of accumulated amortization. Also included in other assets are $141,727 of
syndication costs which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers cash and
all highly liquid investments, with an original maturity of three months or less
when purchased, to be cash and cash equivalents.

  Reclassifications

deficit as previously reported.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4342
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4343
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Walker Springs, Limited. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   4348
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4349
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future. Your partnership has not paid any
       distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principle advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   WHAT DISTRIBUTIONS WILL I RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL
       % PREFERRED OP UNITS OR TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $          for the six months ended
     June 30, 1998 (equivalent to $          on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

<PAGE>   4350
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   4351
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4354
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us. Although your
partnership did not make any distributions in 1998, it might make distributions
in the future.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
                                       S-8
<PAGE>   4355
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no
 
                                       S-9
<PAGE>   4356
 
assurance as to our ability to complete future acquisitions. Although we seek
acquisitions and development activities that are accretive on a per share basis,
acquisitions and development activities may fail to perform in accordance with
our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4357
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4358
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 1.01% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least      % of the units of your partnership.
     In the absence of such consent, your only option for liquidation of your
     investment would be to sell your units in a private transaction. Any such
     sale could be at a very substantial discount from your pro rata share of
     the fair market value of your partnership's property and might involve
     significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   4359
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Preferred Partnership Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than Your Partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
                                      S-13
<PAGE>   4360
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.
 
     For a description of certain risks of the offer, see "Risk Factors."
 
TERMS OF THE OFFER

on               , 1998, unless extended.
 
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
 
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions

wish to tender any units pursuant to the offer, you are urged to contact such
person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior

and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) first, all units properly tendered and not
withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
                                      S-15
<PAGE>   4362
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS," "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral      % Preferred OP Units
we are offering for each of your units, we divided the cash offer consideration
by the $100 liquidation preference of each Preferred OP Unit to get        per
unit.
 
     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the
 
                                      S-17
<PAGE>   4364
 
fairness opinion. Based on its analysis, and subject to the assumptions,
limitations and qualifications cited in its opinion, Stanger concluded that our
offer consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $6,000
annually and may receive reimbursement for expenses generated in that capacity.
The property manager received management fees of $46,478 in 1996, $47,212 in
1997 and $23,711 for the first six months of 1998. We have no current intention
of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.

YOUR PARTNERSHIP
 
     Your Partnership and its Property. Walker Springs, Limited is a Tennessee
limited partnership which was formed on May 13, 1982 for the purpose of owning
and operating a single apartment property located in Knoxville, Tennessee, known
as "Walker Springs Apartments". In 1982, it completed a private placement of
units that raised net proceeds of approximately $2,395,000. Walker Springs
Apartments consists of 168 apartment units. Your partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on July 1, 2015, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,540,759, payable to Marine Midland,
Bank of America and FNMA, which bears interest at a rate of 7.60%. The mortgage
debt is due in November 2002. Your partnership also has a second mortgage note
outstanding of $90,284 on the same terms as the first mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4373
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4374
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $       , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the six months ended June, 1998 were $       (equivalent to
$          on an annual basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral OP Common
Units, that you would receive in an exchange for each of your partnership's
units. Therefore distributions with respect to the Preferred OP Units and Common
OP Units that we are offering are expected to be        , immediately following
our offer, than the distributions with respect to your units. See "Comparison of
Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 1.01% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   4376
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least      % of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
                                      S-30
<PAGE>   4377
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your units since the inception of your
       partnership. However, one class of outstanding Partnership Preferred
       Units has prior distribution rights and the Tax-Deferral   % Preferred OP
       Units rank equal to six other outstanding classes of Partnership
       Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your units
       since the inception of your partnership. Historically, the quarterly
       distributions paid on the Common OP Units have been equivalent to the
       dividends paid on AIMCO's Class A Common Stock. We expect this to
       continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4379
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4380
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   4381
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   4382
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
                                      S-36
<PAGE>   4383
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   4384
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units
tendered pursuant to the offer, may postpone the purchase of, and payment for,
units tendered, and may terminate or amend the offer if at any time from or
after           , 1998 and at or before the time of acceptance for payment of
any such units (whether or not any units have theretofore been accepted for

        (f) a tender or exchange offer for any units shall have been commenced

circumstances and each right shall be deemed a continuing right which may be

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
                                      S-40
<PAGE>   4387
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
                                      S-42
<PAGE>   4389
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   4390
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   4391
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             amount payable to the prohibited transferee will be

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4397
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4398
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4400
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.

<PAGE>   4401
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis."
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer."
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and distributions with respect to your units
     for the six months ended June, 1998 were $          (equivalent to
     $          on an annualized basis). This is equivalent to distributions of
     $          per year on the number of Tax-Deferral   % Preferred OP Units,
     or distributions of $          per year on the number of Tax-Deferral
     Common OP Units, that you would receive in exchange for each of your
     partnership's units. Therefore, distributions with respect to the Preferred
     OP Units and Common OP Units that we are offering are expected to be
            , immediately following our offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   4402
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

     performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $6,000
annually and may receive reimbursement for expenses generated in that capacity.
The property manager received management fees of 46,478 in 1996, 47,212 in 1997
and 23,711 for the first six months of 1998. The AIMCO Operating Partnership has
no current intention of changing the fee structure for the manager of your
partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Walker Springs, Limited is a Tennessee limited partnership which raised net
proceeds of approximately $2,395,000 in 1982 through a private offering. The
promoter for the private offering of your partnership was Freeman Properties,
Inc. Insignia acquired your partnership in December 1991. AIMCO acquired
Insignia in October, 1998. There are currently a total of 63 limited partners of
your partnership and a total of 49.5 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 1, 1982 for the purpose of owning and
operating a single apartment property located in Knoxville, Tennessee, known as
"Walker Springs Apartments." Your partnership's property consists of 168
apartment units. The total rentable square footage of your partnership's
property is 176,800 square feet. Your partnership's property had an average
occupancy rate of approximately 94.05% in 1996 and 94.05% in 1997. The average
annual rent per apartment unit is approximately $5,356.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $46,478, $47,212 and $23,711, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on July 1, 2015 unless
earlier dissolved. Your partnership has no present intention to liquidate, sell,
finance or refinance your partnership's property within any specified time
period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $2,540,759, payable to Marine Midland, Bank of America and FNMA,
which bears interest at a rate of 7.60%. The mortgage debt is due in November
2002. Your partnership also has a second mortgage note outstanding of $90,284 on
the same terms as the first mortgage note. Your partnership's agreement of
limited partnership also allows the general partner of your partnership to lend
funds to your partnership. Currently, the general partner of your partnership
has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

result of increased operating expenses.

in operating expense is due mainly to increases in non-capitalizable property
improvements, including interior painting. Management expenses totaled $23,711

ended June 30, 1997, an increase of $816, or 3.56,%.

ended June 30, 1998 compared to $13,968 for the six months ended June 30, 1997,
an increase of $3,319 or 23.76%. The increase is primarily due to an increase in
non-capitalizable personal computer costs.

costs, totaled $100,888 for the six months ended June 30, 1998, compared to

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $131,607 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partners of your partnership and
their affiliates are not liable, responsible or accountable, in damages or
otherwise to your partnership or any limited partner for any acts performed by
any of them which are reasonably believed by them to be within the scope of the
authority conferred on them by your partnership's agreement of limited
partnership, excepting only acts of malfeasance, gross negligence or actual
misrepresentation. As a result, unitholders might have a more limited right of
action in certain circumstances than they would have in the absence of such a
provision in your partnership's agreement of limited partnership. The general
partner of your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partners and their affiliates are entitled to indemnification
by your partnership for any and all acts performed by them which are reasonably
within the scope of the authority conferred upon them by your partnership's
agreement of limited partnership or by your partnership, excepting only acts of
malfeasance, gross negligence or actual misrepresentation; provided, however,
that such indemnity will be paid out of and only to the extent of partnership
assets. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     Your partnership has not made any distributions in the last five years. The
original cost per unit was $68,429.
 
  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions

limited to, contracts, arrangements, understandings or relationships concerning
transfer or voting thereof, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss or the giving or withholding
of proxies.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Walker Springs, Limited
as of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 1997. It should be
understood that the accounting measurements at interim dates inherently involve
greater reliance on estimates than at year-end. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
year.

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1997 AND 1996
                                  (UNAUDITED)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Walker Springs, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated May 13, 1982.
The Partnership owns and operates a 168 unit apartment complex, Walker Springs
Apartments, in Knoxville, Tennessee.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The property is
managed by Insignia Residential Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present the
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because, on the tax basis (1) certain rental income received in
advance is recorded as income in the year received rather than in the year
earned, (2) buildings and related personal property are depreciated using the
lives specified under the accelerated cost recovery system ("ACRS") or the
modified accelerated cost recovery system ("MACRS") instead of over the
estimated lives of the assets, and (3) syndication costs are not amortized.
 
     On the basis of Treasury Regulations, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 31, 1997 and 1996 include deferred loan costs of
$74,257 and $89,362, respectively, which are amortized over the term of the
related borrowing. They are shown net of accumulated amortization. Also included
in other assets are syndication costs of $108,968 which are not amortized.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.

        NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS -- (CONTINUED)
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Reclassifications
 
     Certain 1996 amounts have been reclassified to conform to the 1997
presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.
 
NOTE B -- RESTRICTED ESCROWS
 
     Restricted escrow deposits at December 31, 1997 and 1996 consist of the
following:

Reserve Escrow -- A portion of the proceeds of the 1992 loan
  refinancing was placed into a reserve escrow. The funds
  are used for certain repair work, debt service, expenses
  and property taxes or insurance. The funds in the reserve
  escrow exceed the minimum balance required to be
  maintained by the lender during the term of the loan. ....  $177,053    $169,775

               NOTES TO FINANCIAL STATEMENTS -- INCOME TAX BASIS
                           DECEMBER 31, 1996 AND 1995
                                  (UNAUDITED)
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Walker Springs, Limited (the "Partnership") was organized as a limited
partnership under the laws of the State of Tennessee pursuant to a Limited
Partnership Agreement and Certificate of Limited Partnership dated May 13, 1982.
The Partnership owns and operates a 168 unit apartment complex, Walker Springs
Apartments, in Knoxville, Tennessee.
 
     The Partnership's Managing General Partner is Davidson Properties, an
affiliate of Insignia Financial Group, Inc. ("Insignia"). The Property is
managed by Insignia Management Group, an affiliate of Insignia.
 
  Basis of Accounting
 
     The financial statements are prepared on the basis used in the preparation
of the Partnership's Federal income tax return and do not purport to present the
financial position and results of operations in accordance with generally
accepted accounting principles ("GAAP"). The tax basis used differs from GAAP
primarily because, on the tax basis (1) certain rental income received in
advance is recorded as income in the year received rather than in the year
earned, (2) buildings and related personal property are depreciated using the
lives specified under the accelerated cost recovery system ("ACRS") or the
modified accelerated cost recovery system ("MACRS") instead of over the
estimated lives of the assets, and (3) syndication costs are not amortized.
 
     On the basis of counsel's opinion, the general partners believe that the
Partnership will be classified as a partnership for Federal income tax purposes.
Accordingly, no provision for income taxes is made in the financial statements
of the Partnership. Taxable income or loss and cash distributions of the
Partnership are allocated in accordance with the partnership agreement and the
Internal Revenue Code and are reportable in the income tax returns of its
partners. The Partnership's tax returns are subject to examination by Federal
and state taxing authorities. Because many types of transactions are susceptible
to varying interpretations under Federal and state income tax laws and
regulations, the amounts reported in the accompanying financial statements may
be subject to change at a later date upon final determination by the respective
taxing authorities.
 
  Depreciation
 
     Depreciation is provided for in amounts sufficient to allocate the cost of
depreciable assets to operations over lives in accordance with the applicable
statutory recovery methods, generally ACRS and MACRS, using the straight-line
and accelerated methods on both real and personal property. Under generally
accepted accounting principles, the cost of depreciable assets would be
allocated systematically over their estimated useful lives.
 
  Other Assets
 
     Other assets at December 1, 1996 and 1995 include deferred loan costs which
are amortized over the term of the related borrowing. They are shown net of
accumulated amortization. Also included in other assets are syndication costs of
$108,968 which are not amortized and prepaid utility deposits of $2,500.
 
  Cash and Cash Equivalents
 
     For purposes of reporting cash flows, the Partnership considers
unrestricted cash and unrestricted highly liquid investments, with an original
maturity of three months or less when purchased, to be cash and cash
equivalents.

  Reclassifications

presentation. These reclassifications had no impact on net loss or partners'
deficit as previously reported.

of interest which would be incurred at the stated rate under the notes over the
interest which would be incurred at the Treasury constant maturity for U.S.
Government obligations.

     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4446
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4447
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Wingfield Investors Limited Partnership. For each unit that you tender, you
     may choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),

     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto

     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.

<PAGE>   4452
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4453
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $594.00 per unit for the six months
     ended June 30, 1998 (equivalent to $1,188 on an annual basis). We will pay
     fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.

<PAGE>   4455
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4458
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4459
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4460
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4461
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4462
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   4463
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;

                                      S-14
<PAGE>   4465
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
 
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions, liquidity and
transfer and redemption rights. See "Comparison of Preferred OP Units and Class
I Preferred Stock" for a chart highlighting such differences.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
 
                                      S-15
<PAGE>   4466
 
     exchange of your units for cash and OP Units will be treated, for Federal
income tax purposes, as a partial sale of such units for cash and as a partial
tax-free contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT
AND "FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS", "FEDERAL INCOME
TAXATION OF THE AIMCO OPERATING PARTNERSHIP AND OP UNITHOLDERS" AND "OTHER TAX
CONSEQUENCES" IN THE ACCOMPANYING PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A
FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs and the decline in the availability of commercial
mortgaging financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

     In order to determine the number of Tax-Deferral Common OP Units we are
offering for each of your units, we divided the cash offer consideration by
$     to get      per unit. This price represents the closing price of AIMCO's
Class A Common Stock on the NYSE on a recent date before we commenced this
offer.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive fees for additional services
of your partnership but may receive reimbursement for expenses generated in that
capacity. The property manager received management fees of $36,670 in 1996,
$39,358 in 1997 and $20,365 for the first six months of 1998. We have no current
intention of changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management. we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Wingfield Investors Limited Partnership
is a Kansas limited partnership which was formed on January 25, 1990 for the
purpose of owning and operating a single apartment
 
                                      S-18
<PAGE>   4469
 
property located in Olathe, Kansas, known as "Wingfield Apartments". In 1990, it
completed a private placement of units that raised net proceeds of approximately
$1,010,350. Wingfield Apartments consists of 131 apartment units. Your
partnership has no employees.
 
     Property Management. Since December 1990, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2020, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,436,765, payable to FNMA, which bears
interest at a rate of 7.83%. The mortgage debt is due in October 2003. Your
partnership also has a second mortgage note outstanding of $79,560, on the same
terms as the first mortgage note. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4477
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4478
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $  , current annualized distributions with respect
to the Common OP Units are $2.25, and distributions with respect to your units
for the six months ended June 30, 1998 were $594 per unit (equivalent to $1,188
on an annualized basis). This is equivalent to distributions of $          per
year on the number of Tax-Deferral      % Preferred OP Units, or distributions
of $          per year on the number of Tax-Deferral Common OP Units, that you
would receive in exchange for each of your partnership's units. Therefore,
distributions with respect to the Preferred OP Units and Common OP Units that we
are offering are expected to be        , immediately following our offer, than
the distributions with respect to your units. See "Comparison of Ownership of
Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   4480
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   4481
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the interest paid on AIMCO's Class A Common
       Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4483
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4484
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   4485
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   4486
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

<PAGE>   4487
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   4488
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   4491
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   4493
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   4494
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   4495
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   4496
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                                                             sale by the AIMCO Operating Partnership of partnership

                                                             or not such sale occurs concurrently with such

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4501
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4502
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4504
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   4505
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $  , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions of with respect to your units
     for the six months ended June 30, 1998 were $594 per unit (equivalent to
     $1,188 on an annualized basis). This is equivalent to distributions of
     $          per year on the number of Tax-Deferral      % Preferred OP
     Units, or distributions of $          per year on the number of Tax-
     Deferral Common OP Units, that you would receive in exchange for each of
     your partnership's units. Therefore, distributions with respect to the
     Preferred OP Units and Common OP Units that we are offering are expected to
     be        , immediately following our offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   4506
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

     performed a site inspection of your partnership's property, reviewed local
real estate market conditions, and discussed with property management personnel
conditions in local apartment rental markets and market conditions for sales and
acquisitions of properties similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information
 
                                      S-59

     contained in this Prospectus Supplement or that were provided, made
available, or otherwise communicated to Stanger by your partnership, AIMCO, or
the management of the partnership's property. Stanger has not performed an
independent appraisal, engineering study or environmental study of the assets
and liabilities of your partnership. Stanger relied upon the representations of
your partnership and AIMCO concerning, among other things, any environmental
liabilities, deferred maintenance and estimated capital expenditure and
replacement reserve requirements, the determination and valuation of non-real
estate assets and liabilities of your partnership, the allocation of your
partnership's net values between the general partner, special limited partner
and limited partners of your partnership, the terms and conditions of any debt
encumbering the partnership's property, and the transaction costs and fees
associated with a sale of the property. Stanger also relied upon the assurance
of your partnership, AIMCO, and the management of the partnership's property
that any financial statements, budgets, pro forma statements, projections,
capital expenditure estimates, debt, value estimates and other information
contained in this Prospectus Supplement or provided or communicated to Stanger
were reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the value of the
partnership's property or other balance sheet assets and liabilities or other
information reviewed between the date of such information provided and the date
of the Fairness Opinion; that your partnership, AIMCO, and the management of the
partnership's property are not aware of any information or facts that would
cause the information supplied to Stanger to be incomplete or misleading; that
the highest and best use of the partnership's property is as improved; and that
all calculations were made in accordance with the terms of your partnership's
agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity and fees for additional
services. The property manager received management fees of $36,670 in 1996,
$39,358 in 1997 and $20,365 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Wingfield Investors Limited Partnership is a Kansas limited partnership
which raised net proceeds of approximately $1,010,350 in 1990 through a private
offering. The promoter for the private offering of your partnership was Waddell
& Reed, Inc. Insignia acquired your partnership in December 1990. AIMCO acquired
Insignia in October, 1998. There are currently a total of 42 limited partners of
your partnership and a total of 50 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on January 25, 1990 for the purpose of owning
and operating a single apartment property located in Olathe, Kansas, known as
"Wingfield Apartments." Your partnership's property consists of 131 apartment
units. The total rentable square footage of your partnership's property is
87,317 square feet. Your partnership's property had an average occupancy rate of
approximately 96.95% in 1996 and 96.95% in 1997. The average annual rent per
apartment unit is approximately $5,618.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1990, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $36,670, $39,358 and $20,365, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2020
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $2,436,765, payable to FNMA, which bears interest at a rate of
7.83%. The mortgage debt is due in October 2003. Your partnership also has a
second mortgage note outstanding of $79,560, on the same terms as the current
mortgage note. Your partnership's agreement of limited partnership also allows
the general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the doing of any act or the failure to do any
act by the general partner, which does not constitute fraud, gross negligence or
willful malfeasance as determined a court of competent jurisdiction, pursuant to
the authority granted to it to promote the interests of your partnership, the
effect of which causes or results in loss or damage to your partnership, if done
in good faith, will not subject the general partner or its affiliates to any
liability. As a result, unitholders might have a more limited right of action in
certain circumstances than they would have in the absence of such a provision in
your partnership's agreement of limited partnership. The general partner of your
partnership is owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will also indemnify and hold harmless the general partners
and their affiliates from any claim, loss, expense, liability, action or damage
resulting from any act or omission done in good faith which do not constitute
fraud, gross negligence or willful malfeasance as determined by a court of
competent jurisdiction pursuant to the authority granted to it to promote the
interests of your partnership, including, without limitation, reasonable fees
and expenses of attorneys engaged by the general partner in defense of such act
or omission and other reasonable costs and expenses of litigation and appeal.
All costs and expenses incurred in defending any proceeding or action or
otherwise will be advanced by your partnership. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Wingfield Investors
Limited Partnership as of June 30, 1998 and for the six months ended June 30,
1998 and 1997 have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Wingfield Investors Limited Partnership
(A Kansas Limited Partnership):
 
     We have audited the accompanying balance sheet of Wingfield Investors
Limited Partnership (a Kansas Limited Partnership) (the "Partnership") as of
December 31, 1997 and 1996, and the related statements of operations, changes in
partners' deficit, and cash flows for each of the two years in the period ended
December 31, 1997. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Partnership as of December 31, 1997, and
the results of its operations and its cash flows for each of the two years in
the period ended December 31, 1997 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1997 AND 1996
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Wingfield Investors Limited Partnership (a Kansas Limited Partnership) (the
"Partnership") was formed to acquire, own and operate Wingfield Apartments, a
131-unit multifamily residential complex located in Olathe, Kansas. The general
partner of the Partnership is United Investors Real Estate, Inc., a Delaware
corporation.
 
  Basis of Accounting
 
     The accompanying financial statements of the Partnership are prepared on
the accrual basis and, therefore, revenue is recorded as earned and costs and
expenses are recorded as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash
 
     Cash and cash equivalents includes cash on hand and in banks, money market
funds and certificates of deposit with original maturities of less than three
months.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the leases and such deposits are included in receivables and deposits. The
security deposits are refunded when the tenant vacates, provided the tenant has
not damaged its space and is current on its rental payments.
 
  Income Taxes
 
     For income tax purposes, the Partnership reports revenue and costs and
expenses on the accrual method. No income tax provisions have been shown in the
accompanying statements of operations since the partners are taxed individually.
 
  Investment Properties
 
     Investment properties are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over estimated useful
lives of fifteen to forty years for buildings and improvements and five to
twelve years for furniture and fixtures.
 
     The Partnership records impairment losses on long-lived assets used in
operations when events and circumstances indicate that the assets might be
impaired and the undiscounted cash flows estimated to be generated by those
assets are less than the carrying amounts of those assets.
 
  Other Assets
 
     Included in other assets are deferred charges which consist of loan costs
totaling $126,685 which are amortized over the terms of the related notes.
Accumulated amortization as of December 31, 1997 was $52,757.

  Advertising
 
     The Partnership expenses the costs of advertising as incurred. Advertising
expense, included in operating expenses, was $25,586 and $15,099 for the years
ended December 31, 1997 and 1996, respectively.
 
  Reclassifications
 
     Certain reclassifications of prior year balances have been made to conform
to the current year's presentation.

Property management fees....................................  $39,358    $36,670
Reimbursement of expenses...................................   15,852     15,756
</TABLE>
 
     In addition, affiliates of the general partner were paid $13,843 and
$12,378 during 1997 and 1996, respectively, for construction oversight costs
incurred in conjunction with the Partnership's capital improvement and major
repair projects.
 
     For the period from January 1, 1996 to August 31, 1997, the Partnership
insured Wingfield Apartments under a master policy through an agency and insurer
unaffiliated with the general partner. An affiliate of the general partner
acquired, in the acquisition of a business, certain financial obligations from
an insurance agency which was later acquired by the agent who placed the master
policy. The agent assumed the financial obligations to the affiliate of the
general partner, who received payments on these obligations from the agent. The
amount of the Partnership's insurance premiums that accrued to the benefit of
the affiliate of the general partner by virtue of the agent's obligations was
not significant.

     On March 17, 1998, Insignia Financial Group, Inc. ("Insignia") entered into
an agreement to merge its national residential property management operations,
and its controlling interest in Insignia Properties Trust, with Apartment
Investment and Management Company ("AIMCO"), a publicly traded real estate
investment trust. The closing, which is anticipated to happen in the third
quarter of 1998, is subject to customary conditions, including government
approvals and the approval of Insignia's shareholders. If the closing occurs,
AIMCO will then control the general partner of the Partnership.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Wingfield Investors Limited Partnership (A Kansas Limited Partnership) (the
"Partnership") was formed to acquire, own and operate Wingfield Apartments, a
131-unit multifamily residential complex located in Olathe, Kansas. The general
partner of the Partnership is United Investors Real Estate, Inc., a Delaware
corporation.
 
  Basis of Accounting
 
     The accompanying financial statements of the Partnership are prepared on
the accrual basis and, therefore, revenue is recorded as earned and costs and
expenses are recorded as incurred.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash
 
     Cash and cash equivalents includes cash on hand and in banks, money market
funds and certificates of deposit with original maturities of less than three
months.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are considered restricted cash. Deposits are
refunded when the tenant vacates, provided the tenant has not damaged its space
and is current on its rental payments.
 
  Income Taxes
 
     For income tax purposes, the Partnership reports revenue and costs and
expenses on the accrual method. No income tax provisions have been shown in the
accompanying statements of operations since the partners are taxed individually.
 
  Apartment Properties
 
     Apartment properties are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over estimated useful
lives of fifteen to forty years for buildings and improvements and five to
twelve years for furniture and fixtures.
 
     During 1995, the Partnership adopted Statement of Financial Accounting
Standards ("SFAS") No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of, which requires impairment losses to
be recognized for long-lived assets used in operations when indicators of
impairment are present and the undiscounted cash flows are not sufficient to
recover the assets' carrying amounts. The impairment loss is measured by
comparing the fair value of the asset to its carrying amount. The adoption of
SFAS No. 121 had no effect on the Partnership's financial statements.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Deferred Charges
 
     Deferred charges consist of loan costs which are amortized over the terms
of the related notes.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred. Advertising
expense, included in operating expenses, was $15,099 and $10,034 for the years
ended December 31, 1996 and 1995, respectively.
 
  Reclassifications
 
     Certain reclassifications of prior year balances have been made to conform
to the current year's presentation.

     During the years ended December 31, 1996 and 1995 the Partnership paid the
following amounts to affiliates of the general partner:

                                                              -------    -------

Property management fees....................................  $36,670    $35,097
Reimbursement of expenses...................................   15,756     15,000
</TABLE>
 
     In addition, affiliates of the general partner were paid $12,378 and $9,269
during 1996 and 1995, respectively, for construction oversight costs incurred in
conjunction with the Partnership's capital improvement and major repair
projects.
 
     The Partnership insures Wingfield Apartments under a master policy through
an agency and insurer unaffiliated with the general partner. An affiliate of the
general partner acquired, in the acquisition of a business, certain financial
obligations from an insurance agency which was later acquired by the agent who
placed the current year's master policy. The current agent assumed the financial
obligations to the affiliate of the general partner, who receives payments on
these obligations from the agent. The amount of the Partnership's insurance
premiums accruing to the benefit of the affiliate of the general partner by
virtue of the agent's obligations is not significant.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4554
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4555
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Winrock-Houston Limited Partnership. For each unit that you tender, you may
     choose to receive                of our Tax-Deferral      % Partnership
     Preferred Units (also referred to as "Preferred OP Units"),
     of our Tax-Deferral Partnership Common Units (also referred to as "Common
     OP Units"), or $          in cash (subject, in each case to adjustment for
     any distributions paid to you during the offer period). If you like, you
     can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,054 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   4560
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4561
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0.00 per unit for the six months
     ended June 30, 1998. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   4562
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.

<PAGE>   4563
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4566
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4567
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4568
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4569
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4570
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 35.40% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   4571
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Preferred OP Units has prior
       distribution rights and the Tax-Deferral   % Preferred OP Units rank
       equal to six other outstanding classes of Preferred OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

on               , 1998, unless extended.

person promptly.
 
     Proration. If the number of units properly tendered and not withdrawn prior

who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,

<PAGE>   4573
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN OF THIS

YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

Class A Common Stock on the NYSE on a recent date before we commenced this

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   4576
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, unlike the general partner of the AIMCO Operating Partnership,
the partner of your partnership is entitled to compensation for its services as
general partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $50,000
beginning in 1988 (which was paid pro rata for October through December only),
increasing annually at a rate of 6% beginning in 1989 for its services as
general partner and may receive reimbursement for expenses generated in that
capacity. The property manager received management fees of $449,997 in 1996 and
$215,747 for the first six months of 1998. We have no current intention of
changing the fee structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Winrock-Houston Limited Partnership is a
Delaware limited partnership which was formed on July 13, 1988 for the purpose
of owning and operating a small number of apartment properties located in
Houston, Texas, known as "Briarwest Apartments," "Briarwood Apartments,"
"Westgate Apartments" and "Barcelona Apartments". In 1987, it completed a
private placement of units that raised net proceeds of approximately
$25,000,000. Barcelona Apartments consists of 126 apart-
 
                                      S-18
<PAGE>   4577
 
ment units, Briarwest Apartments consists of 380 apartment units, Briarwood
Apartments consists of 351 apartment units and Westgate Apartments consists of
313 apartment units. Your partnership has no employees.
 
     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2037, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage notes outstanding on Barcelona Apartments of $2,404,552,
Briarwest Apartments of $7,233,295 and Briarwood Apartments of $5,077,447
payable to IDS Life Insurance Co., which bear interest at a rate of 7.88%. Such
mortgage notes are due February 2006. There is also a mortgage note on Westgate
Apartments, the balance of which is $6,078,087, as of June 30, 1998. The note is
payable to Reilly Mortgage Co., bears interest at 7.50% and is due February
2006. Your partnership's agreement of limited partnership also allows the
general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4585
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4586
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units of $2.25, and the 1998 distributions of
$0.00 with respect to your units, distributions with respect to the Preferred OP
Units and Common OP Units that we are offering are expected to be        ,
immediately following our offer, than the distributions with respect to your
units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   4587
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 35.40% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   4588
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
                                      S-30
<PAGE>   4589
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis).Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4591
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4592
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   4593
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
  Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   4594
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
                                      S-36
<PAGE>   4595
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.

     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     that any debt of your partnership or any of its subsidiaries secured by any

        (f) a tender or exchange offer for any units shall have been commenced

circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   4599
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any
 
                                      S-42
<PAGE>   4601
 
     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   4602
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or

     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4609
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4610
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4612
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.

     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1998 distributions of $0.00 with
     respect to your units, distributions with respect to the Preferred OP Units
     and Common OP Units being offered are expected to be      , immediately
     following the offer, than the distributions with respect to your units. See
     "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   4614
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not
 
                                      S-58
<PAGE>   4617
 
     limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of your partnership, the allocation of your partnership's net values
between the general partner, special limited partner and limited partners of
your partnership, the terms and conditions of any debt encumbering the
partnership's property, and the transaction costs and fees associated with a
sale of the property. Stanger also relied upon the assurance of your
partnership, AIMCO, and the management of the partnership's property that any
financial statements, budgets, pro forma statements, projections, capital
expenditure estimates, debt, value estimates and other information contained in
this Prospectus Supplement or provided or communicated to Stanger were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of your partnership's agreement of
limited partnership, and reflect the best currently available estimates and good
faith judgments; that no material changes have occurred in the
 
                                      S-59
<PAGE>   4618
 
     value of the partnership's property or other balance sheet assets and
liabilities or other information reviewed between the date of such information
provided and the date of the Fairness Opinion; that your partnership, AIMCO, and
the management of the partnership's property are not aware of any information or
facts that would cause the information supplied to Stanger to be incomplete or
misleading; that the highest and best use of the partnership's property is as
improved; and that all calculations were made in accordance with the terms of
your partnership's agreement of limited partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.
 
COMPENSATION AND MATERIAL RELATIONSHIPS
 
     Stanger has been retained by AIMCO to provide fairness opinions with
respect to your partnership and other partnerships which are or will be the
subject of similar offers. Stanger will be paid a fee by AIMCO of $9,000 with
respect to your partnership. In addition, Stanger is entitled to reimbursement
for reasonable legal, travel and out-of-pocket expenses incurred in making the

Federal securities laws. No portion of Stanger's fee is contingent upon
consummation of the offer or the content of Stanger's opinion. Stanger has

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $50,000
beginning in 1988 (which was paid pro rata for October through December only),
increasing annually at a rate of 6% beginning in 1989 in its capacity as general
partner of your partnership and may receive reimbursement for expenses generated
in such capacity. The property manager received management fees of $449,997 in
1996 and $215,747 for the first six months of 1998. The AIMCO Operating
Partnership has no current intention of changing the fee structure for the
manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Winrock-Houston Limited Partnership is a Delaware limited partnership which
raised net proceeds of approximately $25,000,000 in 1987 through a private
offering. The promoter for the private offering of your partnership was Winthrop
Securities Co., Inc. Insignia acquired your partnership in November 1997. AIMCO
acquired Insignia in October, 1998. There are currently a total of 159 limited
partners of your partnership and a total of 250 units of your partnership
outstanding. Your partnership is in the business of owning and managing
residential housing. Currently, your partnership owns and manages the small
number of apartment properties described below. Your partnership has no
employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on July 13, 1988 for the purpose of owning and
operating a small number of apartment properties located in Houston, Texas,
known as "Briarwest Apartments," "Briarwood Apartments," "Westgate Apartments"
and "Barcelona Apartments". In Barcelona Apartments, there are 126 apartment
units. The total rentable square footage is 115,591 square feet and the average
annual rent per apartment unit is $6,639. There are 380 apartment units in
Briarwest Apartments. The total rentable square footage is 344,405 square feet
and the average annual rent per apartment unit is $6,446. Briarwood Apartments
has 351 apartment units. The total rentable square footage is 280,705 square
feet. The average annual rent per apartment unit is $6,595. In Westgate
Apartments, there are 313 apartment units. The total rentable square footage is
279,101 square feet and the average annual rent per apartment unit is $7,324.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996 and the first six months of
1998 were $449,997 and $215,747, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2037
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.

<PAGE>   4630
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage
notes outstanding on Barcelona Apartments of $2,404,552, Briarwest Apartments of
$7,233,295 and Briarwood Apartments of $5,077,447 payable to IDS Life Insurance
Co., which bear interest at a rate of 7.88%. Such mortgage notes are due
February 2006. There is also a mortgage note on Westgate Apartments, the balance
of which is $6,078,087, as of June 30, 1998. The note is payable to Reilly
Mortgage Co., bears interest at 7.50% and is due February 2006. Your
partnership's agreement of limited partnership also allows the general partner
of your partnership to lend funds to your partnership. Currently, the general
partner of your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the
audited financial statements of your partnership included herein. Due to this
partnership being a recent acquisition, very little discussion is available for
variances.
 
  Results of Operations
 
     Six Months Ended June 30, 1998
Due to this partnership being a recent acquisition, no data was available for
the six months ended June 30, 1997.
 
     Net Income
 
     Your Partnership recognized net income of $1,871,786 for the six months
ended June 30, 1998.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$4,404,469 for the six months ended June 30, 1998.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $1,871,786 for
the six months ended June 30, 1998. Management expenses totaled $215,747 for the
six months ended June 30, 1998.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $217,194 for the six months
ended June 30, 1998.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $867,215 for the six months ended June 30, 1998.
 
     Comparison of the Year Ended December 31, 1997 to the Year Ended December
31, 1996
 
     Net Income
 
     Your partnership recognized net income of $244,000 for the year ended
December 31, 1997, compared to a net loss of $50,000 for the year ended December
31, 1996. The increase in net income of $294,000 was primarily the result of an
increase in revenues, offset by an increase in operating expenses.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$8,314,000 for the year ended December 31, 1997, compared to $7,638,000 for the
year ended December 31, 1996, an increase of $676,000, or 8.85% due mainly to an
increase in rental rates at the partnership's four properties
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $3,967,000 for
the year ended December 31, 1997, compared to $3,636,000 for the year ended
December 31, 1996, an increase of $331,000 or 9.10%. Management expenses totaled
$407,000 for the year ended December 31, 1997, compared to $377,000 for the year
ended December 31, 1996, an increase of $30,000, or
 
                                      S-74
<PAGE>   4633
 
     7%. The increase is due to the increase in rental revenue, as management
fees are calculated based on a percentage of revenue. The increase in operating
expenses is due to increased utility costs at Briarwest and increased payroll
related costs at all of the partnership's properties.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $371,000 for the year ended
December 31, 1997 compared to $439,000 for the year ended December 31, 1996, a
decrease of $68,000 or 15.49%. This decrease is primarily attributable to higher
than normal legal fees during 1996.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $1,729,000 for the year ended December 31, 1997, compared to
$1,722,000 for the year ended December 31, 1996, an increase of $7,000, or .41%.
 
     Comparison of the Year Ended December 31, 1996 to the Year Ended December
31, 1995
 
     Net Income
 
     Your partnership recognized a net loss of $50,000 for the year ended
December 31, 1996, compared to net income of $935,508 for the year ended
December 31, 1995. The decrease in net income of $985,261, or 105.32% was
primarily the result of an increase in interest expense. These factors are
discussed in more detail in the following paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$7,638,000 for the year ended December 31, 1996, compared to $7,416,230 for the
year ended December 31, 1995, an increase of $221,731, or 2.99%.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $3,636,000 for
the year ended December 31, 1996, compared to $3,469,641 for the year ended
December 31, 1995, an increase of $166,359 or 4.79%. Management expenses totaled
$377,058 for the year ended December 31, 1996, compared to $364,696 for the year
ended December 31, 1995, an increase of $12,362, or 3.39%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $439,000 for the year ended
December 31, 1996 compared to $769,923 for the year ended December 31, 1995, a
decrease of $330,923 or 42.98%.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $1,722,000 for the year ended December 31, 1996, compared to
$249,645 for the year ended December 31, 1995, an increase of $1,472,355, or
589.78%. The increase is attributable to the partnership securing approximately
$19 million of new debt during 1996.
 
     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $1,000,132 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on
 
                                      S-75
<PAGE>   4634
 
     outstanding debt, capital improvements, and distributions paid to limited
partners. Your partnership has adequate sources of cash to finance its
operations, both on a short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates who perform services on behalf of your partnership will not incur
any liability, responsibility or accountability for damages or otherwise to your
partnership or any limited partner arising out of any acts performed or any
omission by any of them if they believed in good faith that such act or omission
was in the best interests of your partnership and such course of conduct did not
constitute negligence or misconduct on the part of the such person. As a result,
unitholders might have a more limited right of action in certain circumstances
than they would have in the absence of such a provision in your partnership's
agreement of limited partnership. The general partner of your partnership is
owned by AIMCO. See "Conflicts of Interest".
 
     Your partnership will indemnify and save harmless the general partner and
its affiliates who perform services on behalf of your partnership against any
loss, damage, liability, cost or expenses (including reasonable attorneys' fees)
incurred by them in connection with your partnership provided that they have
determined in good faith that the course of conduct which caused the loss,
damage, liability, cost or expense was in the best interests of your partnership
and was not the result of negligence or misconduct on the part of such persons.
Such indemnity will be paid from, an only to the extent of, partnership assets.
However, the general partner, its affiliates and any placing broker will be
liable and not be indemnified from any loss, damage or cost resulting form the
violation of any Federal or state securities law in connection with the sale of
units unless (i) there has been a successful adjudication on the merits of each
count involving such securities law violation and the court approves the
indemnification of litigation costs, (ii) such claims have been dismissed with
prejudice on the merits by a court of competent jurisdiction and the court
approves the indemnification of litigation costs or (iii) a court of competent
jurisdiction approves a settlement of such claim and the court approves the
indemnification of litigation costs. In such claim for indemnification for
Federal or state securities law violation, the party seeking indemnification
must place before the court the position of the SEC and any other applicable
regulatory agency with respect of the issue of indemnification for securities
law violations. As part of its assumption of liabilities in the consolidation,
AIMCO will indemnify the general partner of your partnership and their
affiliates for periods prior to and following the consolidation to the extent of
the indemnity under the terms of your partnership's agreement of limited
partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. The
original cost per unit was $500,000.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that there
have been no units transferred in sale transactions (excluding transactions
believed to be between related parties, family members or the same beneficial
owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

as described in the following table:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation and distributions that would have
been paid to the general partner of your partnership, or the company paid to the
property manager or AIMCO and its affiliates.

             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Winrock-Houston Limited
Partnership as of June 30, 1998 and for the six months ended June 30, 1998 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Winrock-Houston Limited Partnership:
 
     We have audited the accompanying consolidated balance sheets of
Winrock-Houston Limited Partnership (the "Partnership") as of December 31, 1997
and 1996, and the related consolidated statements of operations, partners'
equity and cash flows for the years then ended. These financial statements are
the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Winrock-Houston Limited
Partnership as of December 31, 1997 and 1996, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996
 
NOTE 1 -- ORGANIZATION
 
     Winrock-Houston Limited Partnership (the "Partnership") was formed on July
21, 1988 under the laws of the State of Delaware for the purpose of acquiring a
general and limited partnership interest in Winrock-Houston Associates Limited
Partnership, a Delaware limited partnership (the "Operating Partnership"). The
Operating Partnership was formed to acquire, renovate and operate four separate,
but nearly contiguous, apartment complexes located in Houston, Texas (the
"Properties"). The Partnership owns a combined 80% general and limited
partnership interest in the Operating Partnership. Winrock-Houston Joint
Venture, a Maryland general partnership, owns a combined 20% general and limited
partnership interest in the Operating Partnership. The general partner of the
Partnership is First Winthrop Corporation ("FWC" or the "General Partner"). The
Partnership will terminate on December 31, 2037, or earlier upon the occurrence
of certain events specified in the partnership agreement.
 
     On October 28, 1997, Insignia Financial Group, Inc. ("Insignia") acquired
100% of the Class B stock of FWC. Pursuant to this transaction, Insignia has the
right to appoint the members of a Residential Committee. The Residential
Committee effectively controls the activities of the Partnership.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The accompanying consolidated financial statements include the accounts of
the Partnership and the Operating Partnership prepared on the accrual basis of
accounting in accordance with generally accepted accounting principles.
Winrock-Houston Joint Venture's ownership interest in the Operating Partnership
has been reflected as a minority interest in the accompanying consolidated
balance sheets and statements of operations. All significant intercompany
accounts and transactions have been eliminated in consolidation.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Investment Properties
 
     Investment properties are stated at cost. The Operating Partnership records
impairment losses on long-lived assets used in operations when events and
circumstances indicate that the assets might be impaired and the undiscounted
cash flows estimated to be generated by those assets are less than the carrying
amounts of those assets.
 
  Depreciation
 
     The Partnership and the Operating Partnership depreciate real property
using the straight-line method over a 40-year recovery period. Personal property
is depreciated based on its estimated useful life ranging between 5 and 12
years.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with an original
maturity of three months or less at the time of purchase to be cash equivalents.
At December 31, 1997, cash and cash equivalents consisted primarily of shares of
a money market fund.

                      WINROCK-HOUSTON LIMITED PARTNERSHIP
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Deferred Costs
 
     Financing costs and deferred fees are capitalized and amortized using the
straight-line method over the terms of the related agreements. Financing costs
are amortized as interest expense. As of December 31, 1997 and 1996, unamortized
deferred costs of approximately $540,000 and $607,000, respectively, are
included in other assets.
 
  Goodwill
 
     Goodwill is amortized using the straight-line method over 40 years. As of
December 31, 1997 and 1996, unamortized goodwill of approximately $635,000 is
included in other assets.
 
  Leases
 
     The Operating Partnership generally leases apartment units for twelve-month
terms or less. The Partnership recognizes income as earned on its leases.
 
  Security deposits
 
     The Operating Partnership requires security deposits from lessees for the
duration of the lease and such deposits are included in receivables and
deposits. The security deposits are refunded when the tenant vacates, provided
the tenant has not damaged its space and is current on its rental payments.
 
  Advertising
 
     The Operating Partnership expenses the costs of advertising as incurred.
Advertising expense, included in operating expenses, was approximately $114,000
and $89,000, for the years ended December 31, 1997 and 1996, respectively.
 
  Income Taxes
 
     Taxable income or loss of the Partnership is reported in the income tax
returns of its partners. Accordingly, no provision for income taxes is made in
the financial statements of the Partnership.
 
  Allocation of Profits, Losses and Cash Distributions
 
     In accordance with the partnership agreement, cash available for
distribution is distributed 99% to the investor limited partners and 1% to FWC,
the general partner, until the investor limited partners have received a 6%
noncumulative, simple annual rate of return on their invested capital, at which
point the remainder will be distributed 97% to the investor limited partners and
3% to FWC. Distributions of cash other than cash flow shall be distributed in
accordance with the partnership agreement with no less than 1% allocated to the
general partner. Income shall be allocated to the partners in proportion to the
cash available for distribution that is distributable to the partners; losses
shall be allocated 99% to the investor limited partners and 1% to FWC. If there
is no such cash available for distribution, income will be allocated 97% to the
investor limited partner and 3% to the general partner.
 
  Reclassifications
 
     Certain amounts from 1996 have been reclassified to conform to the 1997
presentation.
 
NOTE 3 -- DISTRIBUTIONS
 
     The Partnership distributed approximately $238,000 ($952 per unit) to the
Limited Partners and approximately $2,000 to the general partner during the year
ended December 31, 1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     For the year ended December 31, 1996, the Partnership distributed
approximately $14,248,000 ($56,992 per unit) to the Limited Partners. The
general partner was entitled to $142,500 for the year ended December 31, 1996,
but received only $2,500. The $140,000 underpayment will be paid in future
distributions. The distributions in 1996 were primarily from the net proceeds
received from the mortgage refinancing.
 
NOTE 4 -- TAXABLE INCOME (LOSS)
 
     The following summarizes the differences between the Partnership's taxable
income (loss) for 1997 and 1996, and the Partnership's net income (loss) for

NOTE 5 -- RELATED PARTY TRANSACTIONS
 
     The Partnership has no employees and is dependent on the General Partner
and its affiliates for the management and administration of all partnership
activities. The Partnership paid property management fees based upon 5% of
collected gross rental revenues for property management services. The
partnership agreement provides for reimbursement to the General Partner and its
affiliates for costs incurred in connection with the administration of
Partnership activities. The Partnership pays an annual partnership
administrative and investor service fee of $50,000, which, since 1989, has been
increased annually by 6% to its present level of $84,000. In addition, the
Partnership pays an annual asset management fee equal to 1% of collected gross
rental revenues. The General Partner and its affiliates received reimbursements
and fees as reflected in the following table:

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Winrock-Houston Limited Partnership:
 
     We have audited the accompanying consolidated balance sheet of
Winrock-Houston Limited Partnership (the "Partnership") as of December 31, 1996,
and the related consolidated statements of operations, partners' equity and cash
flows for the year then ended. These financial statements are the responsibility
of the Partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audit. The financial statements of the
Partnership as of December 31, 1995, were audited by other auditors whose report
dated February 9, 1996, expressed an unqualified opinion on those statements.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Winrock-Houston Limited
Partnership as of December 31, 1996, and the results of its operations and its
cash flows for the year then ended in conformity with generally accepted
accounting principles.

                      WINROCK-HOUSTON LIMITED PARTNERSHIP
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995
 
NOTE 1 -- ORGANIZATION
 
     Winrock-Houston Limited Partnership (the "Partnership") was formed on July
21, 1988 under the laws of the State of Delaware for the purpose of acquiring a
general and limited partnership interest in Winrock-Houston Associates Limited
Partnership, a Delaware limited partnership (the "Operating Partnership"). The
Operating Partnership was formed to acquire, renovate and operate four separate,
but nearly contiguous, apartment complexes located in Houston, Texas (the
"Properties"). The Partnership owns a combined 80% general and limited
partnership interest in the Operating Partnership. Winrock-Houston Joint
Venture, a Maryland general partnership, owns a combined 20% general and limited
partnership interest in the Operating Partnership. The general partner of the
Partnership is First Winthrop Corporation ("FWC"). The Partnership will
terminate on December 31, 2037, or earlier upon the occurrence of certain events
specified in the partnership agreement.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The accompanying consolidated financial statements include the accounts of
the Partnership and the Operating Partnership prepared on the accrual basis of
accounting in accordance with generally accepted accounting principles.
Winrock-Houston Joint Venture's ownership interest in the Operating Partnership
has been reflected as a minority interest in the accompanying consolidated
balance sheets and statements of operations. All significant intercompany
accounts and transactions have been eliminated in consolidation.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Real Estate
 
     The Partnership and the Operating Partnership depreciate real property
using the straight-line method over a 40-year recovery period. Personal property
is depreciated using the 150% declining-balance method over a 5- to 12-year
recovery period based on its estimated useful life.
 
     On January 1, 1996, the Partnership adopted Statement of Financial
Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires
impairment losses to be recognized for long-lived assets used in operations when
indicators of impairment are present and the undiscounted cash flows are not
sufficient to recover the asset's carrying amount. The adoption of the SFAS had
no effect on the Partnership's consolidated financial statements.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with an original
maturity of three months or less at the time of purchase to be cash equivalents.
At December 31, 1996, cash and cash equivalents consisted primarily of shares of
a money market mutual fund.
 
  Deferred Costs
 
     Financing costs and deferred fees are capitalized and amortized using the
straight-line method over the terms of the related agreements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Goodwill
 
     Goodwill is amortized using the straight-line method over 40 years.
 
  Income Taxes
 
     No provision for income taxes is reflected in the accompanying consolidated
financial statements. The partners are required to report their allocable share
of the income, gains, losses, deductions and credits of the Partnership on their
individual income tax returns.
 
  Allocation of Profits, Losses and Cash Distributions
 
     In accordance with the partnership agreement, cash available for
distribution is distributed 99% to the investor limited partners and 1% to FWC,
the general partner, until the investor limited partners have received a 6%
noncumulative, simple annual rate of return on their invested capital at which
point the remainder will be distributed 97% to the investor limited partners and
3% to FWC. Distributions of cash other than cash flow shall be distributed in
accordance with the partnership agreement with no less than 1% allocated to the
general partner. Income shall be allocated to the partners in proportion to the
cash available for distribution that is distributable to the partners; losses
shall be allocated 99% to the investor limited partners and 1% to FWC. If there
is no such cash available for distribution, income will be allocated 97% to the
investor limited partner and 3% to the general partner.
 
  Reclassifications
 
     Certain amounts from 1995 have been reclassified to conform to the 1996
presentation.
 
NOTE 3 -- DISTRIBUTIONS
 
     The Partnership distributed $14,247,500 ($56,990 per unit) to the Limited
Partners during the year ended December 31, 1996. The general partner was
entitled to $142,500 for the year ended December 31, 1996 but received only
$2,500. The $140,000 underpayment will be paid in future distributions. The
distributions were primarily from the net proceeds received from the mortgage
refinancing (see Note 6).
 
     For the year ended December 31, 1995, distributions of $625,000 ($2,500 per
unit) and $6,313 were paid to the investor limited and general partners,
respectively.

NOTE 5 -- RELATED PARTY TRANSACTIONS
 
     The Partnership has incurred charges by and commitments to companies
affiliated by common ownership and management with the general partner. Related
party transactions with FWC and its affiliates include the following:
 
     The Partnership pays an affiliate of FWC an annual asset management fee in
an amount equal to 1% of gross operating revenues from the Property for services
rendered with respect to the supervision of the management agent. Management
fees of $75,412 and $72,939 were paid for the years ended December 31, 1996 and
1995, respectively.
 
     Winthrop Management, an affiliate of FWC, is entitled to a property
management fee equal to 5% of gross collections from the properties they manage.
Management fees of $377,058 and $364,696 were paid for the years ended December
31, 1996 and 1995, respectively.
 
     The Partnership pays to the FWC an annual partnership administration and
investor service fee of $50,000, which, since 1989, has been increased annually
by 6%. Fees of $79,693 and $75,182 were paid during the year ended December 31,
1996 and 1995, respectively.
 
     During 1996, an affiliate of the general partner acquired, pursuant to a
tender offer, for a purchase price of $16,500 per unit, approximately 35% of the
total limited partnership units of the Partnership (88 1/2 units).
 
     Included in the accompanying statement of operations for the year ended
December 31, 1995 are legal fees of $450,000, which were incurred in connection
with an attempt by certain parties to remove FWC as the general partner of the
Partnership.
 
     The Partnership paid to an affiliate of FWC reimbursements for
administrative expenses of approximately $11,000 for the year ended December 31,
1996.
 
     In connection with the new mortgage note encumbering the Properties (Note
6), Winthrop Management was paid a refinancing fee of $161,250.
 
NOTE 6 -- MORTGAGE PAYABLE
 
     In January 1996, the Operating Partnership obtained a $21,500,000 mortgage
note, which is collateralized by the Properties. The loan is a 10-year balloon
mortgage with an interest rate of 7.875%. Under the terms of the new loan
agreement, the Operating Partnership is required to make monthly principal and
interest installments of $164,164 through February 1, 2006, based upon a 25 year
amortization period, at which time the remaining principal of approximately
$17,000,000 is due.
 
     In connection with the new financing arrangement the Operating Partnership
closed its master revolving credit line from a prior loan agreement and the
outstanding balance of $2,554,817 was entirely paid off with the proceeds from
the new mortgage loan.
 
     Scheduled principal payments on the mortgage payable subsequent to December
31, 1996 are as follows:

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4664
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4665
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Winthrop Apartment Investors Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   4670
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4671
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,230 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $          per year on the number of
     Tax-Deferral      % Preferred OP Units or distributions of $          per
     year on the number of Tax-Deferral Common OP Units that you would receive
     in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   4673
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4676
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties, to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4677
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4678
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4679
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4680
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. In addition to the general
partner interest, we currently own a 17.40% limited partnership interest in your
partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the
 
                                      S-12
<PAGE>   4681
 
     benefits that your general partner expects to result from the offer. For
     example, a partner of your partnership would have no opportunity for
     liquidity unless he were to sell his units in a private transaction. Any
     such sale would likely be at a very substantial discount from the partner's
     pro rata share of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

     - upon the failure to satisfy any of the conditions to the offer, delay the

     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your properties'
physical condition, locations and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including, those of REITS, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you, from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   4686
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity from your partnership. The property manager received
management fees of $254,000 in 1996, $259,000 in 1997 and $129,295 for the first
six months of 1998. We have no current intention of changing the fee structure
for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated

     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated

     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration, from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4695
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4696
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $          , current annualized distributions with
respect to the Common OP Units are $2.25, and the 1997 distributions with
respect to your units were $3,250. This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently own a 17.40% limited partnership interest in your partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   4698
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties may improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   4699
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4701
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4702
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   4703
 
 Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation
 to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.

<PAGE>   4704
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   4706
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

        (f) a tender or exchange offer for any units shall have been commenced

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If AIMCO Operating
Partnership acquires units in the offer, AIMCO will increase its ability to
influence voting decisions with respect to your partnership. Furthermore, in the
event that the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, removal of the general partner of your partnership
(which general partner is controlled by AIMCO) without AIMCO's consent may
become more difficult or impossible. AIMCO also owns the company that manages
your partnership's property. In the event that the AIMCO Operating Partnership
acquires a substantial number of units pursuant to the offer, removal of the
property manager may become more difficult or impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   4709
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any

     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   4712
 
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   4714
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4719
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4720
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your properties'
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4722
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   4723
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $          , current annualized distributions with respect to
     the Common OP Units are $2.25, and the 1997 distributions with respect to
     your units were $3,250 per unit. This is equivalent to distributions of
     $          per year on the number of Tax-Deferral      % Preferred OP
     Units, or distributions of $          per year on the number of
     Tax-Deferral Common OP Units, that you would receive in an exchange for
     each of your partnership's units. Therefore, distributions with respect to
     the Preferred OP Units and Common OP Units that we are offering are
     expected to be        , immediately following our offer, than the
     distributions with respect to your units. See "Comparison of Ownership of
     Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   4724
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Price............................................    $

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   4728
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity and fees for additional services from your
partnership. The property manager received management fees of $254,000 in 1996,
$259,000 in 1997 and $129,295 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

Insignia in October, 1998. There are currently a total of 284 limited partners
of your partnership and a total of 251 units of your partnership outstanding.
Your partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the small number of apartment
properties described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on September 4, 1991 for the purpose of owning
and operating a small number of apartment properties located in Austin, Texas,
Irving, Texas, Atlanta, Georgia, and Alpharetta, Georgia, known as "Chesapeake
(Lost Mill) Apartments," "Covington Creek Apartments," "Northside Circle
Apartments" and "Webb Bridge Crossing Apartments," respectively. There are 124
apartment units in "Chesapeake (Lost Mill) Apartments." The total rentable
square footage is 79,456 square feet and the average annual rent per apartment
unit is $5,931. "Covington Creek Apartments" has 248 apartment units. The total
rentable square footage is 193,362 square feet. The average annual rent per
apartment unit is $6,492. In "Northside Circle Apartments," there are 219
apartment units. The total rentable square footage is 160,180 square feet and
the average annual rent per apartment unit is $6,477. There are 164 apartment

170,164 square feet and the average annual rent per apartment unit is $7,138.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $254,000, $259,000 and $129,295, respectively.
 
     The manager of your partnership's property is an affiliate of the general
partner of your partnership and of AIMCO.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2041
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.

     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.
 
CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had a current mortgage
notes outstanding on "Chesapeake (Lost Mill) Apartments" of $2,035,802,
"Northside Circle Apartments" of $5,011,205 and "Webb Bridge Crossing
Apartments" of $4,384,804 payable to Nomura Asset Capital Corp., which bear
interest at a rate of 7.27%. Such mortgage notes are due February 2026. There is

$4,288,204, as of June 30, 1998. The note bears interest at 7.27% and is due
March 2026. Your partnership's agreement of limited partnership also allows the
general partner of your partnership to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

The decrease in net income of $ 70,000, or 14.37% was primarily the result of an
increase in operating expenses. These factors are discussed in more detail in
the following paragraphs.

     Rental and other property revenues from the partnership's property totaled
$5,273,000 for the year ended December 31, 1997, compared to $5,239,000 for the
year ended December 31, 1996, an increase of $34,000, or 0.65%.

                                      S-75
<PAGE>   4744
 
     1996, an increase of $73,000 or 3.34%. Management expenses totaled $259,000
for the year ended December 31, 1997, compared to $254,000 for the year ended
December 31, 1996, an increase of $5,000, or 1.97%.
 
     General and Administrative Expenses

costs, totaled $1,280,000 for the year ended December 31, 1997, compared to
$1,267,000 for the year ended December 31, 1996, an increase of $13,000, or
1.03%.
 
     Comparison of the Year Ended December 31, 1996 to the Year Ended December
31, 1995
 
     Net Income
 
     Your partnership recognized net income of $487,000 for the year ended
December 31, 1996, compared to $1,888,000 for the year ended December 31, 1995.
The decrease in net income of $1,401,000, or 74.21% was primarily the result of
an increase in interest expense.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$5,239,000 for the year ended December 31, 1996, compared to $5,148,000 for the
year ended December 31, 1995, an increase of $91,000, or 1.77%.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $2,187,000 for
the year ended December 31, 1996, compared to $1,770,000 for the year ended
December 31, 1995, an increase of $417,000 or 23.56%. The increase in operating
expenses is due mainly to an increase in professional and amortization expenses
coupled with a reclassification of certain expenses to operating expense that
were included in general and administrative expenses at December 31, 1995.
Amortization expenses increased due to additional amortization of the deferred
legal and mortgage costs associated with the Partnership's refinancing.
Management expenses totaled $254,000 for the year ended December 31, 1996,
compared to $243,000 for the year ended December 31, 1995, an increase of
$11,000, or 4.53%.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $93,000 for the year ended
December 31, 1996 compared to $306,000 for the year ended December 31, 1995, a
decrease of $213,000 or 69.61%. The decrease is primarily due to the
reclassification of certain general and administrative expenses for 1995 to
operating expenses in 1996.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $1,267,000 for the year ended December 31, 1996, compared to $0
for the year ended December 31, 1995, an increase of $1,267,000. The increase is
due to the partnership securing $16 million in new debt during 1996.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $1,662,921 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable for damages or
otherwise to your partnership or any limited partner for any acts performed or
any failure to act by any of them if they determined, in good faith, that such
acts or failure to act was in the best interests of your partnership, and such
course of conduct did not constitute negligence or misconduct on the part of
such person. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partner and their affiliates are entitled to indemnification by
your partnership against any loss, damage, liability, cost or expense sustained
by it or them if such person determined, in good faith that the course of
conduct which caused the loss or liability was in the best interests of your
partnership and such person was acting on behalf or performing services for your
partnership, provided that such loss, damage, liability, cost or expense was not
the result of negligence or misconduct by such person. Any such indemnity
provided shall be paid, from and only to the extent of, partnership assets.
Notwithstanding any other provision to the contrary, the general partner, its
affiliates and any person acting as broker-dealer will be liable and will not be
entitled to indemnity for any loss, damage or cost resulting from violations of
Federal or state securities laws in connection with the units unless there has
been a successful adjudication of the merits of each count involving such
securities law violations, such claims have been dismissed with prejudice on the
merits by a court of competent jurisdiction or a court of competent jurisdiction
approves a settlement of such claims. In any claim for indemnification for
Federal or state securities law violations, the party seeking indemnification
must place before the court the position of the SEC and any other applicable
regulatory agency with respect to the issue of indemnification for securities
law violations. The advancement of partnership funds to the general partner or
its affiliates for legal expenses and other cost incurred as a result of any
legal action is allowed if: the legal action related to your partnership or to
acts or omissions with respect to the performance of duties or services on
behalf of your partnership, the legal action is initiated by a third party who
is not a limited partner or the legal action is initiated by a limited partner
and a court of competent jurisdiction specifically approves such advancement and
the general partner or its affiliates undertake to repay the advanced funds in
cases in which such party is not entitled to indemnification. As part of its
assumption of liabilities in the consolidation, AIMCO will indemnify the general
partner of your partnership and their affiliates for periods prior to and
following the consolidation to the extent of the indemnity under the terms of
your partnership's agreement of limited partnership and applicable law.
 
     No partnership funds will be used to purchase any insurance the insures any
party against any liability for which indemnification is not available pursuant
to your partnership's agreement of limited partnership.

the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), there have
been no units transferred in sale transactions (excluding transactions believed
to be between related parties, family members or the same beneficial owner):
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partners -- by your partnership
including reimbursement for expenses) management fees and distributions in its
capacity as general partner interest of partnership as described in the
following table:

partnership. Your partnership has historically paid the property management fees
as described in the following table:

general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Winthrop Apartment
Investors Limited Partnership as of June 30, 1998 and for the six months ended
June 30, 1998 have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for a fair presentation have
been included and all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners of
Winthrop Apartment Investors Limited Partnership
Greenville, South Carolina
 
     We have audited the accompanying balance sheets of Winthrop Apartment
Investors Limited Partnership (a Maryland limited partnership) as of December
31, 1997 and 1996, and the related statements of operations, partners' capital
and cash flows for the years then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures of the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Winthrop Apartment Investors
Limited Partnership, a Maryland limited partnership, as of December 31, 1997 and
1996, and the results of its operations and its cash flows for the years then
ended in conformity with generally accepted accounting principles.

                     YEARS ENDED DECEMBER 31, 1997 AND 1996
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Winthrop Apartment Investors Limited Partnership (the "Partnership") was
organized on September 5, 1991 under the laws of the State of Maryland for the
purpose of acquiring, renovating, operating and managing residential apartment
complexes. The Partnership's properties are located in Austin, Texas (Chesapeake
Apartments); Irving, Texas (Covington Creek Apartments); Fulton County, Georgia
(Webb Bridge Crossing Apartments); and Atlanta, Georgia (Northside Circle
Apartments).
 
     The general partner of the Partnership is WAI Associates Limited
Partnership, a Texas limited Partnership ("WAI" or the "General Partner"), whose
sole general partner is WAI Properties, Inc., a Texas corporation and a wholly
owned subsidiary of First Winthrop Corporation ("First Winthrop"). The sole
limited partner of WAI is Winthrop Financial Associates ("WFA"). First Winthrop
is a wholly owned subsidiary of WFA.
 
     On October 28, 1997, Insignia Financial Group, Inc. ("Insignia") acquired
100% of the Class B stock of First Winthrop. Pursuant to this transaction,
Insignia has the right to appoint the members of a Residential Committee. The
Residential Committee effectively controls the activities of the Partnership.
 
     The Partnership was capitalized with $24,700,000 of contributions
representing 250 investor limited partnership units. The offering closed on
December 31, 1992. The general partner and affiliates contributed $1,000. The
Partnership will terminate December 31, 2041 unless dissolved earlier, pursuant
to the provisions of the Partnership Agreement ("Agreement").
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Allocation of Income, Losses and Distributions
 
     In accordance with the partnership agreement, distributions of cash flow
are allocated 99% to the limited partners and 1% to the general partner, until
the limited partners have received a 6% noncumulative, noncompounded annual rate
of return on their net invested capital, at which point the remainder is
distributed 90% to the limited partners and 10% to the general partner.
Distributions of cash other than cash flow are distributed in accordance with
the partnership agreement, with no less than 1% allocated to the general
partner. Income is allocated to the partners in proportion to the cash available
for distribution to the partners; losses are allocated 90% to the limited
partners and 10% to the general partner. If there is no cash available for
distribution, income is allocated 90% to the limited partners and 10% to the
general partner.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents includes cash on hand and in banks, certificates
of deposit, and money market funds with original maturities less than 90 days.
At certain times, the amount of cash deposited at a bank may exceed the limit on
insured deposits.
 
  Security deposits
 
     The Partnership requires security deposits from lessees for the duration of
the lease and such deposits are included in other assets. The security deposits
are refunded when the tenant vacates, provided the tenant has not damaged its
space and is current on its rental payments.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Investment Properties
 
     Investment properties are stated at cost. The Partnership records
impairment losses on long-lived assets used in operations when events and
circumstances indicate that the assets might be impaired and the undiscounted
cash flows estimated to be generated by those assets are less than the carrying
amounts of those assets.
 
  Deferred Costs
 
     Organization costs are amortized on the straight-line basis over five
years. Acquisition fees are amortized on the straight-line basis over 27.5 and
40 years. Deferred financing costs are amortized as interest expense on the
straight-line basis over the life of the loan.
 
  Depreciation
 
     The Partnership provides for depreciation of buildings and improvements on
the straight-line basis over their estimated useful lives of 40 years for
buildings and improvements and 3 to 15 years for personal property.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less. The Partnership recognizes income as earned on its leases.
 
  Advertising
 
     The Partnership expenses the costs of advertising as incurred. Advertising
expense, included in operating expenses, was approximately $75,000 and $64,000,
for the years ended December 31, 1997 and 1996, respectively.
 
  Income Taxes
 
     Taxable income or loss of the Partnership is reported in the income tax
returns of its partners. Accordingly, no provision for income taxes is made in
the financial statements of the Partnership.
 
  Reclassification
 
     Certain amounts from 1996 have been reclassified to conform to the 1997
presentation.
 
2. RELATED PARTY TRANSACTIONS
 
     The Partnership has no employees and is dependent on the General Partner
and its affiliates for the management and administration of all partnership
activities. The Partnership paid property management fees based upon collected
gross rental revenues for property management services as noted below for the
years ended December 31, 1997 and 1996. Such fees are included in operating
expenses on the statements of operations and are reflected in the following
table. The Partnership Agreement provides for reimbursement to the General
Partner and its affiliates for costs incurred in connection with the
administration of Partnership activities. The General Partner and its affiliates
received reimbursements and fees as reflected in the following table:

4. MORTGAGE NOTE PAYABLE
 
     On January 5, 1996, the Partnership obtained a mortgage loan in the amount
of $16,000,000 secured by all of the properties. The loan amount was allocated
$2,080,000, $4,320,000, $5,120,000 and $4,480,000 to Chesapeake Apartments,
Covington Creek Apartments, Northside Circle Apartments and Webb Crossing
Apartments, respectively. The mortgage loan bears interest at an initial rate of
7.27% (until the "Optional Prepayment Date", as defined), requires monthly
principal and interest payments of approximately $109,000 and matures in
February 2026. The Partnership has the option to prepay the mortgage loan
without penalty on, or three months before, February 1, 2003 (the "Optional
Prepayment Date"). If the Partnership does not elect to prepay the loan, the
interest rate will be adjusted to the greater of 12.27% or a "Treasury Rate" (as
defined) plus 7.75 percentage points. The Partnership was required to fund
approximately $278,000 in reserves at closing to complete certain required
capital improvements to the properties, and establish tax and insurance escrows.
The Partnership is also required to fund an ongoing replacement reserve. In
connection with the closing, Two Winthrop was replaced as the General Partner of
the Partnership with WAI Associates Limited Partnership. The lender required the
transfer of the general partnership interest as a condition to making the loan
to assure that the Partnership and its general partner are single purpose
entities, formed solely for the purpose of owning and operating the properties.
 
     As of December 31, 1997 principal payments are required as follows:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Partners of
Winthrop Apartment Investors Limited Partnership:
 
     We have audited the accompanying balance sheets of Winthrop Apartment
Investors Limited Partnership (a Maryland limited partnership) as of December
31, 1995 and the related statements of operations, changes in partners' capital
and cash flows for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Winthrop Apartment Investors
Limited Partnership as of December 31, 1995, the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1996 AND 1995
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Winthrop Apartment Investors Limited Partnership (the "Partnership") was
organized on September 5, 1991 under the laws of the State of Maryland for the
purpose of acquiring, renovating, operating and managing residential apartment
complexes. The Partnership's properties are located in Austin, Texas (Chesapeake
Apartments); Irving, Texas (Covington Creek Apartments); Fulton County, Georgia
(Webb Bridge Crossing Apartments); and Atlanta, Georgia (Northside Circle
Apartments).
 
     The general partner of the Partnership is WAI Associates Limited
Partnership, a Texas limited Partnership ("WAI" or the "General Partner"), whose
sole general partner is WAI Properties, Inc., a Texas corporation and a wholly
owned subsidiary of First Winthrop Corporation ("First Winthrop"). The sole
limited partner of WAI is Winthrop Financial Associates ("WFA"). First Winthrop
is a wholly owned subsidiary of WFA. The general partner of the Partnership was,
until January 1996, Two Winthrop Limited Partnership ("Two Winthrop") an
affiliate of WAI.
 
     The Partnership was capitalized with $24,700,000 of contributions
representing 50 investor limited partnership units. The offering closed on
December 31, 1992. The general partner and affiliates contributed $1,000.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Accounting Change
 
     On January 1, 1996, the Partnership adopted Statement of Financial
Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of", which requires
impairment losses to be recognized for long-lived assets used in operations when
indicators of impairment are present and the undiscounted cash flows are not
sufficient to recover the asset's carrying amount. The impairment loss is
measured by comparing the fair value of the asset to its carrying amount. The
adoption of the SFAS has no effect on the Partnership's financial statements.
 
  Income Taxes
 
     Taxable income or loss of the Partnership is reported in the income tax
returns of its partners. Accordingly, no provision for income taxes is made in
the financial statements of the Partnership.
 
  Deferred Costs
 
     Organization costs are amortized on the straight-line basis over five
years. Acquisition fees are amortized on the straight-line basis over 27.5 and
40 years. Deferred financing costs are amortized on the straight-line basis over
the life of the loan. Financing fees paid to the lender are amortized as
interest expense over the life of the loan.
 
  Depreciation
 
     The Partnership provides for depreciation of buildings and improvements on
the straight-line basis over their estimated useful lives of 40 years for
buildings and improvements and 3 to 15 years for personal property.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Concentration of Credit Risk
 
     Principally all of the Partnership's cash and cash equivalents consist of a
mutual fund that invests in U.S. treasury bills and repurchase agreements with
original maturity dates of three months or less.
 
  Reclassification
 
     Certain amounts from 1995 have been reclassified to conform to the 1996
presentation.
 
2. RELATED PARTY TRANSACTIONS
 
     Winthrop Management, an affiliate of the managing general partner, is paid
an annual property management fee equal to 5% of gross receipts from all
Partnership properties managed by Winthrop Management. Such fees aggregated
$254,000 and $243,000 in 1996 and 1995, respectively. Winthrop Management was
also paid an $80,000 fee relating to the mortgage financing (see Note 4).
 
3. DEFERRED COSTS

</TABLE>
 
4. MORTGAGE PAYABLE
 
     On January 5, 1996, the Partnership obtained a mortgage loan in the amount
of $16,000,000 secured by all of the properties. The loan amount was allocated
$2,080,000, $4,320,000, $5,120,000 and $4,480,000 to Chesapeake Apartments,
Covington Creek Apartments, Northside Circle Apartments and Webb Crossing
Apartments, respectively. The mortgage loan bears interest at an initial rate of
7.27% (until the "Optional Prepayment Date", as defined), requires monthly
principal and interest payments of approximately $109,000 and matures in
February 2026. The Partnership has the option to prepay the mortgage loan
without penalty on, or three months before, February 1, 2003 (the "Optional
Prepayment Date"). If the Partnership does not elect to prepay the loan, the
interest rate will be adjusted to the greater of 12.27% or a "Treasury Rate" (as
defined) plus 7.75 percentage points. The Partnership was required to fund
approximately $278,000 in reserves at closing to complete certain required
capital improvements to the properties, and establish tax and insurance escrows.
The Partnership is also required to fund an ongoing replacement reserve. In
connection with the closing, Two Winthrop was replaced as the General Partner of
the Partnership with WAI Associates Limited Partnership. The lender required the
transfer of the general partnership interest as a condition to making the loan
to assure that the Partnership and its general partner are single purpose
entities, formed solely for the purpose of owning and operating the properties.

</TABLE>
 
5. ALLOCATION OF INCOME, LOSSES AND DISTRIBUTIONS
 
     In accordance with the partnership agreement, cash flow distributions shall
be allocated 99% to the limited partners and 1% to the general partner, until
the limited partners have received a 6% noncumulative, noncompounded annual rate
of return on their net invested capital, at which point the remainder shall be
distributed 90% to the limited partners and 10% to the general partner.
Distributions of cash other than cash flow shall be distributed in accordance
with the partnership agreement with no less than 1% allocated to the general
partner. Income shall be allocated to the partners in proportion to the cash
available for distribution to the partners; losses shall be allocated 90% to the
limited partners and 10% to the general partner. If there is no such cash
available for distribution, income will be allocated 90% to the limited partners
and 10% to the general partner.
 
6. DISTRIBUTIONS
 
     The Partnership distributed $17,410,000 ($69,640 per unit) to the Limited
Partners during the year ended December 31, 1996. The General Partner was
entitled to $308,000 for the year ended December 31, 1996. The General Partner
was underpaid $97,000 of the 1996 distributions which will be adjusted for in
1997. The distributions included approximately $14,923,000 of proceeds from a
January 1996 mortgage financing (see Note 4).
 
     For the year ended December 31, 1995, distributions of $2,175,000 ($8,700
per unit) and $90,000 were paid to the limited and General Partners,
respectively.
 
7. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of cash and cash equivalents of $1,220,000 approximates
fair value due to the short term nature of such instruments. The carrying amount
of the Partnership's mortgage note of $15,885,000 approximates its fair value
based on the recent financing of such note.
 
8. TAXABLE INCOME
 
     The Partnership's taxable income for 1996 and 1995 differs from that for
financial reporting purposes as follows:

transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of

current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4775
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4776
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Winthrop Texas Investors Limited Partnership. For each unit that you
     tender, you may choose to receive                of our Tax-Deferral      %
     Partnership Preferred Units (also referred to as "Preferred OP Units"),
                    of our Tax-Deferral Partnership Common Units (also referred
     to as "Common OP Units"), or $          in cash (subject, in each case to
     adjustment for any distributions paid to you during the offer period). If
     you like, you can choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.

<PAGE>   4781
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Partnership Preferred Units before any distributions are paid to holders
       of Tax-Deferral Common OP Units. However, one class of outstanding
       Partnership Preferred Units has prior distribution rights and the
       Tax-Deferral   % Preferred OP Units rank equal to six other outstanding
       classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4782
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $1,000 per unit for the year ended
     December 31, 1997. We will pay fixed quarterly distributions of
     $               per unit on the Tax-Deferral   % Preferred OP Units before
     any distributions are paid to holders of Tax-Deferral Common OP Units. We
     pay quarterly distributions on the Tax-Deferral Common OP Units based on
     our funds from operations for that quarter. For the six months ended June
     30, 1998, we paid distributions of $1.125 on each of the Tax-Deferral
     Common OP Units (equivalent to $2.25 on an annual basis). This is
     equivalent to distributions of $          per year on the number of
     Tax-Deferral      % Preferred OP Units or distributions of $          per
     year on the number of Tax-Deferral Common OP Units that you would receive
     in an exchange for each of your partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a small number of apartment
     properties to holding an interest in an operating business that owns and
     manages a large portfolio of properties, with risks that do not exist for
     your partnership. You should review the risk factors in this Prospectus
     Supplement and in the accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
                                       S-4
<PAGE>   4784
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4787
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a small
number of apartment properties to an interest in a partnership that invests in
and manages a large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4788
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4789
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   4790
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   4791
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your
 
                                      S-12
<PAGE>   4792
 
     partnership would have no opportunity for liquidity unless he were to sell
     his units in a private transaction. Any such sale would likely be at a very
     substantial discount from the partner's pro rata share of the fair market
     value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral   % Preferred OP Units
       rank equal to six other outstanding classes of Partnership Preferred
       Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
                                      S-14
<PAGE>   4794
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN THIS

YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the

entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   4797
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, unlike the general partner of the AIMCO Operating Partnership,
the general partner of your partnership is entitled to compensation services
provided in its capacity as general partner.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $25,000
beginning in 1992 and increasing annually at a rate of 6% beginning in 1992 from
your partnership and may receive reimbursement for expenses generated in its
capacity as general partner. The property manager received management fees of
$118,389 in 1996, $137,696 in 1997 and $67,761 for the first six months of 1998.
We have no current intention of changing the fee structure for your property
manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Winthrop Texas Investors Limited
Partnership is a Maryland limited partnership which was formed on September 3,
1991 for the purpose of owning and operating a small number of apartment
properties located in Dallas, Texas and Ft. Worth, Texas, known as "Enfield
Apartments" and "Salem Park Apartments," respectively. In 1991, it completed a
private placement of units that raised net proceeds of approximately
$12,800,000. Enfield Apartments consists of 286 apartment units and Salem Park

     Property Management. Since November 1997, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2041, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
current mortgage notes outstanding of $4,820,785 and of $3,122,921, both payable
to Metropolitan Life, which bear interest at a rate of 7.61%. Both mortgage
debts are due in December 2002. Your partnership's agreement of limited
partnership also allows your general partner to lend funds to your partnership.
Currently, the general partner of your partnership has no loan outstanding to
your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's property, our
offer consideration could be less than the net proceeds that you would realize
upon a future liquidation of your partnership. Accordingly, although there can
be no assurance, you might receive more consideration if you do not tender your
units and, instead, continue to hold your units and ultimately receive proceeds
from a liquidation of your partnership. However, you may prefer to receive our
offer consideration now rather than wait for uncertain future net liquidation
proceeds. Furthermore, your general partner has no present intention to
liquidate your partnership, and your partnership's agreement of limited
partnership does not require a sale of your partnership's property by any
particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4806
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a small number of apartment
properties. In contrast, the AIMCO Operating Partnership is in the business of
acquiring, marketing, managing and operating a large portfolio of apartment
properties. While diversification of assets may reduce certain risks of
investment attributable to a single property or entity, there can be no
assurance as to the value or performance of our securities or our portfolio of
properties as compared to the value of your units or your partnership. Proceeds
of future asset sales or refinancings by the AIMCO Operating Partnership
generally will be reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4807
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $     , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units for the year ended December 30, 1997 were $1,000 per unit. This is
equivalent to distributions of $          per year on the number of Tax-Deferral
     % Preferred OP Units, or distributions of $          per year on the number
of Tax-Deferral Common OP Units, that you would receive in an exchange for each
of your partnership's units. Therefore, distributions with respect to the
Preferred OP Units and Common OP Units that we are offering are expected to be
       , immediately following our offer, than the distributions with respect to
your units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service ("Moody's") revised its outlook for the ratings
of AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of the more difficult general capital
market conditions. Moody's noted that AIMCO's access to the public markets may
prove challenging in light of the volatility in both the equity and capital
markets for REITs. Moody's assigned a "ba3" rating to the Class I Preferred
Stock proposed to be issued by AIMCO, and confirmed its previous ratings related
to AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   4809
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
                                      S-30
<PAGE>   4810
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   4812
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4813
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
                                      S-34
<PAGE>   4814
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
                                      S-35
<PAGE>   4815
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.
 
PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
                                      S-36
<PAGE>   4816
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     time of the commencement of the offer, in the sole judgment of the AIMCO

its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or

circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits that would be material
to the business of your partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of units by the AIMCO
Operating Partnership pursuant to the offer as contemplated herein. While there
is no present intent to delay the purchase of units tendered pursuant to the
offer pending receipt of any such additional approval or the taking
 
                                      S-40
<PAGE>   4820
 
     of any such action, there can be no assurance that any such additional
approval or action, if needed, would be obtained without substantial conditions
or that adverse consequences might not result to your partnership's business, or
that certain parts of your partnership's business might not have to be disposed
of or other substantial conditions complied with in order to obtain such
approval or action, any of which could cause the AIMCO Operating Partnership to
elect to terminate the offer without purchasing units hereunder. The AIMCO
Operating Partnership's obligation to purchase and pay for units is subject to
certain conditions, including conditions related to the legal matters discussed
in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.
 
                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
                                      S-41
<PAGE>   4821
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any
 
                                      S-42
<PAGE>   4822
 
     Parity Units shall be declared ratably in proportion to the respective
amounts of distributions accumulated, accrued and unpaid on the Preferred OP
Units and accumulated, accrued and unpaid on such Parity Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred OP Units
equal to the full amount of accumulated, accrued and unpaid distributions have
been or contemporaneously are declared and paid, or declared and a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for such payment, for all past distribution periods, no distributions shall be
declared or paid or set apart for payment by the AIMCO Operating Partnership
with respect to any Parity Units. Unless full cumulative distributions
(including all accumulated, accrued and unpaid distributions) on the Preferred
OP Units have been declared and paid, or declared and set apart for payment, for
all past distribution periods, no distributions (other than distributions or
distributions paid in Junior Units or options, warrants or rights to subscribe
for or purchase Junior Units) may be declared or paid or set apart for payment
by the AIMCO Operating Partnership and no other distribution of cash or other
property may be declared or made, directly or indirectly, by the AIMCO Operating
Partnership with respect to any Junior Units, nor shall any Junior Units be
redeemed, purchased or otherwise acquired (except for a redemption, purchase or
other acquisition of Common OP Units made for purposes of an employee incentive
or benefit plan of AIMCO, the AIMCO Operating Partnership or any subsidiary) for
any consideration (or any monies be paid to or made available for a sinking fund
for the redemption of any such Junior Units), directly or indirectly, by the
AIMCO Operating Partnership (except by conversion into or exchange for Junior
Units, or options, warrants or rights to subscribe for or purchase Junior
Units), nor shall any other cash or other property be paid or distributed to or
for the benefit of holders of Junior Units. Notwithstanding the foregoing
provisions of this paragraph, the AIMCO Operating Partnership shall not be
prohibited from (i) declaring or paying or setting apart for payment any
distribution on any Parity Units or (ii) redeeming, purchasing or otherwise
acquiring any Parity Units, in each case, if such declaration, payment,
redemption, purchase or other acquisition is necessary to maintain AIMCO's
qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations
 
                                      S-43
<PAGE>   4823
 
     shall have been made in full to the holders of Preferred OP Units and any
Parity Units to enable them to receive their Liquidation Preference, any Junior
Units shall be entitled to receive any and all assets remaining to be paid or
distributed, and the holders of the Preferred OP Units and any Parity Units
shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.
 
                                      S-44
<PAGE>   4824
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   4825
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4830
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4831
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4833
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   4834
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     , current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the year ended December 30, 1997 were $1,000. This is equivalent to
     distributions of $          per year on the number of Tax-Deferral      %
     Preferred OP Units, or distributions of $          per year on the number
     of Tax-Deferral Common OP Units, that you would receive in exchange for
     each of your partnership's units. Therefore, distributions with respect to
     the Preferred OP Units and Common OP Units that we are offering are
     expected to be        , immediately following our offer, than the
     distributions with respect to your units. See "Comparison of Ownership of
     Your Units and AIMCO OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   4835
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar

any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets would be disposed of in an
orderly manner and not sold in forced or distressed sales where sellers might be
expected to dispose of their interests at substantial discounts to their actual
fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.

     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF MATERIALS CONSIDERED
 
     In the course of Stanger's analysis to render its opinion, Stanger: (i)
reviewed a draft of the Prospectus Supplement related to the offer in
substantially the form which will be distributed; (ii) reviewed your
partnership's operating statements ending June 30, 1998, which reports your
partnership's management has indicated to be the most current available
financial statements; (iii) reviewed descriptive information concerning your
partnership's property provided by management, including location, number of
units and unit mix, age, and amenities; (iv) reviewed summary historical
operating statements for your partnership's property for 1996 and 1997 and

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   4839
among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership property. Additionally, we desire
to purchase units at a low price and you desire to sell units at a high price.
The general partner of your partnership makes no recommendation as to whether
you should tender or refrain from tendering your units. Such conflicts of
interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives $25,000
beginning in 1992 and increasing annually at a rate of 6% beginning in 1992 for
services as general partner of your partnership and may receive reimbursement
for expenses generated in its capacity as such. The property manager received
management fees of 118,389 in 1996, 137,696 in 1997 and 67,761 for the first six
months of 1998. The AIMCO Operating Partnership has no current intention of
changing the fee structure for the manager of your partnership property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Winthrop Texas Investors Limited Partnership is a Maryland limited
partnership which raised net proceeds of approximately $12,800,000 in 1991
through a private offering. The promoter for the private offering of your
partnership was Winthrop Securities Co., Inc. Insignia acquired your partnership
in November 1997. AIMCO acquired Insignia in October, 1998. There are currently
a total of 127 limited partners of your partnership and a total of 128 units of
your partnership outstanding. Your partnership is in the business of owning and
managing residential housing. Currently, your partnership owns and manages the
small number of apartment properties described below. Your partnership has no
employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on September 3, 1991 for the purpose of owning
and operating a small number of apartment properties located in Dallas, Texas
and Ft. Worth, Texas, known as "Enfield Apartments" and "Salem Park Apartments,"
respectively. There are 286 apartment units in Enfield Apartments. The total
rentable square footage is 208,383 square feet and the average annual rent per
apartment unit is $5,366. Salem Park Apartments has 168 apartment units. The
total rentable square footage is 156,876 square feet. The average annual rent
per apartment unit is 6,233.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since November 1997, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $118,389, $137,696 and $67,761, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2041
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. As of June 30, 1998, your partnership had current mortgage notes
outstanding on Enfield Apartments of $4,820,785 and Salem Park Apartments of
$3,122,921 payable to Metropolitan Life, which bear interest at a rate of 7.61%.
Such mortgage notes are due December 2002. Your partnership's agreement of
limited partnership also allows the general partner of your partnership to lend
funds to your partnership. Currently, the general partner of your partnership
has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $1,662,921 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership and
its affiliates are not liable, responsible or accountable for damages or
otherwise to your partnership or any limited partner for any acts performed or
any failure to act by any of them if they determined, in good faith, that such
acts or failure to act was in the best interests of your partnership, and such
course of conduct did not constitute negligence or misconduct on the part of
such person. As a result, unitholders might have a more limited right of action
in certain circumstances than they would have in the absence of such a provision
in your partnership's agreement of limited partnership. The general partner of
your partnership is owned by AIMCO. See "Conflicts of Interest".
 
     The general partner and its affiliates are entitled to indemnification by
your partnership against any loss, damage, liability, cost or expense sustained
by it or them in connection with your partnership, provided that such loss,
damage, liability, cost or expense was not the result of negligence or
misconduct by such person. Any such indemnity provided shall be paid, from and
only to the extent of, partnership assets. Notwithstanding any other provision
to the contrary, the general partner and its affiliates will be liable and will
not be entitled to indemnity for any loss, damage or cost resulting from
violations of Federal or state securities laws in connection with the units
unless there has been a successful adjudication of the merits of each count
involving such securities law violations, such claims have been dismissed with
prejudice on the merits by a court of competent jurisdiction or a court of
competent jurisdiction approves a settlement of such claims. In any claim for
indemnification for Federal or state securities law violations, the party
seeking indemnification must place before the court the position of the SEC and
any other applicable regulatory agency with respect to the issue of
indemnification for securities law violations.
 
     No partnership funds will be used to purchase any insurance the insures any
party against any liability for which indemnification is not available pursuant
to your partnership's agreement of limited partnership. As part of its
assumption of liabilities in the consolidation, AIMCO will indemnify the general
partner of your partnership and their affiliates for periods prior to and
following the consolidation to the extent of the indemnity under the terms of
your partnership's agreement of limited partnership and applicable law.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been
 
                                      S-76
<PAGE>   4856
 
     limited and sporadic. The general partner of your partnership monitors
transfers of the units (a) because the admission of the transferee as a
substitute limited partner in your partnership require the consent of the
general partner of your partnership under your partnership's agreement of
limited partnership, and (b) in order to track compliance with safe harbor
provisions to avoid treatment as a "publicly traded partnership" for tax
purposes. However, the general partner of your partnership does not monitor or
regularly receive or maintain information regarding the prices at which
secondary sale transactions in the units have been effectuated. The general
partner of your partnership estimates, based solely on the transfer records of
your partnership (or your partnership's transfer agent), that there have been no
units transferred in sale transactions (excluding transactions believed to be
between related parties, family members or the same beneficial owner).
 
BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP
 
     Neither AIMCO, nor, to the best of its knowledge, any of its affiliates,
(i) beneficially own or have a right to acquire any units, (ii) have effected
any transaction in the units, or (iii) have any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of your partnership, including, but not limited to, contracts,
arrangements, understandings or relationships concerning transfer or voting
thereof, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
 
COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES
 
     The general partner of your partnership received total compensation (which
includes all monies paid to the general partner by your partnership including
reimbursement for expenses) in its capacity as general partner of your
partnership as described in the following table:

general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                     FOR THE SIX MONTHS ENDED JUNE 30, 1998
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Winthrop Texas Investors
Limited Partnership as of June 30, 1998 and for the six months then ended have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that the accounting measurements at interim dates
inherently involve greater reliance on estimates than at year-end. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire year.

                          INDEPENDENT AUDITORS' REPORT
 
To the Partners
Winthrop Texas Investors Limited Partnership
 
     We have audited the accompanying balance sheets of Winthrop Texas Investors
Limited Partnership as of December 31, 1997 and 1996, and the related statements
of income, partners' equity (deficit) and cash flows for the years then ended.
These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Winthrop Texas Investors
Limited Partnership as of December 31, 1997 and 1996, and the results of its
operations, the changes in partners' equity (deficit) and cash flows for the
years then ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Winthrop Texas Investors Limited Partnership (the "partnership"), a limited
partnership, was formed September 20, 1993 under the laws of the State of
Maryland to acquire, renovate, and operate two residential apartment complexes
(the "properties") consisting of a total of 454 market-rate rental apartment
units, located in Dallas and Fort Worth, Texas. The properties are situated on a
total of approximately 12.4 acres of land known as the Enfield Apartments (in
Dallas) and the Salem Park Apartments (in Fort Worth). Termination of the
partnership will occur on December 31, 2041 or earlier upon the occurrence of
certain events specified in the partnership agreement.
 
     The general partner is Two Winthrop Limited Partnership. The initial
limited partner was WFC Realty Co., Inc., which withdrew from the partnership
upon the first admission of investors. The partnership sold 128 limited
partnership units at $100,000 per unit.
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with generally accepted accounting principles.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Investment in Real Estate
 
     Rental property is carried at cost. The partnership provides for
depreciation of buildings and improvements on the straight-line method over
their estimated useful lives for financial and reporting purposes. For income
tax purposes, accelerated methods and lives are used.
 
  Deferred Costs
 
     Deferred costs are capitalized and amortized using the straight-line method
over the term of the related agreement.
 
  Rental Income
 
     Rental income is recognized as rents become due. Rental payments received
in advance are deferred until earned. All leases between the operating
partnership and tenants of the property are operating leases.
 
  Income Taxes
 
     No provision will be made for federal, state or local income taxes in the
financial statements of the partnership. Partners will be required to report on
their tax returns their allocable shares of income, gains, losses, deductions
and credits of the partnership.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents. At December 31, 1997, the carrying amount of $9,015 approximates
fair value because of the short maturity of this instrument.
 
NOTE B -- MORTGAGES PAYABLE
 
     On December 28, 1995, the partnership obtained two mortgage loans by the
same lender in the aggregate amount of $8,224,973 and are collateralized by
deeds of trust on the rental properties. The notes bear interest at a rate of
7.61%. Principal and interest are payable by the partnership in monthly
installments of $61,372. A balloon payment of approximately $7,222,801 and the
accrued interest is payable in full on December 29, 2002.
 
     Under agreements with the mortgage lender, the partnership is required to
make monthly escrow deposits for taxes and insurance.
 
     In addition, the partnership was required to make an initial deposit of
$246,000 into a repair escrow which is being held by Heritage Title Company. The
balance of the repair escrow at December 31, 1997 and 1996 is $34,743 and
$251,087, respectively.
 
     The liability of the partnership under the mortgage notes are limited to
the underlying value of the real estate collateral plus other amounts deposited
with the lender.
 
     Aggregate annual maturities of the mortgages payable over each of the next
five years are as follows:

To the Partners
Winthrop Texas Investors Limited Partnership
 
     We have audited the accompanying balance sheets of Winthrop Texas Investors
Limited Partnership as of December 31, 1995 and 1994, and the related statements
of income, partners' equity (deficit) and cash flows for the years then ended.
These financial statements are the responsibility of the partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Winthrop Texas Investors
Limited Partnership as of December 31, 1995 and 1994, and the results of its
operations, the changes in partners' equity (deficit) and cash flows for the
years then ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994
 
NOTE A -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Winthrop Texas Investors Limited Partnership (the "partnership"), a limited
partnership, was formed September 20, 1993 under the laws of the State of
Maryland to acquire, renovate, and operate two residential apartment complexes
(the "properties") consisting of a total of 454 market-rate rental apartment
units, located in Dallas and Fort Worth, Texas. The properties are situated on a
total of approximately 12.4 acres of land known as the Enfield Apartments (in
Dallas) and the Salem Park Apartments (in Fort Worth). Termination of the
partnership will occur on December 31, 2041 or earlier upon the occurrence of
certain events specified in the partnership agreement.
 
     The general partner is Two Winthrop Limited Partnership. The initial
limited partner was WFC Realty Co., Inc., which withdrew from the partnership
upon the first admission of investors. The partnership sold 128 limited
partnership units at $100,000 per unit.
 
  Basis of Accounting
 
     The accompanying financial statements have been prepared on the accrual
basis in accordance with generally accepted accounting principles.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Investment in Rental Property
 
     Rental property is carried at cost. The partnership provides for
depreciation of buildings and improvements on the straight-line method over
their estimated useful lives for financial and reporting purposes. For income
tax purposes, accelerated methods and lives are used.
 
  Deferred Costs
 
     Deferred costs are capitalized and amortized using the straight-line method
over the term of the related agreement as discussed in Note D.
 
  Rental Income
 
     Rental income is recognized as rents become due. Rental payments received
in advance are deferred until earned. All leases between the operating
partnership and tenants of the property are operating leases.
 
  Income Taxes
 
     No provision will be made for federal, state or local income taxes in the
financial statements of the partnership. Partners will be required to report on
their tax returns their allocable shares of income, gains, losses, deductions
and credits of the partnership.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the partnership considers all
highly liquid investments consisting of a money market fund to be cash
equivalents. At December 31, 1995, the carrying amount of $867,120 approximates
fair value because of the short maturity of this instrument.
 
NOTE B -- MORTGAGES PAYABLE
 
     On December 28, 1995, the partnership obtained two mortgage loans by the
same lender in the aggregate amount of $8,224,973 and are collateralized by
deeds of trust on the rental properties. The notes bear interest at a rate of
7.46%. Principal and interest are payable by the partnership in monthly
installments of $60,568. A balloon payment of approximately $7,321,816 and the
accrued interest is payable in full on December 29, 2002.
 
     Under agreements with the mortgage lender, the partnership is required to
make monthly escrow deposits for taxes and insurance.
 
     The liability of the partnership under the mortgage notes are limited to
the underlying value of the real estate collateral plus other amounts deposited
with the lender.
 
     The carrying amount of the partnership's long-term debt approximates fair
value.
 
     Aggregate annual maturities of the mortgages payable over each of the next
five years are as follows:

of $117,167 and $114,473 were charged to operations for 1995 and 1994,
respectively.
 
     An annual administration and investor service fee starting at $25,000 and
increasing by 6% per year will be paid to an affiliate of the general partner.
For the years ended December 31, 1995 and 1994, the amount of the fee paid by

Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4885
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4886
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Woodmere Associates, L.P. For each unit that you tender, you may choose to
     receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.

<PAGE>   4891
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral   %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   4892
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $0.00 per unit for the six months
     ended June 30, 1998 as a result of capital improvements to your
     partnership's property funded from cash flow. We will pay fixed quarterly
     distributions of $               per unit on the Tax-Deferral   % Preferred
     OP Units before any distributions are paid to holders of Tax-Deferral
     Common OP Units. We pay quarterly distributions on the Tax-Deferral Common
     OP Units based on our funds from operations for that quarter. For the six
     months ended June 30, 1998, we paid distributions of $1.125 on each of the
     Tax-Deferral Common OP Units (equivalent to $2.25 on an annual basis).
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION
 
                                       S-3
<PAGE>   4893
 
     THAT MAY BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF
     YOU ARE SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.

<PAGE>   4894
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-  of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   4897
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   4898
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   4899
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
 
                                      S-10
<PAGE>   4900
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The authorization and
issuance of preferred stock could have the effect of delaying or preventing
someone from taking control of us, even if a change in control were in our
stockholders' best interests. As a Maryland
 
                                      S-11
<PAGE>   4901
 
corporation, we are subject to various Maryland laws which may have the effect
of discouraging offers to acquire us and of increasing the difficulty of
consummating any such offers, even if our acquisition would be in our
stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least 67% of the outstanding units of the units
     of your partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership faces maturity or balloon payment dates on its mortgage loans
     and must either obtain refinancing or sell its property. If your
     partnership were to continue operating as presently structured, it could be
     forced to borrow on terms that could result in net losses from operations.
     In addition, continuation of your partnership without the offer would deny
     you and your partners the benefits that your general partner expects to
     result from the offer. For example, a partner of your partnership would
     have no opportunity for liquidity unless he were to sell his units in a
     private
 
                                      S-12
<PAGE>   4902
 
     transaction. Any such sale would likely be at a very substantial discount
     from the partner's pro rata share of the fair market value of your
     partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Preferred OP Units has prior
       distribution rights and the Tax-Deferral   % Preferred OP Units rank
       equal to six other outstanding classes of Preferred OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

withdrawn prior to the expiration date by any person holding one or fewer units
who tenders all of his or her units; and (2) second, all other units properly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis,
with adjustments to avoid resulting ownership of less than one unit by any
person. In the event that proration of tendered units is required, we will
determine the final proration factor as promptly as practicable after the
expiration date.

     Extension; Termination; Amendment. We expressly reserve the right, in our
sole discretion, at any time and from time to time, to:
 
     - extend the period of time during which the offer is open and thereby
       delay acceptance of, and payment for, any tendered units;
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
                                      S-14
<PAGE>   4904
 
     - upon the failure to satisfy any of the conditions to the offer, delay the
       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU

VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Price to Other Values. In evaluating the offer, your
general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.
 
     The results of these comparative analyses are summarized as follows:

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number
 
                                      S-17
<PAGE>   4907
 
of limited partner interests it may issue while the AIMCO Operating Partnership
is not subject to such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of 1% of the gross collected income from your partnership's property
of your partnership and may receive reimbursement for expenses generated in its
capacity as general partner. The property manager received management fees of
$50,000 in 1996, $52,000 in 1997 and $26,548 for the first six months of 1998.
We have no current intention of changing the fee structure for your property
manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Woodmere Associates, L.P. is a Delaware
limited partnership which was formed on May 28, 1985 for the purpose of owning
and operating a single apartment property located in Cincinnati, Ohio, known as
"Woodmere Apartments." In 1985, it completed a private placement of units that
raised net proceeds of approximately $1,887,000. Woodmere Apartments consists of
150 apartment units. Your partnership has no employees.
 
     Property Management. Since December 1991, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
 
                                      S-18
<PAGE>   4908
 
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2012, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $2,903,759, payable to Marine Midland,
Bank of America and FNMA, which bears interest at a rate of 7.60%. The mortgage
debt is due in November 2002. Your partnership also has a second mortgage note
outstanding of $103,182, on the same terms as the first mortgage note. Your
partnership's agreement of limited partnership also allows your general partner
to lend funds to your partnership. Currently, the general partner of your
partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

(a)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   4916
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights, title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units for purchase.
Accordingly, following the purchase of your units, we would be entitled to
receive any future distributions from the operations of your partnership to the
extent of the units we acquire. Similarly, if you tender your units for OP
Units, you will be entitled to future distributions from the operations of the
AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I Preferred Stock or the Class A Common Stock will trade
following the time at which Preferred OP Units or
 
                                      S-27
<PAGE>   4917
 
Common OP Units may be redeemed for shares of Class I Preferred Stock or Class A
Common Stock. Furthermore, the liquidity of the Class I Preferred Stock and the
Class A Common Stock at the time at which OP Units may be redeemed is also
uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $       , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions with respect to your
units are $0.00 as a result of capital improvements to your partnership's
property funded from cash flow. Therefore, distributions with respect to the
Preferred OP Units and Common OP Units that we are offering are expected to be
       , immediately following our offer, than the distributions with respect to
your units. See "Comparison of Ownership of Your Units and AIMCO OP
Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that
 
                                      S-28
<PAGE>   4918
 
AIMCO's access to the public markets may prove challenging in light of the
volatility in both the equity and capital markets for REITs. Moody's assigned a
"ba3" rating to the Class I Preferred Stock proposed to be issued by AIMCO, and
confirmed its previous ratings related to AIMCO's preferred stock and debt in
its shelf registration statement. Moody's indicated that its rating action
continues to reflect AIMCO's increasing leveraged profile, including high levels
of secured debt and preferred stock, limited financial flexibility and
integration risks resulting from the merger with Insignia. Moody's also noted
AIMCO's high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which AIMCO owns a general partnership
interest. At the same time, Moody's confirmed its existing rating on AIMCO's
existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for investment, business, personal or other purposes, at
their option. If your partnership were to sell its assets and liquidate, you and
your partners would not need to rely upon capitalization of income or other
valuation methods to estimate the fair market value of your partnership's
assets. Instead, such assets would be valued through negotiations with
prospective purchasers (in many cases unrelated third parties).
 
                                      S-29
<PAGE>   4919
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least 67% of the outstanding units of the units of your
partnership. In the absence of such consent, your only option for liquidation
would be to sell your units in a private transaction. Any such sale likely would
be at a very substantial discount from your pro rata share of the fair market
value of your partnership's property and might involve significant expense and
delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership faces maturity or balloon payment dates on its mortgage
loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral   % Preferred OP Units rank equal to five other
       outstanding classes of Partnership Preferred Units.
 
                                      S-30
<PAGE>   4920
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.

     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   4923
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.

<PAGE>   4924
 
 Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation
 to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.
 
                                      S-35
<PAGE>   4925
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   4927
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.

     Section 13(d)(3) of the Securities Exchange Act of 1934), or it shall have
     been publicly disclosed or the AIMCO Operating Partnership shall have
     otherwise learned that (i) any person or group shall have acquired or
     proposed or be attempting to acquire beneficial ownership of more than four
     percent of the units, or shall have been granted any option, warrant or
     right, conditional or otherwise, to acquire beneficial ownership of more
     than four percent of the units, or (ii) any person or group shall have
     entered into a definitive agreement or an agreement in principle or made a

     the AIMCO Operating Partnership shall not have adequate cash or financing
     commitments available to pay the cash portion of the offer consideration.

Partnership and may be asserted by the AIMCO Operating Partnership regardless of

Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or

circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
 
                                      S-40
<PAGE>   4930
 
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred
 
                                      S-42
<PAGE>   4932
 
     OP Units that are issued after the date of original issuance are entitled
to receive the same distributions as holders of any Preferred OP Units issued on
the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
 
                                      S-43
<PAGE>   4933
 
     involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

<PAGE>   4934
 
                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or in the future jeopardize AIMCO's
status as a REIT. As a condition of such waiver, the AIMCO board of
 
                                      S-45
<PAGE>   4935
 
     directors may require opinions of counsel satisfactory to it and/or an
undertaking from the applicant with respect to preserving the REIT status of
AIMCO. If shares of Class I Preferred Stock in excess of the Class I Preferred
Ownership Limit, or shares of Class I Preferred Stock which would result in
AIMCO being "closely held," within the meaning of Section 856(h) of the Code, or
which would otherwise result in AIMCO failing to qualify as a REIT, are issued
or transferred to any person, such issuance or transfer will be null and void to
the intended transferee, and the intended transferee would acquire no rights to
the Class I Preferred Stock. Shares of Class I Preferred Stock transferred in
excess of the Class I Preferred Ownership Limit or other applicable limitations
will automatically be transferred to a trust for the exclusive benefit of one or
more qualifying charitable organizations to be designated by AIMCO. Shares
transferred to such trust will remain outstanding, and the trustee of the trust
will have all voting and dividend rights pertaining to such shares. The trustee
of such trust may transfer such shares to a person whose ownership of such
shares does not violate the Class I Preferred Ownership Limit or other
applicable limitation. Upon a sale of such shares by the trustee, the interest
of the charitable beneficiary will terminate, and the sales proceeds would be
paid, first, to the original intended transferee, to the extent of the lesser of
(a) such transferee's original purchase price (or the original market value of
such shares if purportedly acquired by gift or devise) and (b) the price
received by the trustee, and, second, any remainder to the charitable
beneficiary. In addition, shares of Class I Preferred Stock held in such trust
are purchasable by AIMCO for a 90-day period at a price equal to the lesser of
the price paid for the Class I Preferred Stock by the original intended
transferee (or the original market value of such shares if purportedly acquired
by gift or devise) and the market price for the Class I Preferred Stock on the
date that AIMCO determines to purchase the Class I Preferred Stock. The 90-day
period commences on the date of the violative transfer or the date that the
AIMCO board of directors determines in good faith that a violative transfer has
occurred, whichever is later. All certificates representing shares of Class I
Preferred Stock bear a legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,

the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
 
                                      S-50
<PAGE>   4940
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
 
                                      S-51
<PAGE>   4941
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   4943
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   4944
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the cash offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Based on anticipated annualized distributions of $     with respect
     to the Preferred OP Units, current annualized distributions of $2.25 with
     respect to the Common OP Units and the 1998 distributions of $0.00 with
     respect to your units due to capital improvements on your partnership's
     property funded from cash flow, distributions with respect to the Preferred
     OP Units and Common OP Units being offered are expected to be      ,
     immediately following the offer, than the distributions with respect to
     your units. See "Comparison of Ownership of Your Units and AIMCO OP
     Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
partner of your partnership and the AIMCO Operating Partnership believe that the
valuation method described in "Valuation of Units" provides a meaningful
indication of value for residential apartment
 
                                      S-55
<PAGE>   4945
 
     properties although there are other ways to value real estate. A
liquidation in the future might generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
your partnership's property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

<PAGE>   4946
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.
 
     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.

     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   4949
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of your partnership or all
or any part of your partnership; or (iv) express any opinion as to (a) the tax
consequences of the offer to unitholders, (b) the terms of your partnership's
agreement of limited partnership or the terms of any agreements or contracts
between your partnership or AIMCO; (c) AIMCO's or the general partner's business
decision to effect the offer, or alternatives to the offer, (d) the amount or
allocation of expenses relating to the offer between AIMCO and your partnership
or tendering unitholders; (e) the relative value of the cash, Preferred OP Units
or Common OP Units to be issued in connection with the offer; and (f) any
adjustments made to determine the offer consideration and the net amounts
distributable to the unitholders, including but not limited to, balance sheet
adjustments to reflect your partnership's estimate of the value of current net
working capital balances, reserve accounts, and liabilities, and adjustments to
the offer consideration for distributions made by your partnership subsequent to
the date of the offer.
 
     Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed offer
could affect the partnership's property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
 
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
A-1.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives an
annual fee of 1% of the gross collected income from your partnership's property
from your partnership and may receive reimbursement for expenses generated as
general partner. The property manager received management fees of $50,000 in
1996, $52,000 in 1997 and $26,548 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Woodmere Associates, L.P. is a Delaware limited partnership which raised
net proceeds of approximately $1,887,000 in 1985 through a private offering. The
promoter for the private offering of your partnership was Jacques-Miller.
Insignia acquired your partnership in December 1991. AIMCO acquired Insignia in
October, 1998. There are currently a total of 41 limited partners of your
partnership and a total of 51 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property
described below. Your partnership has no employees.
 
YOUR PARTNERSHIP AND ITS PROPERTY
 
     Your partnership was formed on May 28, 1985 for the purpose of owning and
operating a single apartment property located in Cincinnati, Ohio, known as
"Woodmere Apartments." Your partnership's property consists of 150 apartment
units. The total rentable square footage of your partnership's property is
147,126 square feet. Your partnership's property had an average occupancy rate
of approximately 92.67% in 1996 and 92.67% in 1997. The average annual rent per
apartment unit is approximately $6,536.
 
     Your partnership's property provides residents with a number of amenities
and services, such as 24-hour desk service, exercise room and/or sauna, and
party or meeting rooms. Nearly all apartment units are wired for cable
television, and many apartment units also offer one or more additional features,
such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1991, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $50,000, $52,000 and $26,548, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2012
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

CAPITAL REPLACEMENT
 
     Your partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
 
BORROWING POLICIES
 
     Your partnership's agreement of limited partnership allows your partnership
to incur debt. [As of June 30, 1998, your partnership had a current mortgage
note outstanding of $2,903,759, payable to Marine Midland, Bank of America and
FNMA, which bears interest at a rate of 7.60%. The mortgage debt is due in
November 2002. Your partnership also has a second mortgage note outstanding of
$103,182, on the same terms as the first mortgage note. Your partnership's
agreement of limited partnership also allows the general partner of your
partnership to lend funds to your partnership. Currently, the general partner of
your partnership has no loan outstanding to your partnership.
 
COMPETITION
 
     There are other residential properties within the market area of your
partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.
 
LEGAL PROCEEDINGS
 
     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on your partnership.

ended June 30, 1998 compared to $9,816 for the six months ended June 30, 1997,

training, travel and office supplies.

costs, totaled $115,302 for the six months ended June 30, 1998, compared to

     Your partnership recognized net income of $73,000 for the year ended
December 31, 1997, compared to a net loss of $1,000 for the year ended December
31, 1996. The increase in net income of $74,000, or 7,400% was primarily the
result of an increase in rental revenue in conjunction with a decrease in
operating expenses. These factors are discussed in more detail in the following
paragraphs.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,057,000 for the year ended December 31, 1997, compared to $1,013,000 for the
year ended December 31, 1996, an increase of $44,000, or 4.34%.

received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, property taxes and insurance, totaled
$482,000 for the year ended December 31, 1997, compared to $554,000 for the year
ended December 31, 1996, a decrease of $72,000 or 13%. This is due to the
property incurred non-capitalized parking lot repair and exterior painting
expenses in 1996. Management expenses totaled $52,000 for the year ended
December 31, 1997, compared to $50,000 for the year ended December 31, 1996, an
increase of $2,000, or 4.00%.
 
     General and administrative expenses totaled $36,000 for the year ended
December 31, 1997 compared to $10,000 for the year ended December 31, 1996, an
increase of $26,000 or 260%. The increase is primarily due to expenses included
in operating expense for 1996 were reclassed to general administrative expenses
for 1997. These reclassed expenses relate to audit fees and general partner
reimbursements.
 
     Interest Expense

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $173,986 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership will
not incur any liability to your partnership or any limited partner for any
mistakes or errors in judgment or for any acts or omission believed by the
general partner in good faith to be within the scope of authority conferred upon
it by your partnership agreement. As a result, unitholders might have a more
limited right of action in certain circumstances than they would have in the
absence of such a provision in your partnership's agreement of limited
partnership. The general partner of your partnership is owned by AIMCO. See
"Conflicts of Interest."
 
     Your partnership will, to the extent permitted by law, indemnify and save
harmless the general partner against and from any personal loss, liability
(including attorneys' fees) or damage incurred by it as the result of any act or
omission in its capacity as general partner unless such loss, liability or
damage results from gross negligence or willful misconduct by the general
partner. As part of its assumption of liabilities in the consolidation, AIMCO
will indemnify the general partner of your partnership and their affiliates for
periods prior to and following the consolidation to the extent of the indemnity
under the terms of your partnership's agreement of limited partnership and
applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.
 
DISTRIBUTIONS AND TRANSFERS OF UNITS
 
  Distributions
 
     The following table sets forth the distributions paid per unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of your partnership during the preceding quarter. Your
partnership did not pay distributions in 1997 and is not expected to pay
distributions in 1998 due to capital improvements to your partnership's property
funded from cash flow.

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
there have been no units transferred in sale

of loans, guarantees against loss or the giving or withholding of proxies.

property manager or AIMCO and its affiliates.

NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Woodmere Associates, LP
as of June 30, 1998 and for the six months ended June 30, 1998 and 1997 have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for a fair presentation have been included and all such
adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that accounting measurements at interim dates inherently
involve greater reliance on estimates than at year-end. The results of
operations for the interim periods presented are not necessarily indicative of
the results for the entire year.

                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Woodmere Associates, L.P., is a Delaware limited partnership which began
operations in 1985 with the purchase of an apartment complex in Cincinnati,
Ohio. The Partnership's Managing General Partner is Jacques-Miller Associates.
 
  Investment Property
 
     The investment property is recorded at the Partnership's acquisition cost.
Buildings and related personal property are depreciated using the straight-line
method over the estimated useful lives of the assets, ranging from 5 to 25
years.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Income Taxes
 
     No provision has been made for Federal and state income taxes since such
taxes are the personal responsibility of the partners.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from these estimates.
 
  Partnership Allocations
 
     Net earnings or loss and taxable income or loss are allocated 99% to the
limited partners and 1% to the general partners. Distributions of available cash
or proceeds from financing or sale of the property are allocated among the
limited partners and the general partners in accordance with the limited
partnership agreement.
 
  Cash and Cash Equivalents
 
     It is the Partnership's policy to classify all liquid short-term
investments with a maturity of three months or less as cash equivalents. At
certain times, the amount of cash deposited at a bank may exceed the limit on
insured deposits.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all apartment lessees for
the duration of the lease and includes the deposits in "Receivables and
deposits". Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit and the tenant is current on its rental payments.
 
  Restricted Escrows -- Reserve Account
 
     At the time of the refinancing of the mortgage notes payable in 1992, the
Reserve Escrow was established with the refinancing proceeds. These funds were
established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. The Partnership is required to deposit

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
net operating income (as defined in the mortgage note) from the refinanced
property to the reserve account until the reserve account equals $1,000 per
apartment unit or $150,000 in total. At December 31, 1997, the reserve account
balance was approximately $160,000.
 
  Loan Costs
 
     In connection with the refinancing of certain mortgage notes payable in
1992, loan costs of approximately $123,000 were incurred which are being
amortized on a straight-line basis over the life of the loans. Accumulated
amortization as of December 31, 1997, is approximately $63,000.

     Mortgages are collateralized by the related property and improvements of
the Partnership.
 
     The Partnership exercised interest rate buy-down options when the debt was
refinanced, reducing the stated rate from 8.76% to 7.60%. The fee for the
interest rate reduction amounted to approximately $239,000 and is being
amortized as a loan discount on the interest method over the life of the loans.
The discount fee is reflected as a reduction of the mortgage notes payable and
increases the effective rate of the debt to 8.76%.

                         REPORT OF INDEPENDENT AUDITORS
 
Members of the Partnership
Woodmere Associates, L.P.
 
     We have audited the accompanying balance sheet of Woodmere Associates,
L.P., as of December 31, 1996, and the related statements of operations,
partners' deficit and cash flows for the year then ended. These financial
statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Woodmere Associates, L.P. as
of December 31, 1996, and the results of its operations and its cash flows for
the year then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Woodmere Associates, L.P., is a Delaware limited partnership which began
operations in 1985 with the purchase of an apartment complex in Cincinnati,
Ohio. The Partnership's Managing General Partner is Jacques-Miller Associates.
 
  Investment Property
 
     The investment property is recorded at the Partnership's acquisition cost.
In 1995 the Partnership adopted Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of", which requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount. The impairment loss is measured by
comparing the fair value of the asset to its carrying amount. The effect of
adoption was not material. Buildings and related personal property are
depreciated using the straight-line method over the estimated useful lives of
the assets, ranging from 5 to 25 years.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Income Taxes
 
     No provision has been made for Federal and state income taxes since such
taxes are the personal responsibility of the partners.
 
  Fair Value
 
     In 1995, the Partnership implemented Statement of Financial Accounting
Standards No. 107, "Disclosure about Fair Value of Financial Instruments," which
requires disclosure of fair value information about financial instruments for
which it is practical to estimate that value. The carrying amount of the
Partnership's cash and cash equivalents approximates fair value due to
short-term maturities. The Partnership estimates the fair value of its fixed
rate mortgages by discounted cash flow analysis, based on estimated borrowing
rates currently available to the Partnership (Note B).
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from these estimates.
 
  Partnership Allocations
 
     Net earnings or loss and taxable income or loss are allocated 99% to the
limited partners and 1% to the general partners. Distributions of available cash
or proceeds from financing or sale of the property are allocated among the
limited partners and the general partners in accordance with the limited
partnership agreement.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash and Cash Equivalents -- Unrestricted Cash
 
     It is the Partnership's policy to classify all liquid short-term
investments with a maturity of three months or less as cash equivalents. At
certain times, the amount of cash deposited at a bank may exceed the limit on
insured deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all apartment lessees for
the duration of the lease and consider the deposits to be restricted cash.
Deposits are refunded when the tenant vacates the apartment if there has been no
damage to the unit.
 
  Restricted Escrows -- Reserve Account
 
     At the time of the refinancing of the mortgage notes payable in 1992, the
Reserve Escrow was established with the refinancing proceeds. These funds were
established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. The Partnership is required to deposit net operating income (as
defined in the mortgage note) from the refinanced property to the reserve
account until the reserve account equals $1,000 per apartment unit or $150,000
in total. At December 31, 1996, the reserve account balance was $153,000.
 
  Loan Costs
 
     In connection with the refinancing of certain mortgage notes payable in
1992, loan costs of $123,000 were incurred which are being amortized on a
straight-line basis over the life of the loans. Accumulated amortization as of
December 31, 1996 is $50,000.

</TABLE>
 
     Mortgages are collateralized by the related property and improvements of
the Partnership.
 
     The Partnership exercised interest rate buy-down options when the debt was
refinanced, reducing the stated rate from 8.76% to 7.60%. The fee for the
interest rate reduction amounted to $239,000 and is being amortized as a loan
discount on the interest method over the life of the loans. The discount fee is
reflected as a reduction of the mortgage notes payable and increases the
effective rate of the debt to 8.76%.
 
     The carrying value of the mortgage notes payable approximates its estimated
fair value at December 31, 1996.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Woodmere Associates, L.P., (an apartment complex) is a Delaware limited
partnership which began operations in 1985 with the purchase in Cincinnati,
Ohio.
 
  Investment Property
 
     The investment property is recorded at the Partnership's acquisition cost.
In 1995 the Partnership adopted FASB Statement No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. The impairment loss is measured by comparing the fair value of
the asset to its carrying amount. The effect of adoption was not material.
Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over estimated service lives, using the
straight-line method.
 
  Income Taxes
 
     No provision has been made for Federal and state income taxes since such
taxes are the personal responsibility of the partners.
 
  Fair Value
 
     In 1995, the Partnership implemented Statement of Financial Accounting
Standards No. 107, "Disclosure about Fair Value of Financial Instruments," which
requires disclosure of fair value information about financial instruments for
which it is practical to estimate that value. The carrying amount of the
Partnership's cash and cash equivalents approximates fair value due to
short-term maturities. The Partnership estimates the fair value of its fixed
rate mortgages by discounted cash flow analysis, based on estimated borrowing
rates currently available to the Partnership (Note 2).
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from these estimates.
 
  Partnership Allocations
 
     Net earnings or loss and taxable income or loss are allocated 99% to the
limited partners and 1% to the general partners. Distributions of available cash
or proceeds from financing or sale of the property are allocated among the
limited partners and the general partners in accordance with the limited
partnership agreement.
 
  Cash and Cash Equivalents
 
     It is the Partnership's policy to classify all liquid short-term
investments with a maturity of three months or less as cash equivalents.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Restricted Escrows
 
     1) Capital Improvement Reserves
 
     At the time of the refinancing of Woodmere Associates, L.P. mortgage note
payable in 1992, $65,300 of the proceeds were designated for a "capital
improvement escrow" for certain capital improvements. At December 31, 1995,
approximately $49,000 of the reserves had been expended. The capital
improvements are anticipated to be completed in calendar year 1996 and any
excess funds will be returned for property operations.
 
     2) Reserve Account
 
     In addition to the Capital Improvement Reserve, the Reserve Escrow was
established with the refinancing proceeds for the refinanced property. These
funds were established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. The Partnership is required to deposit net operating income (as
defined in the mortgage note) from the refinanced property to the reserve
account until the reserve account equals $1,000 per apartment unit or $150,000
in total. At December 31, 1995, the reserve account balance was $152,578.
 
  Loan Costs
 
     In connection with the refinancing of certain mortgage notes payable in
1992, loan costs of $123,468 were incurred which are being amortized on a
straight-line basis over the life of the loans.
 
2. MORTGAGE NOTES PAYABLE
 
     The principal terms of mortgage notes payable are as follows:

</TABLE>
 
     Mortgages are collateralized by the related property and improvements of
the Partnership.
 
     Total interest paid during fiscal 1995 was $247,794.
 
     The Partnership exercised interest rate buy-down options when the debt was
refinanced, reducing the stated rate from 8.76% to 7.60%. The fee for the
interest rate reduction amounted to $239,388 and is being amortized as a loan
discount on the interest method over the life of the loans. The discount fee is
reflected as a reduction of the mortgage notes payable and increases the
effective rate of the debt to 8.76%.
 
     The carrying value of the mortgage notes payable approximates its estimated
fair value at December 31, 1995.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       A-1
<PAGE>   4997
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   4998
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,

                     QUESTIONS AND ANSWERS ABOUT THE OFFER
 
Q:   WHAT AM I BEING OFFERED?
 
A:   We are offering to acquire your units of limited partnership interest in
     Yorktown Towers Associates. For each unit that you tender, you may choose
     to receive                of our Tax-Deferral      % Partnership Preferred
     Units (also referred to as "Preferred OP Units"),                of our
     Tax-Deferral Partnership Common Units (also referred to as "Common OP
     Units"), or $          in cash (subject, in each case to adjustment for any
     distributions paid to you during the offer period). If you like, you can
     choose to keep any or all of your units.
 
Q:   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS IF I SELL MY UNITS?
 
A:   No.
 
Q:   WHO IS AIMCO PROPERTIES, L.P.?
 
A:   AIMCO Properties, L.P. is the operating partnership which conducts
     substantially all of the operations of Apartment Investment and Management
     Company, a real estate investment trust ("AIMCO"). As of October 1, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 396,090 apartment units in
     2,303 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of June 30, 1998, AIMCO had total assets of $3,055 million, total
     debt of $1,314 million and stockholders' equity of $1,394 million. On a pro
     forma basis, giving effect to our recently completed merger with Insignia
     Financial Group, Inc. and related transactions, as of June 30, 1998, AIMCO
     had total assets of $3,972 million, total debt of $1,626 million and
     stockholders' equity of $1,844 million.
 
Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
 
A:   On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
     so, we acquired the managing general partner of your partnership (the
     "general partner") and the company that manages the property owned by your
     partnership.
 
Q:   WHY IS THE OFFER BEING MADE?
 
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.
 
Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
 
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the National Association of
     Securities Dealers Automated Quotations System (also referred to as the
     "NASDAQ System"). There is no active trading market for Tax-Deferral   %
     Preferred OP Units and none is likely to develop because they are subject
     to restrictions on transfer. However, after a one-year holding period, a
     holder of Tax-Deferral      % Preferred OP Units may redeem his or her
     units for shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
     Class A Common Stock or cash, at our option. AIMCO's Class A Common Stock
     is, and AIMCO's Class I Preferred Stock is expected to be, listed and
     traded on the New York Stock Exchange (also referred to as the "NYSE").
 
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
 
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash.
 
                                       S-1
<PAGE>   5003
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. However, one class of outstanding Partnership
       Preferred Units has prior distribution rights and the Tax-Deferral      %
       Preferred OP Units rank equal to six other outstanding classes of
       Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
 
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer. However, after a one-year holding
     period, a holder of Tax-Deferral Common OP Units may redeem his or her
     units for shares of AIMCO's Class A Common Stock (on a one-for-one basis,
     subject to adjustment in certain circumstances) or, at our option, an
     equivalent amount of cash. AIMCO's Class A Common Stock is listed and
     traded on the New York Stock Exchange under the symbol "AIV." On October 5,
     1998, the last reported sale price of AIMCO Class A Common Stock on the New
     York Stock Exchange was $       . The following table shows the high and
     low reported sales prices and dividends declared per share of AIMCO's Class
     A Common Stock for the periods indicated. The table also shows the
     distributions per unit declared on the Tax-Deferral Common OP Units for the
     same periods.

Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
 
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock or an equivalent amount of cash.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
                                       S-2
<PAGE>   5004
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Historically, the quarterly
       distributions paid on the Tax-Deferral Common OP Units have been
       equivalent to the dividends paid on AIMCO's Class A Common Stock. We
       expect this to continue in the future.
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
 
A:   There are two principal advantages of tendering units for cash:
 
     - Immediate liquidity. If you tender your units for cash, you will receive
       $     per unit. However, tendering your units for cash may cause you to
       recognize taxable gain for Federal income tax purposes.
 
     - Ease of tax reporting. After this year, you will not receive a Schedule
       K-1 tax form containing tax information used for preparing your Federal
       income tax return. This may simplify the preparation of your tax return.
 
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
 
A:   Your partnership paid distributions of $3,543.69 per unit for the six
     months ended June 30, 1998 (equivalent to $7,087.38 on an annual basis). We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units based on our funds from operations for
     that quarter. For the six months ended June 30, 1998, we paid distributions
     of $1.125 on each of the Tax-Deferral Common OP Units (equivalent to $2.25
     on an annual basis). This is equivalent to distributions of $          per
     year on the number of Tax-Deferral      % Preferred OP Units, or
     distributions of $          per year on the number of Tax-Deferral Common
     OP Units, that you would receive in an exchange for each of your
     partnership's units.
 
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
 
A:   We determined our offer consideration without any arms-length negotiations.
     Thus, the offer consideration may not necessarily reflect the value of your
     units if they were sold to someone else or if the assets of your
     partnership were liquidated and the net proceeds distributed to you and
     your partners. If you tender your units for cash, you may have to pay
     taxes. If you tender your units in exchange for Tax-Deferral   % Preferred
     OP Units or Tax-Deferral Common OP Units, the nature of your investment
     will change from holding an interest in a single apartment property to
     holding an interest in an operating business that owns and manages a large
     portfolio of properties, with risks that do not exist for your partnership.
     You should review the risk factors in this Prospectus Supplement and in the
     accompanying Prospectus.
 
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
 
A:   You will generally not recognize any immediate taxable gain or loss for
     Federal income tax purposes if you exchange your units solely for
     Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units. You
     will generally recognize a taxable gain or loss for Federal income tax
     purposes on units you sell for cash. The exchange of your units for cash
     and OP Units will be treated, for Federal income tax purposes, as a partial
     sale of such units for cash, and as a partial tax-free contribution of such
     units to our operating partnership.

     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
 
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
 
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership's agreement of limited
     partnership, seek a private sale of your units. However, your partnership's
     agreement of limited partnership contains certain restrictions on the
     resale of your units, and the market for your units may be limited. Your
     partnership's agreement of limited partnership prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
 
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
 
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.
 
Q:   WHAT ARE MY UNITS WORTH?
 
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer consideration is fair. However, your units
     are not listed on any national securities exchange nor quoted on the NASDAQ
     System, and there is no established trading market for your units.
     Secondary sales activity for the units has been limited and sporadic. Your
     general partner does not monitor or regularly receive or maintain
     information regarding the prices at which secondary sale transactions in
     the units have been effectuated.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   We determined the cash offer consideration by estimating the proceeds that
     you would receive if your partnership were liquidated. For this purpose, we
     estimated the value of the property owned by your partnership using the
     direct capitalization method. This method involves applying a
     capitalization rate to your partnership's annual net operating income. We
     determined an appropriate capitalization rate using our best judgment, but
     our valuation is just an estimate. Although the direct capitalization
     method is a widely-accepted way of valuing real estate, there are a number
     of other methods available to value real estate, each of which may result
     in different valuations of the property. The proceeds that you would
     receive if you sold your units to someone else or if your partnership were
     actually liquidated might be higher or lower than our offer consideration.
     An actual liquidation may also result in your paying taxes.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL   % PREFERRED OP UNITS TO
     BE OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $100 liquidation preference
     of the Tax-Deferral   % Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF TAX-DEFERRAL COMMON OP UNITS TO BE
     OFFERED IN EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents 100% of
     the closing price of the AIMCO Class A Common Stock on the NYSE on a recent
     date prior to our commencement of this offer.
 
                                       S-4
<PAGE>   5006
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
 
A:   We have retained Robert A. Stanger & Co., Inc. ("Stanger") to conduct an
     analysis of the offer and to render an opinion as to the fairness to you of
     the offer consideration. Stanger is not affiliated with us or your general
     partner. Stanger is one of the leaders in the field of analyzing and
     evaluating complex real estate transactions. However, we provided much of
     the information used by Stanger in evaluating our offer. We believe that
     the information we provided to Stanger is accurate.
 
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
 
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.
 
Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
 
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
 
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
 
A:   You should feel free to contact the Information Agent as set forth below:

                                    SUMMARY
 
     This summary highlights some of the information in this Prospectus
Supplement and the accompanying Prospectus.
 
THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company, or "AIMCO". AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. As of
October 1, 1998, our portfolio of owned or managed properties included 396,090
apartment units in 2,303 properties located in 49 states, the District of
Columbia and Puerto Rico. Based on apartment unit data compiled as of January 1,
1998 by the National Multi Housing Council, we believe that this made us the
largest owner and manager of multifamily apartment properties in the United
States. As of October 1, 1998, we:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     Our principal executive offices are located at 1873 South Bellaire Street,
Denver, Colorado 80222, and our telephone number is (303) 757-8101.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     -        of our Tax-Deferral      % Preferred OP Units;
 
     -        of our Tax-Deferral Common OP Units; or
 
     - $          in cash;
 
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
 
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
 
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-26 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer:
 
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the exchange ratios and the cash
consideration, without any arms-length negotiations. We have retained Robert A.
Stanger & Co., Inc. to conduct an analysis of our offer and to render an opinion
as to the fairness to you of our offer consideration, from a financial point of
view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon
 
                                       S-7
<PAGE>   5009
 
a future liquidation of your partnership. Accordingly, you might receive more
value if you retain your units until your partnership is liquidated. However,
you may prefer to receive the offer consideration now rather than wait for
uncertain future net liquidation proceeds.
 
     OFFER CONSIDERATION MAY NOT NECESSARILY REPRESENT FAIR MARKET VALUE. There
is no established or regular trading market for your units, nor is there another
reliable standard for determining the fair market value of the units. If you
need or desire liquidity, you may wish to consider the offer. However, the offer
consideration does not necessarily reflect the price that you would receive in
an open market for your units or upon a liquidation of your partnership's
assets. Such prices could be higher or lower than the offer consideration.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our Preferred OP Units or Common OP Units ("OP Units") in exchange for
your units, you will be entitled to future distributions from us.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
solely for our OP Units, it will not be a taxable transaction. If you sell your
units for cash, you will recognize taxable gain or loss in an amount equal to
the difference between the amount realized on the sale and your adjusted tax
basis in your units. If you exchange your units for both cash and OP Units, it
will be treated, for Federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both cash and OP
Units, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for Federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, your tax
liability resulting from such gain could exceed the amount of cash you receive
from us. See "Certain Federal Income Tax Matters."
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences to you of the exchange will depend upon a number of
factors related to your individual tax situation, including your tax basis in
your units, whether you dispose of all of your units in your partnership, and
whether the "passive loss" rules apply to your investments. Because the income
tax consequences of an exchange of units will not be the same for everyone, you
should consult your tax advisor before determining whether to tender your units
pursuant to our offer.
 
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders" in the accompanying Prospectus.
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
apartment property to an interest in a partnership that invests in and manages a
large portfolio of properties.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been fluctuations in
the trading prices for many real estate investment trust ("REIT") equity
securities, including ours.
 
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
 
                                       S-8
<PAGE>   5010
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership prohibits any transfer of an interest if such
transfer, together with all other transfers during the preceding 12 months,
would cause 50% or more of the total interest in your partnership to be
transferred within such 12-month period. If we acquire a significant percentage
of the interest in your partnership, you may not be able to transfer your units
for a 12-month period following our offer.
 
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
 
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
 
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. We have adopted certain policies designed to minimize or
eliminate the conflicts of interest inherent in these transactions, including a
requirement that a majority or our disinterested directors approve certain
transactions with affiliates. However, there can be no assurance that these
policies will be successful in eliminating the influence of such conflicts.
Furthermore, such policies are subject to change without the approval of our
stockholders.
 
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the general partner of the AIMCO Operating Partnership and its
affiliates, on the one hand, and the AIMCO Operating Partnership or any partner
thereof, on the other. The directors and officers of the general partner of the
AIMCO Operating Partnership have fiduciary duties to AIMCO, as its sole
stockholder. At the same time, as general partner of the AIMCO Operating
Partnership, it has fiduciary duties to the AIMCO Operating Partnership's
partners.
 
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership's agreement of limited
partnership restricts the transferability of OP Units. We have no plans to list
the OP Units on a securities exchange. It is unlikely that any person will make
a market in the OP Units, or that an active market for the OP Units will
develop.
 
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. The AIMCO Operating
Partnership is managed and operated by its general partner. Unlike the holders
of common stock in a corporation, holders of OP Units have only limited voting
rights on matters affecting the AIMCO Operating Partnership's business. Holders
of OP Units have no right to elect the general partner on an annual or other
continuing basis, and the general partner may not be removed by holders of OP
Units. As a result, holders of OP Units have limited influence on matters
affecting the operation of the AIMCO Operating Partnership and third parties may
find it difficult to attempt to gain control or influence the activities of our
operating partnership.
 
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
 
     POSSIBLE INCREASE IN CONTROL BY AIMCO. As a result of the offer, we may
increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
 
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
 
                                       S-9
<PAGE>   5011
 
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
 
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of owned and/or managed
properties from 132 properties with 29,343 units to 2,303 properties with
396,090 units. These acquisitions have included purchases of properties,
interests in entities that own or manage properties and corporate mergers. The
recent Insignia merger is our largest acquisition so far. We can provide no
assurance that we will be able to successfully integrate any acquired businesses
or properties.
 
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We often acquire
interests in limited partnerships that own apartment properties. In some cases,
we have acquired the general partner of a partnership and then made an offer to
acquire the limited partners' interests in the partnership. In these
transactions, we are sometimes subject to litigation based on claims that the
general partner has breached its fiduciary duties to its limited partners or
that the transaction violates the relevant partnership agreement.
 
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. If we fail
to make required payments of principal and interest on any debt, our lenders
could foreclose on the properties securing such debt with a consequent loss of
income and asset value to us.
 
     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. Recently,
Moody's Investors Service ("Moody's") revised its outlook for the ratings of
AIMCO from stable to negative to reflect its concerns surrounding AIMCO's
ability to successfully implement its financial strategy while maintaining a
prudent capital structure as a result of more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs and assigned a "ba3" rating to the Class I Preferred Stock proposed to
be issued by AIMCO. At the same time, Moody's confirmed its existing rating on
AIMCO's preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
 
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
 
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our investors unless
certain financial tests or other criteria are satisfied. In some cases, our
subsidiaries are subject to similar provisions, which may restrict their ability
to make distributions to us.
 
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. Many
of our properties are owned by subsidiaries. As a result, we depend on
distributions and other payments from the subsidiaries in order to satisfy our
financial obligations and make payments to our investors. The ability of the
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
 
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or
 
                                      S-10
<PAGE>   5012
 
rental rates, increases in operating costs, and changes in governmental
regulations and the related costs of compliance.
 
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties.
 
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
 
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. We own interests in or
manage many properties that benefit from governmental programs intended to
provide housing to people with low or moderate incomes. As a condition to the
receipt of assistance under these programs, the properties must comply with
various requirements, which typically limit rents to pre-approved amounts. If
permitted rents on a property are insufficient to cover costs, a sale of the
property may become necessary, which could result in a loss of management fee
revenue.
 
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
 
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with our Chairman, our President and one of our Executive
Vice Presidents, the loss of any of their services could have an adverse effect
on our operations.
 
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
 
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
 
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
 
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
 
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF AIMCO. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our board of directors. Under our charter, our board of directors has
the authority to classify and reclassify any of our unissued shares of capital
stock into shares of preferred stock with such preferences, rights, powers and
restrictions as our board of directors may determine. The
 
                                      S-11
<PAGE>   5013
 
authorization and issuance of preferred stock could have the effect of delaying
or preventing someone from taking control of us, even if a change in control
were in our stockholders' best interests. As a Maryland corporation, we are
subject to various Maryland laws which may have the effect of discouraging
offers to acquire us and of increasing the difficulty of consummating any such
offers, even if our acquisition would be in our stockholders' best interests.
 
BACKGROUND AND REASONS FOR THE OFFER
 
  Background of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
 
     On October 1, 1998, we merged with Insignia Financial Group, Inc. In doing
so, we acquired the general partner of your partnership and the company that
manages the property owned by your partnership. We currently do not own any
limited partnership interest in your partnership.
 
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer
consideration. We chose Stanger based on Stanger's expertise and strong
reputation in this area of work. On August 28, 1998, we entered into an
agreement with Stanger to provide such a fairness opinion for your partnership
and other partnerships.
 
  Alternatives Considered
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
 
        Liquidation. One alternative to our offer would be for your partnership
     to sell its assets, distribute the net liquidation proceeds to its partners
     in accordance with your partnership's agreement of limited partnership, and
     then dissolve. Partners would be at liberty to use the net liquidation
     proceeds after taxes for investment, business, personal or other purposes,
     at their option. If your partnership were to sell its assets and liquidate,
     you and your partners would not need to rely upon capitalization of income
     or other valuation methods to estimate the fair market value of your
     partnership's assets. Instead, such assets would be valued through
     negotiations with prospective purchasers. However, a liquidating sale of
     your partnership's property would be a taxable event for you and your
     partners and could result in significant amounts of taxable income to you
     and your partners. Under your partnership's agreement of limited
     partnership, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of the
     limited partners holding at least a majority of the units of your
     partnership. In the absence of such consent, your only option for
     liquidation of your investment would be to sell your units in a private
     transaction. Any such sale could be at a very substantial discount from
     your pro rata share of the fair market value of your partnership's property
     and might involve significant expense and delay.
 
          Continuation of Your Partnership Without the Offer. A second
     alternative would be for your partnership to continue its business without
     our offer. A number of advantages could result from the continued operation
     of your partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership may require funding from its partners. Continuation of its
     operations may be dependent on additional funding from partners or from
     other sources. Your partnership faces maturity or balloon payment dates on
     its mortgage loans and must either obtain refinancing or sell its property.
     If your partnership were to continue operating as presently structured, it
     could be forced to borrow on terms that could result in net losses from
     operations. In addition, continuation of your
 
                                      S-12
<PAGE>   5014
 
     partnership without the offer would deny you and your partners the benefits
     that your general partner expects to result from the offer. For example, a
     partner of your partnership would have no opportunity for liquidity unless
     he were to sell his units in a private transaction. Any such sale would
     likely be at a very substantial discount from the partner's pro rata share
     of the fair market value of your partnership's property.
 
  Expected Benefits of the Offer
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership for cash
or for units in the AIMCO Operating Partnership.
 
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units and receive, at our
       option, shares of AIMCO's Class I Preferred Stock, shares of AIMCO's
       Class A Common Stock or cash. AIMCO's Class A Common Stock is, and
       AIMCO's Class I Preferred Stock is expected to be, listed and traded on
       the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. However, one class of outstanding Partnership Preferred Units
       has prior distribution rights and the Tax-Deferral      % Preferred OP
       Units rank equal to six other outstanding classes of Partnership
       Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units and receive, at our option,
       shares of AIMCO's Class A Common Stock (on a one-for-one basis, subject
       to adjustment in certain circumstances) or an equivalent amount of cash.
       AIMCO's Class A Common Stock is listed and traded on the New York Stock
       Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis).
 
     - Growth Potential. Our assets, organizational structure and access to
       capital enables us to pursue acquisition and development opportunities
       that are not available to your partnership. You would have the
       opportunity to participate in the growth of our enterprise and would
       benefit from any future increase in the AIMCO stock price and from any
       future increase in distributions on the Tax-Deferral Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

<PAGE>   5016
 
     - terminate the offer and not accept for payment any units not theretofore
       accepted for payment or paid for;
 
     - upon the failure to satisfy any of the conditions to the offer, delay the

       or paid for; and
 
     - amend the offer in any respect (subject to applicable rules regarding
       tender offers), including the nature and form of consideration.
 
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
 
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
 
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
 
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware of any jurisdiction in which the making
of the offer is not in compliance with applicable law. If we become aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, we will make a good faith effort to comply with any such law.
 
     Fees and Expenses. We will not pay any fees or commissions to any broker,
dealer or other person for soliciting tenders of units pursuant to the offer. We
will pay the Information Agent reasonable and customary compensation for its
services in connection with the offer, plus reimbursement for out-of-pocket
expenses. We will indemnify the Information Agent against certain liabilities
and expenses in connection therewith, including liabilities under the Federal
securities laws. We will pay all costs and expenses of printing and mailing this
Prospectus Supplement and the legal fees and expenses in connection therewith.
We will also pay the fees of Stanger for providing the fairness opinions for the
offer. We estimate that our total costs and expenses in making the offer
(excluding the purchase price of the units payable to you and your partners)
will be approximately $               .
 
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
     You will generally not recognize any immediate taxable gain or loss for
Federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for Federal income tax purposes on units you sell for cash. The
exchange of your units for cash and OP Units will be treated, for Federal income
tax purposes, as a partial sale of such units for cash and as a partial tax-free
contribution of such units to our operating partnership.
 
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY

     BE RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR
TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED
TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" IN

CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO
YOU OF THE OFFER.
 
VALUATION OF UNITS
 
     We determined the offer consideration by estimating the proceeds that you
would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely-
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our offer consideration. We determined our offer consideration as
follows:

FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer consideration. Stanger is not affiliated
with us or your general partner. Stanger is one of the leaders in the field of
analyzing and evaluating complex real estate transactions. However, we provided
much of the information used by Stanger in forming its fairness opinion. We
believe the information provided to Stanger is accurate in all material
respects. You should make your decision whether to tender based upon a number of
factors, including your financial needs, other financial opportunities available
to you and your tax position.
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, your
general partner considered numerous factors. In evaluating these factors, your
general partner did not quantify or otherwise attach particular weight to any of
them.
 
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we may own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
 
     Comparison of Offer Consideration to Other Values. In evaluating the offer,
your general partner has compared our cash offer consideration to:
 
     -  prices at which the units have been sold in the illiquid secondary
        market, where information concerning such transactions is known to the
        general partner; and
 
     -  your general partner's estimate of the net proceeds that would be
        distributed to you and your partners if your partnership was liquidated.

STANGER ANALYSIS
 
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer consideration from a financial point of
view. The full text of the opinion, which contains a description of the
assumptions and qualifications made, matters considered and limitations on the
review and analysis, is set forth in Appendix A-1 and should be read in its
entirety. We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. We have agreed to indemnify Stanger against
certain liabilities arising out of its engagement to render the fairness
opinion. Based on its analysis, and subject to the assumptions, limitations and
qualifications cited in its opinion, Stanger concluded that our offer
consideration is fair to you from a financial point of view.
 
COMPARISON OF YOUR PARTNERSHIP AND THE AIMCO OPERATING PARTNERSHIP
 
     There are a number of significant differences between your partnership and
the AIMCO Operating Partnership relating to, among other things, form of
organization, permitted investments, policies and restrictions, management
structure, compensation and fees, and investor rights. For example, the general
 
                                      S-17
<PAGE>   5019
 
partner of your partnership may be removed by the limited partners while the
limited partners of the AIMCO Operating Partnership cannot remove the general
partner. Also, your partnership is limited as to the number of limited partner
interests it may issue while the AIMCO Operating Partnership is not subject to
such limitations.
 
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
 
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. For example, unlike
the AIMCO OP Units, you have no redemption rights with respect to your units.
 
CONFLICTS OF INTEREST
 
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
 
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner of your partnership but may receive
reimbursement for expenses generated in that capacity. The property manager
received management fees of $92,000 in 1996, $144,000 in 1997 and $94,787 for
the first six months of 1998. We have no current intention of changing the fee
structure for your property manager.
 
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
 
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of us, or a significant equity interest in us.
 
     Future Exchange Offers. Although we have no current plans to conduct
further exchange offers for your units, our plans may change based on future
circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering. If the results of operations were to improve for your partnership
under our management, we might be required to pay a higher price for any future
exchange offers we may make for units of your partnership.
 
YOUR PARTNERSHIP
 
     Your Partnership and its Property. Yorktown Towers Associates is an
Illinois limited partnership which was formed on October 16, 1981 for the
purpose of owning and operating a single apartment property located in Lombard,

     Property Management. Since December 1993, your partnership's property has
been managed by an entity which is now our affiliate. Pursuant to the management
agreement between the property manager and your partnership, the property
manager operates your partnership's property, establishes rental policies and
rates and directs marketing activities. The property manager also is responsible
for maintenance, the purchase of equipment and supplies, and the selection and
engagement of all vendors, suppliers and independent contractors. The property
manager is affiliated with us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership's agreement of limited partnership, your partnership is not
permitted to raise new equity and reinvest cash in new properties. Your
partnership will terminate on December 31, 2050, unless earlier dissolved. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period. An
investment in your partnership is a finite life investment in which partners
receive regular cash distributions out of your partnership's distributable cash
flow, if any, and upon liquidation.
 
     Borrowing Policies. Your partnership's agreement of limited partnership
allows your partnership to incur debt. As of June 30, 1998, your partnership had
a current mortgage note outstanding of $12,650,000, payable to LP Commercial
Conduit Mfg. Trust, which bears interest at a rate of 9.84%. The mortgage debt
is due in October 2001. Your partnership's agreement of limited partnership also
allows your general partner to lend funds to your partnership. Currently, the
general partner of your partnership has no loan outstanding to your partnership.
 
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
 
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 Common OP Units, respectively. On such
     date, AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
 
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
 
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
 
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
 
(e)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO", when considered with the financial data
     determined in accordance with GAAP, provides a useful measure of
     performance. However, FFO does not represent cash flow and is not
     necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO
     consistent with the NAREIT definition, plus amortization of management
     company goodwill, the non-cash deferred portion of the income tax provision
     for unconsolidated subsidiaries and less the payments of dividends on
     perpetual preferred stock. AIMCO Properties, L.P. management believes that
     presentation of FFO provides investors with industry-accepted measurements
     which help facilitate an understanding of its ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO Properties, L.P.'s basis of computing
     FFO is comparable with that of other REITs.
 
     The following is a reconciliation of net income to funds from operations:

     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
 
(b)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
 
(c)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per Common OP Unit for the six months ended
     June 30, 1998 and $1.85 per Common OP Unit for the year ended December 31,
     1997, on outstanding Common OP Units, (ii) estimated distributions to be
     paid based on the rate of $3.5625 per unit for the six months ended June
     30, 1998 and $7.125 per unit for the year ended December 31, 1997 on
     outstanding Class B Partnership Preferred Units, (iii) estimated
     distributions to be paid based on the rate of $1.125 per unit for the six
     months ended June 30, 1998 and $2.25 per unit for the year ended December
     31, 1997 on outstanding Class C Partnership Preferred Units, (iv) estimated
     distributions to be paid based on the rate of $1.095 per unit for the six
     months ended June 30, 1998 and $2.19 per unit for the year ended December
     31, 1997 on outstanding Class D Partnership Preferred Units, (v) estimated
     distributions to be paid based on the rate of $1.1718 per unit for the six
     months ended June 30, 1998 and $2.34375 per unit for the year ended
     December 31, 1997 on outstanding Class G Partnership Preferred Units, and
     (vi) estimated distributions to be paid based on the rate of $1.1875 per
     unit for the six months ended June 30, 1998 and $2.375 per unit for the
     year ended December 31, 1997 on outstanding Class H Partnership Preferred
     Units.
 
(d)  AIMCO Properties, L.P.'s management believes that the presentation of funds
     from operations or "FFO," when considered with the financial data
     determined in accordance with GAAP, provides useful measures of AIMCO
     Properties, L.P. performance. However, FFO does not represent cash flow and
     is not necessarily indicative of cash flow or liquidity available to AIMCO
     Properties, L.P., nor should it be considered as an alternative to net
     income as an indicator of operating performance. The Board of Governors of
     NAREIT defines FFO as net income (loss), computed in accordance with GAAP,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of Apartment Investment and Management
Company or "AIMCO." AIMCO is a real estate investment trust that owns and
manages multifamily apartment properties throughout the United States. Based on
apartment unit data compiled as of January 1, 1998 by the National Multi Housing
Council, we believe that, as of October 1, 1998, AIMCO was the largest owner and
manager of multifamily apartment properties in the United States, with a total
portfolio of 396,090 apartment units in 2,303 properties located in 49 states,
the District of Columbia and Puerto Rico. As of October 1, 1998, AIMCO:
 
     - owned or controlled 58,495 units in 209 apartment properties;
 
     - held an equity interest in 239,879 units in 1,335 apartment properties;
       and
 
     - managed 97,716 units in 759 apartment properties for third party owners
       and affiliates.
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                                  RISK FACTORS
 
RISKS TO UNITHOLDERS WHO TENDER THEIR UNITS IN THE OFFER
 
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base our valuation of the your
partnership's property on any third-party appraisal or valuation. We established
the terms of our offer, including the exchange ratios and the cash
consideration. Such terms are not the result of arms-length negotiations. It is
uncertain whether our offer consideration reflects the value which would be
realized upon a sale of your units or a liquidation of your partnership's
assets. Because of our affiliation with your general partner, your general
partner makes no recommendation to you as to whether you should tender your
units. We have retained Stanger to conduct an analysis of our offer and to
render an opinion as to the fairness to you of our offer consideration from a
financial point of view.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's property may outperform our larger, more diversified portfolio of
assets. Although we cannot predict the future value of your partnership's
property, our offer consideration could be less than the net proceeds that you
would realize upon a future liquidation of your partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your units and, instead, continue to hold your units and
ultimately receive proceeds from a liquidation of your partnership. However, you
may prefer to receive our offer consideration now rather than wait for uncertain
future net liquidation proceeds. Furthermore, your general partner has no
present intention to liquidate your partnership, and your partnership's
agreement of limited partnership does not require a sale of your partnership's
property by any particular date.
 
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
our offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price.
 
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is a
subsidiary of AIMCO and an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to our offer.
These conflicts include the fact that a decision of the limited partners of your
partnership to remove, for any reason, your general partner or the manager of
your partnership's property from its current position would result in a decrease
or elimination of the substantial fees paid to your general partner or the
property manager for services provided to your partnership. Your general partner
makes no recommendation to you as to whether you should tender your units. Such
conflicts of interest in connection with our offer and our operation's differ
from those conflicts of interest that currently exist for your partnership.
 
                                      S-26
<PAGE>   5028
 
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. If you tender your
units in response to our offer, you will transfer all rights title and interest
in and to all of the units that we accept, and all distributions in respect of
such units on or after the date on which we accept such units solely for
purchase. Accordingly, following the purchase of your units, we would be
entitled to receive any future distributions from the operations of your
partnership to the extent of the units we acquire. Similarly, if you tender your
units for OP Units, you will be entitled to future distributions from the
operations of the AIMCO Operating Partnership.
 
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, your exchange of units for
OP Units will not be a taxable transaction. Your sale of units for cash will be
a taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the sale and your adjusted tax
basis in the units you transfer to us. Your exchange of units for cash and OP
Units will be treated, for Federal income tax purposes, as a partial taxable
sale of such units for cash and as a partial tax-free contribution of such units
to the AIMCO Operating Partnership. If you exchange your units for cash or for
cash and OP Units, the "amount realized" will be measured by the sum of the cash
you receive plus the portion of your partnership's liabilities allocated to the
units sold for Federal income tax purposes. To the extent that the amount of
cash received plus the allocable share of your partnership's liabilities exceeds
your tax basis in the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell your
partnership's property or prepay the current mortgage on your partnership's
property within any specified time period, any such action in the future
generally will require you to fully recognize any deferred taxable gain if you
exchange your units for OP Units. In addition, if the AIMCO Operating
Partnership were to be treated as a "publicly traded partnership" for Federal
income tax purposes, passive activity losses generated by other passive activity
investments held by you, including passive activity loss carryovers attributable
to your units, could not be used to offset your allocable share of income
generated by the AIMCO Operating Partnership. See "Certain Federal Income Tax
Matters." If you redeem OP Units for shares of AIMCO Class A Common Stock or
Preferred Stock, you will recognize gain or loss measured by the difference
between the amount realized from our tender offer and your adjusted tax basis in
the OP Units exchanged. In addition, if you acquire shares of AIMCO stock, you
will no longer be able to use income and loss from your investment to offset
"passive" income and losses from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
 
     This summary is a general discussion of certain of the anticipated Federal
income tax consequences of the offer. This summary does not discuss all aspects
of Federal income taxation that may be relevant to you in light of your specific
circumstances or if you are subject to special treatment under the Code. The
particular tax consequences for you of our offer will depend upon a number of
factors related to your tax situation, including your tax basis in your units,
whether you dispose of all of your units in your partnership (and therefore are
no longer subject to the "passive" loss rules with respect to your partnership).
Because the income tax consequences of tendering units will not be the same for
everyone, you should consult your own tax advisor with specific reference to
your own tax situation.
 
RISKS TO UNITHOLDERS EXCHANGING UNITS FOR OP UNITS IN THE OFFER
 
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you exchange your
units for OP Units, you will have changed fundamentally the nature of your
investment. Your partnership owns and manages a single apartment property. In
contrast, the AIMCO Operating Partnership is in the business of acquiring,
marketing, managing and operating a large portfolio of apartment properties.
While diversification of assets may reduce certain risks of investment
attributable to a single property or entity, there can be no assurance as to the
value or performance of our securities or our portfolio of properties as
compared to the value of your units or your partnership. Proceeds of future
asset sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
 
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been
fluctuations in the trading prices for many REIT securities. There may be
subsequent changes in public market valuations of real estate assets relative to
private market valuations of real estate assets. We cannot predict the price at
which the Class I
 
                                      S-27

Preferred Stock or the Class A Common Stock will trade following the time at
which Preferred OP Units or Common OP Units may be redeemed for shares of Class
I Preferred Stock or Class A Common Stock. Furthermore, the liquidity of the
Class I Preferred Stock and the Class A Common Stock at the time at which OP
Units may be redeemed is also uncertain.
 
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of your partnership.
 
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by your partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
 
RISKS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS IN THE OFFER
 
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for your units, nor is there another reliable standard for
determining the fair market value of your units. If you desire or need
liquidity, you may wish to consider our offer. Our offer affords you an
opportunity to dispose of your units for cash, an opportunity which might not be
available to you in the foreseeable future. However, our offer consideration
does not necessarily reflect the price that you would receive in an open market
for your units or upon a liquidation of your partnership's assets. Such prices
may be higher or lower than our offer consideration.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $       , current annualized distributions with
respect to the Common OP Units are $2.25, and distributions are with respect to
your units for the six months ended June 30, 1998 were $3,543.69 (equivalent to
$7087.38 on an annualized basis). This is equivalent to distributions of
$          per year on the number of Tax-Deferral      % Preferred OP Units, or
distributions of $          per year on the number of Tax-Deferral Common OP
Units, that you would receive in an exchange for each of your partnership's
units. Therefore, distributions with respect to the Preferred OP Units and
Common OP Units that we are offering are expected to be        , immediately
following our offer, than the distributions with respect to your units. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
     FUTURE CONTROL BY AIMCO. Because your general partner is a subsidiary of
AIMCO, we control the management of your partnership. In addition, if we acquire
more units, we will increase our ability to influence voting decisions with
respect to your partnership. Furthermore, in the event that we acquire a
substantial number of units pursuant to our offer, removal of your general
partner without our consent may become more difficult or impossible. We also own
the company that manages your partnership's property. In the event that we
acquire a substantial number of units pursuant to our offer, removal of the
property manager without our consent may become more difficult or impossible.
 
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of your
partnership's liabilities is treated, for Federal income tax purposes, as a
deemed cash distribution. Although your general partner has no current plan or
intention to reduce the liabilities of your partnership, it is possible that
future economic, market, legal, tax or other considerations may cause your
general partner to reduce the liabilities of your partnership. If the
liabilities of your partnership were to be reduced, and you do not tender all of
your units pursuant to our offer, you will be treated as receiving a
hypothetical distribution of cash resulting from a decrease in your share of the
liabilities of your partnership. Any such hypothetical distribution of cash
would be treated as a nontaxable return of capital to the extent of your
adjusted tax basis in your units and thereafter as gain.
 
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership's
agreement of limited partnership restricts you from making any transfer that
would cause 50% or more of the total interest in your partnership to be
transferred within a 12-month period. If we acquire a significant interest in
your partnership, through this offer, you may not be able to transfer your units
for the 12-month period after our offer.

     MOODY'S REVISION OF AIMCO'S OUTLOOK OF RATINGS TO NEGATIVE. On October 1,
1998, Moody's Investors Service revised its outlook for the ratings of AIMCO
from stable to negative to reflect its concerns surrounding AIMCO's ability to
successfully implement its financial strategy while maintaining a prudent
capital structure as a result of the more difficult general capital market
conditions. Moody's noted that AIMCO's access to the public markets may prove
challenging in light of the volatility in both the equity and capital markets
for REITs. Moody's assigned a "ba3" rating to the Class I Preferred Stock
proposed to be issued by AIMCO, and confirmed its previous ratings related to
AIMCO's preferred stock and debt in its shelf registration statement. Moody's
indicated that its rating action continues to reflect AIMCO's increasing
leveraged profile, including high levels of secured debt and preferred stock,
limited financial flexibility and integration risks resulting from the merger
with Insignia. Moody's also noted AIMCO's high level of encumbered properties
and material investments in loans to highly leveraged partnerships in which
AIMCO owns a general partnership interest. At the same time, Moody's confirmed
its existing rating on AIMCO's existing preferred stock and senior debt.
 
                      BACKGROUND AND REASONS FOR THE OFFER
 
BACKGROUND OF THE OFFER
 
  General
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to retain or liquidate your investment in your partnership by
tendering for OP Units or for cash.
 
     On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired the general partner of your partnership and the manager of your
partnership's property.
 
     We currently do not own any limited partnership interest in your
partnership.
 
  Engagement of Fairness Opinion Provider
 
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for our offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion for your
partnership and other partnerships.
 
ALTERNATIVES CONSIDERED
 
     One of the reasons AIMCO acquired Insignia was that AIMCO expected to make
offers to acquire limited partnership interests of some of the limited
partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). Such offers would provide liquidity for the limited partners of
the Insignia Partnerships. Such offers would also allow the AIMCO Operating
Partnership an opportunity to increase its ownership interest in certain
Insignia Partnerships which would provide a larger asset and capital base and
increased diversification.
 
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by the general partner of
your partnership.
 
  Liquidation
 
     Benefits of Liquidation. One alternative would be for your partnership to
sell its assets, distribute the net liquidation proceeds to its partners in
accordance with your partnership's agreement of limited partnership, and
thereafter dissolve. Partners would be at liberty to use the net liquidation
proceeds after taxes for
 
                                      S-29
<PAGE>   5031
 
investment, business, personal or other purposes, at their option. If your
partnership were to sell its assets and liquidate, you and your partners would
not need to rely upon capitalization of income or other valuation methods to
estimate the fair market value of your partnership's assets. Instead, such
assets would be valued through negotiations with prospective purchasers (in many
cases unrelated third parties).
 
     Disadvantages of Liquidation. A liquidating sale of part or all of your
partnership's property would be a taxable event for you and your partners and
could result in significant amounts of taxable income to you and your partners.
In the opinion of the general partner of your partnership, the present time may
not be the most desirable time to sell the real estate assets of your
partnership in private transactions, and any liquidation sale would be
uncertain. Liquidation of the partnership's assets may trigger a substantial
prepayment penalty under the mortgage for the property. Your general partner
believes it currently is in the best interest of your partnership to continue
holding its real estate assets. Finally, under your partnership's agreement of
limited partnership, a sale of your partnership's assets and the subsequent
liquidation of your partnership could occur only with the consent of the limited
partners holding at least a majority of the units of your partnership. In the
absence of such consent, your only option for liquidation would be to sell your
units in a private transaction. Any such sale likely would be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property and might involve significant expense and delay.
 
  Continuation of the Partnership Without the Offer
 
     Benefits of Continuation. A second alternative would be for your
partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing agreement of limited
partnership, without our offer. A number of advantages would result from the
continued operation of your partnership. Given improving rental market
conditions, the level of distributions might increase over time. It is possible
that the private resale market for apartment properties could improve over time,
making a sale of the partnership's property in a private transaction at some
point in the future a more attractive option than it is currently.
 
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of your partnership without our
offer. Your partnership may require funding from its partners. Continuation of
its operations may be dependent on additional funding from partners and from
other sources. Your partnership faces maturity or balloon payment dates on its
mortgage loans and must either obtain refinancing or sell its property. If your
partnership were to continue operating as presently structured, your partnership
could be forced to borrow on terms that could result in net losses from
operations.
 
     In addition, continuation of your partnership as a separate entity without
our offer would deny you and your partners the benefits of our offer. For
example, you would have no opportunity for liquidity unless you were to sell
your units in a private transaction. Any such sale would likely be at a very
substantial discount from your pro rata share of the fair market value of your
partnership's property. Continuation without our offer would deny you and your
partners the benefits of diversification into a company which has a much larger
and more diverse portfolio of apartment properties. Also, there are currently no
distributions paid on your units while there are expected to be regular,
quarterly distributions on OP Units.
 
EXPECTED BENEFITS OF THE OFFER
 
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in the
property owned by your partnership while providing you and other investors with
an opportunity to retain or liquidate your investment or to invest in the AIMCO
Operating Partnership.
 
     There are four principal advantages of tendering your units for Preferred
OP Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units and receive, at our option, shares of
       AIMCO's Class I Preferred Stock, shares of AIMCO's Class A Common Stock
       or cash. AIMCO's Class A Common Stock is, and AIMCO's Class I Preferred
       Stock is expected to be, listed and traded on the New York Stock
       Exchange.
 
                                      S-30
<PAGE>   5032
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. However, one class
       of outstanding Partnership Preferred Units has prior distribution rights
       and the Tax-Deferral      % Preferred OP Units rank equal to six other
       outstanding classes of Partnership Preferred Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     There are five principal advantages of tendering your units for Common OP
Units:
 
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units and receive, at our option, shares of AIMCO's
       Class A Common Stock (on a one-for-one basis, subject to adjustment in
       certain circumstances) or an equivalent amount of cash. AIMCO's Class A
       Common Stock is listed and traded on the New York Stock Exchange.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Common OP Units.
 
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Historically, the quarterly distributions paid on the Common OP
       Units have been equivalent to the dividends paid on AIMCO's Class A
       Common Stock. We expect this to continue in the future.
 
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
 
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
 
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for Federal income tax purposes.

                                   THE OFFER
 
TERMS OF THE OFFER; EXPIRATION DATE
 
     We are offering to acquire up to      % of the outstanding units of your
partnership for consideration per unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender units pursuant
to our offer, you may chose to receive any of such forms of consideration for
your units or any combination of such forms of consideration.
 
     Upon the terms and subject to the conditions of our offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) units that
are validly tendered prior to the expiration of the offer and not withdrawn in
accordance with the procedures set forth in "-- Withdrawal Rights." Our offer
will expire at 5:00 p.m., Denver, Colorado time, on                  , 1998,
unless the AIMCO Operating Partnership in its sole discretion, extends the
offer. See "-- Extension of Tender Period; Termination; Amendment" for a
description of the AIMCO Operating Partnership's right to extend the period of
time during which the offer is open and to amend or terminate the offer.
 
     If, prior to the expiration of the offer, the AIMCO Operating Partnership
increases the offer consideration, everyone whose units are accepted in the
offer will receive the increased consideration, regardless of whether their
units were tendered before or after the increase in the offer consideration.
 
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the offer, accept for payment and pay for all units validly
tendered and not withdrawn prior to the expiration of our offer (subject to
proration as described below), with appropriate adjustments to avoid purchases
that would violate the AIMCO Operating Partnership's agreement of limited
partnership and any relevant procedures or regulations promulgated by the AIMCO
Operating Partnership's general partner.
 
     Our offer is conditioned on the satisfaction of certain conditions. Our
offer is not conditioned upon any minimum amount of units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of our offer.
The AIMCO Operating Partnership reserves the right (but is not obligated), in
its sole discretion, to waive any or all of those conditions. If, on or prior to
the expiration of the offer, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units, (ii) waive all the unsatisfied conditions and purchase all
units validly tendered, (iii) extend the offer and, subject to the right of
unitholders to withdraw units until the expiration of the offer, retain the
units that have been tendered during the period or periods for which the offer
is extended, and (iv) amend the offer.
 
     For administrative purposes, the transfer of units tendered pursuant to our
offer will be deemed to take effect as of             , 1998 (subject to
proration as described below).
 
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all units (subject to proration as described below) which are validly tendered
and not withdrawn prior to the expiration of the offer as promptly as
practicable following the expiration of the offer. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered units prior to the expiration of the offer. A beneficial owner of units
whose units are owned of record by an individual retirement account or other
qualified plan will not receive direct payment of the offer consideration.
Instead, payment will be made to the custodian of such account or plan. In all
cases, payment for units purchased pursuant to the offer will be made only after
timely receipt by the Information Agent of a properly completed and duly
executed Letter of Transmittal and any other documents required by the Letter of
Transmittal. The offer consideration shall be reduced by any interim
distributions made by your partnership between                  and the
expiration of the offer. See "Procedure for Tendering Units." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER CONSIDERATION BY REASON OF ANY
DELAY IN MAKING SUCH PAYMENT.
 
                                      S-32
<PAGE>   5034
 
     For purposes of the offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the offer, and thereby purchased,
validly tendered units if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of its acceptance of those
units for payment pursuant to the offer. Payment for units accepted for payment
pursuant to the offer will be made through the Information Agent, which will act
as agent for tendering unitholders for the purpose of receiving cash payments
from the AIMCO Operating Partnership and transmitting cash payments to tendering
unitholders. OP Units will be issued directly by the AIMCO Operating Partnership
to those unitholders who elect to receive OP Units pursuant to the offer.
 
     If any tendered units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any units tendered pursuant to the offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for units tendered pursuant to the offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered units, and those units may not be
withdrawn except to the extent that the tendering offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay the
offer consideration in respect of units tendered or return those units promptly
after termination or withdrawal of the offer.
 
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of its affiliates, the right to purchase
units tendered pursuant to the offer, but no such transfer or assignment will
relieve the AIMCO Operating Partnership of its obligations under the offer or
prejudice your right to receive payment for units validly tendered and accepted
for payment pursuant to the offer. Specifically, we may assign our rights to
purchase your units for which you elect to receive cash to Insignia Properties
Trust ("IPT") or Insignia Properties, L.P. ("IPLP"). IPT is a Maryland business
trust which operates as a REIT in the same line of business as us. As a result
of the merger with Insignia Financial Group, Inc. into AIMCO on October 1, 1998,
AIMCO acquired approximately 51% of the outstanding common stock of IPT. On
October 3, 1998, IPT and AIMCO entered into an agreement, subject to shareholder
approval, to merge IPT into AIMCO. IPLP is a Delaware limited partnership that
conducts substantially all of the operations of IPT.
 
PROCEDURE FOR TENDERING UNITS
 
  Valid Tender
 
     To validly tender units pursuant to the offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of this Prospectus Supplement, on or prior to the
expiration of the offer. You may tender all or any portion of your units. No
alternative, conditional or contingent tenders will be accepted.
 
  Signature Requirements
 
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.
 
     In order to participate in the offer, you must validly tender and not
withdraw your units prior to the expiration of the offer.
 
                                      S-33
<PAGE>   5035
 
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
 
  Appointment as Proxy
 
     By executing the Letter of Transmittal, you will irrevocably appoint the
AIMCO Operating Partnership and its designees as your proxies, in the manner set
forth in the Letter of Transmittal, each with full power of substitution, to the
fullest extent of your rights with respect to your units tendered and accepted
for payment by the AIMCO Operating Partnership. Each such proxy shall be
considered coupled with an interest in the tendered units. Such appointment will
be effective when, and only to the extent that, the AIMCO Operating Partnership
accepts the tendered units for payment. Upon such acceptance for payment, all
prior proxies given by you with respect to such units will, without further
action, be revoked, and no subsequent proxies may be given (and if given will
not be effective). The AIMCO Operating Partnership and the designees of the
AIMCO Operating Partnership will, as to those units, be empowered to exercise
all of your voting and other rights as they, in their sole discretion, may deem
proper at any meeting of unitholders, by written consent or otherwise. The AIMCO
Operating Partnership reserves the right to require that, in order for units to
be deemed validly tendered, immediately upon the AIMCO Operating Partnership's
acceptance for payment for the units, the AIMCO Operating Partnership must be
able to exercise full voting rights with respect to the units, including voting
at any meeting of unitholders then scheduled or acting by written consent
without a meeting. By executing the Letter of Transmittal, you agree to execute
all such documents and take such other actions as shall be reasonably required
to enable the units tendered to be voted in accordance with the directions of
the AIMCO Operating Partnership. The proxy and power of attorney granted to the
AIMCO Operating Partnership upon your execution of the Letter of Transmittal
will remain effective and be irrevocable for a period of ten years following the
termination of the offer.
 
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
 
     If you tender units, you will agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all of your right, title and interest in and to such units tendered that are
accepted for payment pursuant to the offer, including, without limitation, (i)
all of your interest in the capital of your partnership, and interest in all
profits, losses and distributions of any kind to which you shall at any time be
entitled in respect of the units; (ii) all other payments, if any, due or to
become due to you in respect of the units, under or arising out of your
partnership's agreement of limited partnership, whether as contractual
obligations, damages, insurance proceeds, condemnation awards or otherwise;
(iii) all of your claims, rights, powers, privileges, authority, options,
security interests, liens and remedies, if any, under or arising out of your
partnership's agreement of limited partnership or your ownership of the units,
including, without limitation, all voting rights, rights of first offer, first
refusal or similar rights, and rights to be substituted as a limited partner of
your partnership; and (iv) all of your present and future claims, if any,
against your partnership or your partners under or arising out of your
partnership's agreement of limited partnership for monies loaned or advanced,
for services rendered, for the management of your partnership or otherwise.
 
  Election of Consideration
 
     You may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to our offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that you tender units but do not indicate on the
Letter of Transmittal which type of consideration you want, the AIMCO Operating
Partnership will issue Preferred OP Units to you.
 
                                      S-34
<PAGE>   5036
 
  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of units pursuant to the offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular unit determined by it not to be in proper form or if the
acceptance of or payment for that unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
offer that it is legally permitted to waive as to the tender of any particular
unit and to waive any defect or irregularity in any tender with respect to any
particular unit. The AIMCO Operating Partnership's interpretation of the terms
and conditions of the offer (including the Letters of Transmittal) will be final
and binding on all parties. No tender of units will be deemed to have been
validly made unless and until all defects and irregularities have been cured or
waived. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in the tender of any units or will incur any liability for
failure to give any such notification.
 
  Backup Federal Income Tax Withholding
 
     To prevent the possible application of back-up Federal income tax
withholding of 31% with respect to payment of the offer consideration, you must
provide the AIMCO Operating Partnership with your correct taxpayer
identification number. See the instructions to the Letter of Transmittal and
"Certain Federal Income Tax Matters."
 
  FIRPTA Withholding
 
     To prevent the withholding of Federal income tax in an amount equal to 10%
of the amount realized pursuant to the offer, you must certify under penalty of
perjury that you are not a foreign person. See the instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
 
  Binding Agreement
 
     If you tender units pursuant to any of the procedures described above, the
acceptance for payment of such units will constitute a binding agreement between
you and the AIMCO Operating Partnership on the terms set forth in this
Prospectus Supplement.
 
WITHDRAWAL RIGHTS
 
     Tenders of units pursuant to the offer may be withdrawn at any time prior
to the expiration of our offer, as provided in this Prospectus Supplement.
 
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of units to be withdrawn and the
name of the registered holder of such units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
 
     If purchase of, or payment for, units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the offer, tendered units may be retained by the Information Agent and may
not be withdrawn, except to the extent that participants are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay the offer consideration in respect of units tendered or return those units
promptly after termination or withdrawal of the offer.

<PAGE>   5037
 
     Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the offer.
 
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
 
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the offer is open and thereby delay acceptance for payment of, and
for, any units, (ii) to terminate the offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "-- Conditions of the Offer," to delay the
acceptance for payment of, or for, any units not already accepted for payment or
paid for and (iv) to amend the offer in any respect (including, without
limitation, increasing or decreasing the number of Preferred OP Units or Common
OP Units, or the amount of cash, offered, eliminating any of the alternative
types of consideration being offered, or increasing or decreasing the percentage
of outstanding units being sought). Notice of any such extension, termination or
amendment will promptly be disseminated in a manner reasonably designed to
inform unitholders of such change. In the case of an extension of the offer, the
extension will be followed by a press release or public announcement which will
be issued no later than 9:00 a.m., Denver, Colorado time, on the next business
day after the scheduled expiration date of the offer, in accordance with Rule
14e-1(d) under the Exchange Act.
 
     If the AIMCO Operating Partnership extends the offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
units) is delayed in its payment for units or is unable to pay for units
pursuant to the offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the offer, the Information Agent may retain
tendered units and those units may not be withdrawn except to the extent
participants are entitled to withdrawal rights as described in "-- Withdrawal
Rights;" subject, however, to the AIMCO Operating Partnership's obligation,
pursuant to Rule 14e-1(c), under the Exchange Act, to pay the offer
consideration in respect of units tendered or return those units promptly after
termination or withdrawal of the offer.
 
     If the AIMCO Operating Partnership makes a material change in the terms of
the offer, or if it waives a material condition to the offer, the AIMCO
Operating Partnership will extend the offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the offer must remain open following any material
change in the terms of the offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to participants.
Accordingly, if prior to the expiration of the offer, the AIMCO Operating
Partnership increases (other than increases of not more than two percent of the
outstanding units) or decreases the number of units being sought, or increases
or decreases the consideration offered pursuant to the offer, and if the offer
is scheduled to expire at any time earlier than the tenth business day from the
date that notice of such increase or decrease is first published, sent or given
to unitholders, the offer will be extended at least until the expiration of such
ten business days. As used herein, "business day" means any day other than a
Saturday, Sunday or a Federal holiday, and consists of the time period from
12:01 a.m. through 12:00 midnight, Denver, Colorado time.

PRORATION
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer does not exceed   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will purchase all such units so tendered and not withdrawn.
 
     If the number of units properly tendered and not withdrawn prior to the
expiration of the offer exceeds   % of the outstanding units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the
offer, will accept for purchase units in the following order of priority:
 
        (1) First, all units properly tendered and not withdrawn prior to the
     expiration of the offer by any person holding one or fewer units who
     tenders all of his or her units; and
 
        (2) Second, all other units properly tendered and not withdrawn prior to
     the expiration of the offer on a pro rata basis, with adjustments to avoid
     resulting ownership of less than one unit by a tendering offeree.
 
     Following the expiration of the offer, the AIMCO Operating Partnership may
renew the offer one or more times on the same terms as described in this
Prospectus Supplement. If the number of units properly tendered and not
withdrawn prior to the expiration of any such renewal (together with units
previously purchased in the offer) is                or less, the AIMCO
Operating Partnership will purchase such units so tendered and not withdrawn. If
the number of units in your partnership properly tendered and not withdrawn
prior to the expiration of any such renewal (together with any units previously
purchased in this offer) is greater than                , the AIMCO Operating
Partnership will purchase units in the order of priority described in the
preceding paragraph.
 
     In the event that proration of tendered units is required, the AIMCO
Operating Partnership will determine the final proration factor as promptly as
practicable after the expiration of the offer or any renewal of the offer.
 
FRACTIONAL OP UNITS
 
     We will issue fractional Common OP Units or Preferred OP Units, if
necessary.
 
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
 
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of your partnership and thereby
controls the management of your partnership. In addition, AIMCO owns the company
that manages your partnership's property. The AIMCO Operating Partnership
currently intends that, upon consummation of the offer, your partnership will
continue its business and operations substantially as they are currently being
conducted. The offer is not expected to have any effect on your partnership's
financial condition or results of operations.
 
     After the completion or termination of the offer, the AIMCO Operating
Partnership and its affiliates may acquire additional units or sell units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the units purchased pursuant to this offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the units it acquires pursuant to the offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy your partnership's property, although
it has no present intention to do so. There can be no assurance, however, that
the AIMCO Operating Partnership will initiate or complete, or will cause your
partnership to initiate or complete, any subsequent transaction during any
specific time period following the expiration of the offer or at all.
 
                                      S-37
<PAGE>   5039
 
     We currently intend that, upon consummation of the offer, your partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in your partnership's structure or
business. We have no present intention to cause your partnership to sell its
property or to prepay the current mortgage within any specified time period.
 
VOTING BY THE AIMCO OPERATING PARTNERSHIP
 
     If the AIMCO Operating Partnership acquires a substantial number of units
pursuant to the offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to your partnership. Under your
partnership's agreement of limited partnership, holders of outstanding units are
entitled to take action with respect to a variety of matters, including
dissolution and most types of amendments to your partnership's agreement of
limited partnership. See "Comparison of Your Units and AIMCO OP Units -- Voting
Rights."
 
DISSENTERS' RIGHTS
 
     Neither your partnership's agreement of limited partnership, nor applicable
law provides any right for you to have your units appraised or redeemed in
connection with or as a result of the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
CONDITIONS OF THE OFFER
 
     Notwithstanding any other provisions of the offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any units

units tendered, and may terminate or amend the offer if at any time from or

     AIMCO Operating Partnership, or the AIMCO Operating Partnership shall have
     become aware of any facts relating to your partnership, its indebtedness or
     its operations which, in the sole judgment of the AIMCO Operating

     in the S&P 500 Index, the Morgan Stanley REIT Index, or the price of the

     institutions, or (viii) in the case of any of the foregoing existing at the
     time of the commencement of the offer, in the sole judgment of the AIMCO
     Operating Partnership, a material acceleration or worsening thereof; or

     Partnership or any of its affiliates to acquire or hold or to exercise full
     rights of ownership of the units including, but not limited to, the right

<PAGE>   5041
 
     that any debt of your partnership or any of its subsidiaries secured by any
     of its or their assets is in default or has been accelerated; or
 
        (f) a tender or exchange offer for any units shall have been commenced

Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
 
EFFECTS OF THE OFFER
 
  Future Control by AIMCO
 
     Because the general partner of your partnership is a subsidiary of AIMCO,
AIMCO has control over the management of your partnership. If the AIMCO
Operating Partnership acquires units in the offer, AIMCO will increase its
ability to influence voting decisions with respect to your partnership.
Furthermore, in the event that the AIMCO Operating Partnership acquires a
substantial number of units pursuant to the offer, removal of the general
partner of your partnership (which general partner is controlled by AIMCO)
without AIMCO's consent may become more difficult or impossible. AIMCO also owns
the company that manages your partnership's property. In the event that the
AIMCO Operating Partnership acquires a substantial number of units pursuant to
the offer, removal of the property manager may become more difficult or
impossible.
 
  Distributions to the AIMCO Operating Partnership
 
     As a result of the offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of your partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in your
partnership, including the units purchased pursuant to this offer.
 
  Partnership Business
 
     This offer will not affect the operation of your partnership's property.
The AIMCO Operating Partnership will continue to control the general partner of
your partnership and the property manager will remain the same.
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of your
partnership, aware of any licenses or regulatory permits
                                      S-40
<PAGE>   5042
     that would be material to the business of your partnership, taken as a
whole, and that might be adversely affected by the AIMCO Operating Partnership's
acquisition of units as contemplated herein, or any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to the
acquisition of units by the AIMCO Operating Partnership pursuant to the offer as
contemplated herein. While there is no present intent to delay the purchase of
units tendered pursuant to the offer pending receipt of any such additional
approval or the taking of any such action, there can be no assurance that any
such additional approval or action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to your
partnership's business, or that certain parts of your partnership's business
might not have to be disposed of or other substantial conditions complied with
in order to obtain such approval or action, any of which could cause the AIMCO
Operating Partnership to elect to terminate the offer without purchasing units
hereunder. The AIMCO Operating Partnership's obligation to purchase and pay for
units is subject to certain conditions, including conditions related to the
legal matters discussed in this section.
 
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of units contemplated by this offer.
 
     Margin Requirements. The units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to this offer.
 
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the offer to be made by a licensed broker or dealer, the offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
 
FEES AND EXPENSES
 
     The AIMCO Operating Partnership will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of units pursuant to the
offer. The AIMCO Operating Partnership has retained River Oaks Partnership
Services, Inc. to act as Information Agent in connection with the offer. The
Information Agent may contact holders of units by mail, telephone, telex,
telegraph and personal interview and may request brokers, dealers and other
nominees to forward materials relating to the offer to beneficial owners of the
units. The AIMCO Operating Partnership will pay the Information Agent reasonable
and customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the Federal securities laws. The AIMCO Operating
Partnership will also pay all costs and expenses of printing and mailing this
Prospectus Supplement and the Letter of Transmittal and its legal fees and
expenses. The AIMCO Operating Partnership will also pay the fees of Stanger for
providing the fairness opinion for the offer. The AIMCO Operating Partnership
estimates that its total costs and expenses in making the offer (excluding the
purchase price of the units) will be approximately $              .
 
ACCOUNTING TREATMENT
 
     Upon consummation of the offer, the AIMCO Operating Partnership will
account for its investment in the units acquired in the offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
your partnership as a result of the offer.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
 
RANKING
 
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Class E Partnership Preferred Units,
the Common OP Units and any other interest in the AIMCO Operating Partnership if
the holders of Preferred OP Units shall be entitled to the receipt of
distributions and amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to the Class F
Partnership Preferred Units and any other interest in the AIMCO Operating
Partnership if the holders of such interest shall be entitled to the receipt of
distributions or amounts distributable upon liquidation, dissolution or winding
up in preference or priority to the holders of the Preferred OP Units ("Senior
Units"). Junior Units, Parity Units and Senior Units may be issued from time to
time by the AIMCO Operating Partnership without any approval or consent by
holders of the Preferred OP Units.
 
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
 
DISTRIBUTIONS
 
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the board of directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Unit (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % plus the annual interest rate
then applicable to U.S. Treasury notes with a maturity of five years, and (ii)
the annual dividend rate on the most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are cumulative from the date of original issue,
whether or not in any distribution period or periods such distributions have
been declared, and shall be payable quarterly on February 15, May 15, August 15
and November 15 of each year (or, if not a business day, the next succeeding
business day) (each a "Distribution Payment Date"), commencing on the first such
date occurring after the date of original issue. If the Preferred OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units will be prorated for the portion of the
quarterly period that such Preferred OP Units are outstanding on the basis of
twelve 30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
Partnership at the close of business on the February 1, May 1, August 1 or
November 1, as the case may be, immediately preceding each Distribution Payment
Date. Holders of Preferred OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any

     distribution payment or payments on the Preferred OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
 
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the AIMCO Operating Partnership with respect to any
Parity Units. Unless full cumulative distributions (including all accumulated,
accrued and unpaid distributions) on the Preferred OP Units have been declared
and paid, or declared and set apart for payment, for all past distribution
periods, no distributions (other than distributions or distributions paid in
Junior Units or options, warrants or rights to subscribe for or purchase Junior
Units) may be declared or paid or set apart for payment by the AIMCO Operating
Partnership and no other distribution of cash or other property may be declared
or made, directly or indirectly, by the AIMCO Operating Partnership with respect
to any Junior Units, nor shall any Junior Units be redeemed, purchased or
otherwise acquired (except for a redemption, purchase or other acquisition of
Common OP Units made for purposes of an employee incentive or benefit plan of
AIMCO, the AIMCO Operating Partnership or any subsidiary) for any consideration
(or any monies be paid to or made available for a sinking fund for the
redemption of any such Junior Units), directly or indirectly, by the AIMCO
Operating Partnership (except by conversion into or exchange for Junior Units,
or options, warrants or rights to subscribe for or purchase Junior Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Units. Notwithstanding the foregoing provisions of
this paragraph, the AIMCO Operating Partnership shall not be prohibited from (i)
declaring or paying or setting apart for payment any distribution on any Parity
Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Units, in
each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain AIMCO's qualification as a REIT.
 
ALLOCATION
 
     Holders of Preferred OP Units will be allocated net income of the AIMCO
Operating Partnership in an amount equal to the distributions made on such
holder's Preferred OP Units during the taxable year. Holders of Preferred OP
Units also will generally be allocated any net loss of the AIMCO Operating
Partnership that is not allocated to holders of Common OP Units or other
interests of the AIMCO Operating Partnership.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Unit (the "Stated Preference"), plus accumulated, accrued and unpaid
distributions (whether or not earned or declared) to the date of final
distribution to such holders; but such holders shall not be entitled to any
further payment. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income or gain will be made to
any holder of Junior Units upon the liquidation, dissolution or winding up of
the AIMCO Operating Partnership. If, upon any liquidation, dissolution or
winding up of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such
 
                                      S-43
<PAGE>   5045
     Parity Units ratably in the same proportion as the respective amounts that
would be payable on such Preferred OP Units and any such Parity Units if all
amounts payable thereon were paid in full. A voluntary or involuntary
liquidation, dissolution or winding up of the AIMCO Operating Partnership will
not include a consolidation or merger of the AIMCO Operating Partnership with
one or more partnerships, corporations or other entities, or a sale or transfer
of all or substantially all of the AIMCO Operating Partnership's assets. Upon
any liquidation, dissolution or winding up of the AIMCO Operating Partnership,
after all allocations shall have been made in full to the holders of Preferred
OP Units and any Parity Units to enable them to receive their Liquidation
Preference, any Junior Units shall be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Preferred OP Units
and any Parity Units shall not be entitled to share therein.
 
REDEMPTION
 
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership's agreement of limited
partnership. If shares of Class I Preferred Stock or Class A Common Stock of
AIMCO are issued in exchange for any Preferred OP Units tendered for redemption,
the Preferred OP Units that are acquired by AIMCO will be converted to a class
of AIMCO Operating Partnership units that corresponds to the class of stock so
issued.
 
VOTING RIGHTS
 
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership's agreement of limited partnership, the holders of the Preferred OP
Units will have the same voting rights as holders of the Common OP Units. See
"Description of OP Units" in the accompanying Prospectus. So long as any
Preferred OP Units are outstanding, in addition to any other vote or consent of
partners required by law or by the AIMCO Operating Partnership's agreement of
limited partnership, the affirmative vote or consent of holders of at least 50%
of the outstanding Preferred OP Units will be necessary for effecting any
amendment of any of the provisions of the Partnership Unit Designation of the
Preferred OP Units that materially and adversely affects the rights or
preferences of the holders of the Preferred OP Units. The creation or issuance
of any class or series of AIMCO Operating Partnership units, including, without
limitation, any AIMCO Operating Partnership units that may have rights senior or
superior to the Preferred OP Units, will not be deemed to materially adversely
affect the rights or preferences of the holders of Preferred OP Units. With
respect to the exercise of the above described voting rights, each Preferred OP
Unit will have one (1) vote per Preferred OP Unit.
 
RESTRICTIONS ON TRANSFER
 
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership's
agreement of limited partnership.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
 
     The Class I Preferred Stock (a) ranks prior to the Class A Common Stock and
the Class E Preferred Stock, and any other class or series of capital stock of
AIMCO if the holders of the Class I Preferred Stock are to be entitled to the
receipt of dividends or of amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class I Junior Stock"), (b) ranks on a parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, the Class H Preferred Stock and with any other class or
series of capital stock of AIMCO, if the holders of such class of stock or
series and the Class I Preferred Stock are entitled to the receipt of dividends
and of amounts distributable upon liquidation, dissolution or winding-up in
proportion to their respective amounts of accrued and unpaid dividends per share
or liquidation preferences, without preference or priority one over the other
("Class I Parity Stock") and (c) ranks junior to any class or series of capital
stock of AIMCO if the holders of such class or series are entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class I Preferred
Stock ("Class I Senior Stock").
 
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO may be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock are entitled to receive a
liquidation preference of $25 per share (the "Class I Liquidation Preference"),
plus an amount equal to all accumulated, accrued and unpaid dividends to the
date of final distribution to such holders; but such holders shall not be
entitled to any further payment. If proceeds available for distribution are
insufficient to pay the preference described above and any liquidating payments
on any other shares of any class or series of Class I Parity Stock, then such
proceeds will be distributed among the holders of Class I Preferred Stock and
any such other Class I Parity Stock ratably in the same proportion as the
respective amount that would be payable on such Class I Preferred Stock and any
such other Class I Parity Stock if all amounts payable thereon were paid in
full.
 
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and is not subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock are in arrears for six or more quarterly periods, the number of
directors constituting the AIMCO board of directors will be increased by two and
the holders of Class I Preferred Stock (voting together as a single class with
all other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the AIMCO charter in any manner that
would adversely affect the rights of the holders of Class I Preferred Stock, and
to approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
 
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO board of directors may waive such ownership limit if evidence
satisfactory to the AIMCO board of directors and AIMCO's tax counsel is
presented that such ownership will not then or
 
                                      S-45
<PAGE>   5047
 
     in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO board of directors may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. If shares of Class I Preferred Stock in
excess of the Class I Preferred Ownership Limit, or shares of Class I Preferred
Stock which would result in AIMCO being "closely held," within the meaning of
Section 856(h) of the Code, or which would otherwise result in AIMCO failing to
qualify as a REIT, are issued or transferred to any person, such issuance or
transfer will be null and void to the intended transferee, and the intended
transferee would acquire no rights to the Class I Preferred Stock. Shares of
Class I Preferred Stock transferred in excess of the Class I Preferred Ownership
Limit or other applicable limitations will automatically be transferred to a
trust for the exclusive benefit of one or more qualifying charitable
organizations to be designated by AIMCO. Shares transferred to such trust will
remain outstanding, and the trustee of the trust will have all voting and
dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Class I Preferred Ownership Limit or other applicable limitation. Upon a
sale of such shares by the trustee, the interest of the charitable beneficiary
will terminate, and the sales proceeds would be paid, first, to the original
intended transferee, to the extent of the lesser of (a) such transferee's
original purchase price (or the original market value of such shares if
purportedly acquired by gift or devise) and (b) the price received by the
trustee, and, second, any remainder to the charitable beneficiary. In addition,
shares of Class I Preferred Stock held in such trust are purchasable by AIMCO
for a 90-day period at a price equal to the lesser of the price paid for the
Class I Preferred Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Class I Preferred Stock on the date that AIMCO determines
to purchase the Class I Preferred Stock. The 90-day period commences on the date
of the violative transfer or the date that the AIMCO board of directors
determines in good faith that a violative transfer has occurred, whichever is
later. All certificates representing shares of Class I Preferred Stock bear a
legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
 
     The following summary is a general discussion of certain Federal income tax
consequences of the Offer that may be relevant to (i) persons who tender some or
all of their units in exchange for OP Units pursuant to the offer, (ii) persons
who tender some or all of their units for cash pursuant to the offer and (iii)
persons who do not tender any of their units pursuant to the offer. This
discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and your partnership are classified and subject
to taxation for Federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes). This summary assumes that your units and any OP
Units that you receive in the offer constitute capital assets (generally,
property held for investment). No advance ruling has been or will be sought from
the IRS regarding any matter discussed in this Prospectus Supplement.
 
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF
SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT TO SELL
OR EXCHANGE IN LIGHT OR YOUR SPECIFIC TAX SITUATION.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR OP UNITS
 
     Except as described below, you will not recognize gain or loss for Federal
income tax purposes upon an exchange of units solely for OP Units. You may
recognize gain upon such exchange, where, immediately prior to such exchange,
the amount of liabilities of your partnership allocable to the units transferred
by you exceeds the amount of the AIMCO Operating Partnership liabilities
allocated to the OP Units issued to you, as determined immediately after such
exchange. In such event, any such excess would be treated as a deemed
distribution to you of cash from the AIMCO Operating Partnership. Such deemed
cash distribution would be treated as a nontaxable return of capital to the
extent of your adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
 
     The AIMCO Operating Partnership anticipates that, under most circumstances,
you will be allocated an amount of the AIMCO Operating Partnership liabilities,
as determined immediately after an exchange of units pursuant to the offer, at
least equal to the amount of liabilities of your partnership that were allocable
to such units prior to such exchange. Accordingly, the AIMCO Operating
Partnership anticipates that most people would not recognize gain or loss as a
result of an exchange of units solely for OP Units pursuant to the offer.
 
     If you are considering exchanging units for OP Units pursuant to the offer,
please read the description under the heading "Certain Federal Income Tax
Considerations -- the AIMCO Operating Partnership Tax Considerations -- Tax
Consequences Upon Contribution of Property to the AIMCO Operating Partnership"
in the accompanying Prospectus.
 
TAX CONSEQUENCES OF EXCHANGING UNITS FOR CASH AND OP UNITS
 
     Generally, if you exchange your units for cash and OP Units, it will be
treated, for Federal income tax purposes, as a partial taxable sale of such
units for cash and as a partial tax-free contribution of such units to the AIMCO
Operating Partnership. The portion of the units that will be treated as sold to
the AIMCO Operating Partnership will be equal to a fraction, the numerator of
which will be the sum of the cash received by you pursuant to the offer plus the
amount of your partnership liabilities deemed transferred to you
                                      S-50
<PAGE>   5052
 
pursuant to the offer, and the denominator of which is the fair market value of
the aggregate consideration received by you pursuant to the offer (i.e., the sum
of the numerator of such fraction plus the fair market value of the OP Units
received by you pursuant to the offer). The transfer by you of the remaining
portion of such units will generally be treated as a tax-free contribution. At
the time of transfer, the adjusted tax basis of the transferred units is
allocated between the portion of the units deemed sold and the remaining portion
of the units deemed contributed on the basis of each such portion's respective
fair market value.
 
     For purposes of the partial sale rules, the amount of your partnership's
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of your partnership's liabilities allocable to you in respect of
the transferred units immediately prior to the exchange, over the AIMCO
Operating Partnership liabilities allocated to you as determined immediately
after the exchange or (ii) the product of (A) your partnership's liabilities
allocable to you in respect of such transferred units immediately prior to the
exchange and (B) a fraction, (x) the numerator of which is the cash received and
(y) the denominator of which is the excess of the fair market value of the
aggregate consideration received in the exchange over the amount of your
partnership liabilities allocable to you in respect of the transferred units
immediately prior to the exchange.
 
     To the extent that your transfer of units to the AIMCO Operating
Partnership is treated as a taxable sale, you will recognize gain or loss in an
amount equal to the difference between (i) the cash received plus the amount of
your partnership's liabilities deemed transferred in the exchange and (ii) the
adjusted tax basis allocable to the portion of such units deemed sold. Thus,
your tax liability resulting from such sale of units could exceed the amount of
cash received upon such sale. To the extent that your transfer of units in
exchange for OP Units is treated as a tax-free contribution to the AIMCO
Operating Partnership, you will generally not recognize any gain or loss for
Federal income tax purposes. You may recognize gain upon such exchange if the
amount of your partnership's liabilities allocable to you, as determined
immediately prior to the exchange, in respect of the portion of units that are
treated as being transferred in a tax-free contribution exceeds the amount of
the AIMCO Operating Partnership liabilities allocated to you, as determined
immediately after the exchange. In this event, such excess would be treated as a
deemed distribution of cash from the AIMCO Operating Partnership to you. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of your adjusted tax basis in the OP Units received, and thereafter
as a taxable gain. You will have a holding period in the OP Units received
pursuant to the portion of the exchange that is treated as a tax free
contribution that includes the holding period of your units transferred in
exchange therefor.
 
TAX CONSEQUENCES OF EXCHANGING UNITS SOLELY FOR CASH
 
     In general, you will recognize gain or loss on a sale of a unit pursuant to
the offer equal to the difference between (i) your "amount realized" on the sale
and (ii) your adjusted tax basis in the units sold. The "amount realized" with
respect to a unit will be equal to the sum of the amount of cash received by you
for the unit sold pursuant to the offer (that is, the offer consideration) plus
the amount of the liabilities of your partnership allocable to such unit (as
determined under Section 752 of the Code). Thus, your tax liability resulting
from such sale of units could exceed the amount of cash received upon such sale.
 
ADJUSTED TAX BASIS
 
     In general, investors in your partnership had an initial tax basis in their
units equal to the cash investment in the partnership increased by their share
of partnership liabilities at the time such units were acquired. Your initial
tax basis generally has been increased by (i) your share of your partnership's
income and gains and (ii) any increases in your share of liabilities of your
partnership, and has been decreased (but not below zero) by (i) your share of
cash distributions from your partnership, (ii) any decreases in your share of
liabilities of your partnership, (iii) your share of losses of your partnership,
and (iv) your share of nondeductible expenditures of your partnership that are
not chargeable to capital. For purposes of determining your adjusted tax basis
in units immediately prior to a disposition of such units, your adjusted tax
basis in such units will include your allocable share of your partnership's
income, gain or loss for the taxable year of disposition. If your adjusted tax
basis is less than your share of your partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of your unit), your gain recognized
                                      S-51
<PAGE>   5053
 
pursuant to the offer will exceed the cash proceeds realized upon the sale of
such unit. The initial adjusted tax basis of the OP Units received by you in
exchange for your units pursuant to the offer will be equal to (i) the sum of
your adjusted tax basis in such transferred units plus any gain recognized in
the exchange and reduced by (ii) cash received or deemed received in the
exchange.
 
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
 
     Except as described below, the gain or loss that you recognize on a sale or
exchange of a unit pursuant to the offer generally will be treated as a capital
gain or loss and will be treated as long-term capital gain or loss if your
holding period for the unit exceeds one year. Long-term capital gains recognized
by individuals and certain other noncorporate taxpayers generally will be
subject to a maximum Federal income tax rate of 20%. If the amount realized with
respect to a unit attributable to your share of "unrealized receivables" of your
partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
depreciation recapture with respect to certain types of property. In addition,
the maximum Federal income tax rate applicable to persons who are noncorporate
taxpayers for net capital gains attributable to the sale of depreciable real
property (which may be determined to include an interest in a partnership such
as your partnership) held for more than one year is currently 25% (rather than
20%) to the extent of previously claimed depreciation deductions that would not
be treated as "unrealized receivables."
 
     If you tender units in the offer, you will be allocated a share of your
partnership's taxable income or loss for the year of tender with respect to any
units sold or exchanged. Thus, you will recognize ordinary income or loss in an
amount equal to your partnership's accreted income or loss allocable to such
unit. Although you will not receive a distribution with respect to any accreted
income, the offer consideration includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution under the terms of the AIMCO Operating Partnership's agreement of
limited partnership. Such allocation and any cash distributed by your
partnership to you for that year will affect your adjusted tax basis in your
unit and, therefore, the amount of your taxable gain or loss upon a sale of a
unit pursuant to the offer.
 
PASSIVE ACTIVITY LOSSES
 
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
 
     Accordingly, if your investment in your partnership is treated as a passive
activity, you may be able to shelter gain from the sale of your units pursuant
to the offer with such losses in the manner described below. If you sell all or
a portion of your units pursuant to the offer and recognize a gain on such sale,
you will be entitled to use your current and "suspended" passive activity losses
(if any) from your partnership and other passive sources to offset that gain. If
you sell all or a portion of your units pursuant to the offer and recognizes a
loss on such sale, you will be entitled to deduct that loss currently (subject
to other applicable limitations) against the sum of your passive activity income
from your partnership for that year (if any) plus any passive activity income
from other sources for that year. If you sell all of your units pursuant to the
offer, the balance of any "suspended" losses that were not otherwise utilized
against passive activity income as described in the two preceding sentences will
no longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. Accordingly, you should consult your
tax advisor concerning whether, and the extent to which, you have available
suspended passive activity losses from your partnership or other investments
that may be used to offset gain from the sale of your units pursuant to the
offer.

FOREIGN OFFEREES
 
     Gain recognized by a foreign person on a transfer of a unit for cash, OP
Units, or a combination thereof, pursuant to the offer will be subject to
Federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign person on the disposition. Amounts would be creditable
against the foreign person's Federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
 
     YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
APPLICABLE TO YOU AS A RESULT OF A SALE OR EXCHANGE OF UNITS PURSUANT TO THE
OFFER.
 
                               VALUATION OF UNITS
 
     We determined our cash offer consideration by estimating the proceeds that
you would receive if your partnership were liquidated. For this purpose, we
estimated the value of the property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization rate to
your partnership's annual net operating income. We determined an appropriate
capitalization rate using our best judgment, but our valuation is just an
estimate. In reaching the capitalization rate, we considered your property's
physical condition, location and above-market mortgage interest rates. In
addition, we considered the recent decline in the market for equity securities,
including those of REITs, and the decline in the availability of commercial
mortgage financing. Although the direct capitalization method is a widely
accepted way of valuing real estate, there are a number of other methods
available to value real estate, each of which may result in different valuations
of the property. The proceeds that you would receive if you sold your units to
someone else or if your partnership were actually liquidated might be higher or
lower than our cash offer consideration. We determined our cash offer
consideration as follows:
 
     - First, we calculated the value of the property owned by your partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's annual net operating income of $          for
       the period from January 1, 1997 to December 31, 1997 to derive a gross
       property value of $          . We selected a capitalization rate of
            %, based on our experience in valuing similar properties. The lower
       the capitalization rate applied to a property's income, the higher its
       value. We considered local market sales information for comparable
       properties, estimated actual capitalization rates (net operating income
       less capital reserves divided by sales price) and then evaluated your
       partnership's property in light of its relative competitive position,
       taking into account property location, occupancy rate, overall property
       condition and other relevant factors. The AIMCO Operating Partnership
       believes that arms-length purchasers would base their purchase offers on
       capitalization rates comparable to those used by us, however there is no
       single correct capitalization rate and others might use different rates.
       We subtracted from this gross valuation capital expenditures of
       $          to derive a gross property value of $          .
 
     - Second, we calculated the value of the equity of your partnership by
       adding to the gross property value the value, of the non-real estate
       assets of your partnership, and deducting the liabilities of your
       partnership, including mortgage debt and debt owed by your partnership to
       its general partner or its affiliates after consideration of any
       applicable subordination provisions affecting payment of such debt. We
       deducted from this value any taxes and certain other costs including
       required capital expenditures and deferred maintenance to derive a net
       equity value for your partnership of $          .
 
                                      S-53
<PAGE>   5055
 
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of units in the event of a liquidation of your
       partnership, based on the terms of your partnership's agreement of
       limited partnership. Our cash offer consideration represents the per unit
       liquidation proceeds determined in this manner.

                             FAIRNESS OF THE OFFER
 
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
 
     The general partner of your partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of your partnership makes no
recommendation whether you should tender or refrain from tendering your units.
However, the general partner of your partnership believes that our offer,
including the offer consideration, is fair to you. The AIMCO Operating
Partnership has retained Stanger to conduct an analysis of the offer and to
render an opinion as to the fairness to unitholders of the offer consideration
from a financial point of view. Stanger is not affiliated with AIMCO or your
partnership. Stanger is one of the leaders in the field of analyzing and
evaluating complex real estate transactions. However, we provided much of the
information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." You should make your decision whether to tender based upon a
number of factors, including your financial needs, other financial opportunities
available to you and your tax position.
 
                                      S-54
<PAGE>   5056
 
     The terms of our offer have been established by us and are not the result
of arms-length negotiations. In evaluating the fairness of the offer, the
general partner of your partnership and the AIMCO Operating Partnership
considered the following factors and information:
 
        1. The opportunity for you to make an individual decision on whether to
     tender your units in the offer and that the offer allows each investor to
     continue to hold his or her units.
 
        2. The estimated value of your partnership's property has been
     determined based on a method believed to reflect the valuation of such
     assets by buyers in the market.
 
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
 
        4. An evaluation of the financial condition and results of operations of
     your partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The offer is not expected to have an effect on
     your partnership's financial condition or results of operations.
 
        5. The method of determining the offer consideration which is intended
     to provide you with OP Units or cash that financially equivalent to your
     interest in your partnership, adjusted to reflect the expenses of the
     offer. See "Valuation of Units."
 
        6. The opinion of Stanger, a third party expert, that the offer
     consideration is fair to holders of units from a financial point of view.
     See "Stanger Analysis"
 
        7. The fact that the units are illiquid and the offer provides holders
     of units with liquidity.
 
        8. The fact that the offer provides holders of units with the
     opportunity to receive both cash and OP Units together.
 
        9. The fact that the offer provides holders of units with the
     opportunity to defer taxes.
 
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
 
        11. The estimated unit value of $       , based on an estimated value of
     your partnership's property of $       . The general partner of your
     partnership has no present intention to liquidate your partnership or to
     sell or finance your partnership's property. See "Background and Reasons
     for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $     current annualized distributions with respect to the
     Common OP Units are $2.25, and distributions with respect to your units for
     the six months ended June 30, 1998 were $3,543.69 per unit (equivalent to
     $7087.38 on an annualized basis). This is equivalent to distributions of
     $          per year on the number of Tax-Deferral      % Preferred OP
     Units, or distributions of $          per year on the number of Tax-
     Deferral Common OP Units, that you would receive in exchange for each of
     your partnership's units. Therefore, distributions with respect to the
     Preferred OP Units and Common OP Units that we are offering are expected to
     be        , immediately following our offer, than the distributions with
     respect to your units. See "Comparison of Ownership of Your Units and AIMCO
     OP Units -- Distributions."
 
     In evaluating these factors, the general partner of your partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. The terms of the
offer have been established by the AIMCO Operating Partnership and are not the
result of arms-length negotiations. See "Conflicts of Interest." The general
 
                                      S-55
<PAGE>   5057
 
     partner of your partnership and the AIMCO Operating Partnership believe
that the valuation method described in "Valuation of Units" provides a
meaningful indication of value for residential apartment properties although
there are other ways to value real estate. A liquidation in the future might
generate a higher price for holders of units.
 
     The future value of the OP Units received in the offer will depend on some
of the same factors that will affect the value of the units, primarily the
condition of the real estate markets. However, if you exchange your units for OP
Units, you will be able to liquidate your investment only by tendering your OP
Units for redemption after a one-year holding period or by selling your OP
Units, which may preclude you from realizing the full value of your investment.
 
FAIRNESS TO UNITHOLDERS WHO DO NOT TENDER THEIR UNITS
 
     The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. If you choose
not to tender any units, your interest in your partnership will remain
unchanged. The identity of the other limited partners of your partnership may
change. If the AIMCO Operating Partnership acquires a substantial number of
units pursuant to the offer, AIMCO may be in a position to influence voting
decisions with respect to your partnership. AIMCO has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
 
  General
 
     To assist holders of units in evaluating the offer, the general partner of
your partnership has attempted to compare the cash offer consideration against:
(a) the prices at which the units have been sold in the illiquid secondary
market; and (b) estimates of the value of the units on a liquidation basis. The
general partner of your partnership believes that analyzing the alternatives in
terms of estimated value, established based upon currently available data and,
where appropriate, reasonable assumptions made in good faith, establishes a
reasonable framework for comparing alternatives. Since the value of the
consideration for alternatives to the Offer is dependent upon varying market
conditions, no assurance can be given that the estimated values reflect the
range of possible values. See "Valuation of Units."
 
     The results of these comparative analyses are summarized in the following
chart. You should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; and the
capitalization rates that will be used by prospective buyers when your
partnership's assets are liquidated.
 
     In addition, these estimates are based upon certain information available
to the general partner of your partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the offer. The
assumptions used have been determined by the general partner of your partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding your partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of your partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar
 
                                      S-56

     apartment properties, the manner in which your partnership's property is
sold and changes in availability of capital to finance acquisitions of apartment
properties.

Cash Offer Consideration....................................    $

</TABLE>
 
  Prices on Secondary Market
 
     There is no active market for the units. The general partner of your
partnership is unaware of any secondary market activity in the units. Therefore,
any comparison to prices on the secondary market is not possible at the present
time.
 
  Estimated Liquidation Proceeds
 
     Liquidation value is a measure of the price at which the assets of your
partnership would sell if disposed of in an arms-length transaction between a
willing buyer and your partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of your partnership estimated the liquidation value of units using the
same direct capitalization method and assumptions as we did in valuing the units
for the cash offer consideration. See "Valuation of Units." The only significant
difference is that the general partner of your partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of your partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that your partnership's
property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of your partnership were sold at their book value, and that the net
proceeds of sale were allocated to your partners in accordance with your
partnership's agreement of limited partnership.
 
     The liquidation analysis assumes that the assets of your partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because your partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.
 
ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly,      % of the estimated liquidation proceeds are assumed to be
distributed to holders of units. See "Valuation of Units."
 
                                STANGER ANALYSIS
 
     We engaged Stanger, an independent investment banking firm, to conduct an
analysis and to render an opinion (the "Fairness Opinion") as to whether the
offer consideration for the units is fair, from a financial point of view, to
the unitholders. We selected Stanger because of its experience in providing
similar services to other parties in connection with real estate merger and sale
transactions and Stanger's experience and reputation in connection with real
estate partnerships and real estate assets. No other investment banking firm was
engaged to provide, or has provided, any report, analysis or opinion relating to
the fairness of our offer.

     Stanger has advised us that, subject to the assumptions, limitations and
qualifications contained in its Fairness Opinion, the offer consideration for
the units is fair, from a financial point of view, to the unitholders. We
determined the offer consideration, and Stanger did not, and was not requested
to, make any recommendations as to the form or amount of consideration to be
paid in connection with the offer.
 
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix A-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
 
     We imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." We have agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.

     discussed with property management personnel conditions in local apartment
rental markets and market conditions for sales and acquisitions of properties
similar to your partnership's property.
 
SUMMARY OF REVIEWS
 
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
 
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of your partnership's property during September 1998. In the
course of the site visit, the physical facilities of your partnership's property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
your partnership's property and local market conditions. Stanger also reviewed
and relied upon information provided by your partnership and AIMCO, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
 
     Stanger also reviewed historical operating statements for your
partnership's property for 1996, 1997, and for the six month period ending June
30, 1998, the operating budget for 1998 as prepared by your partnership and
discussed with management the current and anticipated operating results of your
partnership's property.
 
     In addition, Stanger interviewed management personnel of your partnership
and AIMCO. Such interviews included discussions of conditions in the local
market, economic and development trends affecting your partnership's property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of your partnership's property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering your partnership's property, and
expectations of management regarding operating results of your partnership's
property.
 
     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by your partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
 
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of your partnership of the estimated liquidation
values of units utilizing estimates prepared by your partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value estimated by the management of your partnership and that
normal and customary costs of property sale were incurred, that other balance
sheet assets (excluding amortizing assets) and liabilities of your partnership
were sold at their book value, and that the net proceeds of sale were allocated
between the general and limited partners in accordance with your partnership
agreement of limited partnership.
 
CONCLUSIONS
 
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the offer consideration to be paid for the units in
connection with the offer is fair to the unitholders from a financial point of
view.
 
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
 
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by your partnership, AIMCO, or the management of the
partnership's property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of your
partnership. Stanger relied upon the representations of your partnership and
AIMCO concerning,
 
                                      S-59
<PAGE>   5061
 
     among other things, any environmental liabilities, deferred maintenance and
estimated capital expenditure and replacement reserve requirements, the
determination and valuation of non-real estate assets and liabilities of your
partnership, the allocation of your partnership's net values between the general
partner, special limited partner and limited partners of your partnership, the
terms and conditions of any debt encumbering the partnership's property, and the
transaction costs and fees associated with a sale of the property. Stanger also
relied upon the assurance of your partnership, AIMCO, and the management of the
partnership's property that any financial statements, budgets, pro forma
statements, projections, capital expenditure estimates, debt, value estimates
and other information contained in this Prospectus Supplement or provided or
communicated to Stanger were reasonably prepared and adjusted on bases
consistent with actual historical experience, are consistent with the terms of
your partnership's agreement of limited partnership, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the partnership's property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that your
partnership, AIMCO, and the management of the partnership's property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
partnership's property is as improved; and that all calculations were made in
accordance with the terms of your partnership's agreement of limited
partnership.
 
     Stanger was not requested to, and therefore did not: (i) select the offer
consideration or the method of determining the offer consideration; (ii) make
any recommendation to your partnership or its partners with respect to whether
to accept or reject the proposed offer or whether to accept the cash, Preferred

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a subsidiary of AIMCO on
October 1, 1998, when AIMCO merged with Insignia. Accordingly, the general
partner of your partnership is an affiliate of the AIMCO Operating Partnership
and, therefore, has substantial conflicts of interest with respect to the offer.
The general partner of your partnership has a fiduciary obligation to obtain a
fair offer price for you, even as a subsidiary of AIMCO. It also has a duty to
remove the property manager for your partnership's property, under certain
circumstances, even though the property manager is also an affiliate of AIMCO.
The conflicts of interest include the fact that a decision to remove, for any
reason, the general partner of your partnership from its current position as a
general partner of your partnership would result in a decrease or elimination of
the substantial management fees paid to an affiliate of the general partner of
your partnership for managing your partnership's property. Additionally, we
desire to purchase units at a low price and you desire to sell units at a high
price. The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Such conflicts
of interest in connection with the offer and the operation of AIMCO differ from
those conflicts of interest that currently exist for your partnership. See "Risk
Factors -- Risks to Offerees Who Tender Their Units in the Offer -- Conflicts of
Interest with Respect to the Offer."
 
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
 
     We own the general partner of your partnership and the manager of your
partnership's property. The general partner of your partnership receives no fee
for its services as general partner but may receive reimbursement for expenses
generated in that capacity, and may receive fees for additional services from
your partnership. The property manager received management fees of $92,000 in
1996, $144,000 in 1997 and $94,787 for the first six months of 1998. The AIMCO
Operating Partnership has no current intention of changing the fee structure for
the manager of your partnership's property.
 
COMPETITION AMONG PROPERTIES
 
     Because AIMCO and your partnership both invest in apartment properties,
these properties may compete with one another for tenants. AIMCO's policy is to
limit its management to properties which do not compete with one another.
Furthermore, you should bear in mind that AIMCO anticipates acquiring properties
in general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts and other
operational efficiencies. In managing AIMCO's properties, the AIMCO Operating
Partnership will attempt to reduce such conflicts between competing properties
by referring prospective customers to the property considered to be most
conveniently located for the customer's needs.
 
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
 
     Certain provisions of AIMCO's governing documents, as well as statutory
provisions under certain state laws, could be used by AIMCO's management to
delay, discourage or thwart efforts of third parties to acquire control of, or a
significant equity interest in, AIMCO and the AIMCO Operating Partnership. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
 
FUTURE EXCHANGE OFFERS
 
     If the results of operations were to improve for your partnership under
AIMCO's management, AIMCO might be required to pay a higher price for any future
exchange offers it may make for units of your partnership. Although we have no
current plans to conduct future exchange offers for your units, our plans may
change based on future circumstances. Any such future offers that we might make
could be for consideration that is more or less than the consideration we are
currently offering.

                                YOUR PARTNERSHIP
 
GENERAL
 
     Yorktown Towers, Associates is an Illinois limited partnership which raised
net proceeds of approximately $5,300,000 in 1981 through a private offering. The

Insignia in October, 1998. There are currently a total of 56 limited partners of
your partnership and a total of 106 units of your partnership outstanding. Your
partnership is in the business of owning and managing residential housing.
Currently, your partnership owns and manages the single apartment property

such as washer/dryer, microwave, fireplace, and patio/balcony.
 
PROPERTY MANAGEMENT
 
     Since December 1993, your partnership's property has been managed by an
entity which is now an affiliate of AIMCO. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership's property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The management fee which your
partnership paid the property manager during 1996, 1997 and the first six months
of 1998 were $92,000, $144,000 and $94,787, respectively.
 
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
 
     Under your partnership's agreement of limited partnership, your partnership
is not permitted to raise new equity and reinvest cash in new properties.
Consequently, your partnership is limited in its ability to expand its
investment portfolio. Your partnership will terminate on December 31, 2050
unless earlier dissolved. Your partnership has no present intention to
liquidate, sell, finance or refinance your partnership's property within any
specified time period.
 
     Generally, your partnership is authorized to acquire, develop, improve, own
and operate your partnership's property as an investment and for income
producing purposes. The investment portfolio of your partnership is limited to
the assets acquired with the initial equity raised through the sale of units to
the limited partners of your partnership or the assets initially contributed to
your partnership by the limited partners, as well as the debt financing obtained
by your partnership within the established borrowing restrictions.
 
     An investment in your partnership is a finite life investment, with the
partners to receive regular cash distributions out of your partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of your partnership's real estate investments, if available.

replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building

borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."

bears interest at a rate of 9.84%. The mortgage debt is due in October 2001.

partner of your partnership to lend funds to your partnership. Currently, the
general partner of your partnership has no loan outstanding to your partnership.

partnership's property. The number of competitive properties in such an area
could have a material effect on the rental market for the apartments at your
partnership's property and the rents that may be charged for such apartments.

     Your partnership is party to a variety of legal proceedings related to its
ownership of the partnership's property and management and leasing business,

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Overview
 
     The following discussion and analysis of the results of operations and
financial condition of your partnership should be read in conjunction with the

June 30, 1997
 
     Net Income
 
     Your partnership recognized net income of $155,114 for the six months ended
June 30, 1998, compared to $28,750 for the six months ended June 30, 1997. The
increase in net income of $126,364, or 439.53% was primarily the result of
increases in rental revenue due to lower vacancy losses offset by a decrease in
other income.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$1,959,753 for the six months ended June 30, 1998, compared to $1,858,085 for
the six months ended June 30, 1997, an increase of $101,668, or 5.47%. This
increase was primarily due to an increase in occupancy.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $622,519 for the
six months ended June 30, 1998, compared to $679,717 for the six months ended
June 30, 1997, a decrease of $57,198 or 8.41%. This was primarily the result of
decreases in utilities, taxes, licenses and fees and furniture rentals.
Management expenses totaled $94,787 for the six months ended June 30, 1998,
compared to $88,520 for the six months ended June 30, 1997, an increase of
$6,267, or 7.08%. The increase resulted from increases in rental revenue as
management fees are calculated as a percentage of revenue.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $72,516 for the six months
ended June 30, 1998 compared to $98,078 for the six months ended June 30, 1997,
a decrease of $25,562 or 26.06%. The decrease is primarily due to a decrease in
office supply expenses.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $609,150 for the six months ended June 30, 1998, compared to
$613,272 for the six months ended June 30, 1997, a decrease of $4,122, or 0.67%.

31, 1996
 
     Net Income
 
     Your partnership recognized a net loss of $272,000 for the year ended
December 31, 1997, compared to a net loss of $75,000 for the year ended December
31, 1996. The decrease in net income of $197,000, or 262.67% was primarily the
result of decreased revenues.

     Rental and other property revenues from the partnership's property totaled
$3,769,000 for the year ended December 31, 1997, compared to $3,895,000 for the

     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $1,642,000 for
the year ended December 31, 1997, compared to $1,591,000 for the year ended
December 31, 1996, an increase of $51,000 or 3.21%. Management expenses totaled
$144,000 for the year ended December 31, 1997, compared to $92,000 for the year
ended December 31, 1996, an increase of $52,000, or 56.52%. In 1996, the
property was managed by a third party and in April of 1997 Insignia took over
management, which caused property management fees to increase.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $92,000 for the year ended
December 31, 1997 compared to $71,000 for the year ended December 31, 1996, an
increase of $21,000 or 29.58%. The increase is primarily due to an increase in
audit fees of $6,000 and an overall increase in various administrative expenses.
 
     Interest Expense
 
     Interest expense, which includes the amortization of deferred financing
costs, totaled $1,302,000 for the year ended December 31, 1997, compared to
$1,316,000 for the year ended December 31, 1996, a decrease of $14,000, or

31, 1995
 
     Net Income
 
     Your partnership recognized a net loss of $75,000 for the year ended
December 31, 1996, compared to a net loss $230,238 for the year ended December
31, 1995. The decrease of $155,238, or 67.43% was primarily the result of
increased revenues of approximately $161,000.
 
     Revenues
 
     Rental and other property revenues from the partnership's property totaled
$3,895,000 for the year ended December 31, 1996, compared to $3,733,693 for the
year ended December 31, 1995, an increase of $161,307, or 4.32%. This is
attributed to the property implementing a corporate suites program in 1996,
which offers furnished units at higher rates.
 
     Expenses
 
     Operating expenses, consisting of, utilities (net of reimbursements
received from tenants), contract services, turnover costs, repairs and
maintenance, advertising and marketing, and insurance, totaled $1,591,000 for
the year ended December 31, 1996, compared to $1,568,678 for the year ended
December 31, 1995, an increase of $22,322 or 1.42%. Management expenses totaled
$92,000 for the year ended December 31, 1996, compared to $66,229 for the year
ended December 31, 1995, an increase of $25,771, or 38.91%. Property management
fees are based on total revenue. In 1996, revenues increased which caused
property management fees to increase.
 
     General and Administrative Expenses
 
     General and administrative expenses totaled $71,000 for the year ended
December 31, 1996 compared to $110,703 for the year ended December 31, 1995, a
decrease of $39,703 or 35.86%. The decrease is primarily due to decrease in
professional service fees and general decrease in various administrative
expenses.

costs, totaled $1,316,000 for the year ended December 31, 1996, compared to

     Liquidity and Capital Resources
 
     As of June 30, 1998, your partnership had $1,380,272 in cash and cash
equivalents. Your partnership's principal demands for liquidity include normal
operating activities, payments of principal and interest on outstanding debt,
capital improvements, and distributions paid to limited partners. Your
partnership has adequate sources of cash to finance its operations, both on a
short-term and long-term basis.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, the general partner of your partnership is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner of your partnership is not
liable to your partnership or any limited partner for any acts performed or
omission to do any act which was done in good faith and in accordance with sound
business practices and your partnership's agreement of limited partnership. In
addition, except as specifically set forth in your partnership's agreement of
limited partnership, the general partner is not liable to the limited partners
because any taxing authorities disallowed or adjusted income, deductions or
credits in your partnership's income tax returns. As a result, unitholders might
have a more limited right of action in certain circumstances than they would
have in the absence of such a provision in your partnership's agreement of
limited partnership. The general partner of your partnership is owned by AIMCO.
See "Conflicts of Interest".
 
     Your partnership will indemnify and hold harmless the general partner from
any claim, loss, expense, liability, action or damage resulting from any act or
omission done in good faith and in accordance with sound business practices and
the terms of your partnership's agreement of limited partnership, including
without limitation, reasonable costs and expenses of litigation and appeal
(including reasonable fees and expenses of attorneys engaged by the general
partner in defense of such act or omission) but the general partner will not be
entitled to be indemnified or held harmless due to, or arising from, its fraud,
bad faith, gross negligence or malfeasance. As part of its assumption of
liabilities in the consolidation, AIMCO will indemnify the general partner of
your partnership and their affiliates for periods prior to and following the
consolidation to the extent of the indemnity under the terms of your
partnership's agreement of limited partnership and applicable law.
 
     Your partnership's agreement of limited partnership does not limit the
amount or type of insurance your partnership may purchase to cover the liability
of the general partners of your partnership.

     The following table sets forth the distributions paid per unit in the

  Transfers
 
     The units are not listed on any national securities exchange or quoted on
the NASDAQ System, and there is no established public trading market for the
units. Secondary sales activity for the units has been limited and sporadic. The
general partner of your partnership monitors transfers of the units (a) because
the admission of the transferee as a substitute limited partner in your
partnership require the consent of the general partner of your partnership under
your partnership's agreement of limited partnership, and (b) in order to track
compliance with safe harbor provisions to avoid treatment as a "publicly traded
partnership" for tax purposes. However, the general partner of your partnership
does not monitor or regularly receive or maintain information regarding the
prices at which secondary sale transactions in the units have been effectuated.
The general partner of your partnership estimates, based solely on the transfer
records of your partnership (or your partnership's transfer agent), that the
number of units transferred in sale transactions (i.e., excluding transactions
believed to be between related parties, family members or the same beneficial
owner) was as follows:

     If the offer had been made in such prior periods, there would not have been
any material difference in the compensation that would have been paid to the
general partner of your partnership, or the company paid to the property manager
or AIMCO and its affiliates.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
NOTE A -- BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements of Yorktown Towers
Associates as of June 30, 1998 and for the six months ended June 30, 1998 and
1997 have been prepared in accordance with generally accepted accounting
principles for interim financial information. Accordingly, they do not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments considered necessary for a fair presentation have been included and
all such adjustments are of a recurring nature.
 
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that accounting measurements at interim dates inherently
involve greater reliance on estimates than at year-end. The results of
operations for the interim periods presented are not necessarily indicative of
the results for the entire year.

To the Partners of
Yorktown Towers Associates (a Limited Partnership)
 
     We have audited the accompanying balance sheet of Yorktown Towers
Associates, as of December 31, 1997, and the related statement of operations,
changes in partners' deficit and cash flows for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Yorktown Towers Associates
at December 31, 1997, and the results of its operations and cash flows for the
year then ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Yorktown Towers Associates (the "Partnership") is an Illinois limited
partnership organized in November 1981 to acquire and operate a residential
property located in Lombard, Illinois.
 
     The General Partner ("General Partner") is MAERIL, Inc., an affiliate of
Insignia Financial Group, Inc.
 
  Allocation of Profits, Gains, Losses and Cash Distributions
 
     Pursuant to the terms of the Partnership Agreement, losses will be
allocated 99% to the Limited Partners and 1% to the General Partner. Profits
will be allocated in accordance with distributions of cash flow (as described
below). Profits from the sale, exchange or other distribution of the
Partnership's property will be allocated to the General Partner in an amount
equal to the greater of 1% of such profits or the amount of cash distributable
to the General Partner from any such sale or refinancing (as described below).
Losses from the sale, exchange or other distribution of the Partnership property
will be allocated 1% to the General Partner. The remaining sale, exchange or
other distribution profits and losses will be allocated to the Limited Partners.
 
     Distributions of cash flow of the Partnership will be allocated first to
the Limited Partners in an amount ranging from 5% to 14% per annum on a
non-cumulative basis of their aggregate capital contributions, and the balance
66 2/3% to the Limited Partners and 33 1/3% to the General Partner.
Distributions of proceeds arising from the sale or refinancing of the
Partnership property will be allocated 66 2/3% to the Limited Partners and
33 1/3% to the General Partner. However, all such distributions to the General
Partner are subordinated to the Limited Partners' receipt of their capital, plus
the stipulated return thereon.
 
  Loan Costs
 
     Loan costs of $538,000 incurred with the financing of the mortgage note
payable are included in "Other assets" and are being amortized on a
straight-line basis over the life of the loan. Accumulated amortization at
December 31, 1997 is $248,000.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
  Depreciation
 
     Depreciation is computed utilizing the straight-line method over an
estimated useful life of 10 to 40 years for buildings and improvements and 5
years for furniture and fixtures.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
                                      F-11

                           YORKTOWN TOWERS ASSOCIATES
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and such deposits are included in "Receivables and
deposits". Deposits are refunded when the tenant vacates the apartment if there
has been no damage to the unit.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Restricted Escrows
 
     1) Capital Improvement Reserves
 
     At the time of the refinancing of the mortgage note payable, $365,000 of
the proceeds were designated for "capital improvement escrows" for certain
capital improvements. During 1997, the balance in this escrow was withdrawn to
fund capital improvements at the property.
 
     2) Replacement Reserve Account
 
     In addition to the Capital Improvement Reserves, replacement reserves of
$147,000 were established with the refinancing proceeds. These funds were
established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. At December 31, 1997, the balance was $166,000.
 
  Investment Property
 
     The investment property is stated at cost. The Partnership records
impairment losses on long-lived assets used in operations when indicators of
impairment are present and the undiscounted cash flows estimated to be generated
by those assets are less than the assets' carrying amount. The impairment loss
is measured by comparing the fair value of the asset to its carrying amount.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Advertising Costs
 
     Advertising costs ($54,000 in 1997) are charged to expense as they are
incurred and are included in operating expenses.
 
NOTE B -- MORTGAGE NOTE PAYABLE (DOLLAR AMOUNTS IN THOUSANDS)

                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners of
Yorktown Towers Associates (a Limited Partnership)
 
     We have audited the accompanying balance sheet of Yorktown Towers
Associates, as of December 31, 1996, and the related statement of operations,
changes in partners' deficit and cash flows for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Yorktown Towers Associates
as of December 31, 1996, and the results of its operations and cash flows for
the year then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Yorktown Towers Associates ("Partnership") is an Illinois limited
partnership organized in November 1981 to acquire and operate a residential
property located in Lombard, Illinois.
 
     VMS Realty Investment Ltd. and VMS Realty, Inc., the Partnership's former
general partners, withdrew from the Partnership and transferred their
partnership interests to MAERIL, Inc., (the "General Partner") an affiliate of
Insignia Financial Group, Inc., effective February 23, 1995.
 
  Allocation of Profits, Gains, Losses and Cash Distributions
 
     Pursuant to the terms of the Partnership Agreement, losses will be
allocated 99% to the Limited Partners and 1% to the General Partners. Profits
will be allocated in accordance with distributions of cash flow (as described
below). Profits from the sale, exchange or other distribution of the
Partnership's property will be allocated to the General Partners in an amount
equal to the greater of 1% of such profits or the amount of cash distributable
to the General Partners from any such sale or refinancing (as described below).
Losses from the sale, exchange or other distribution of the Partnership property
will be allocated 1% to the General Partners. The remaining sale, exchange or
other distribution profits and losses will be allocated to the Limited Partners.
 
     Distributions of cash flow of the Partnership will be allocated first to
the Limited Partners in an amount ranging from 5% to 14% per annum on a
non-cumulative basis of their aggregate capital contributions, and the balance
66 2/3% to the Limited Partners and 33 1/3% to the General Partners.
Distributions of proceeds arising from the sale or refinancing of the
Partnership property will be allocated 66 2/3% to the Limited Partners and
33 1/3% to the General Partners. However, all such distributions to the General
Partners are subordinated to the Limited Partners' receipt of their capital,
plus the stipulated return thereon.
 
  Escrow for Taxes
 
     All escrow funds are currently held by the Partnership and are designated
for the payment of real estate taxes.
 
  Loan Costs
 
     Loan costs of $538,000 incurred with the financing of the mortgage note
payable are included in "Other assets" and are being amortized on a
straight-line basis over the life of the loan. Accumulated amortization at
December 31, 1996 is $171,000.
 
  Income Taxes
 
     The financial statements include only those assets and liabilities and
revenues and expenses which relate to the business of the Partnership. No
provision has been made for Federal income taxes since such taxes are the
personal responsibility of the partners.
 
  Depreciation
 
     Depreciation is computed utilizing the straight-line method over an
estimated useful life of 10 to 40 years for buildings and improvements and 5
years for furniture and fixtures.

                           YORKTOWN TOWERS ASSOCIATES
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Cash and Cash Equivalents -- Unrestricted Cash
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Restricted Cash -- Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease and considers the deposits to be restricted cash. Deposits
are refunded when the tenant vacates the apartment if there has been no damage
to the unit.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.
 
  Restricted Escrows
 
     1) Capital Improvement Reserves
 
     At the time of the refinancing of the mortgage note payable, $365,000 of
the proceeds were designated for "capital improvement escrows" for certain
capital improvements. At December 31, 1996 the balance in the escrow was
$301,000, which includes interest earned on these funds. Upon completion of the
scheduled property improvements, any excess will be returned to the property for
operations.
 
     2) Replacement Reserve Account
 
     In addition to the Capital Improvement Reserves, replacement reserves of
$147,000 were established with the refinancing proceeds. These funds were
established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. At December 31, 1996, the balance was $159,000.
 
  Investment Property
 
     The Partnership accounts for its investment property in accordance with
FASB Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to Be Disposed Of", which requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. The impairment loss is
measured by comparing the fair value of the asset to its carrying amount.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Advertising Costs
 
     Advertising costs ($66,000 in 1996) are charged to expense as they are
incurred and are included in operating expenses.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners of
Yorktown Towers Associates (a Limited Partnership)
 
     We have audited the accompanying balance sheet of Yorktown Towers
Associates, as of December 31, 1995, and the related statements of operations,
changes in partners' deficit and cash flows for the year then ended. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Yorktown Towers Associates
as of December 31, 1995, and the results of its operations and its cash flows
for the years then ended, in conformity with generally accepted accounting

A. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Yorktown Towers Associates ("Partnership") is an Illinois limited
partnership organized in November 1981 to acquire and operate residential
property located in Lombard, Illinois.
 
     VMS Realty Investment Ltd. and VMS Realty, Inc., the Partnership's former
general partners, withdrew from the Partnership and transferred their
partnership interests to MAERIL, Inc., (the "General Partner") an affiliate of
Insignia Financial Group, Inc., effective February 23, 1995.
 
  Allocation of Profits, Gains, Losses and Cash Distributions
 
     Pursuant to the terms of the Partnership Agreement, losses will be
allocated 99% to the Limited Partners and 1% to the General Partners. Profits
will be allocated in accordance with distributions of cash flow (as described
below). Profits from the sale, exchange or other distribution of the
Partnership's property will be allocated to the General Partners in an amount
equal to the greater of 1% of such profits or the amount of cash distributable
to the General Partners from any such sale or refinancing (as described below).
Losses from the sale, exchange or other distribution of the Partnership property
will be allocated 1% to the General Partners. The remaining sale, exchange or
other distribution profits and losses will be allocated to the Limited Partners.
 
     Distributions of cash flow of the Partnership will be allocated first to
the Limited Partners in an amount ranging from 5% to 14% per annum on a
non-cumulative basis of their aggregate capital contributions, and the balance
66 2/3% to the Limited Partners and 33 1/3% to the General Partners.
Distributions of proceeds arising from the sale or refinancing of the
Partnership property will be allocated 66 2/3% to the Limited Partners and
33 1/3% to the General Partners. However, all such distributions to the General
Partners are subordinated to the Limited Partners' receipt of their capital,
plus the stipulated return thereon.
 
  Escrows for Taxes
 
     All escrow funds are currently held by the Partnership and are designated
for the payment of real estate taxes.
 
  Loan Costs
 
     Loan costs of $538,337 are included in "Other assets" and are being
amortized on a straight-line basis over the life of the loan. Accumulated
amortization at December 31, 1995 is $93,589.
 
  Depreciation
 
     Depreciation is computed utilizing the straight-line method over an
estimated useful life of 10 to 40 years for buildings and improvements and 5
years for furniture and fixtures.
 
  Cash and Cash Equivalents
 
     The Partnership considers all highly liquid investments with a maturity
when purchased of three months or less to be cash equivalents. At certain times,
the amount of cash deposited at a bank may exceed the limit on insured deposits.
 
  Leases
 
     The Partnership generally leases apartment units for twelve-month terms or
less.

  Restricted Escrows
 
     1) Capital Improvement Reserves
 
     At the time of the refinancing of the mortgage note payable, $364,500 of
the proceeds were designated for "capital improvement escrows" for certain
capital improvements. At December 31, 1995, the balance in the escrow was
$379,615, which includes interest earned on these funds. Upon completion of the
scheduled property improvements, any excess will be returned to the property for
operations.
 
     2) Replacement Reserve Account
 
     In addition to the Capital Improvement Reserves, replacement reserves of
$147,200 were established with the refinancing proceeds. These funds were
established to cover necessary repairs and replacements of existing
improvements, debt service, out-of-pocket expenses incurred for ordinary and
necessary administrative tasks, and payment of real property taxes and insurance
premiums. At December 31, 1995, the balance was $152,106.
 
  Tenant Security Deposits
 
     The Partnership requires security deposits from all lessees for the
duration of the lease. Deposits are refunded when the tenant vacates the
apartment if there has been no damage to the unit.
 
  Investment Properties
 
     Prior to 1995, the investment property was carried at the lower of cost or
estimated fair value, which was determined using the higher of the property's
non-recourse debt amount, when applicable, or the net operating income of the
investment property capitalized at a rate deemed reasonable for the type of
property. In 1995 the Partnership adopted FASB Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of", which requires impairment losses to be recorded on long-lived assets used
in operations when indicators of impairment are present and the undiscounted
cash flows estimated to be generated by those assets are less than the assets'
carrying amount. The impairment loss is measured by comparing the fair value of
the asset to its carrying amount. The effect of adoption was not material.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Advertising Costs
 
     Advertising costs, $62,803 in 1995, are charged to expense as they are
incurred and are included in operating expenses.
 
  Fair Value
 
     In 1995, the Partnership implemented Statement of Financial Accounting
Standards No. 107, "Disclosure about Fair Value of Financial Instruments," which
requires disclosure of fair value information about financial instruments for
which it is practicable to estimate that value. The carrying amount of the
Partnership's cash and cash equivalents approximates fair value due to
short-term maturities. The Partnership estimates the fair value of its fixed
rate mortgage by discounted cash flow analysis, based on estimated borrowing
rates currently available to the Partnership. The carrying value of the mortgage
approximates its estimated fair value.

     The mortgage note payable is non-recourse to the Partnership and is secured
by pledge of the investment property and by pledge of revenues from the
property. The note may be repaid prior to maturity, including a prepayment
penalty of a minimum of 1% of the outstanding balance. It may not be repaid
prior to October 15, 1997.

interest in Insignia Properties Trust, with Apartment Investment and Management
Company ("AIMCO"), a publicly traded real estate investment trust. The merger
was completed effective October 1, 1998, and accordingly, as of that date AIMCO

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  [                         ]
 
Gentlemen:
 
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of
[                                        ] (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Common OP Units of the Purchaser, or        Preferred OP Units of the Purchaser,
or a combination of any of such forms of consideration. The limited partners of
the Partnership (the "Limited Partners") will have the choice to maintain their
current interest in the Partnership or exchange their Units for any or a
combination of such forms of consideration. The amount of cash, Common OP Units
or Preferred OP Units offered per Unit is referred to herein as the "Offer
Price."
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
                                       A-1
<PAGE>   5111
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       A-2
<PAGE>   5112
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
AIMCO
 
     AIMCO's Charter limits the liability of AIMCO's directors and officers to
AIMCO and its stockholders to the fullest extent permitted from time to time by
Maryland law. Maryland law presently permits the liability of directors and
officers to a corporation or its stockholders for money damages to be limited,
except (i) to the extent that it is proved that the director or officer actually
received an improper benefit or profit in money, property or services for the
amount of the benefit or profit in money, property or services actually
received, or (ii) if a judgment or other final adjudication is entered in a
proceeding based on a finding that the director's or officer's action, or
failure to act, was the result of active and deliberate dishonesty and was
material to the cause of action adjudicated in the proceeding. This provision
does not limit the ability of AIMCO or its stockholders to obtain other relief,
such as an injunction or rescission.
 
     AIMCO's Charter and Bylaws require AIMCO to indemnify its directors,
officers and certain other parties to the fullest extent permitted from time to
time by Maryland law. The MGCL permits a corporation to indemnify its directors,
officers and certain other parties against judgments, penalties, fines,
settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made a party by reason of their service to
or at the request of the corporation, unless it is established that (i) the act
or omission of the indemnified party was material to the matter giving rise to
the proceeding and (x) was committed in bad faith or (y) was the result of
active and deliberate dishonesty, (ii) the indemnified party actually received
an improper personal benefit in money, property or services or (iii) in the case
of any criminal proceeding, the indemnified party had reasonable cause to
believe that the act or omission was unlawful. Indemnification may be made
against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by the director or officer in connection with the proceeding;
provided, however, that if the proceeding is one by or in the right of the
corporation, indemnification may not be made with respect to any proceeding in
which the director or officer has been adjudged to be liable to the corporation.
In addition, a director or officer may not be indemnified with respect to any
proceeding charging improper personal benefit to the director or officer in
which the director or officer was adjudged to be liable on the basis that
personal benefit was improperly received. The termination of any proceeding by
conviction, or upon a plea of nolo contendere or its equivalent, or an entry of
any order of probation prior to judgment, creates a rebuttable presumption that
the director or officer did not meet the requisite standard of conduct required
for indemnification to be permitted. It is the position of the Commission that
indemnification of directors and officers for liabilities arising under the
Securities Act is against public policy and is unenforceable pursuant to Section
14 of the Securities Act.
 
     AIMCO has entered into agreements with certain of its officers, pursuant to
which AIMCO has agreed to indemnify such officers to the fullest extent
permitted by applicable law.
 
THE AIMCO OPERATING PARTNERSHIP
 
     The AIMCO Operating Partnership Agreement requires the AIMCO Operating
Partnership to indemnify its directors and officers (each an "Indemnitee") to
the fullest extent authorized by applicable law against any and all losses,
claims, damages, liabilities, joint or several, expenses (including, without
limitation, attorney's fees and other legal fees and expenses), judgments,
fines, settlements and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the AIMCO Operating Partnership. Such
indemnification continues after the Indemnitee ceases to be a director or
officer. The right to indemnification includes the right to be paid by the AIMCO
Operating Partnership the expenses incurred in defending any proceeding in
advance of its final disposition upon the delivery of an undertaking by or on
behalf of the Indemnitee to repay all amounts
 
                                      II-1
<PAGE>   5114
 
advanced if a final judicial decision is rendered that such Indemnitee did not
meet the standard of conduct permitting indemnification under the AIMCO
Operating Partnership Agreement or applicable law.
 
     The Partnership maintains insurance, at its expense, to protect against any
liability or loss, regardless of whether any director or officer is entitled to
indemnification under the AIMCO Operating Partnership Agreement or applicable
law.

ITEM 22. UNDERTAKINGS.
 
     (a) The undersigned registrants hereby undertake:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933, as amended;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, as amended, each such post-effective amendment
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the registrants' annual reports pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be permitted to directors, officers and controlling
persons of the registrants pursuant to the foregoing provisions, or otherwise,
the registrants have been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrants of expenses incurred
or paid by a director, officer or controlling person of the registrants in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrants will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
     (d) The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other
 
                                      II-3
<PAGE>   5117
 
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
     (e) The undersigned registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     (f) The undersigned registrants hereby undertake to not issue securities
under this registration statement in order to effect any "roll-up transaction"
(as such term in defined in paragraph (c) of Item 901 of Regulation S-K).
Furthermore, the undersigned registrants hereby undertake to supply by means of
a post-effective amendment all information concerning an offer to purchase
partnership interests in exchange for securities issued under this registration
statement, prior to commencing such an offer, if pursuant to the provisions of
subparagraph (iv), (vii) or (viii) of paragraph (c)(2) of Item 901 of Regulation
S-K, such offer fails to constitute a roll-up transaction.

Our reports dated February 23, 1998, contains an explanatory paragraph that
states that the accompanying financial statements have been prepared assuming
that the Partnership will continue as a going concern.  As discussed in Note E
to the financial statements, the Partnership is not generating sufficient cash
flows to meet its maturing debt service requirements, which raises substantial
doubt about its ability to continue as a going concern.  Management's plans in
regard to these matters are also described in Note E.  The accompanying
financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that might result from the outcome of this
uncertainty.
